In simple terms, electrical energy sources are the origins that supply power for generating electricity. These sources can be renewable (like solar and wind) or non-renewable (like coal and natural gas). Understanding them is essential to know how electricity reaches us and why some sources are more sustainable than others.
Electrical energy is not a primary source of energy. It is a secondary source because it is produced from primary energy sources such as coal, natural gas, nuclear energy, solar energy, and wind energy. These primary sources drive electric generators and solar cells to produce electricity for easy use and transport.
The process of electricity generation varies depending on the source of energy used. However, most methods involve converting some form of mechanical energy into electrical energy by using a generator.
Electricity is both a basic part of nature and one of the most widely used forms of energy. The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy, and wind energy into electrical power.

Electricity is the movement of electrons between atoms Electrons usually remain a constant distance from the atom''s nucleus in precise shells. The shell closest to the nucleus can hold two electrons.
