Importance of Energy Efficiency in Power Engineering

This paper aims to show the importance of energy efficiency in the power engineering, that it is essential to all areas of the economy and society, as well as for the environment. While saving energy always involves certain sacrifices from the usual habits, efficient use of energy has led to increased quality of life, greater competitiveness of companies and the economy as well as energy security. Energy sources that are most in use today are based on the combustion of fossil fuels, and supplies of these fuels have their limitations and should be used more efficiently, thus improving energy efficiency by implementing certain measures in this field
