1. Introduction
Indonesia is a vast archipelagic country, that’s why the fulfillment of electricity supply and demand in remote areas,
outer islands, and border areas is an important issue that requires a special review in its completion [2][5]. People in
un-electrified areas tend to be isolated from economic developments, knowledge insights, and technology advances.
In 2008, an articles of Indonesia Government Electricity Association (PLN) states in point number 3 that the purpose
and business field is to provide electricity supply business for the public interest in sufficient quantity and quality as a
form of implementation the Government's duties in order to support the national development [23]. Electrification
ratio value showed increasing chart in Indonesia over the last five years (2010-2014). At the end of 2014 the ratio has
reached 81.70%, which is 74.41% for Indonesia outside Java and 86, 69% for the Java island [3]. In 2015 there are
still provinces in Indonesia with electrification ratio below 50%, Jambi (43.88%) and Papua (47.21%), whereas for
Jakarta the capital region of Indonesia and its surroundings has been reached 100%.
Nowadays, the condition of East Java's electricity supply in 2016 still has surplus around 2,600 MW (Mega Watt)
and the excess is channeled to West Java, Central Java, and Bali. Although in 2013 the electrification ratio of East
Java was still 79.21%, then increased to 83.14% in 2014, and by the end of 2015 has reached 86.67% [18]. The number
of new demand for electricity in 2014 of 605,832 households has decreased from the year 2013 which amounted to
657,536 households, but because of the electricity supply and demand that can’t be met, this caused the waiting list
surge from the previous 30,920 households in 2013 increased to 45,296 households by the end of 2014. However, the
amount of electricity surplus is still very possible to increase the supply for Situbondo area whose electrification ratio
is still 64.88% and also for Madura in particular. This program will support the achievement of 100% national
electrification ratio target in 2020 by the government.
For Madura region its self, from a total of 219,439 households, which has been electrified is only about 129,522.
The electrification ratio in 2014 reached only 59.02%, which increased to 60.55% by the end of 2015. But for the
archipelago region, the electrification ratio still has not touched 40%. Data from the Department of Energy of Human
Resources of East Java Province as December 2015 stated that the number of un-electrified villages in Madura spread
in 4 districts, namely 50 villages in Bangkalan Regency, 78 villages in Sampang Regency, 58 villages in Pamekasan
District, and 32 Village in Sumenep regency [21] [22] [24] [25]. Prior to the construction of the Suramadu bridge,
which connected Java Island and Madura, in 2010, the available of electricity supply in Madura was 80MW, increasing
to 200MW in 2012, and going to 260MW by the earlier 2016.
The majority of the un-electrified villages are on the North Coast of Madura (Pantura) and also some unreached
islands from the main electricity source. For the archipelago, five islands are powered by Diesel Power Plant (PLTD),
including Sapeken, Gili Genting, Mandangin which have been operating for 24 hours, while Kangean and Sapudi are
still operating for 12 hours only. Based on data at the PLN office in Pamekasan area that takes care whole electricity
operational in Madura, the uneven flow of electricity in the southern and northern regions is caused by the less
supportive road infrastructure. Powerful electricity is in the southern region of Madura because the transmission
networks are built in the south, ranging from Suramadu, Bangkalan, Blega, Sampang, Pamekasan and Sumenep. To
provide the services to the northern region, namely Ambunten, Waru, Ketapang and Tanjung Baru, PLN requires long
power lines for infrastructure revamping process. Madura topography becomes an investment constraint in building
electricity infrastructure because in one village has only about 10 houses, and the distance of the villages are far from
each other [11]. In addition to many villages located in the highlands and also some islands that are difficult to reach.
According to Solarex (1996), Indonesia as a tropical country has high solar energy potential with an average
radiation of 4.5 kWh2 / m2 / day - 5.0 kWh2 / m2 / day, which means for 1 Kw photovoltaic (PV) can produce 4 to 5
kWh of electrical energy in one day [7]. These, became an advantage solution for PLN to build up some photovoltaic
power plants in order to electrified the remote areas in Madura Island which far from the main power generation
sources. The independency of photovoltaic power plant by processing the solar potency into electricity is a new trend
in Indonesia to overcome the un-electrified islands [4].
From the observation of the situation, conditions and issues in electrical operational system in Indonesia, the
research questions are: (1). How is the fulfillment condition of the electricity demand in remote area Madura Island?
(2). What are the constraints and obstacles for electricity supply? (3). What kind of renewable power plant could be
invested in remote area and how many capacity is needed?

2. Methodology
Based on the problems that have been described previously, the purpose of this study is to identify the factors that
caused obstacles in electricity supply in Madura Island by developing a simulation for an effective, efficient and
reliable solutions in electrical operational systems. We used system dynamics method based on consideration that
system dynamics enable us to accommodate internal and external factors that have significant impact to electricity
demand and operational process, as well as the determination of the appropriate and targeted electrical operational
system. As the first step, we defined and identified the currently problems in electrical operational system to
understanding the whole system before make a new model which represented the real system. Ventana Simulation
tools figured out the predominant factors and variables in the simulation system.
Causal Loop Diagram (CLD) is a model development in representation the real system, and it was used to analyze
the electrical operational systems by determined all variables which interacts each other and also have impact to the
system [11]. Fig. 1 below shows the variables in electrical operational system and their relevancy in electricity deficit
supply in Madura island.

Otherwise, the development model should pass two step of validation process to determine whether it is acceptable
to represent the real system or not. The first validation test is a statistical comparison of the average (mean
comparison), and the second test is amplitude variation ratio (percentage of error variance) [1] [6].
The Payback Period (PP) calculation is considered to study the feasibility investment of photovoltaic power plant
as the solution for the deficit electricity supply which created an independent electricity system in remote area.

3. Result and Discussion
3.1. Electricity Demand Model for Madura
Historical data that were collected from PLN in 2011 to 2015 show an average that electrical power increased 7.5%
annually, which for households increase 6.4% on average, 13.9% in business, Industry (industry) 12.2%, public and
social (public and social) of 8.3% [23]. Fig. 2 is a base model for representing the electricity demand and its prediction,
that were discussed in our previous research [16].
Fig. 2. Base model for electricity demand in Madura.
3.2. Validity and Reliability
The electrical power requirement model developed in the simulation can be said to be valid and represent the
system if the calculation has been qualified for mean comparison (E1) and variance error (E2). Data in Table 1 below
present the electricity demand per customer category, where the results obtained is less than the maximum limit
requirement so that the development model in Fig. 2 was valid and reliable.

3.3. Scenario Model
The majority of PLN customers in Madura are household category whose electrical power about 450VA - 1300VA,
so the calculation of minimum electrical power requirement for photovoltaic power plant development planning is
still far from the standard 900VA that should be held for household electrical demand [7] [13]. In this research, the
value of electricity demand restricted only in Pamekasan Regency because it is where the main office of PLN that in-

charge to control the electrical operational system for whole Madura.
The development planning of photovoltaic power plant for five sub-districts (Waru, Palengaan, Batumarmar,
Pasean, and Pakong) that located in Pamekasan Regency will be divided into two types to adjust the geographical
condition of the un-electrified villages, namely:
Solar Home System (SHS) by using 50Watt peaks (WP) solar panels for villages located in the highlands,
Centralized Photovoltaics (Photovoltaic communal) by using 100Wp solar panels for coastal and lowland
Fig. 3 below was a scenario model to calculate the electricity demand for 58 remote villages in Pamekasan regency
by determining the current electricity supply for Madura island and the capacity of photovoltaic power plant capacity
which is categorized into 2 types solar panel according to the topography landscape.
Fig.3. Scenario model for fulfillment ratio the electricity demand in Madura
The total requirement for electricity supply in the five sub-districts in Pamekasan is 24,935 MW. These, will be
fulfilled by the development of new and renewable power plant with local resources like the Photovoltaic Power Plant
whose electrical supply capacity amount 25 MW.
3.4. Economics Aspect
The feasibility study of the economical aspect for the Photovoltaic Power Plant investment is calculated in detail
from the financial valuation of the cash flow of an investment. The Payback Period (PP) method is used to calculate
the amount of time it takes to return the money invested. Profit and cost analysis is needed in deciding whether a
project / activity is feasible or not realized. The depreciation value associated with the economic life in the Photovoltaic
Power Plant system is divided into two categories, namely: 25 years for solar panels, and 5 years for equipment
components (batteries, inverters, etc.). Therefore, there must be a replacement of components every 5 years to maintain
the continuity of power supply whose source of fund is burdened to the community and put into operational cost.
By using the formulation in [8, 9], the capital investment and cost to be borne in detail will be described in the
following calculations for 25MW needs for Photovoltaic Power Plant is:
Solar Panel = 25 MW x US$ 1.875.000 x Rp 13.500,- = Rp 632.812.500.000,-
Power Plant Component = 25% x Rp 632.812.500.000,- = Rp 158.203.125.000,-
Depreciation Component (per 5 year) = Rp 158.203.125.000,- / 5 = Rp 31.640.625.000,- /year

The feasibility study of the economical aspect for the Photovoltaic Power Plant investment is calculated in detail
from the financial valuation of the cash flow of an investment. The Payback Period (PP) method is used to calculate
the amount of time it takes to return the money invested. Profit and cost analysis is needed in deciding whether a
project / activity is feasible or not realized. The depreciation value associated with the economic life in the Photovoltaic
Power Plant system is divided into two categories, namely: 25 years for solar panels, and 5 years for equipment
components (batteries, inverters, etc.). Therefore, there must be a replacement of components every 5 years to maintain
the continuity of power supply whose source of fund is burdened to the community and put into operational cost.
By using the formulation in [8, 9], the capital investment and cost to be borne in detail will be described in the
following calculations for 25MW needs for Photovoltaic Power Plant is:
Solar Panel = 25 MW x US$ 1.875.000 x Rp 13.500,- = Rp 632.812.500.000,-
Power Plant Component = 25% x Rp 632.812.500.000,- = Rp 158.203.125.000,-
Depreciation Component (per 5 year) = Rp 158.203.125.000,- / 5 = Rp 31.640.625.000,- /year

period needed to invetsmen return is 70,63 year.
4. Conclusion
Building a new power plant source should be based on good planning as investment in the electricity industry is
demanded for long-term benefits. This should be the main consideration of PT. PLN in conducting an electricity
project. The amount of investment required will be one of the obstacles in determining the priority scale of
infrastructure development in a region. However, a smooth flow of operational funds can be used to support new
investment projects that reach areas in Madura that are still unable to enjoy electricity.
Basically the technical problems that become obstacles in the electrical operational system encountered in Madura
will also be found in other parts of Indonesia, as a vast and rich country of islands as well as small islands far from
the main power source. So in the future, serious and specific assessment of the potential of natural resources for new
and renewable energy that is owned by each remote, outer, and leading areas, in order to create an independent
electrical concept.

East Java has great potential in utilizing agricultural waste as a source of biomass energy to support the transition to New Renewable Energy (NRE). However, the development of biomass power plants faces challenges such as investment feasibility evaluation and biomass potential measurement. The East Java Government has set sustainable energy targets through Governor Regulations. This study developed a dynamic system-based simulation model to analyze factors influencing the utilization of agricultural waste as biomass energy. Verification results using Vensim PLE software show the model is valid with an error rate of E1 < 5% and E2 < 30%. In the Do-Nothing scenario, the electricity deficit could worsen in the future without increasing power plant capacity, especially from renewable energy. Conversely, the biomass power plant infrastructure development scenario shows that by 2024, the electricity deficit can be reduced from -7,599.47 GWh to -2,722.98 GWh. This trend continues in subsequent years, with the biomass scenario consistently decreasing the deficit and even generating a surplus in some years. Therefore, developing biomass-based power plants is a strategic step to reduce dependence on fossil fuels and enhance regional energy security in East Java.

In the last few decades, the Suwung landfill site has been used by Denpasar, Badung, Gianyar, and Tabanan, which are all part of the Sarbagita area. Using the system dynamics model method, the study aims to examine various alternative policy scenarios to maximize waste management at the source and determine their effect on waste carried to the Suwung landfill. Three scenarios are simulated: business as usual (BAU), implementation of the Regional strategy policy (RSP) for waste management, and optimization of the informal (INF) sector. According to the modeling results from 2020 to 2050, the four regions cannot entirely rely on the Suwung TPA's limited processing capability. Increasing the role of residents by maximizing their motivation and optimizing the informal roles in each region remains crucial. The simulation reveals that the RSP scenario is the best option when considering the amount of waste that must be managed, the need for integrated waste processing sites, and environmental emissions, despite requiring more waste processing facilities. The RSP scenario is carried out by raising awareness among residents to manage waste in their homes through the enhanced implementation of government policies. The model validation shows that the dynamic system can be used to investigate how different aspects should be considered when planning sustainable waste management.
... Residents in areas that have not been electrified tend to be isolated from economic growth, knowledge, and technological advances.

Renewable power plants and alternative power are the best options to meet the world's electricity needs considering the expensive and scarce of petroleum power which has remained the main option in the power generation system. Electric power is something of the main need used by humans. Nationally, the demand for electricity continues to increase to coincide with the rate of population growth, but the rate of demand for very fast power is not matched by the real creation of power zones. Currently, national energy is still focused on fossil energy, namely coal, petroleum, and natural gas. With the increasing use of energy, especially petroleum, until in the future the amount also continues to be limited, fossil energy reserves will decrease and will not be relied on to meet energy needs, because its non-renewable nature requires to quickly explore renewable energy sources. The results of the research tried at an average voltage of 5.12 Volts. As well as the average wind speed of = 4.88 m/s on the contrary, the average rotation speed of the generator is = 8.4 rpm

Conference Paper
Renewable energy is an important source to maintain the availability of energy for the future, due to the depletion of current energy sources based on oil and gas, coal, and other non-renewable energy sources. The energy emitted by the sun can be used as a form of renewable energy, namely solar energy. One of its implementations is to use a series of photovoltaic (PV) cells that can convert solar energy into electrical energy for everyday life. Indonesia is one of the countries located on the equator, which causes an overall temperature that is relatively higher than the world’s average temperature. This high temperature brings the high potential for Indonesia to cultivate solar radiation (solar energy) as a renewable energy source. The construction of solar power plants in Indonesia can help in the distribution of electrical power to meet the country’s power needs. In this study, the examiner will solve a problem in the use of energy in the surrounding environment, by building solar power plants in Indonesia. This research will conduct analysis based on simulations using RETScreen and PVSyst software. The result obtained from PVSyst is that in the selected location, around 42,500 units of Longi Solar monosilicone 415 Wp 34 V type LR4-72-HIBD 415 M Bifacial modules with 7 inverters installed on above 97,234 m2 modules area can export 23,877 MWh whereas using RETScreen, the cost needed to build the solar power plant is about $ 28,998,750 with 47,500 units of Longi Solar monosilicone type LR6-72PH-370W modules on 92,055 m2 modules area that can export 23,094 MWh.

... Renewable energy is a freely available, clean, environmentally friendly power source (Mevada et al., 2022;Suresh et al., 2020), and provides energy generation at a competitive cost (Ribó-Pérez et al., 2021). Renewable energy sources such as solar are abundant in Madura, but alone, each is unreliable and thus unsuitable for separate use (Quentara & Suryani, 2017). Thus, to resolve this issue, combining other renewable energy sources (e.g., biomass) has to be practiced to provide a reliable energy supply (Eteiba et al., 2018). ...

Madura Island, Indonesia, which is dominated by lowlands, is closer to the equator and has a warmer and drier climate than its nearest neighbour, Java Island. Despite its aridity, agriculture is among the primary economic activities of its inhabitants. Hence, renewable solar and biomass energy are available to be harvested. The techno-economic and environmental aspects of a grid-connected power system were analyzed using solar and biomass energy source data from two rural areas of Madura. Several configurations were simulated and optimized using HOMER software. A solar–biomass hybrid system was predicted to provide cost-effective power generation. Analysis of economic indicators (e.g., net present cost and cost of energy) suggested that these projects are financially feasible. Greenhouse gas emission predictions were more than 56% lower for the grid-connected solar-biomass hybrid system than grid-only supply. Solar–biomass hybrid systems can therefore serve as cost-effective modes of power generation for rural areas in Madura and are recommended.

This paper offers a system dynamics simulation-based approach to better understand the effects of solar photovoltaic diffusion. Specifically, the paper sheds light on how photovoltaic solar panels (PVSP) at end-of-life (EoL) might become an economic opportunity regarding their main components disposal and recovery. In order to do so, we base our study on the case of the five most significant countries in solar photovoltaic (PV) installed capacity in the world (i.e., China, Germany, Japan, United States of America, and India). Besides their relevance on PV diffusion, most countries still lack specific guidelines for the issue of PVSP EoL management. The goal of the work is to offer some tangible values to support the decision making processes, to guide the development of policies and regulations, and to reinforce the importance of scientific and technological improvement to achieve scalable recycling processes of the PVSP waste. Our simulation framework allows to estimate the potential market for PV deployment and to calculate the respective amount of PVSP at EoL, which could not be possible with other means due to increase in the average lifetime of the panels and improvements in recycling technology efficiency.

The foremost energy source originating from the sun, which is solar energy is widely utilized in solar technologies such as photovoltaic cells installed in energy plates, street lights, and water pumping. Meanwhile, the combination between solar radiations and nanotechnology is utilized in solar aircraft (SA). Therefore, this article investigated the working function of parabolic trough solar collector (PTSC) to analyze the performance of SA wings. The SA performance is reported due to the heat transfer analysis in the working fluid flows in PTSC, where the selected fluid is tangent hyperbolic hybrid nanofluid (THHNF). The THHNF is this article contains the blend of two nanoparticles (NP), including Copper (Cu) and Silica (SiO2), in the EG-Ethylene glycol viscous fluid. The heat transfer in the working fluid flows in the wings is discussed by considering the influencing factors, namely as variable thermal conductivity, thermal radiations, and porous media. In addition, entropy generation is also conducted for THHNF. The early set of mathematical formulation has been handled using a finite difference method. The distributions of velocity, temperature fields, shear stress, coefficient of surface drag, and Nusselt number are are depicted and tabulated: These results are restricted to the effect of controlling parameters. The main finding from this article is: The aircraft wings experience an enhancement in the heat transmission due to an amplification of thermal radiative flow and variant thermal conductivity. In comparison with conventional nanofluid, hybrid nanofluid shows better performance in heat transmission. The thermal efficacy of SiO2/Cu-EG over Cu-EG recorded a minimal level of 0.2%, and reached maximum percentage at 3.9%.

Solar panels are renewable energy which is very useful for agricultural needs to meet electricity needs, one of which is its application in agriculture, namely as a pump driver for hydroponic plants. Hydroponics is farming with an emphasis on meeting the nutritional needs of plants using water as a medium with a nutrient solution as fertilizer. In the hydroponic system the pump must be on continuously, for this reason the Automatic Transfer Switch (ATS) tool is used to substitute the electrical energy of the State Electricity Company (PLN) with the electrical energy of solar panels in the event of a power outage from the State Electricity Company (PLN) which aims to drain nutrient water. This research aims to apply solar panels to a hydroponic plant system and apply the Automatic Transfer Switch (ATS) tool as a substitute for the State Electric Company's (PLN) electrical energy and solar panels. This research was carried out on Jalan Polonia no.11 fresh water east, North Padang District, Padang City, West Sumatra in January – March 2024, with the initial stages (1) preparation, (2) solar panel assembly, (3) analysis of test results , (4) preparation of reports. The results of this research can determine the power output required by solar panels as a renewable energy source as well as the application of the Automatic Transfer Switch (ATS) in hydroponic plant cultivation.

Indonesia terletak di daerah katulistiwa sehingga memiliki intensitas penyinaran matahari yang baik sepanjang tahun. Kondisi penyinaran ini potensial untuk digunakan dalam pembangkitan listrik tenaga surya (PLTS). Pemanfaatan tenaga matahari untuk pembangkitan listrik sebenarnya sudah dilakukan sejak cukup lama namun aplikasinya masih terbatas pada sistem berdaya kecil atau yang lebih dikenal dengan solar home system (SHS). SHS ini biasanya merupakan bantuan pemerintah yang diberikan secara subsidi dan masyarakat pedesaan menggunakannya sebagai sarana penerangan di malam hari untuk mengganti lampu minyak tanah. Dalam konteks ini terlihat bahwa pendekatan yang digunakan bersifat top-down sehingga selama ini perkembangan SHS sangat tergantung pada program pemerintah dan sejauh ini kontribusi energi listrik surya nasional masih sangat kecil. Masyarakat perkotaan merupakan komponen yang cukup besar dalam komposisi populasi Indonesia. Sebenarnya kelompok masyarakat ini hampir semuanya berada dalam jangkauan jaringan listrik PLN namun demikian mereka memiliki karakteristik yang lebih baik dibandingkan dengan masyarakat pedesaan dalam pemanfaatan PLTS seperti daya beli, tingkat pendidikan, serta pemahaman tentang lingkungan dan penyelamatannya. Di samping itu, peranan energi listrik dalam kehidupan masyarakat urban sudah sangat melekat sehingga ketidaktersediaan energi tersebut akan berpengaruh langsung terhadap kehidupan mereka seperti produktifitas dan kenyamanan. Beberapa ciri positif yang dimiliki masyarakat urban ini bisa dijadikan penggerak pemasyarakatan PLTS perkotaan yang bersifat swakarsa dan swakelola. Melalui pendekatan berbasis pemberdayaan masyarakat kota ini diharapkan akan menjadi komponen penting dalam upaya peningkatan kapasitas terpasang PLTS nasional untuk mencapai target sekitar 5% energi listrik terbarukan pada tahun 2025 seperti ditetapkan dalam Kebijakan Energi Nasional. Salah satu prasyarat dalam perluasan pemanfaatan PLTS adalah ketersediaan peralatan dan komponen PLTS tersebut. Tulisan ini mencoba untuk meninjau ketersediaan sistem PLTS di Indonesia yang kapasitasnya sesuai dengan kebutuhan rumah tangga di perkotaan. Ketersediaan yang dimaksud meliputi data tentang kapasitas dan vendor dari komponen PLTS. Informasi tentang ini diharapkan dapat dijadikan sebagai salah satu acuan cepat untuk mengetahui perkembangan PLTS di Indonesia khususnya bagi masyarakat yang tertarik untuk memanfaatkan tenaga matahari sebagai sumber pembangkit listrik

This paper presents for the first time an integrated life cycle sustainability assessment of the electricity sector in Turkey, considering environmental, economic and social aspects. Twenty life cycle sustainability indicators (11 environmental, three economic and six social) are used to evaluate the current electricity options. Geothermal power is the best option for six environmental impacts but it has the highest capital costs. Small reservoir and run-of-river power has the lowest global warming potential while large reservoir is best for the depletion of elements and fossil resources, and acidification. It also has the lowest levelised costs, worker injuries and fatalities but provides the lowest life cycle employment opportunities. Gas power has the lowest capital costs but it provides the lowest direct employment and has the highest levelised costs and ozone layer depletion. Given these trade-offs, a multi-criteria decision analysis has been carried out to identify the most sustainable options assuming different stakeholder preferences. For all the preferences considered, hydropower is the most sustainable option for Turkey, followed by geothermal and wind electricity. This work demonstrates the importance for energy policy of an integrated life cycle sustainability assessment and how tensions between different aspects can be reconciled to identify win-win solutions.

Currently, 80% of conventional energy is used to fulfill general public's needs and industries. The depletion of oil and gas reserves and rapid growth in conventional energy consumption have continuously forced us to discover renewable energy sources, like solar, wind, biomass, and hydropower, to support economic development in the future. Solar energy travels at a speed of 186,000 miles per second. Only a small part of the radiant energy that the sun emits into space ever reaches the Earth, but that is more than enough to supply all our energy demand. Indonesia is a tropical country and located in the equator line, so it has an abundant potential of solar energy. Most of Indonesian area get enough intensity of solar radiation with the average daily radiation around 4 kWh/m 2 . Basically, the solar systems use solar collectors and concentrators for collecting, storing, and using solar radiation to be applied for the benefit of domestics, commercials, and industrials. Common applications for solar thermal energy used in industry are the SWHs, solar dryers, space heating, cooling systems and water desalination.

In this paper, we analyze the technical efficiency and CO 2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiency in the transformation of inputs into desirable (energy) and undesirable (CO 2 emissions) outputs, taking into account different fossil fuel generation technologies. We use a unique data set of coal-, lignite-, gas- and biomass-fired power plants from 2003 through 2010 that provides an unbalanced panel of 1459 observations; the results are also checked against a balanced panel with a smaller number of observations. Although we find intra-group differences within energy generation technology, natural gas fired power plants clearly have the highest efficiency. Furthermore, the analysis points to significant savings potentials for CO 2 and fuel-input, and derives policy conclusions for the ongoing electricity sector reformation.

Renewable energy based village grids (RVGs) are widely considered to be a sustainable solution for rural electrification in non-OECD countries. However, diffusion rates of RVGs are relatively low. We take the viewpoint that, as public resources are scarce, investments from the private sector are essential to scale-up the diffusion. While existing literature mostly focuses on engineering, development and techno-economic aspects, the private sector's perspective remains under-researched. As investment decisions by private investors are mainly based on the risk/return profile of potential projects we — based on literature reviews and field research — investigate the risk and the return aspects of RVGs in Indonesia, a country with one of the largest potentials for RVGs. We find that considering the potential of local, national and international revenue streams, the returns of RVGs can be positive. Regarding the risk aspect, we see that private investors could address many of the existing barriers through their business model. However, the findings also point to the need for government action in order to further improve the risk/return profile and thereby attract private investments for RVGs.

The Chinese economy is in a stage of energy transition: from low efficiency solid fuels to oil, gas, and electric power, from agriculture to urbanization and industrialization, from heavy industry to lighter and high tech industry, from low motorization to rapid growth of the motor vehicle population. Experts fear that continued rapid economic growth in China will translate into a massive need to expand imports of oil, coal, and gas. We build an econometric model of the Chinese energy economy based on the energy balance. We use that model to forecast Chinese energy consumption and imports to 2020. The study suggests that China will, indeed, require rapidly growing imports of oil, coal, and gas. This growth is not so sensitive to the rate of economic growth as to increases in motorization. It can be offset, but probably only in small part, by increasing domestic energy production or by improvements in the efficiency of use, particularly in the production of electric power.

Energy arguably plays a vital role in economic development. Hence many studies have attempted to test for causality between energy and economic growth; however, no consensus has emerged. This paper, therefore, tests for causality between energy and GDP using a consistent data set and methodology for over 100 countries. Causality from energy to GDP is found to be more prevalent in the developed OECD countries compared to the developing non-OECD countries; implying that a policy to reduce energy consumption aimed at reducing emissions is likely to have greater impact on the GDP of the developed rather than the developing world.
