The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

With each passing year, the problem of using alternative energy sources is gaining increasing attention, since the energy of the sun, water and wind, unlike hydrocarbons, belongs to practically inexhaustible resources. Besides this, alternative energy sources are relatively environmentally friendly, so any country is interested in using them. One of the factors affecting the increase of energy generation from alternative sources is the legal regulation of this area by the government. In many foreign countries a number of conceptual, doctrinal and program documents are adopted and implemented, which are dealing with the use of renewable energy sources. In order to stimulate the use of alternative energy sources, the governments of some countries create favorable conditions for attracting investment in the development of this sector, which, further, not only creates new jobs, but also has a generally positive effect on the economy.

Actuality of the problem. The article discusses the current level of use of alternative sources of electrical power in the world. The main areas of the global power development were determined, the statistical data of leading energy companies, analytical international organizations and financial institutions were analysed. For today, all civilized countries successfully switch to alternative energy sources: wind, solar energy, biofuels, etc. In addition, the use of solar energy is one of the most promising inexhaustible, renewable energy sources. The use of renewable energy sources replaces the traditional one, based on extractive technologies polluting the atmosphere with harmful emissions, and enhances the greenhouse effect, reduces the burden on the resource base and energy systems of countries and improves the environment. Sustainable development of the agricultural sector of the economy of Ukraine and, in particular, irrigated agriculture requires a reduction in energy dependence. In the structure of the cost of irrigation water, a significant share accounts for electrical power. That is why to increase the efficiency of irrigated agriculture, to ensure high and sustainable yields in the context of climate change, it is extremely important to reduce the cost of power consumption. The need to use alternative energy sources in the drainage complex of Ukraine as part of the implementation of the energy strategy of Ukraine, aimed at the transition to fficient use and consumption of energy resources is highlighted. The Institute of Water Problems and Land Reclamation deals with the investigations of measures and technologies to improve power efficiency to reduce the specific energy consumption for pumping water by pumping stations and to reduce the rate of power losses for water intake and water transportation by water supply paths. One of the effective measures to reduce power cost is the use of alternative energy sources, in particular solar energy. The economic potential of the measures for improving energy efficiency in irrigation systems wass estimated. Conclusions. The estimation showed that the use of modules of solar power plants installed above the surface of open irrigation canals will lead to lower energy costs in the face of a constant increase in tariffs, that is, it will help to increase the economic efficiency of irrigation, reduce the share of water resources in national energy consumption and have a positive environmental effect. The sale of surplus power to the energy system at “green” tariffs can significantly reduce the payback period for the modernization of the engineering infrastructure of irrigation systems.

The study in this chapter examined policy options for promoting solar PV diffusion into the energy mix of six selected remote villages that were pilot sites for national and foreign assisted solar electrification programs in three ecological regions of Nigeria. A total of 910 questionnaires were administered on the solar PV users, suppliers, and government agencies to elicit information on alternative energy sources for provision of energy services. The results showed that solar PV usage was 49.9 kWh per/day, which constituted an insignificant share of about 14% in the total lighting requirement and less than 2% of the total requirement for energy services. The demand would rise to 73.3 kWh per/day by 2019 at the same 14% share of the total lighting requirement. Firewood demand maintained over 80 percent share (2383.5 kWh per/day) in the total energy mix in 2009. It also revealed that the best policy option of 200 percent increase in solar bulbs’ share for lighting by 2014 would require 50% reduction in kerosene share. The study concluded that increasing utilization of solar PV for lighting, entertainment, refrigeration, and ventilation in the study areas could lead to decrease in the use of energy from alternative sources.
