Calculation of the nominal power and electrical energy of the hydro power plant on an electronic calculator

Today, approximately 70.4% of the electricity produced in the world is provided by thermal power plants, 15.2% by hydropower plants, and 14.4% by solar, wind and other types of power plants. This indicator produces approximately 87 % of electricity in the Republic of Uzbekistan by thermal power plants, 10.2% by hydropower plants, and 2,8% by solar and wind power plants. It can be seen that meeting the needs of electricity on a global scale is mainly done through fossil resources. The sharp decline of underground reserves, now requires the need to find a solution to the problem of creating alternative energy sources. For this reason, the problem of electric energy is also serious in the Republic of Uzbekistan, and the cheapest electricity is obtained through hydroelectric power stations. The reason is that 1 kW of electricity received through hydroelectric power stations is 295 soums.
