Energy can be divided into primary energy and secondary energy. The energy directly provided by nature is primary energy, and the energy indirectly obtained by consuming other energy is called secondary energy.
Therefore, wind energy and water energy are primary energy. Electricity is a secondary energy source.
Tides, geothermal energy and solar energy are the main energy sources. Biogas is a secondary energy source.
