It is an important economic indicator for countries, as well as a combination of the development indicator, how the clothes are made. Because how much electricity is produced from which source, how efficiently this production efficiency is used gives serious direction to school economic policies. From this situation, it summarizes how the electrical energy produced in Turkey between the years 2011-2020 has changed on a yearly basis, what the production values are and what share it has in the total production from these sources. Ensuring the results achieved, except for the year 2019. In all other years the electric power plant has always been a series compared to the previous year. In addition, from 2011 to 2017, electricity generation from natural gas was always the leader, while after 2017 this situation was caused by coal.

Electrical energy is used in many sectors and in all areas of daily life. There are many important aspects of electrical energy production. The first of these is the economic aspect. Electrical energy is a key driver of economic growth and industrialization. Many businesses such as industrial plants, production lines, factories and offices need electrical energy. Electrical energy is also used in many sectors from agriculture to health services, from communication to transportation and plays a critical role in sustaining economic activities. On the other hand, if it is considered in terms of quality of life, electrical energy is a basic requirement in many areas of daily life. Many activities such as lighting, heating/cooling, cooking, water supply, communication, information technologies, entertainment and electrical devices are carried out with electrical energy. Without electrical energy, the comfort and efficiency of modern life is greatly reduced. In addition, the environmental effects of the resources used in electrical energy production are of great importance in terms of sustainability. Renewable energy sources, especially sources such as solar, wind, hydroelectric and geothermal, provide an environmentally friendly energy production. These resources reduce greenhouse gas emissions and play an important role in tackling climate change. One of the important aspects for countries is undoubtedly energy security. Providing electrical energy production from local sources is important in terms of energy security. An energy portfolio based on a variety of energy sources ensures diversification of energy supply and stabilization of energy supply. This increases the country's energy security and reduces foreign dependency. In addition to these, it has many contributions in terms of innovation and technological developments. Electric power generation encourages the development of innovative technologies. It continuously makes
