Energy efficiency investments are subject to various risks and uncertainties, which may affect involved actors’ profitability, and as such, there is a need for developing tools to support their decisions. So far, the developed methodological frameworks that aim at projecting the profitability and risk of such investments present a high technical co...

Households in the private rented sector (i.e., households renting properties at a market rate from a private landlord), and especially those of lower income, face far more energy poverty issues than the general population, meaning that they are often unable to afford socially and materially required levels of energy services. In this context, energ...

There are considerable differences in the pace and underlying motivations of the energy transition in the different geographical contexts across Europe. The European Union's commitment to climate neutrality by 2050 requires a better understanding of the energy transition in different contexts and scales to improve cooperation of involved actors. In...

Energy models are used to inform and support decisions within the transition to climate neutrality. In recent years, such models have been criticised for being overly techno-centred and ignoring environmental and social factors of the energy transition. Here, we explore and illustrate the impact of ignoring such factors by comparing model results t...

To achieve the European Union's target for climate neutrality by 2050 reduced energy demand will make the transition process faster and cheaper. The role of policies that support energy efficiency measures and demand-side management practices will be critical and to ensure that energy demand models are relevant to policymakers and other end-users,...
