Landscape-inclusive energy transition: Landscape as catalyst in the shift to renewable energy

Authors:

Abstract

Progress of the energy transition and degradation of landscapes is often mentioned in the same breath. This perceived degradation stems from the changing of familiar and cherished landscapes. Wind turbines, solar fields and other energy technologies change landscapes, driven by (inter)national energy transition targets to mitigate climate change. As a result, landscape is considered as an ‘obstacle’ by many agents of energy transition. This PhD thesis explores whether ‘landscape’ can turn from perceived obstacle into a catalyzer for the 21st century energy transition. This thesis provides the building blocks for a so-called ‘landscape-inclusive energy transition’. First, a method is presented to define regional energy transition targets based upon landscape characteristics and preferences of local stakeholders. Furthermore, literature on large-scale landscape transformation projects is reviewed to draw lessons for the energy transition. Finally, a typology of multifunctional solar fields is developed to improve decision-making on siting and design. These results inform defining energy targets, designing renewable energy projects, developing energy policies and supporting the realization of a landscape inclusive energy transition.

transition landscape is therefore an ‘obstacle’ to be overcome to
ensure energy targets are met. Southill Solar is a demonstration of
the contrary where the ‘obstacle’ landscape became a ‘catalyst’ in
the shift to renewable energy.
Southill Solar Landscape: evidence of socio-
spatial innovation
Northwest of Oxford, United Kingdom, lies the Cotswolds, a
designated area of outstanding natural beauty (AONB). This area
is characterized by small 17th century villages and manor houses in
a hilly landscape, consisting of medieval estates and ancient forest
patches. In 2012, the local sustainability cooperative of the village
Charlbury started a campaign to build a community solar power
plant. The cooperative proposed to build on a large linear plot of
grassland that undulates towards the river Evenlode. In the initial
design, most of the site was covered with photovoltaic (PV) arrays
in a low density. This design was rejected on grounds of negative
visual impact on the AONB. The cooperative decided to resubmit
the planning application. To address the issue of visual impact, the
cooperative organized a so-called ‘bring-your-brolly-day’ (brolly is
another term for umbrella). On this day, more than one hundred
local citizens (on a population of less than 3.000) marked various

layouts of the power plant with their umbrellas. Those umbrellas,
note the symbolic association with climate change, represented
the height of the proposed PV panels. Photographs from strategic
locations made it possible to identify the visibility of each of the

balanced with landscape objectives, such as visibility and habitat
improvement. The participatory approach won the yearly award of
the Landscape Institute (chartered body of landscape profession
in the United Kingdom) in the category local landscape planning
(Landscape Institute, 2015). Today, Southill Solar is still an exception,
in contrast with the mainstream practices of renewable energy
projects. More often than not, landscape is used as an argument for
opposing renewable energy projects and thus seems to represent
an obstacle to the energy transition. This is hardly surprising,
considering many development sites are selected for economic
reasons without understanding the meaning the landscape

(Devine-Wright, 2011b). Moreover, the great majority of sites with
planning approval are transformed to monofunctional power
plants with substantial impact on functions and values of landscape
(Selman, 2010).
This thesis therefore explores whether ‘landscape’ can turn from
perceived obstacle into a systemic catalyzer for the 21st century
energy transition. To this end, this thesis aims to identify key tenets
for a landscape inclusive energy transition, for advancing the energy
transition while meeting societal considerations regarding landscape.
Energy transitions and landscape transformation
Southill Solar is representative of the global ambition to shift
from fossil fuels to renewable energy sources (IRENA, 2022). In
the last decades, concerns about the global climate have led to
the signing of (inter)governmental agreements and the setting of
national and regional targets for renewable energy. The objective
of the Paris Agreement is to keep global temperature rise below

targets for a share of 32% renewable energy in 2030 (European
Parliament & European Council, 2018) and with the introduction of
the Green Deal, a target of 55% GHG emission reduction by 2030
was set (European Commission, 2021). In the Netherlands, these
targets led to the signing of the cross-sectoral, national climate
agreement (Klimaatakkoord, 2019). Representatives from the built
environment, industry, mobility, agriculture and land use, and the
electricity sector agreed upon emission reduction targets for 2030.

otherwise, energy landscape in this thesis refers to renewable energy
landscape. The past energy transitions have all led to distinct energy
landscapes, although energy has not always been the singular
driver for landscape transformation. Instead, transformation was
driven by multiple societal needs, for example land reclamation,
peat extraction and urbanization (De Jong & Stremke, 2020).

the energy transition of the 21st century is interconnected with
concerns such as human well-being, methods of production and

The current energy transition is and will continue to take place
in familiar and mundane, ‘lived landscapes’ (Sherren, 2021). The
term ‘lived landscapes’ refers to the places where people reside,

touch, taste and hearing (Van Etteger, 2016). As ‘scenery’, landscape
is mainly understood as a phenomenon that is visually perceived,

available areas for renewable energy provision. The result of climax
thinking is that challenges of today – such as the energy transition
– are pushed to communities living somewhere else or in the future
(Sherren, 2021).
Paradoxically, renewable energy developments are often wrapped
in the promise of temporality (Windemer, 2019). The end-of-life
stage of renewable energy technologies, such as wind turbines
and PV panels, is often reached in 20-30 years. This fact is used
by developers and/or governments to frame renewable energy
projects as temporary without explicitly stating what will happen
in the landscape once the end-of-life of the energy technology is
reached. This is problematic because the temporal character of

In much of todays’ energy transition discourse, landscape is either

that is negatively impacted by renewable energy infrastructure.

Textbox 1.1. Landscape dynamics of the Veluwe
The Veluwe is one of Europe’s largest continuous nature areas, located at
the center of the Netherlands. This push moraine complex is characterized
by forest, heath and sand drift areas. In 2016 the Veluwe was runner-up in
the election for the most beautiful nature area in the Netherlands. However,
most voters might not be aware that the Veluwe actually has a long
history of agricultural and industrial use that have caused this landscape
to change dramatically through the centuries. In pre-historic times the
Veluwe was an area with one of the highest population densities of the
Netherlands. Multiple cycles of over-exploitation, population decline and
re-cultivation changed the appearance of the Veluwe as a largely forested
area and relatively open heath landscape. The industrial use of the Veluwe
is evidenced by over 200 watermills that were located in the edges of the
Veluwe, making use of the elevation dierence. The water mills were used
for processing copper and wool and producing paper. In addition, wood
was processed in kilns to produce charcoal for harvesting iron ore that
was found in the loam layers. At the start of the 20th century the ‘wild’ and
uncultivated appearance of the Veluwe was qualied as ‘despicable’ by train
travelers who could perceive the Veluwe on their journeys. This changed
when people started to appreciate the ‘unspoiled’ life outside the city and
areas such as the Veluwe were romanticized by painters and writers. Hotels,
pensions and sanatoria emerged at the Veluwe. Currently the Veluwe is an

These developments make clear that stakeholders in the energy
transition, particularly inhabitants, governments, cultural and
environmental NGO’s as well as other landscape users, have become
aware of the current disregard of landscape in the energy transition
discourse. Through research, code of conducts, policies and
guidelines, and local debates, these stakeholders stress the need to
feature ‘landscape’ more prominently in the energy transition. They
propose and, at times demand that their considerations are taken
into account during the planning and design of energy landscapes.

Horst, 2010). Including landscape in the energy transition discourse
– according to Paul Selman’s paper entitled Learning to love the
landscapes of carbon-neutrality – can “display placeness and tell a
story of human ingenuity, adaptation and wisdom that is intrinsically
worthy of pride” (Selman, 2010).

Textbox 1.2. Alternatives to ‘landscape’?
Landscape, admittedly, is a complex concept and this might raise the
question if the concept should not be abandoned altogether, in favor of
other terms that are better equipped to address the implications of the
energy transition to people’s surroundings.
Space for example, is a term that is often used interchangeably with
landscape, especially in the context of ‘spatial impact’ or ‘spatial dimensions’
of the energy transition. Used like this illustrates the rather abstract
meaning of space. Bridge et al. (2013) for example, ‘unpack’ the spatiality
of the energy transition, amongst others, using the word landscape. Some
disciplines use space primarily quantitative, which makes it a useful concept
to compare spatial footprints of dierent energy technologies and illustrate
the scale of the energy transition.
In line, Tuan (1977) argues that space is rather abstract and focuses on
the physical surroundings, while place focuses on the meanings associated
with space and is therefore human centered and personal (Tuan, 1977).
Although place highlights the personal attachments of people to their
surroundings, it has less emphasis on the natural and cultural, physical
characteristics.
Environment is often used in a similarly abstract way, usually referring to
the natural environment but is also used in other ways, for example social
environment or neighborhood environment. Either way, environment refers
to everything around an organism (e.g. human or plant) and usually does
not convey the meanings that organism attaches to the environment.
Another candidate term is land, which is a closely related term that points
towards a piece of terrain that is owned by someone (Antrop & Van
Eetvelde, 2017). Land is thus relevant for the energy transition, because
ownership of land is an important aspect in decision-making. However,
‘land’ largely lacks qualitative notions: “you can ask of land how much there
is, but not what it is like” (Ingold, 1993, p. 153).
Territory it etymologically linked to land (‘terra’ means ‘land’) and refers to a
delimited area governed by political or social power (Antrop & Van Eetvelde,
2017; Bridge et al., 2013). This is a useful term in the energy transition,
because what happens in a territory is often governed by multiple levels
of power (e.g. EU legislation and municipal laws). However, similar to land,
the English term territory hardly conveys the interpretation and experience
of individuals and groups of their surroundings. In other words, “interest
groups dealing with the same territory of land see dierent landscapes.”
(Antrop & Van Eetvelde, 2017, p. 41).

it is currently used in much of the energy transition discourse. The

are a relatively new phenomenon and their interaction with

construction of solar power plants (SPP) has increased over the past
decade (Comello, Reichelstein, & Sahoo, 2018). Discussions revolve
around land use competition as well as environmental and visual
impacts, which has started to give rise to dedicated SPP research

The second knowledge gap concerns the spatial properties of so-
called ‘solar landscapes’. While a solar power plant can have multiple
purposes, key to the concept of ‘solar landscapes’ is the “design
of solar power plants as landscape” (Scognamiglio, 2016, p. 638).

or recreation functions in relationship to characteristics of the
existing landscape, or creating new, distinct patterns. The concept
of ‘solar landscape’ connects back with Sylvia Crowe who in the
1950s started to argue for designing ‘complete landscapes’, instead
of mitigating inertia between technology and landscape (Crowe,
1958, p. 24). Some studies have presented single, theoretical cases

and developing energy policies. This overall knowledge gap points
to the need for what is in this PhD thesis referred to as landscape
inclusive energy transition: an energy transition that embraces a

transition, it is unclear whether and how landscape can turn from
a perceived obstacle into a systemic catalyzer for the 21st century
energy transition.
This thesis therefore aims to identify key tenets for a landscape
inclusive energy transition, for advancing the energy transition while
meeting societal considerations regarding landscape. The use of the
term tenets implies that this PhD thesis does not aspire to articulate
fully established axioms or undisputable dogmas. Rather, this thesis
provides new knowledge and directions for continued innovation in
research, policy and practice, towards a more landscape inclusive
energy transition.

This thesis is built upon a pragmatic worldview. This worldview
acknowledges the existence of both a ‘real’ world and a ‘socially
constructed’ world (Crotty, 1998) and its proponents are concerned
with ‘what works’ and real-world problem solving (Creswell, 2009).

For the embedded case studies, a case study protocol was

Data triangulation was used in the case studies to ensure the
validity of the spatial analysis of solar power plants. Initial analysis

Abstract
Climate change, depletion of fossil fuels, and economic concerns
are among the main drivers of sustainable energy transition. Over
the past decade, several regions with low population density have
successfully transited towards renewable energy (for example
Siena, Italy). In the Netherlands and other countries, more densely
populated regions have drawn up ambitious targets for energy
transition. Most of these transition targets lack empirical evidence
with regard to spatio-technological feasibility. This lack of evidence
may compromise energy transition if constraints are discovered
posteriori and short-term milestones missed. To address this
shortcoming, we propose an integrated approach. Spatial Transition

2.1Introduction
Climate change, depletion of fossil fuels and concerns about local
economies are among the main drivers of sustainable energy
transition (Bridge et al., 2013). This transition is not limited
to the transformation of energy infrastructure, but involves
transformations of “the broader social and economic assemblages
that are built around energy production and consumption” (Miller
et al., 2013, p. 135) and is being increasingly studied by social
scientists, geographers, spatial planners, landscape architects and

landscape refers to “an area, as perceived by people, whose
character is the result of the action and interaction of natural and/
or human factors” (Council of Europe, 2000, p. 2).
In Europe, several regions have successfully transitioned towards
renewable energy, for example Siena, Italy (Casprini, 2013) and

Examples in the Netherlands are Stedendriehoek (Pijlman &
Bosman, 2014) and the cities Utrecht (Gemeente Utrecht, 2011)
and Groningen (Gemeente Groningen, 2008) aiming to achieve
100% energy or carbon neutrality by 2030 or even 2025. Energy
neutrality refers to “the extent to which a district […] can supply
itself with sustainable energy generated within the boundaries
of that district” (Jablonska et al., 2011, p. 1). Regions are often
unaware whether spatial characteristics of the region are suitable
to achieve energy neutrality (e.g. “Energietransitienota Duurzame

technological feasibility. Furthermore, many targets are conceived
without involving stakeholders. Considerations of stakeholders with
regard to the way the energy transition should take place are not
taken into account. Such bold and superimposed transition targets
may compromise energy transition if constraints are discovered
posteriori and short-term milestones are missed. To illustrate, the
target of the municipality Groningen (the Netherlands) has already
been adjusted from 2025 to 2035 (Gemeente Groningen, 2011).

energy transition. To address the shortcomings of current practice,
STA ought to be spatially explicit, evidence-based with regard to
renewable energy technologies (RET), and inclusive of stakeholder
values and preferences.
Several concepts, methods and approaches have provided building
blocks for the research presented in this paper. Departing from
the concept of ‘energy landscape’, (Stremke, 2015) introduced a
conceptual framework for the planning and design of sustainable
energy transition. He stresses that four dimensions (or types)
of criteria should be addressed in the planning and design of
sustainable energy landscapes, namely environmental, socio-
cultural, economic and technical criteria. This typology will be
revisited later in the paper.

Strategic planning and design provided the theoretical foundations
of the research presented in this paper (see for example Albrechts,
2004). The Five Step Approach is a methodological framework
for strategic design that has been applied to envision regional
energy landscapes (Stremke, Koh, Neven, & Boekel, 2012). For this,
three modes of change, namely current projected trends, critical
uncertainties and intended change are integrated in a design
process that explores alternative pathways for the realization of
transition targets (Stremke, van Kann, & Koh, 2012). In this paper
the focus is on how such targets can be determined.

One of the aims of conducting interviews with local stakeholders
is to gather spatially explicit data on potentials, constraints and
the existing supply of renewable energy sources. Another aim is
to collect information on stakeholder preference and aversion
regarding RET. The output may consist of local (GIS) data, municipal

Year of energy neutrality
The aim of Step Seven is to link the results of the renewable
energy study (as presented in this paper) with the current energy
consumption and potential energy savings. Together, they make
it possible to determine the possible year of energy neutrality.

local renewable energy provision exceeds local energy consumption,
energy neutrality is achieved. Data used in this step are the results

The outcome of Step Seven is an indication of the potential year of
energy neutrality for a study area.

energy sources’, ‘economic feasibility’ and the ‘preservation of
cultural heritage sites’ were considered important criteria that
should be taken into account for the sustainable energy transition
in this region. Other criteria such as ‘minimize land use competition’
and ‘maintain potentials for recreation and ecotourism’ were
considered important to some extent. The relatively high average of
criteria indicates a desire to develop a sustainable energy landscape,
even though some respondents considered particular criteria less
important than others. Clearly, there is consensus and a positive
attitude towards the use of locally available renewable energy
sources. Landscapes with high scenic values should be considered
carefully during the transition.
Selection of renewable energy sources and technologies
Five renewable energy sources were studied in detail for the
Parkstad Limburg region: solar, wind, heat-cold storage, hydropower
and biomass. Deep geothermal energy was excluded for two
reasons: a lack of reliable data on geothermal potential and the very
low potential indicated in the few references that were available.

cultural heritage sites’ were considered important criteria that
should be taken into account for the sustainable energy transition
in this region. Other criteria such as ‘minimize land use competition’
and ‘maintain potentials for recreation and ecotourism’ were
considered important to some extent. The relatively high average of
criteria indicates a desire to develop a sustainable energy landscape,
even though some respondents considered particular criteria less
important than others. Clearly, there is consensus and a positive
attitude towards the use of locally available renewable energy
sources. Landscapes with high scenic values should be considered
carefully during the transition.

Energy potential mapping
For solar and wind energy, heat-cold storage, hydropower and
biomass, the potentials and constraints were illustrated in one
map each (1:25.000). Figure 2.6 shows the map that was created for
solar energy. This map indicates that the entire region falls within
a zone of 1450–1500 h of sunshine per year. Roofs of residential,
public and commercial buildings and industrial plants are suitable
for both PV panels and solar thermal collectors. The map depicts
settlements with heritage status as well as landmarked buildings.

and normative constraints. Biomass (2%) contributes relatively
little and consists of second-generation biomass only. Yet, even

this spatial delineation remains somewhat arbitrary since the
collaboration with other regions may provide additional value in
the light of energy transition. Electricity exchange, for example,
could help to deal with the intermittent character of wind and solar

to autarkic regions, are well connected with other regions in order
to create robust energy systems.

attitudes towards renewable energy technologies may change in
time due to new insights, changing value systems or other factors
(ETSU, 1993). Therefore, it is suggested to monitor developments
throughout the transition and adjust measures where needed.
Similarities and differences between STA and other approaches
This paper shows how a target for energy transition can be
established by researching the potentials for renewable energy
provision and energy savings. Qualitative considerations of
stakeholders and experts are included in the STA, together with
the particular bio-physical characteristics of Parkstad Limburg.
In doing so STA expands on the work of (Wang et al., 2014) who

preferences. Blaschke et al. (2013) too uses GIS maps and
distinguishes between ‘technical’ and ‘realistic’ potentials. The latter,
however, is solely based on expert judgement and not informed
by stakeholder preferences. Similar to van den Dobbelsteen et al.
(2011), STA illustrates renewable energy potentials through maps.

as the visual assessment of potential interventions (for example A.
Grêt-Regamey & Wissen-Hayek, 2013) can be carried out once the

the STA was conducted in a relatively short amount of time and at
an early phase of the regional energy transition. As a matter of fact,
it marked the start of the planning process. The research provided
the foundations for a joint political ambition (the target) while
contributing to capacity building in the region. If reliable (GIS) data

Abstract
The transition to renewable energy is a powerful driver for
large-scale landscape transformation. Environmental design is
increasingly concerned with this transition, but little is known
about purposefully designed renewable energy landscapes.
To improve the design of large-scale energy landscapes we
reviewed the literature on three innovative large-scale landscape
transformations: Room for the River Nijmegen-Lent (The
Netherlands), Queen Elizabeth Olympic Park (UK) and Freshkills

(Council of Europe, 2000, p. 2). Landscape transformation involves
a change in the dominant land use and the visual appearance of
the landscape. Environmental design disciplines are active in an
increasing number of landscape transformations. These disciplines,
such as landscape architecture, urban design, spatial planning
and architecture are concerned with the conscious shaping of
the environment. Examples of designed transformations are the
remediation of post-industrial landscapes (e.g. Landscape Park
Duisburg Nord in Germany), urban regeneration (e.g. Madrid RIO

These targets will necessitate large-scale landscape transformations
in denser populated areas (for the Dutch situation see Sijmons et
al., 2017). Up until now, energy transition in denser populated areas
is somewhat limited to small-scale renewable energy interventions
(e.g. groups of wind turbines in business areas), while large-scale
interventions are often located in remote areas (e.g. utility scale

environmental design is increasingly engaged with renewable

transformations aims to inform the design of large-scale renewable
energy landscapes. In literature on energy landscapes, amongst
others, three aspects are considered to be of critical importance:
governments (Leibenath & Lintz, 2018), design (Stremke &
van den Dobbelsteen, 2013) and participation (Devine-Wright,
2011a). We found the same aspects in the literature on the three
aforementioned large-scale landscape transformation projects.

In each case, governmental bodies (in a multi-level governance
constellation) proposed a landscape transformation and employed
design to give form to the intended change. Local stakeholders
were involved to various degrees. All four research components

Governments
Political considerations, economic development and environmental
concerns have fueled a reorganisation of government in much of the
Western world (Albrechts, Healey, & Kunzmann, 2003). Government
decentralization has led to increased planning responsibilities of
local authorities, and involvement of economic parties and civil
society in decision-making (Healey, Khakee, Motte, & Needham,

We found that interactions between multiple tiers of government
featured prominently in the cases. Interactions with non-state
actors reported in the literature were mainly concerned with the
participation of local stakeholders (see section 3.3.4). During the
literature analysis, we considered the roles of government at the
local, mid-level, national and supranational levels as well as the
interaction between these levels.

masterplan. We based our analysis of the design aspect in the

Park, Pollak (2007, p. 89) argues that for transformations of such
scale, the perspective of a “stable whole” is an illusion and that the
identity of the site is dynamic and heterogenic.

On Olympic Park, the objective of the Legacy Masterplan Framework
(LMF) was to guide development after the Olympic Games and
it formed the basis for other spatial visons. Davis (Davis, 2011)
stresses the absence of alternative scenarios in the LMF, as well
as the absence of clear evaluation criteria for the proposed spatial
scenario. For Freshkills Park, Hutchinson (2015) reports on the
lack of investigated alternative options to a park. The literature
on Nijmegen-Lent reports that alternative designs were evaluated
but that design criteria were either disputed (Winnubst, 2011) or
unknown to the inhabitants (Cuppen & Winnubst, 2008). In addition,

The design process for Nijmegen-Lent was controlled by the
designers (Heeres et al., 2017), who worked in tandem with the
process manager (Hulsker, Wienhoven, van Diest, & Buijs, 2011).
Experienced designers in the role of lead designer and as part of
the Q-team functioned as links between the technical design and
the integrative spatial design. An overall collaborative approach
to design is reported, which resulted in shared solutions and the
support by engaged inhabitants (Heeres et al., 2017).
The design competition for Freshkills Park served as an impetus
for the transformation, which suggests that in this project a similar
importance is attributed to designers. Environmental designers led
an large multidisciplinary team and their work is mentioned as one
of the key drivers guiding the shape of the park (Hutchinson, 2015).
However, May (2008) states that design is being used to recast the
image of Freshkills Park in “the collective memory of a population”,
with the result that the “horrible realities of our Modern American

These contingencies “changed the ideas of what a park should
be” (Hutchinson, 2015, p. 169): a new range of values, roles and
functions are now associated with parks.

participatory process was subordinate to the political process
(Cuppen & Winnubst, 2008).
Similarly, the literature on Freshkills Park reports placation,
consultation and informing. Consultation resulted in “consensus
building in the community and ultimately encouraged support for
the reclamation” (De Sousa & D’Souza, 2011) and the inclusion of
public preferences in the masterplan (Sugarman, 2009).
Participation and design
In Nijmegen-Lent, environmental designers invested in building
professional relationships with inhabitants (by means of e.g.
excursions), which enabled a mutual exchange of thoughts on
important issues. Overall, participation is reported to have had a

Public meetings on Freshkills Park revealed community preferences,
including renewable energy provision, an educational programme
(De Sousa & D’Souza, 2011) and the parks infrastructure
(Hutchinson, 2015). Some of those functions, it has been argued,
may have otherwise been introduced by governmental authorities

Indication of resistance
In addition to these participation strategies, we found evidence of
confrontation between inhabitants and governments. Inhabitants
were reportedly pro-active in demanding a role in the planning
process for Nijmegen-Lent, in response to the initial plan to
demolish 50 houses (Winnubst, 2011). This confrontational
approach was fueled by local attitudes to government based on
the previous experience of the annexation of the small town of

the suitability of the site as a park (Hutchinson, 2015). Resistance to
Olympic Park focused on the relocation of existing land uses, such
as allotments and cycling facilities. Opposition was also fueled by
an evaluation of the existing landscape that was not shared by local
stakeholders (Davis, 2011) and the radical changes to the landscape
for inhabitants (Hoolachan, 2017).

Design of large-scale landscape transformations
The literature on the three projects points to a central and integrative
role of design. However, we expected certain topics related to design
and designing to be discussed more extensively in the literature
on large-scale landscape transformations. Firstly, literature only
incidentally referred to the use of evidence-based scenarios or
alternative futures to facilitate the initiation of change (3.3.3).
Contrastingly, an increasing number of scholars are concerned with

2012). This suggests a gap between current scholarly thinking and
design practice. Secondly, the reviewed literature stresses that
criteria to evaluate design(s) are either absent, unknown to, or
disputed by local stakeholders. Stremke (2015, p.7) argues that for
the design of energy landscapes “criteria have to be selected, made
explicit, and prioritised by stakeholders and experts”. The literature
on the three landscape transformations reveals no attempts to
accomplish such systematic and transparent evaluation. Thirdly,

multifunctionality as a consistent and sustained objective in large-
scale landscape transformations. Recent research suggests that
multifunctionality is also a characteristic of certain types of energy
landscapes: landscapes with wind turbines are an example of so-
called ‘component energy landscapes’ that feature concurrent land
uses. ‘Entity energy landscapes’ such as surface coal mines, on the
contrary, are characterised by a mono-functional land use and

cases, however, are large, distinct landscape entities that comprise
multiple land uses. This opens up the possibility of future large-
scale renewable energy landscapes that may embody the spatial
expanse and physical boundaries of entity energy landscapes and
yet permit the multifunctionality of component energy landscapes.
This would enable a scaling up of the energy transition in some

Participation versus co-creation
Participatory strategies have been employed with varying degrees of
success. The literature suggests that participation was used mainly
in a one-way fashion, rather than to encourage active engagement
in the design process. Literature also reports the use of rather
conventional methods, such as public meetings, workshops and
site visits. Advanced approaches to engage stakeholders, such
as web-based decision support tools (e.g. Grêt-Regamey et al.,
2017) or participatory mapping (e.g. Stremke & Picchi, 2017), are
not mentioned. Quite the contrary has been described: during

Environmental designers played an important role in analysing the
existing site and developing designs for the landscape. Nevertheless,
the literature shows that important decisions were made before
environmental designers have been involved. Also, external events
and conditions led to changes in the design, or to alterations of
functions and values ascribed to the transformation.
The role of participation in the transformation projects was
limited and participation strategies were somewhat limited to
consultation and informing. While literature indicates that inclusion

The review showed that the large-scale character of the landscape
transformation complicates the development of a new and yet
meaningful landscape character. Distinctive for the transition
to renewable energy (as opposed to the three cases) is that
standardised technological and currently unfamiliar objects are
introduced into the landscape. Introduction of energy technologies,

Abstract
Solar power plants transform the existing landscape. This landscape
change raises concerns about visual impact, land use competition
and the end-of-life stage of solar power plants. Existing research
stresses the need to address these concerns, arguing for a
combined spatial arrangement of solar power plant and landscape:

Introduction
Solar power plants (SPP) have been constructed at an increasing
rate over the past decades (Comello et al., 2018). These power
plants, consisting of ground-mounted photovoltaic (PV) arrays and
electrical infrastructure, transform the landscape (Carullo, Russo,

multifunctionality and temporality. Visibility refers to whether an SPP
is observable by landscape users from a certain location (Apostol,

Lobaccaro et al. (2019) is the only study that examines spatial
properties of built solar landscapes. They partly address visibility

this paper: what are the visual, functional and temporal properties of
frontrunner solar landscapes in Europe?
This research aims to contribute to the growing body of knowledge
on solar landscapes by analyzing and comparing the spatial
96 | Landscape-inclusive energy transition
properties of constructed solar landscapes in Europe. This study
used expert consultation and desk-study to identify so-called
‘frontrunner’ SPPs. Insights in the innovative properties of these
frontrunner cases constitute a vital contribution to the debate
on how societal concerns about SPP can be resolved. Due to the
novelty of the topic, an analytical framework was developed for the
case study, based on a literature review. This framework focusing on
visibility, multifunctionality and temporality of SPP may also enrich
environmental impact assessments and multi-criteria decision
analyses of SPP in response to prominent societal concerns.
Furthermore, a better understanding of frontrunner cases, in
combination with the cultivation of solar landscape vocabulary, is
believed to support policy and decision makers, SPP developers,
designers and other stakeholders to conceive solar landscapes

Case-study approach
This study examines the spatial properties of built solar landscapes.
We adopted a case-study approach in our research, as this allows
for the description of a contemporary phenomenon in its spatial
context (Yin, 2009). We used a multiple embedded case design to
document and compare a high variety of spatial properties across
all cases (Yin, 2009).

Case selection
Our research focuses on the Netherlands, the United Kingdom,
Germany and Italy, as these countries have shown increasing
attention for solar landscapes. In addition, the travel distance
and language of these countries allowed us to study the cases
within the time and resource provided. We aimed to study cases
of SPP that were recognized for being at the front of addressing
societal concerns and providing functions additional to electricity

the host landscape in the case, (2) active management of landscape
features during operation and maintenance stage and (3) plans for
the decommissioning stage.

the way the system layout responded to the pattern of the host

single plot (Monreale). In the other eight cases, solar infrastructure
was distributed over multiple plots, whether the cases were
small (e.g. Sinnegreide, 12 ha) or large (e.g. Gänsdorf, 181 ha). In

In the split con guration, the patch responded to the shape of the
plot, yet only partially covered the plot area (25-50%). This partial
coverage resulted in a perceived split of the original plot. In Southill
for example, only the south-western part of the plot was used for
arrays, the remainder of the plot consisted of landscape features.

Array orientation, dimensions and materials
On the level of arrays, we found that in all cases the orientation of
the PV arrays was optimized for maximum solar energy generation.
This optimization was for 10 cases east-west oriented arrays facing
south, and for one case with a single-axis tracker north-south
oriented arrays (table 4.4, see also table 4.1). In other words, the
type of pattern was the same for all the cases: parallel stripes

Agricultural features
Nine cases included agricultural features, ranging from small fruit
tree orchards to substantial olive groves. This high presence of
agricultural features may point to addressing the loss of agricultural
land (Chiabrando et al., 2009). In Monreale, a large olive grove was
located next to the solar system, and the left-over spaces within the
solar system were planted with olive and almond trees. In Gänsdorf,
the case comprised a part of the former arable land. In three
cases (Laarberg, Hemau and Midden-Groningen) sheep were kept

Reflections on landscape features across frontrunner SPPs
Laarberg includes multiple categories of landscape features:
ecological, recreational, agricultural and water retention features
have been combined with electricity generation on only 6,4 ha.
Southill, on the contrary, displays focus on a single category: ecological
restauration is central and to this end human access is limited.
Furthermore, in Southill and Hemau spaces suitable for
electricity generation have been deliberately kept free to achieve
ecological objectives. In other words, spatial arrangement of solar
infrastructure is adjusted and even sub-optimal to accommodate

Solar landscape
Three emergent properties that arise from the combined spatial
arrangement of SPP and landscape – in this paper and elsewhere
conceptualized as solar landscape – are presented in this section:
visibility, multifunctionality and temporality.
Visibility
This section presents the visibility of the solar infrastructure based
on an analysis of the existing and new landscape features at the
edge of the solar landscape.
The edge
The edge of the cases consisted of existing eye-level vegetation
(appendix D) and new edge measures (appendix E), and in each
case the solar infrastructure was completely surrounded by a fence.
Existing eye-level vegetation, such as forest patches or hedgerows,

existing eye-level vegetation along the edge. New edge measures
consisted of landscape features, for example hedgerows or a reed
zone. Three types of measures were applied in the cases: removal of
existing landscape features, enhancing existing landscape features
and new landscape features (appendix E).
Reducing visibility of solar infrastructure
In all cases, the visibility was deliberately reduced, either through
siting within existing vegetation or through new edge measures with

used for screening purposes. This combination supports the notion

provided other functions as well. For example, in Gänsdorf an
orchard was planted to reduce visibility from the road and at the
same time produce fruit.

mainly negative impact into a potential positive impact.
Multifunctionality
Solar landscapes that provide functions additional to electricity
generation can be considered multifunctional. In this section, we

Groningen, multifunctionality is arranged as a sharp spatial
distinction between the high-density PV patches and livestock (array
and patch multifunctionality), and ecological features in the edge
(adjacent multifunctionality). The large share of multifunctionality
in the other four cases is explained by a diverse set of features:

Monreale, Southill, the Kwekerij, Valentano, Laarberg and Hemau.
With adjacent multifunctionality, however, land otherwise available
for electricity generation is used for other functions. This latter type
of multifunctionality therefore reduces the overall land use energy
intensity of the solar landscape (Scognamiglio, 2016).

Assessment of multifunctionality
The number of functions and the land surface allocated to
multifunctionality are useful indicators to compare SPP on
multifunctionality, yet they do not assess functions. Assessment
of ecosystem functions and services needs to provide insight in

Using these indicators, most of the cases in this study will be
outperformed by SPP that are optimized for electricity generation.
These assessments and their associated indicators will need to be
supplemented by other indicators that capture multifunctionality.
Temporality
Temporality in the cases was addressed in 8 out of 11 cases by
attention for landscape elements and patterns present in the host
landscape, active management during operation and maintenance
stage and landscape plans for the decommissioning stage.

Elements were often vegetation, such as hedgerows or trees, but
also former military bunkers were preserved (Hemau). In two
cases (Gänsdorf and Midden-Groningen) existing parcellation was
explicitly considered to maintain landscape character during the
operation and maintenance stage.

changing demands by local stakeholders resulted in the addition
of a vegetable garden in a later stage. On the contrary, other
cases indicate a lack of active management and appeared not to
be resilient to changing circumstances. In Monreale for example,
the olive grove adjacent to the solar system is currently in a poor
state. This olive grove was supposed to be used for local olive oil
production, but it seems it was not well embedded in the local

Reflections on emergent properties across frontrunner solar
landscapes
Although most cases pay attention to visibility, multifunctionality
and temporality, the spatial arrangement of each case illustrates
varying degrees of integration between solar infrastructure and
landscape features. In the Kwekerij, these are entwined to a degree
that the case is neither just a solar power plant nor just a public

to allow visitors to walk between the arrays, height of the arrays
has been adjusted to address visibility concerns of neighboring
residents. In Gänsdorf however, solar infrastructure and landscape
features are strictly separated: additional functions are not found
within, but next to the PV patches.
Whether landscape features are sustained beyond the
decommissioning of the solar infrastructure depends on the type
of the features. Features enhancing landscape character (e.g.
Southwick) or features able to provide a function independent
of solar infrastructure in the future (e.g. Kwekerij) are likely to be
sustained. In Midden-Groningen, on the contrary, some of the
landscape features are unfamiliar to the host landscape and their
existence will be less certain when the SPP is decommissioned.

First, although the cases altogether present a portfolio of measures

all cases. Alternative array orientation may support maintaining
existing landscape patterns and, simultaneously, reducing peak
load on the electricity grid. Another example is the presence of

assessments, multi-criteria decision analysis and other methods

example, assessment of enhancing visibility (e.g. through dedicated

property exclusively. Yet, other properties related to visual impact,

propose a typology that consists of four dimensions: energy,

main types, mixed-production, nature inclusive, landscape inclusive,
and their combinations. This typology adds to the existing energy
landscape vocabulary, provides direction to and ingredients for
(local) decision-making on solar energy landscapes. In doing so,
the research supports the development of energy landscapes
that contribute to global renewable energy targets with increasing
attention to societal considerations.

to increase while SPP become a major player to meet renewable
energy targets.
Societal considerations regarding SPPs, as with any other energy
infrastructure, are commonly discussed during the planning
and design process amongst stakeholders (Picchi et al., 2019).
Currently, societal considerations are often used to distinguish
between suitable and unsuitable sites for SPP development. Bridge
(2018) refers to this siting as a strategy of territorial dierentiation:

In this paper we therefore turn our attention to a strategy where
societal considerations change the nature of the SPP itself (Bridge
et al., 2013). Stakeholder values and preferences have started to
give rise to SPPs with multiple purposes, instead of only electricity
production (Oudes & Stremke, 2021). These multi-purpose SPPs
produce renewable electricity, but at the same time include

individual types of SPP in detail without considering other types
or has presented a typology of land use combinations, with little
attention to spatial form. Existing literature lacks insights in the
interaction between societal considerations and the spatial form
of SPPs. Such insights, however, can support local participatory
planning and design processes as well as evaluation and decision-
making for SPPs.

asked to characterize their SPP by distributing 100 points across the

In addition to the case informants, experts were interviewed
with the purpose to test the typology. We selected 17 experts
from an active community of professionals and academics in
the Netherlands that is engaged with the spatial development of
SPPs. Selected experts were expected to have an overview of the
development of multi-purpose SPPs. We were able to interview 14
of these experts (response rate 83%), with backgrounds in solar
industry (4), design & consultancy (4), academia (3), government (2)
and NGO (1). The interviews were conducted and recorded using
Microsoft Teams. The semi-structured interview protocol was tested
once in advance and allowed experts to use an SPP case well known
to them to engage with the typology. We used cognitive interviewing
to understand how the experts interpreted and related the spatial
properties of their case to the typology (Willis & Artino, 2013). By
discussing the expert case, we received feedback on the dimensions,
the types and the spatial properties. Of the 14 experts, 10 discussed
a case that was not part of the initial case study, introducing new
case evidence to the development of the typology. The interview

of the spatial properties and types.
The transcribed interviews were analyzed to identify patterns
across the expert feedback. The feedback on the properties was
used to complement and specify the case analysis framework.
Feedback on the dimensions and types was used to inform our
understanding of the typology. Major comments by multiple experts
were incorporated in the typology, minor comments by one or two
experts were addressed by improving the description of the types.

spatial form of an SPP can be examined and discussed.
The energy dimension forms the basis of a multi-purpose SPP and
– in relationship to spatial form – is expressed by energy density.
Energy density is indicated by, for example, yearly production per
hectare (in MWh/ha/y), power capacity per hectare (in MWp/ha) or
spatial footprint of the system (land area occupation ratio, LAOR)

Often, energy density of multi-purpose SPPs is lower compared to
SPPs that focus only on maximizing electricity production. Attention

With the energy dimension as basis, an SPP addresses societal
considerations by a predominant focus on either the economic,
nature or landscape dimension. Such a focus leads to three main
types: nature inclusive, landscape inclusive and mixed production

Fig. 5.2. Four dimensions of solar power plants: energy, economic, nature

and is expressed by energy density, in this gure by the land area occupation
ratio (LAOR) (Oudes & Stremke, 2021; Scognamiglio, 2016). The economic
dimension comprises economic activities in addition to electricity production.
The nature dimension consists of spatial properties related to nature. For the
landscape dimension the same logics apply.

Based upon the case study, the expert interviews and the responses
from the case informants, attention to the economic, nature and

and the intensity or scale of the properties. An SPP with many spatial

considerations, preferences or opportunities that stakeholders have
included in the spatial form. At the same time, a consideration can
also materialize by including only one or two large-scale features. For
example, in Southill Solar (United Kingdom), the local sustainability
cooperative decided to dedicate more than half of the project
area to biodiversity improvements. Furthermore, case informants
used terms such as ‘marginal’ and ‘small-scale’ to indicate certain

project as a whole. In addition, seven experts mentioned the aspect
of scale, an ecologist for example argued “more space [for nature]
is always better from a nature perspective”. This feedback makes
clear that attention to a certain dimension is not only the presence
of an certain feature, but also its scale in comparison to the other
dimensions. To convey the typology in a systematic and transparent
way, the examples in the remainder of the results section only show
the number of properties related to the dimensions.
In addition to the main types, the cases often expressed a mix of
dimensions. These combination types are nature and landscape
inclusive, nature inclusive mixed production and landscape inclusive
mixed production. Nature and landscape inclusive SPP followed
directly from the case study, while the other two combinations were
stressed by several experts during the interviews and supported by
projects still under construction. In the following, we will describe
the three main types, mixed-production (5.3.3), nature inclusive
(5.3.4), landscape inclusive (5.3.5) and the types that combine
multiple dimensions (5.3.6).

functions. Based upon the case study, we found three major land
use functions in addition to solar energy generation: agriculture,
other renewable energy technologies and other commercial
activities related to the SPP or the site. In SPPs combined with
agriculture, often termed ‘agrivoltaics’, PV panels are located
between or above some form of agriculture, either crop production
or livestock. In a fruit farm in Babberich (the Netherlands), the solar
developer placed semi-transparent PV panels above the fruit trees

synergy between the two productive functions as key arguments for
this spatial variation (or sub-type) of MP SPP. In other variations of
MP SPPs, multiple (renewable) energy technologies are co-located,
for instance wind turbines and biomass facilities. Co-location of
multiple renewable energy technologies may include a shared use
of grid capacity, but it is also used for place branding: Eggebek, a
former military airport in Germany, presents itself as an ‘energy and
technology park’ and includes other commercial activities related to
renewable energy technologies. In this case, the SPP is combined
with wind energy testing and research, a biogas facility and other
companies related to renewable energy.

relatively porous PV patch with ecological features mainly between

the right conditions for the (created or retained) ecological features
is related to accessibility: adjusting the permeability of the perimeter
(usually a fence) to deny or allow access to certain species, depending
on the ecological targets and potentially limiting access for humans
when sensitive species are targeted. Experts stressed that proper
management of SPPs is needed to achieve the set ecological targets
and sustain them through time.

Indicatively, three sets of variations in spatial form emerge. First,
similar to nature inclusive SPPs, landscape inclusive SPPs reserve
space for functions other than electricity production beneath
or between PV panels (array or patch multifunctionality, e.g.
walking paths between PV panels) or next to PV panels (adjacent
multifunctionality, e.g. a lookout next to PV panels).
Second, variations in active and non-active engagement with
landscape users. Li SPP that actively engage landscape users include
recreational or educational features. This may vary from providing
a visual overview of the SPP from constructed vantage points,
to providing public access to the SPP for leisure and community

Contrastingly, for Li SPP that not actively engage landscape users,
stakeholders decided to keep the SPP (partly) away from the perception
of landscape users. Such SPPs use for example local landscape
elements or low PV arrays to reduce visibility of the PV panels.
The third set of variations involves the kind of interventions done
in the existing landscape. Some cases focus on preserving existing
landscape features, other cases on restoring landscape features
that were present in the past and again others on transforming the
site using new landscape features.

Combinations of economic, nature and landscape dimension
In addition to SPPs with a single focus on the economic, nature or

leads to a combination of multiple dimensions. Departing from the

A few cases showed attention to all dimensions. Monreale (Italy)
was developed as a demonstration project and includes an olive
grove for local olive oil production (economic dimension), an
ecological corridor (nature dimension) and aligns with existing
landscape patterns (landscape dimension). In addition, one of the
experts discussed a case, under construction at the time of the
interview, that combined electricity production with nuts and berry
production (economic dimension), ecological improvements of the
waterways (nature dimension) recovery of historical landscape
elements (landscape dimension). Moreover, the agricultural
activities are performed by a social farm that employs people whom

Neither the case study nor the expert interviews, revealed evidence

multiple experts emphasized the potential and necessity of this

Discussion
This paper presented an emergent typology of SPPs, of solar power
plants that consist of an alternative spatial form following inclusion
of societal considerations in addition to electricity production.
The typology consists of four dimensions: energy, economic,

contributed to the vocabulary of solar energy landscapes that may
support such a process.
Reflection on methods and data
The typology of SPPs was built upon cases from four European
countries (Germany, The Netherlands, United Kingdom and Italy).
Although this selection provided national and regional variety in for
example landscape type, policy and legal regulations, other contexts
may bring forth additional insights on the spatial form of SPPs.
Furthermore, the experts that were interviewed were all Dutch and
part of a professional and academic community that also includes

the experts discussed the typology primarily from their daily ‘reality’
in the Dutch context. However, we believe that the Netherlands, with
its high population density and scarcity of space, is representative
of other urban delta’s in the Global North. The second limitation
is that some of the experts were aware of previous work of the
authors, which may have led to social desirability bias. To counter
this response bias, not uncommon in such studies, experts were

and support their arguments with evidence from the expert case.
The case informants scored the attention for landscape lower
compared to the outcomes of the case study. This lower attention
for landscape of case informants can be explained by the fact
that case informants primarily mentioned tangible landscape
features added to the case, for example picnic benches, lookouts
and charging points for electric bicycles. Less tangible properties,
such as alignment of PV patch to landscape patterns, were only
mentioned by one case informant.

Energy landscapes are the product of a societal process, involving
negotiations between stakeholders. The typology presented in this
paper gives direction to and provides ingredients for (local) decision-
making on solar energy landscapes. Such evidence based decision
making supports a social process that results in energy landscapes
that contribute to global renewable energy targets with increasing
attention to societal considerations.

The visual impact can be dealt with by reducing visibility, but also
by enhancing visibility in combination with recreational facilities.
Ecological, recreational, agricultural and water management features
can become part of solar landscapes, addressing considerations
of land use competition. These features may increase the needed
amount of land for renewable energy provision. Considerations with
regard to the end-of-life stage of solar technology are addressed in
a few cases only, by creating landscape features that enhance the
use of the site after decommissioning.

Furthermore, I will discuss the limitations of the research design of

landscape knowledge and stakeholder preferences (chapter 2).
Physical landscape characteristics such as relief, land use and
building types are used to identify the potential for solar energy,
wind energy, heat-cold storage, water power and biomass. These
physical landscape characteristics are generally available in maps
and databases and prone to expert evaluation. Furthermore,
landscape knowledge of local stakeholders provides a detailed view

physical landscape characteristics exclusively (Wolsink, 2017).
Knowledge on landscape is also key to the local design of energy
landscapes (chapter 4). For solar landscapes, critical elements of
the local design are existing landscape patterns and elements, solar
infrastructure and their interactions. Knowledge consists of both
the physical landscape (e.g. matching size and shape of PV patches
to existing plots) as well as the way landscape users interpret and
experience that landscape (e.g. adjusting the height of PV panels to
decrease the visibility for nearby inhabitants).

Tenet 2: Active use of time
In a landscape inclusive energy transition, policy makers,
designers, developers and landscape users actively use time in the
development of energy landscapes.
Existing research on landscape change regards time as a rather
passive factor: over time, preferences of local stakeholders may
change in favor of the landscape change, pointing to the adaptability

thesis show the potential to engage with time as an active factor in
the development of energy landscapes.
First, as stressed in the previous tenet, local designs of energy
landscape may incorporate historic patterns and elements,
responding to past versions of landscapes (chapter 4). Although this
may come at the cost of a lower energy density, preserving patterns
and elements connects to previous generations and sustains place
identity (Le Dû-Blayo, 2011).
Second, engagement of local stakeholders with energy landscapes
is often diminished once renewable energy technology is
operational in the present (Moore & Hackett, 2016). Multi-purpose
energy landscapes encompass other-than-energy functions that
stakeholders can engage with during the operation stage, such as a
fruit orchard that needs maintenance or a recreational walking path
(chapter 4). In addition to their active contribution to site selection
and design stages, landscape users can be given the opportunity to
propose changes to the energy landscape during operation stage as
expectations change or new ideas emerge (Schulz & Skinner, 2022).

and legislation to be resilient to changing circumstances. Changing
ownership or economic circumstances for example, may threaten
the continuity of these functions through time (chapter 5).

Finally, the end-of-life of energy technology in a certain project
marks a window of opportunity for landscape users to adapt that
energy landscape to the new situation.
Tenet 3: Energy landscapes respond to the diversity of society
In a landscape inclusive energy transition, the diversity of societal
interests, values and concerns together shape a large variety of
multi-purpose renewable energy landscapes.

The typology of multi-purpose solar power plants (chapter 5)
provides the directions to take into account both the physical
landscape and how it is interpreted and experienced. Insight
in a large variety of multi-purpose energy landscapes supports
communities to shape their energy landscape their way (Wolsink,
2017). Although the typology may help stakeholders to converge
to a shared solution, it may also help to identify where stakeholder

Balanced attention for the past, present and future of landscape
Proponents of a comprehensive understanding of landscape
balance attention for the past, present and future of landscapes.
Besides attention to the present, attention to the past and the
future in landscape projects may be one of the remedies towards
climax thinking: the belief that our current landscape is the
intended endpoint for our given context (Sherren, 2021). The

comprehensive understanding of landscape, landscapes become a
medium to facilitate engagement with stakeholders, from design to
implementation (Nassauer, 2012). Engagement of stakeholders with
energy landscapes may in turn lead to energy citizenship (Ryghaug,

Southill Solar (see section 1.1) provides a promising perspective on
material participation involving a large number of landscape users.
On the societal level, this thesis showed that a single driver for

multiple other societal challenges. A comprehensive understanding

Focus on solar power plants
This thesis has argued for a landscape inclusive energy transition,
for a substantial part based upon solar power plant case evidence.
Research on the interaction between solar power plants and
landscape has been limited, while their number has increased
over the past decade (Comello et al., 2018). The cases examined
in this thesis showed that considerations from local stakeholders
and society at large shape multi-purpose energy landscapes

2017). In chapter 5, one informant per case (e.g. the designer,
initiator or developer) was involved to test their interpretation of
the dimensions of the solar power plant typology. Future research
involving a larger sample of landscape users can provide more
detailed insights on the applicability of the typology in planning
and design practice and understanding how societal considerations
shape physical energy landscapes.
The comparative case analysis was limited to the physical landscape
and did not study the interaction between considerations and
physical landscape during the planning and design process.
Other researchers of my chair group currently employ action
research to examine these interactions in participatory processes
on solar landscapes.

Planners and designers need to be immersed in a landscape by
studying the physical landscape and devising ways to understand

A balanced attention for the past, present and future of landscape

Policy makers therefore need to consider potential future states of
energy landscapes and use backcasting to identify the interventions
and policies needed in the present (Windemer & Cowell, 2021).
Members of cultural heritage committees should not only focus on
preserving existing characteristics but also how a renewable energy
project can improve landscape characteristics.

Contemporary assessment methods implicitly or explicitly consider
renewable energy technology as an intervention with inherent
negative externalities. With a comprehensive understanding of
landscape, methods need to assess the energy landscape as
complete landscape rather than the impacts of a technology on a
landscape. Assessment methods of energy landscapes therefore
need to include societal considerations, notions of past, present and
future, and capture positive impacts in addition to negative impacts.

energy landscapes are created (to mitigate climate change) but
also how and what kind of energy landscapes are created. This

and maintains natural processes. Knowledge of existing landscape
characteristics, such as linear vegetation patterns or microrelief
provide the conditions for ecological improvements. This thesis
pointed to restoring lost landscape features or introducing new
landscape features that improve ecological conditions. While
interventions on the site may improve local biodiversity (Randle-
Boggis et al., 2020) considering the larger landscape context of
the project area provides additional opportunities. Considering
these higher scales, especially with linear landscape features and
ecological stepping stones, can improve species movement and
increase ecological robustness (Blaydes et al., 2021). Moreover, a
regional approach to the siting of solar power plants could result
in new ecological networks with solar power plants as hotspots
(Semeraro et al., 2018). Frontrunner regions planning multiple
of such solar power plants could serve to research both the
opportunities and challenges of a so-called ‘eco-energy network’.
From a cross-sectoral perspective, a landscape inclusive energy
transition supports synergies with other societal challenges on
various spatial scales. Recent research, for example, suggests to
deliberately site solar power plants with honeybee facilities near
fruit orchards to improve pollination, creating synergy between
ecological and economic objectives (Armstrong, Brown, Davies,
Whyatt, & Potts, 2021). Planning for a landscape inclusive energy
transition connects food security, local economy and renewable

conventional and thus limited understanding of landscape in energy
transition arenas has led to a situation where landscape has become
a perceived obstacle to the transition. This thesis has revealed that
a more comprehensive understanding can move ‘landscape’ from
problem to solution space and, eventually, become a catalyst for
the 21st century energy transition. Understanding landscape as co-
construction of natural processes, human activities and diverse
experiences provides promising avenues for environmental
planners and designers to establish solid grounds with both natural
and social sciences in pursuit of an inclusive energy transition.

population density, the implications of landscape transformation
caused by the energy transition may therefore be severe.
Accordingly, landscape is a key arena for the energy transition where
the interests, values and concerns of local stakeholders and society
at large meet. This arena encompasses diverse stakeholders: local
inhabitants, energy cooperatives, NGOs, industry, grid operators,
policy makers, decision makers and researchers.
Many of these agents disregard or have a limited view on the
concept of ‘landscape’.
‘Landscape’ is often disregarded in setting energy targets, selecting
sites and designing renewable energy projects. Instead, the focus

Previous research primarily focused on energy technologies
instead of energy landscapes: technology and landscape are
commonly considered to be separate entities. As early as 1958,
British landscape architect Sylvia Crowe advocated in The Power of
Landscape an alternative approach: to start designing ‘complete
landscapes’, instead of mitigating inertia between technology
and landscape.
Studies focusing on the ‘complete landscapes’ for energy transition
are still rare. While other scholars too advocate this, they have so

by enhancing visibility in combination with recreational facilities.
Ecological, recreational, agricultural and water management
features can become part of solar landscapes, directly mitigating
land use competition. Considerations with regard to the end-of-

by creating landscape features that enhance the use of the site

Energietransitie en landschap worden vaak gezien als een ‘zero-
sum game’: voortgang voor het eerste staat gelijk aan (beleefde)
verliezen voor het laatste. Deze beleefde verliezen ontstaan door
de transformatie van vertrouwde en gekoesterde landschappen,
gedreven door de noodzaak om hernieuwbare energie doelen
te behalen en klimaatverandering tegen te gaan. Landschappen

met een hoge bevolkingsdichtheid kunnen de gevolgen van
landschapstransformatie veroorzaakt door de energietransitie
groot zijn. Om die reden is het landschap de ‘arena’ voor de
energietransitie, waar de belangen, waarden en zorgen van lokale
stakeholders en de maatschappij als geheel bij elkaar komen.
Deze arena omvat verschillende stakeholders: lokale inwoners,
energie coöperaties, ngo’s (niet-gouvernementele organisaties),
bedrijfsleven en industrie, netbeheerders, beleidsmakers,
bestuurders en onderzoekers.
Veel van deze stakeholders hebben nauwelijks aandacht voor
landschap of hebben een beperkte blik op het concept ‘landschap’.
‘Landschap’ wordt vaak genegeerd bij het bepalen van energietransitie
doelen, locatiekeuzes en ontwerpen aan hernieuwbare energie-
projecten. In plaats daarvan ligt de focus op de technologische

als achtergrond of decor. Het gevolg hiervan is dat beoordeling
van de landschappelijke kwaliteit van projectvoorstellen wordt
beperkt tot de (on)zichtbaarheid van energie infrastructuur. De
visuele aspecten van landschap worden hierdoor teveel benadrukt,
waardoor projectvoorstellen worden afgewezen of maatregelen
worden genomen om zichtbaarheid te verminderen, zonder daarbij
244 | Landscape-inclusive energy transition
rekening te houden met karakteristieken van het landschap. Verder
wordt ‘landschap’ ook vaak gezien als een stabiel fenomeen. Het
gevolg hiervan is dat de huidige staat van het landschap niet kritisch
bevraagd wordt en als referentiepunt geldt voor elke mogelijke
verandering. Als het huidige landschap teveel benadrukt wordt in de
energietransitie leidt dat tot het verschuiven van de opgave naar de
gemeenschappen die elders leven of toekomstige gemeenschappen.
Dit negeren van het landschap en het beperkte, conventionele begrip

heeft negatieve gevolgen voor de kwaliteit van onze landschappen.
Om deze reden vragen onderzoekers en de maatschappij als
geheel om aandacht voor een energietransitie waarin ‘landschap’
een prominentere plek krijgt in de processen om energiedoelen
te bepalen, hernieuwbare energieprojecten te ontwerpen en
energiebeleid te ontwikkelen. Steeds meer fysieke landschappen
ontstaan die niet alleen maar zijn geoptimaliseerd volgens
technische en economische parameters, maar die fysieke
kenmerken van landschappen en maatschappelijke overwegingen
weerspiegelen. Voorbeelden zijn multifunctionele ‘solar power
plants’ en ‘solar landscapes’. Multifunctionele ‘solar power plants’
hebben andere doelen naast elektriciteitsproductie door middel
van zonnepanelen, zoals voedselproductie, het verbeteren van
ecologische kwaliteit of het faciliteren van recreatieve activiteiten.
Kenmerkend voor het concept ‘solar landscapes’ zijn het aanpassen
van patronen van zonnepanelen en het meenemen van agrarische
of recreatieve functies in samenhang met de karakteristieken
van het bestaande landschap, of het maken van nieuwe,
onderscheidende patronen.
Eerder onderzoek heeft zich voornamelijk gericht op energie
technologieën in plaats van energielandschappen: technologie en
landschap worden gewoonlijk gezien alsof ze los van elkaar staan.
Al in 1958 pleitte de Britse landschapsarchitect Sylvia Crowe
voor een andere benadering: begin te ontwerpen aan ‘complete
landschappen’, in plaats van het ontbreken van de samenhang
tussen techniek en landschap te verdoezelen.

Studies die zich richten op deze ‘complete landschappen’ in de
energietransitie zijn nog zeldzaam. Hoewel andere onderzoekers
wel op het belang hiervan wijzen, blijven ze vooralsnog theoretisch

energiedoelen, ontwerpen aan hernieuwbare energieprojecten
en ontwikkelen van energiebeleid. Het ontbreken van deze kennis
geeft aan dat er noodzaak is voor wat in deze PhD thesis wordt
omschreven als een landschaps-inclusieve energietransitie: een
energietransitie die een veelomvattender begrip van landschap
omarmt, meer dan een ‘decor’ of een ‘stabiel’ fenomeen. Ondanks
de voordelen van een landschaps-inclusieve energietransitie is
het nog onduidelijk of en hoe landschap in plaats van dat het als
obstakel wordt ervaren, juist een katalysator kan zijn voor de
21e-eeuwse energietransitie.
Daarom is het doel van deze thesis om de basisprincipes van
een landschaps-inclusieve energietransitie te onderscheiden, om
de energietransitie vooruit te helpen alsook maatschappelijke
overwegingen rondom landschap mee te nemen. De volgende
vragen zijn gebruikt als leidraad in het onderzoek, elke bestudeerd
in een individuele onderzoeksmodule:
1. Hoe kunnen energietransitie doelen worden bepaald die

Als eerste is een methodologisch raamwerk ontwikkeld om
onderzoekers te helpen energiepotenties te analyseren en
energietransitie doelen te bepalen (hoofdstuk 2). In het raamwerk
wordt gebruik gemaakt van lokale kennis van landschap,
landschapskarakteristieken en voorkeuren van stakeholders om
een landschaps-inclusieve energietransitie op de regionale schaal
te bevorderen. Door ‘landschap’ vroeg in het energietransitie
proces mee te nemen, kunnen maatschappelijke overwegingen de
keuze voor technologie en locatie ondersteunen, een tijdspad voor
de uitvoering informeren en uiteindelijk energietransitie doelen
bepalen. Deze inzichten kunnen beleidsmakers en bestuurders
helpen om bestaand beleid aan te passen of nieuw beleid te maken,
om locaties binnen de regio te vinden en om criteria voor het lokale
ontwerp van hernieuwbare energie landschappen te bepalen.
Om de tweede onderzoeksvraag te beantwoorden is de literatuur
van drie grootschalige landschapstransformaties systematisch
geanalyseerd, om te begrijpen hoe met functionele-, belevings- en
toekomst aspecten van landschappelijke kwaliteit kan worden
omgegaan in de energietransitie (hoofdstuk 3). Er is ruim bewijs
dat landschapstransformaties voordelen voor alle drie de aspecten
van landschappelijke kwaliteit kunnen hebben. Met betrekking tot
functionele aspecten gaat het om multifunctionele landschappen die
ontstaan als overheden bestaande, lokale opgaves of toekomstige
vragen meenemen in de transformatie. Hoe stakeholders hun
landschap beleven moet worden begrepen door ontwerpers en
overheden voordat ze oprecht betrokken kunnen worden bij het
proces van landschapstransformatie. Toekomstaspecten worden
meegenomen in landschapstransformatieprojecten door in het
ontwerp te anticiperen op toekomstige vragen van stakeholders of
de maatschappij als geheel.
Een vergelijkende analyse van ‘solar landscapes’ is gebruikt
om de derde onderzoeksvraag te beantwoorden (hoofdstuk
4). Visuele, functionele en temporele eigenschappen van de
Samenvatting | 247
S
onderzochte cases tonen aan hoe maatschappelijke overwegingen
leiden tot verschillende fysieke landschappen, vergeleken
met monofunctionele ‘solar power plants’ die alleen maar
geoptimaliseerd zijn voor elektriciteitsproductie. Visuele impact kan
worden aangepakt door zichtbaarheid te verminderen, maar ook
door zichtbaarheid juist te verbeteren in combinatie met recreatieve
faciliteiten. Ecologische, recreatieve, agrarische en waterbeherende
elementen kunnen onderdeel worden van ‘solar landscapes’, en zo
direct landgebruikscompetitie te verlichten. Overwegingen die gaan
over de fase wanneer zonnepanelen het einde van hun levenscyclus
hebben bereikt, worden maar in enkele cases geadresseerd. Dit
gebeurt door landschapselementen toe te voegen die het gebruik
van de plek verbeteren wanneer het energiesysteem is ontmanteld.
Tot slot, de vierde onderzoeksvraag is beantwoord door middel
van een typologie van multifunctionele solar power plants. De
typologie bestaat uit de dimensies economie, natuur en landschap
die illustreren hoe verschillende maatschappelijke overwegingen
leiden tot verschillende typen solar power plants (hoofdstuk 5).
Het ‘gemengde-productie’ type combineert elektriciteitsproductie
met andere economische functies zoals voedselproductie. Het
‘natuur-inclusieve’ type combineert elektriciteitsproductie met

‘landschaps-inclusieve’ type combineert elektriciteitsproductie met
het verbeteren van het fysieke landschap en/of het gebruik en de

van de energietransitie ondersteunt en tegelijkertijd helpt om
maatschappelijke overwegingen rondom landschap hierin mee te
nemen. Deze tweezijdige benadering is hier geformuleerd als een
landschaps-inclusieve energietransitie, waarvoor ik vijf basisprincipes
248 | Landscape-inclusive energy transition
heb onderscheiden. In een landschaps-inclusieve energietransitie:

basis voor locatiekeuzes en ontwerp, (2) gebruiken beleidsmakers,
ontwerpers, ontwikkelaars en landschapsgebruikers tijd op een
actieve manier in de ontwikkeling van energielandschappen, (3)
vormt de diversiteit van maatschappelijke belangen, waarden en
zorgen gezamenlijk een variatie aan multifunctionele hernieuwbare
energielandschappen, (4) worden andere grote uitdagingen van
de 21e eeuw, zoals voedselveiligheid en biodiversiteit, gekoppeld

landschap meegenomen en landschapswaarden gecoördineerd van
de lokale tot de internationale schaal en vice versa, door overheden
alsook andere publieke en private stakeholders die betrokken zijn
bij de governance van landschappen.
Deze vijf basisprincipes suggereren dat een meer veelomvattend
begrip van het concept ‘landschap’ nodig is in de energietransitie
en andere transformerende opgaves. Voorstanders van zo’n
veelomvattend begrip van landschap (1) omarmen ‘landschap’
zowel als fysiek landschap (object) en hoe mensen dat landschap
interpreteren en beleven (subject), (2) houden aandacht voor
verleden, heden en toekomst van energielandschappen in
evenwicht, (3) maken betrokkenheid van lokale stakeholders en de
maatschappij als geheel mogelijk tijdens planning en ontwerp en (4)
geven vorm aan landschappen op meerdere schaalniveaus.
Een veelomvattender begrip kan ‘landschap’ van probleem naar
oplossing doen verschuiven om eens een katalysator te worden voor
de 21e-eeuwse energietransitie. ‘Landschap’ zien als co-constructie
van natuurlijke processen, menselijke activiteiten en diverse
ervaringen vormt een veelbelovende gezamenlijke basis voor
ruimtelijke planners en ontwerpers om samen met natuur- en sociale
wetenschappen te streven naar een inclusieve energietransitie.

to point me to ‘energy landscapes’ during my studies, although at
that time I hardly understood the concept and few scholars had
published about this topic. During my master’s thesis, I had multiple
conversations with the late professors Meto Vroom and Klaas
Kerkstra about ‘technology’ in landscapes, a topic they both dealt
with in their research. These conversations broadened my thinking
that was later deepened in my collaborations with Jhon van Veelen,
whom dedicated a large part of his career to both theory and
practice of designing the electricity grid in the Dutch landscape.
These encounters paved the way for working with energy landscapes
in collaboration with my promotor Sven Stremke, to whom I am

The need to advance energy transition has arisen from the global challenge of climate change. Shifts to renewable energy sources, such as solar energy, are crucial for reducing carbon emissions and mitigating climate change. The use of agrivoltaics-the combination of food and renewable energy production with photovoltaic technology is gaining scientific attention. Agrivoltaics is a type of multifunctional energy landscape and thus reduces land use conflicts between energy and food production. However, while agrivoltaics has begun to proliferate at a global scale, the associated landscape changes have so far received little attention. This knowledge gap is critical, as there is clear evidence that landscape change often contributes to low levels of acceptance of solar power installations. To address this gap, this study examines landscape changes brought by agrivoltaic installations in the Netherlands. Four representative built cases were examined making use of key landscape change indicators extracted from the literature and fieldwork. The study revealed varying degrees of landscape change across the examined cases. Changes in the agricultural landscape pattern and openness emerged as prominent landscape changes. Changes in crop type and in historical linear landscape structures-often associated with the implementation of conventional solar power plants-were not identified. Policy attention to the siting and design of agrivoltaic systems in the landscape is needed to positively influence social acceptance of this relatively novel solution and thereby advance energy transition.
... The discourse yet needs to adopt where and how questions. 'Landscape' can interconnect these questions and in that sense provides a solid starting point for a more inclusive debate on energy transition (OUDES 2022, PICCHI et al. 2023. To exemplify the power of landscape for energy transition and beyond, we will now focus on one of the frequently voiced dilemmas: central versus decentral decisions making and implementation. ...

Climate crisis demands decarbonization of our energy supplies. The upscaling of renewable energy is accelerating around the world. Most renewable energy projects fail to realize values other than reducing greenhouse gas emissions and societal support is eroding. Many critics appropriate 'landscape' to oppose, postpone or reallocate climate action. The objective of this paper is to highlight another, often overlooked power of landscape: The power of landscape to enable learning, reflecting, and resolving critical questions regarding climate action. Landscapes, we sustain, deserve ever more attention in the pursuit of timely climate action. We illustrate that the transition to renewables provides the very foundations for new cultural landscapes. This paper draws from a recently published book-The Power of Landscape-which presents our research and design at the Amsterdam Academy of Architecture , complemented by essays from renown architects, geographers, sociologists, and historians.
... Recent environmental engineering enterprises have further led to the invention of floating solar technology (floatovoltaics) for generating renewable energy that inherently improves the ability of natural systems to preserve the natural ecosystem (Allen and Prinsloo, 2018;Essak and Ghosh, 2022;Wood Mackenzie, 2019). The technology contributes to the land-use intensity discussion, a narrative that presents a significant drawback in most modern electrical power production schemes (Havrysh et al., 2022;Oudes, 2022), especially because new brownfield energy developments often involve the sacrifice of biomass and crop production in food-producing regions to deliver marginal residual life cycle climate change benefits (Lovering et al., 2021). Considerations around improving the understanding of sustainability in landscape-inclusive energy transformations sparked an interest in exploring the catalytic benefits of farm land-surface reclamation and irrigation water preservation of floatovoltaics. ...

Floating Solar PV (FSPV, FPV or floatovoltaics) is an emerging decentralised energy concept in climate-smart agriculture that is quickly becoming a trend in water-rich regions with high land costs, land scarcity and underutilised water areas. FPV technology has excellent environmental compatibility properties, assists in shrinking a farm's carbon footprint, aids farms in decarbonisation towards a net-zero emissions goal, while supporting sustainable energy development towards better carbon taxation and green energy certification in sustainable farming ventures. Amidst a rapidly growing international interest in floating PV and agrivoltaic solutions as climate-solver technologies, current knowledge gaps around its environmental and energy-water-land resource impact uncertainties are the main barriers to floatovoltaic installation deployments. Current FPV performance and impact assessment methodologies still need to overcome critical knowledge gaps constraining fully functional evidence-based scientific assessments as a mandatory requirement to regulatory project permissions prescribed by law. This doctoral dissertation investigates the characterisation and quantification of floating photovoltaic power performance benefits, environmental impact offsets and economic sustainability profiles in a theoretical PV performance model-driven water-energy-land-food resource features. With FPV as natural resource preservation energy technology touching issues along the interplaying water-energy-land-food nexus dimensions (WELF-nexus), a robust validation of the technology's co-benefits and suggested impacts on the nexus of local energy-water-food (EWF) system was lacking. Rethinking environmental sustainability in the FPV context, this research investigation uncovers the root cause of current predictive analytical problems in floating PV characterisation as relating to critical knowledge gaps and modelling challenges in four dimensions: (a) reductionist thinking philosophy as an overwhelming modelling approach engaged by most current PV system assessment models; (b) low-priority role of the natural environmental system and micro-habitat in the integrated systems modelling characterisation of floating PV as a system of systems; (c) inadequate modelling consideration given the water-energy-land nexus system resources and linkages in a unidirectional open-loop linear assessment framework; and (d) modelling framework does not sufficiently cater for systemic interactions in the topological and ontological structures among the PV ecosystem components. Aiming to find a holistic systems thinking solution, the fourth industrial revolution offers information technology principles that enable subject-matter expert knowledge integration into the virtualization of intelligent energy production models using digital twin technology. As operational research paradigms for floating PV modelling, 4IR in digital twinning enables the study to define a new integrated theoretical framework for sustainability evaluation. Towards simulation analysis, this pluralistic-type systemic intervention can account for the extended range of resource-use-efficiencies and impact-effect-positives of floating PV technology in a computer-aided analysis-by-synthesis technique. While comparing the performances of FPV and GPV systems, this study makes a case for the systematisation of sustainability knowledge in the technogenic assessment for floating PV installations through the co-simulation modelling of a novel integrated technical energy-environmental-economic scientific sustainability assessment framework concept. This institutionalised sustainability framework mechanism drives the computer program logic and architecture in a computer synthesis methodology, to assess the integrative technological, economic and natural environmental system attributes in a pluralistic system dynamical way. The approach is further novel in that it covers both short-term and long-term perspectives in a cascaded closed-loop feedback system, with inter-domain feedback memory in a real-time computer synthesis methodology ensuring causal framework ontology modelling. The proposed sustainability definition and systemic framework policy for geospatial sustainability assessment offer a complex appraisal method and modelling technique that supports project decision-making in broad-spectrum environmental, economic and technical contexts that transcends the conventional technically biased scientific evaluation inherited from ground-mounted photovoltaics. The proposed theoretical reference framework and modelling technique offer multidimensional sustainability indicator dimensions, thus addressing critical decision-making domain elements focussed on by impact assessment practitioners, investment stakeholders and subject experts. The scientific investigation and results confer valuable insights into the value-laden sustainability qualities of FPV in pre-qualifying project-assessment experiments for future planned floating solar projects. The theoretical modelling, simulation and characterisation of floatovoltaic technology offer a data collection toolset for duly required scientific evidence of sustainability traits of the technology in support of the adoption, regularisation and licensing of floating photovoltaic renewable energy system installations. The research advances fresh philosophical ideas with novel theoretical principles that may have far-reaching international implications for developing floatovoltaic, agrivoltaic and ground-mounted PV performance models worldwide. ~ https://hdl.handle.net/10500/30091

Globally, hydropower developers are increasingly expected to share benefits with people living in project-affected areas. Nevertheless, hydropower benefit-sharing has not found sufficiently widespread application, and the concept is not yet widely understood. The present paper aims to make the following contributions: First, we clarify the commonalities and differences between benefit-sharing, compensation and related concepts, which refer to processes in which developers transfer resources to project-affected people. We suggest that benefit-sharing can be understood as a 'sustainability intervention', i.e. the focus is on making an additional and positive long-term development impact, beyond replacing or marginally improving on lost assets. Further, we propose that benefit-sharing is defined by the transfer of resources and services that are 1) substantively different from those serving as compensation for lost assets; 2) determined via participatory processes with project-affected people and 3) delivered in the later stages of the timeline from dam planning to operation. Second, we explore some governance challenges on the pathway towards 'good' benefit-sharing, highlighting: (i) that effective participation by project-affected people requires capacity building over time, involving a gradual transfer of control over spending decisions; and (ii) that the appropriate institutional setup for benefit-sharing may be dependent on the existing capacity of governments in the dam-hosting location. Legally mandated benefit-sharing mechanisms to raise funds may be more appropriate in the context of high existing state capacity, whereas developer-led mechanisms will be required where the existing capacity is low. In practice, a mix of multiple institutional arrangements and benefit-sharing mechanisms is possible and desirable.

Austria aims to meet 100% of its electricity demand from domestic renewable sources, such as wind energy. Apart from the benefit of reducing CO2 emissions and, potentially, system cost, wind power is also associated with negative impacts at the local level, particularly its interference with landscape aesthetics. Some of these negative impacts might be avoided by using alternative renewable energy technologies. To better understand the trade-offs involved, we quantify the opportunity cost of wind power versus its best feasible alternative, which is solar photovoltaics in Austria. Methodologically, our analysis relies on the power system model medea, a technology-rich, partial-equilibrium model of the Austro-German electricity and district heating markets. Our findings suggest that the cost of undisturbed landscapes is considerable, even more so when solar PV is mainly realised on rooftops. Under a wide range of assumptions, the opportunity cost of wind power is high enough to allow for significant compensation of the ones affected by local, negative wind turbine externalities.

A transition toward decentralized and land-intensive renewable energy production systems is one among many factors re-shaping rural areas, leading to reimaginations and contestations. Especially in the Global North, the rural narrative now includes not just rural ‘production’ but also the ‘consumption’ of rural amenity and experience. Previous research into public attitudes toward renewable energy correlates the former with positive attitudes to renewable energy, and the latter with negative attitudes toward renewable energy. Territorial structures, such as official land-use plans, reflect dominant discourses and narratives that shape ongoing rural transformation. The purpose of this work is to understand the extent to which, if at all, those correlations at the individual level between landscape conceptualizations and sentiment toward renewable energy are manifest in territorial structures. In what ways are energy transitions present in rural land-use plans and planning systems? Is there a relationship between how rural landscapes are conceptualized and how energy transitions are framed and addressed, in land-use planning systems? These questions are answered through a structured content and discourse analysis of 10 land-use plans of rural municipalities in southern Ontario; an agriculturally intensive region that hosts much of Ontario’s large-scale renewable energy systems. Correlations observed between landscape conceptualizations and sentiment toward renewable energy observed are not strongly reflected in land-use plans. Land-use plans in this region are not positioned to manage the place-based opportunities and impacts associated with renewable energy development. The research reveals an opportunity for rural land-use planning systems to more explicitly incorporate energy transitions in their evolving discourses, identities and development trajectories.

The Social Sciences and Humanities (SSH) have a key role to play in understanding which factors and policies would motivate, encourage and enable different actors to adopt a wide range of sustainable energy behaviours and support the required system changes and policies. The SSH can provide critical insights into how consumers could be empowered to consistently engage in sustainable energy behaviour, support and adopt new technologies, and support policies and changes in energy systems. Furthermore, they can increase our understanding of how organisations such as private and public institutions, and groups and associations of people can play a key role in the sustainable energy transition. We identify key questions to be addressed that have been identified by the Platform for Energy Research in the Socio-economic Nexus (PERSON, see person.eu), including SSH scholars who have been studying energy issues for many years. We identify three main research themes. The first research theme involves understanding which factors encourage different actors to engage in sustainable energy behaviour. The second research theme focuses on understanding which interventions can be effective in encouraging sustainable energy behaviour of different actors, and which factors enhance their effects. The third research theme concerns understanding which factors affect public and policy support for energy policy and changes in energy systems, and how important public concerns can best be addressed as to reduce or prevent resistance.

As an answer to the increasing demand for photovoltaics as a key element in the energy transition strategy of many countries—which entails land use issues, as well as concerns regarding landscape transformation, biodiversity, ecosystems and human well-being—new approaches and market segments have emerged that consider integrated perspectives. Among these, agrivoltaics is emerging as very promising for allowing benefits in the food–energy (and water) nexus. Demonstrative projects are developing worldwide, and experience with varied design solutions suitable for the scale up to commercial scale is being gathered based primarily on efficiency considerations; nevertheless, it is unquestionable that with the increase in the size, from the demonstration to the commercial scale, attention has to be paid to ecological impacts associated to specific design choices, and namely to those related to landscape transformation issues. This study reviews and analyzes the technological and spatial design options that have become available to date implementing a rigorous, comprehensive analysis based on the most updated knowledge in the field, and proposes a thorough methodology based on design and performance parameters that enable us to define the main attributes of the system from a trans-disciplinary perspective.

Solar and wind energy are expected to play a key role in creating a climate-neutral Europe by 2050 and decarbonizing energy production in general, albeit requiring significant deployment. This presupposes that the population accepts such energy sources, thus necessitates understanding how people perceive energy systems. Unlike the abundant literature about wind energy, social acceptance of solar energy has received less attention, especially concerning large solar installations. Opinion polls indicate that solar energy enjoys a high level of socio-political acceptance and is preferred to other renewables, although it is unclear whether this acceptance persists as the technology is deployed on a large scale. This paper helps close this gap by describing the results of a representative survey (n = 601) conducted using a between-subject design to examine how attitudes of the public towards solar energy vary based on the size of installations, how the latter compare to attitudes towards wind energy, and what the role of affect is in the former. Results reveal that the stronger preference for solar power decreases to a similar level as that for wind energy when comparing installation of similar sizes, highlighting that solar energy installations may not easily be scaled up. The study also shows that affect plays an important role in forming people’s attitudes towards wind and solar, especially concerning large-scale installations. This underlines the need for policymakers and project developers, who aim to deploy renewables on a large scale, to attend to the affective component of decision-making.

Habitat for pollinators is declining worldwide, threatening the health of both wild and agricultural ecosystems. Photovoltaic solar energy installation is booming, frequently near agricultural lands, where the land underneath ground-mounted photovoltaic panels is traditionally unused. Some solar developers and agriculturalists in the United States are filling the solar understory with habitat for pollinating insects in efforts to maximize land-use efficiency in agricultural lands. However, the impact of the solar panel canopy on the understory pollinator-plant community is unknown. Here we investigated the effects of solar arrays on plant composition, bloom timing and foraging behavior of pollinators from June to September (after peak bloom) in full shade plots and partial shade plots under solar panels as well as in full sun plots (controls) outside of the solar panels. We found that floral abundance increased and bloom timing was delayed in the partial shade plots, which has the potential to benefit late-season foragers in water-limited ecosystems. Pollinator abundance, diversity, and richness were similar in full sun and partial shade plots, both greater than in full shade. Pollinator-flower visitation rates did not differ among treatments at this scale. This demonstrates that pollinators will use habitat under solar arrays, despite variations in community structure across shade gradients. We anticipate that these findings will inform local farmers and solar developers who manage solar understories, as well as agriculture and pollinator health advocates as they seek land for pollinator habitat restoration in target areas.

The extent to which the impacts of renewable energy development might be reversible is an important dimension of debates about environmental acceptability, magnified in significance by the sector's rapid expansion and the inexorable ageing of facilities. However, despite frequent claims that the impacts of renewable energy are reversible, the complex realities of impact (ir)reversibility have attracted minimal systematic research. This paper addresses this gap with the first review of the research literature on impact (ir)reversibility, focused on onshore wind, and makes a number of contributions. Firstly, it shows that determining whether impacts are reversible or not inevitably entails selective, value-laden judgements about what matters and why. Secondly, a problem with much of the existing literature on (ir)reversibility issues is its abstract and hypothetical nature, detached from actual end-of-life decisions about renewable energy facilities, and their relationship with sites and landscapes. These insights are used to generate a conceptual framework for investigating impact (ir)reversibility-emphasising the benchmark, value basis, object of focus, allocation of responsibility, and regulatory mechanisms and the ways that long-term, end-of-life impacts are governed. The value of this framework is demonstrated through three empirical vignettes from the UK, and used to generate an agenda for future research.

Literature concerned with Natura 2000 highlights that conflicts emerged when local communities felt the implementation of the policy was unfair. In the paper, we extend those arguments and say that the contested nature of Natura 2000 conflicts is best understood through a framework of environmental justice that embraces the importance of empowering residents and communities in Natura 2000 processes. We draw from Nancy Fraser’s critical approach that organizes justice issues within distribution, recognition and representation domains simultaneously. It enables us to look at the Natura 2000 conservation conflicts from a critical standpoint of local communities. With it, we conceptualize the role of resident empowerment to compliment examinations of environmental policy conflicts. To re-construct the case of Natura 2000 conservation conflicts through the lens of pluralistic environmental justice perspective, we revisit processes in which a sense of (in)justice about Natura 2000 policy nourished conservation conflicts in Poland.
