The supply of electrical energy in Tarakan City, North Kalimantan, still relies on diesel power which uses a limited number of petroleum energy sources. There is a need for research related to renewable energy sources that have the potential to become alternative energy for the people of Tarakan City. Water is an energy source that has great potential to generate electricity. The energy source that should be taken into account is micro-hydro which can be used as a Micro-hydro Power Plant (PLTMH). A survey of micro-hydro sources in Tarakan City, precisely in the Karungan area, East Mamburungan Village, has been carried out with the direct measurement method of water discharge and the relationship with the power generated. The result shows the water source has a discharge 0.00034 m3/ s, the water velocity of 0.035 m/s and generates power only up to 1.1 watts. Based on the power obtained, the water source in this place cannot be used as a source of micro-hydro energy, but has the potential as a source of pico-hydro energy.

AbstrakEnergi surya (matahari) merupakan salah satu sumber energi terbarukan yang paling penting dan sangat berlimpah di Indonesia. Dengan potensinya yang sangat besar tersebut, energi surya diyakini menjadi sumber energi utama di masa depan. Eenergi surya di Indonesia sangatlah besar. Indonesia memiliki sekitar 4.8 KWh/m2 atau setara dengan 112.000 GWp energi surya. Sayangnya energi surya ini belum mendapatkan porsi yang semestinya di negara ini. Dari total potensi energi surya tersebut, Indonesia baru memanfaatkan sekitar 10 MWp. Hambatan yang masih sering terjadi pada penggunaan PLTS ini adalah pada tidak dapatnya diprediksi keacaan cuaca dalam waktu yang singkat, sehingga produksi energi listrik sulit dapat memenuhi target yang diharapkan, dan hal ini membuat ketidak nyamanan pengguna. Perlunya penelitian terhadap efisiensi modul solar panel, karena saat ini efisiensi yang dihasilkan modul solar panel masih sangat rendah, sehingga untuk mendapatkan 1 KWh energi listrik masih tergolong sangat mahal.Abstract Solar energy (sunlight) is one of the renewable energy sources the most important and very abundant in Indonesia. With such huge potential, solar energy is believed to be the main energy source in the future. Solar Eenergi in Indonesia is very large. Indonesia has around 4.8 KWh / m2 or equivalent to 112,000 GWp of solar energy. Unfortunately, solar energy has not received the proper portion of the country. Of the total solar energy potential, Indonesia has only utilized approximately 10 MWp. Barriers are still common in the use of solar power is at the inability to predict the weather keacaan in a short time, so the production of electrical energy is difficult to meet the expected targets, and this makes it an inconvenience for the user. The need for research on the efficiency of solar panel modules, because the current efficiency of the resulting solar panel module is still very low, so to get 1 kWh of electrical energy is still relatively very expensive.

Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

The article considers the legal basis for the formation and development of the country's energy sector, in particular, the issue of energy production from renewable sources, among which the leading place belongs to wind energy. The tendencies of the world energy market, which minimize the negative impact on the environment, as well as the tendencies of development of this branch in Ukraine are investigated. It was stated that for our country wind energy is one of the strategic directions of development of the sector of alternative energy sources, given the high dependence of the country on imported energy, primarily natural gas, and significant potential for wind power, taking into account the location, climate and terrain. However, unfortunately, the pace of development of wind energy in Ukraine still lags significantly behind European ones. It is noted that the legislative provision of the use of wind energy in Ukraine as a source of alternative energy is characterized primarily by the number of bylaws, general declarative legislation, as well as some inconsistencies in legal regulation. An analysis of current legislation and a number of regulations governing the development of the industry in general and wind energy in particular. A review of the norms that relate purely to the issues of the research area and their features and direction of legal regulation. In addition, it was stressed that Ukraine's accession to European initiatives, as well as borrowing international experience in this area should positively affect the energy balance and ensure the development of the sector, in particular, in the light of the need to create a full competitive environment in Ukraine's energy market; changes in heat generation by renewable energy sources and the full transformation of coal regions, which means the gradual closure of unprofitable enterprises with the parallel creation of alternative jobs in these regions.

The article examines topical problems of the role of international organizations in the direction of the development of alternative energy and strengthening of energy security in the world. Considerable attention is paid to the importance of the introduction and development of alternative energy in the context of ensuring environmental human rights and economic well-being. Analyzed the main international legal treaties regulating the reduction of greenhouse gas emissions into the atmosphere and the use of alternative renewable energy sources. The main international governmental and non-governmental organizations in the direction of ensuring environmental and energy security have been identified. Attention is drawn to the need to strengthen the role of these organizations by strengthening the functions of supervision and monitoring to increase the possibility of influencing states that do not comply with the provisions of signed and ratified international conventions. It is concluded that it is necessary to adjust the vector of development of instruments for the protection of environmental rights in the direction of its world globalization. The existing global concept for the development of alternative energy sources requires changes. Given that the environmental problem is universal and, although to one degree or another, it still affects every person, regardless of country or nationality, the obligation to protect the environment must be universal, fulfilled and enforced not only by the government bodies of sovereign states, but also international government organizations. It is noted that the programs and recommendations of international organizations are developed directly for individual states, taking into account their geographical and economic location when choosing the types and methods of developing alternative energy.

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria
