Bioenergy is organic matter of plant or animal origin that can be used in solid, liquid, or gaseous states.

Wind is the movement of air masses, caused by differential heating of zones in the atmosphere or by the orography of the terrain.

Geothermal energy is energy obtained from heat originating from the Earth's interior.

Hydropower production takes place in hydroelectric power plants that may have reservoir storage or be run-of-river plants.

The energy available in the sea is very abundant.

Producing electricity using the sun is possible through photovoltaic solar panels or thermal solar panels.
