ENERGY SOURCES

Energy sources are natural resources that we can use to generate different forms of energy. Then we can transform that energy for various purposes.


We can classify energy sources into two general categories:

1.Non-renewable energy sources

Come from natural resources that are limited and can be exhausted. They include:

-Fossil fuels (oil, coal ...)

-Nuclear energy (radioactive materials)

2.Renewable energy sources

Come from natural resources that we cannot use up completly. These include: hydroelectric, solar, marine, geotermal and biomass resources.
