In the past century, fossil fuels have dominated energy supply in Indonesia. However, concerns over emissions are likely to change the future energy supply. As people become more conscious of environmental issues, alternatives for energy are sought to reduce the environmental impacts. These include renewable energy (RE) sources such as solar photovoltaic (PV) systems. However, most RE sources like solar PV are not available continuously since they depend on weather conditions, in addition to geographical location. Bali has a stable and long sunny day with 12 hours of daylight throughout the year and an average insolation of 5.3 kWh/m2 per day. This study looks at the potential for on-grid solar PV to decarbonize energy in Bali. A site selection methodology using GIS is applied to measure solar PV potential. Firstly, the study investigates the boundaries related to environmental acceptability and economic objectives for land use in Bali. Secondly, the potential of solar energy is estimated by defining the suitable areas, given the technical assumptions of solar PV. Finally, the study extends the analysis to calculate the reduction in emissions when the calculated potential is installed. Some technical factors, such as tilting solar, and intermittency throughout the day, are outside the scope of this study. Based on this model, Bali has an annual electricity potential for 32-53 TWh from solar PV using amorphous thin-film silicon as the cheapest option. This potential amount to three times the electricity supply for the island in 2024 which is estimated at 10 TWh. Bali has an excessive potential to support its own electricity demand with renewables, however, some limitations exist with some trade-offs to realize the idea. These results aim to build a developmental vision of solar PV systems in Bali based on available land and the region’s irradiation.

The article analyses the role of renewable energy in the process of the development of the energy market of the East African Community (EAC) . The author underlines the necessity of finding solutions for such challenges as rising wood and charcoal prices, deforestation, lack of affordable and reliable electricity for a large number of consumers. The study reveals that nowadays the percentage of people with access to modern sources of energy is very low, varying from 7 % in Burundi to 36% in Kenya, although the EAC countries made significant progress in 2000s. Most people in rural areas rely on traditional biomass for cooking and heating, which leads to ecological and health problems. The author concludes that renewable energy development is considered by the Community as one of the prospective ways for providing energy to remote regions in view of abundant solar, wind and geothermal resources. Their strategy aims at the construction of micro and mini hydro stations, stand-alone solar PV systems and off-grids for rural population usage. The study shows that the investment in off-grid renewables has been steadily rising in recent times . Analyzing grid-connected power generation electricity, the author elicits that it is also based on renewable electricity, which accounts for 65% of the total amount. Kenya, with the highest installed capacity in this sector, is investing mainly in geothermal, solar and wind sources of energy, while the others are focusing on hydropower and solar. For the purpose of attracting private investment, the EAC partner states adopted different regulations, including Feed-in Tariff, zero-VAT and GET FIT Programme. The author assumes that renewable energy financing is one of the main challenges despite the support of different international financial institutions, such as the World Bank, UNIDO, AfDB and others. Nowadays energy efficiency measures are becoming important instruments for the EAC countries resulted in power savings. The other important trend is increasing cooperation among them due to their grid-connected power systems in the East African Power Pool. In this context, in November 2017, the EAC Partner States adopted Energy Security Policy Framework, in order to ensure the sustainable development of their energy sector.

Sunlight is energy that can be converted into electrical energy. One of the uses is by applying it to the roof ofthe building. The application in this building has restrictions such as the placement of the PV moduleshorizontally and vertically. In the study comparing the results of energy obtained from the PV system withhorizontal and vertical positions with a standard degree angle in the direction of azimuth sunlight. Positionusing the horizontal produces more energy and reaches a performance ratio of more than 80%.
