Abstract—This article examines and evaluates the potential of solar and wind energy resources in the southern part of Uzbekistan, Bukhara region. It also analyzes the cost and negative impacts of the region’s electricity consumption and emission of atmospheric greenhouse gases over the years. According to the results of the study, the greenhouse gas emissions from the Bukhara region are estimated at 74.8 million tons as of 2018 and annual electricity consumption is 3.4 billion kW h. The gross (theoretical), technical and economic potential of the region’s wind energy was estimated using the Rayleigh distribution function at different seasons and at different heights. According to analysis, the region’s total wind energy capacity is 4606 billion kW h/year at 100 m in spring, 6848 billion kW h/year in summer, 3799 billion kW h/year in autumn, 4778 billion kW h/year in winter. In order to see the effective use of wind energy the wind turbidity diagram (wind rose) of the region has been identified and analyzed for different seasons. Solar energy was evaluated as the most efficient in the region and it is estimated that the solar photovoltaic potential of the region was 41 TWh/year, and produced by solar collectors was 184 TWh/year. According to the research conducted, the renewable energy sources such as solar and wind energy in the Bukhara region can provide consumers with full electricity supply and environmental, social, economic problems, energy security, reliability and continuity can be eliminated. Keywords: greenhouse gases, electricity consumption, wind energy, Rayleigh distribution, solar energy, green energy DOI: 10.3103/S0003701X20040106
INTRODUCTION The demand for energy increases as the population growth, industrial and transport development, the development of science and technology, and the improvement of human lifestyles year after year. In this case, the reliability of energy supply requires an increase in the available energy sources, the use of alternative energy sources, and the introduction of energy saving measures. However, the increasing use of thermal power stations, which are now widely used in the world for generating electricity, can cause enormous damage to the environment. A number of environmental problems in the world causes this conclusion today. Thermal power stations are the main source of electricity in the country. The current environmental situation in the Republic is also partly due to the use of thermal power stations in the power supply. In this case, it is necessary to solve a number of urgent problems facing power engineering and scientific researchers of the Republic. These are the issues such as the use
