Renewable Energy

Energy obtained from sources that are essentially inexhaustible (renewed on short time scales), unlike fossil fuels.

e.g.: wind, solar radiation, hydro power.

The IPCC definition:

Energy sources that are, within a short time frame relative to the Earth’s natural cycles, sustainable, and include non-carbon technologies such as solar energy, hydropower, and wind, as well as carbon-neutral technologies such as biomass.
