It is the energy derived from sources that do not use exhaustible fuels (for example, water – hydroelectric power, wind – wind energy, Sun – solar energy, tides, and geothermal sources). Some combustible materials, such as biomass, can also be considered renewable. Usually, renewable energy generation (with the exception of geothermal and hydroelectric) does not emit greenhouse gases.
