The government is trying to encourage the use of renewable energy, one of which is from waste to energy power plant. Efforts to accelerate the development of the plant are carried out through Presidential Regulation Number 35 of 2018. However, only one plant has been operating commercially since May 6th, 2021. This study aims to describe the development, the obstacles, and whether the plant is a solution to meet electricity needs or environmental problems. Through qualitative research, we found that the plant in Surabaya has been operating commercially; the plants in Surakarta and DKI Jakarta are in the construction stage; the plants in Palembang and Tangerang are in the stage of confirming the developer, and the rest are still on auction stage, Pre- Feasibility Study, Outline Business Case, or Final Business Case. The high tipping fee, limited local government budget, overestimation of potential for waste as electricity, limited competent human resources, the high selling price of the plant electricity, and no bankable guarantee for investment are obstacles to the plant development. The thermal plant is an instant solution for cities with above 1.000 ton/day waste and limited land for landfills. In the future, there should be regulatory support through the Renewable Energy Bill to overcome the obstacles. In addition, there should be a careful calculation of the energy potential of waste, a minimum budget allocation of 2–3% for waste management and preparing capable human resources, providing adequate waste collection and transportation infrastructure, and educating the public on sorting waste. AbstrakPemerintah berupaya mendorong pemanfaatan energi terbarukan, salah satunya dengan membangun Pembangkit Listrik Tenaga Sampah (PLTSa). Upaya mempercepat pembangunan PLTSa dilakukan melalui Peraturan Presiden Nomor 35 Tahun 2018. Namun, hingga 6 Mei 2021 hanya satu PLTSa telah beroperasi secara komersial. Penelitian ini bertujuan mendeskripsikan perkembangan pembangunan PLTSa, kendala-kendala dan permasalahan pengembangannya, dan apakah PLTSa solusi pemenuhan kebutuhan listrik atau mengatasi masalah lingkungan. Melalui penelitian kualitatif, diketahui 1 PLTSa sudah beroperasi secara komersial (di Surabaya), 2 PLTSa dalam tahap konstruksi (di Surakarta dan DKI Jakarta), 2 PLTSa dalam tahap sudah ada pengembang (di Palembang dan Tangerang), dan sisanya masih dalam tahap lelang, Pre-Feasibility Study, Outline Business Case, atau Final Business Case. Lambatnya pembangunan PLTSa terjadi karena tingginya tipping fee, anggaran pemerintah daerah terbatas, over estimasi potensi listrik dari sampah, keterbatasan sumber daya manusia yang kapabel, tingginya harga jual listrik PLTSa, tidak adanya insentif bagi pengembang, dan tidak adanya jaminan bankable untuk investasi. PLTSa termal merupakan solusi instan mengatasi permasalahan lingkungan untuk kota dengan produksi sampah di atas 1.000 ton/hari dan keterbatasan lahan untuk TPA. Untuk itu, perlu ada dukungan regulasi melalui RUU EBT mengenai harga jual listrik PLTSa yang bersaing, insentif bagi pengembang PLTSa, dan jaminan bankable untuk investasi PLTSa. Selain itu, perlu ada perhitungan secara cermat potensi energi dari sampah, alokasi APBD minimal 2–3% untuk pengelolaan sampah, dan menyiapkan sumber daya manusia yang kapabel, menyediakan sarana prasarana pengumpulan dan pengangkutan sampah yang memadai, dan mengedukasi masyarakat untuk memilah sampah.

The idea of achieving energy security and lowering the dependence on the global hydrocarbon market is at the top of the agenda in many countries. Most of them consider switching from traditional energy sources to renewable ones as one of the ways to reduce fuel import. This concept absolutely conforms to one of the UN Sustainable Development Goals (Goal no. 7, “Affordable and Clean Energy”). In May 2019, the Government of Uzbekistan Republic adopted the law on the Use of Renewable Energy Sources (RES). By 2030, Uzbekistan is going to increase the share of RES in the total structure of electricity generation up to 25 % (currently it is at 10 %), by building solar and wind farms with a total installed capacity of 5,000 MW and 3,000 MW, respectively. The energy-deficient Bostanliq district of the Tashkent region has become one of the places of interest, where transport infrastructure, recreation services, and renewable energy will be developed. The purpose of this study was a multivariate analysis, considering the meteorological, ecological, and socio-economic characteristics of the Bostanliq district, leading to the selection of the optimal location for the wind farm. The assessment map based on the results of this analysis made it possible to identify areas that are most suitable for the location of wind power plants. The assessment method, that was used in this work, is also applicable to other regions of the world.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

Turkey wants to become the world’s 10th largest economy in the 100th anniversary of the foundation of the republic of Turkey. In order to achieve this goal, there are many breakthroughs in the political, economic and in energy fields. Turkey’s installed power capacity was 85000 MW in 2017 but installed power of 125.000MW is targeted to achieve the objective of 2023 targets. The government is aiming to increase the total production of renewable energy share by 30% in 2023, while foreseeing the increase in capacity due to nuclear and fossil fuel consumption. Targets for different technologies are 34000 MW hydroelectric, 20000 MW wind energy, 5000 MW solar energy (photovoltaic and condensed solar energy), 1000 MW geothermal energy and 1000 MW biomass. Capacity utilization in hydroelectricity is 62%, wind power is 14%, and geothermal power is 33%. The total installed capacity of Biogas, Biomass, Waste Heat and Pyrolytic Oil Power Plants is 530 MW. Theoretical total power capacity of the solar energy for Turkey as 300 TWh/year and reached 45% of the 2023 target in 2017 in the last three years. However, it is estimated that the targets of 2023 in solar energy can be exceeded. Government offers attractive incentive packages for renewable and other energy sector to achieve 2023 goals. In order to encourage domestic production, a total of 2000 MW wind and solar energy installation bid was carried out in 2017. This contract is expected to make Turkey as energy hub both in terms of installation and technology. In this study, Turkey’s renewable energy potential, and energy strategies and breakthroughs for this were investigated and discussed.

This paper investigates current and planned investments in new power plants in Bosnia and Herzegovina and impact of these investments on the energy sector, CO2 emission and internationally committed targets for electricity from renewable sources up to year 2020. Bosnia and Herzegovina possesses strong renewable energy potential, in particular hydro and biomass. However, the majority of energy production is conducted in outdated power plants and based on fossil fuels, resulting in environment pollution. New major investments The Stanari Thermal plant (300 MW) and the investment in Block 7 (450 MW) at the Thermal Plant Tuzla are again focused on fossil fuels. The power sector is also highly dependent on the hydrology as 54% of current capacities are based on large hydro power. In order to investigate how the energy system of Bosnia and Herzegovina will be affected by these investments and hydrology, the EnergyPLAN model was used. Based on the foreseen demand for year 2020 several power plants construction and hydrology scenarios have been modelled to cover a range of possibilities that may occur. This includes export orientation of Stanari plant, impact of wet, dry and average year, delayed construction of Tuzla Block 7, constrained construction of hydro power plants, and retirement of thermal units. It can be concluded that energy system can be significantly affected by delayed investments but in order to comply with renewables targets Bosnia and Herzegovina will need to explore the power production from other renewable energy sources as well.

Installed Capacity

In Turkey, current energy generations are not sufficient for the existing energy needs and besides, energy demand is expected to increase by 4–6 percent annually until 2023. Therefore, the government aims to increase the ratio of renewable energy resources (RES) in total installed capacity to 30 percent by 2023. By this date, total energy investments are expected to be approximately $110 billion. Turkey is the fastest growing energy market among the OECD countries. Therefore, Turkey is an attractive market for energy companies and investors. At this stage, site selection and deciding appropriate RES are the most important feasibility parameters for investment. In this study, “Site Selection in Turkey” issue for RES (solar, wind, hydroelectric, geothermal, biomass) is evaluated by the ELECTRE which is one of the Multi Criteria Decision Making (MCDM) methods. In addition, the reasons for choosing this method are explained according to the literature. The study emphasizes the importance of energy generation from renewable and sustainable sources and is concerned with improving the position of the country. The Turkish government offers many purchasing guarantees and high incentives, especially in the renewable energy sector. As a result of the analysis, the most suitable energy sources are presented according to the geography and energy potential of the regions. The study aims to inform energy firms and everyone related with RES about Turkey’s RES opportunities.

Development of renewable energy power plant represents a strategic way to increase electrification ratio and to reduce CO2 emission. One of renewable energy potential resources in Indonesia is solar power since the country is located in the equator line. In 2014, there are 8,170 kWp community based solar power plant that has been built by the government in the rural area. However, advantages of community based solar power plant will depend on its sustainability. This study examines the sustainability of community based solar power plant based on an interview with local government. It also determines the potential of community based solar power plant reduces CO2 emission at the research location. The interview was conducted with Authorized Environmental Agency. The results show that sustainability of solar power plant in the research area is considered to be good. It is also known that CO2 emission reduction in research location during its lifetime is 316,302 kg. It is believed that this successful example can provide policy recommendation for government to develop a more solar power plant in another rural area.

Algeria has enormous renewable energy potential. However, fossil fuels remain the main electricity generation source, and the country is the third largest CO2 emitter in Africa. Algeria is also particularly vulnerable to climate change. Therefore, a set of actions related to energy, forests, industry and waste sectors have been programmed, over the period 2015–2030, and the government action program has given priority to promote renewable energy. In this sense, Algeria is committed to significantly promote investment in renewable energy, during the period 2020–2030. Thus by 2030, renewable electricity production capacity will achieve 22,000 MW, representing 27% of total electricity generation. This paper analyzes the electricity generation measures implemented in Algeria to reach the required energy mix, the legislative framework, financial aid, the feed-in tariff system, the tax incentives, and the tender and auctions undertaken. The analyses reveal that, although the electricity price premium policy has not been revoked, the newly enacted tender scheme is designed to become the standard procedure for launching renewable energy projects in Algeria in the coming years.

Ethiopia has a vast renewable energy potential in the context of hydro, wind, solar, and geothermal energies. The unsustainable use of biomass coupled with drought has caused a paradigm shift towards wind, geothermal, and solar energies. There have been significant strides by the Government of Ethiopia to actualize these potentials in the context of developing massive projects in these aforementioned areas with the private business sector in the goal of jettisoning the industrial base of Ethiopia in conjunction with increasing the installed power capacity from 4,300 MW to 17,346 MW by 2020. The major challenge still lies in assessing the comprehensive renewable energy resource potential of Ethiopia including the lack of local content development in the context of establishing an industrial base. There have been notable initiatives by the Government of Ethiopia to adhere to the Paris Climate Accord in conjunction with the Green Growth framework and Sustainability Development Goals. However, the top down approach of grand targets to the various regions is not the pragmatic approach to solving the Achilles heel of energy poverty. A more plausible approach is from the bottom up, whereby energy frameworks and policies are generated by conducting a needs assessment of a specified region. The appropriate technology concept needs to be reflected in the innovation aspects of renewable energy technologies. There has to be a framework of translating invention to innovation by actualizing the tripartite structure of Government, Academia, and Industry.
