Energy obtained from sources that are essentially inexhaustible, unlike, for example, the fossil fuels, of which there is a finite supply. Renewable sources of energy include wood, waste, geothermal, wind, photovoltaic, and solar thermal energy. See hydropower, photovoltaic. (source: EPA)

Background from Wikipedia

Example of a traditional windmill

Renewable energy sources, or RES, are those energy sources which are not destroyed when their energy is harnessed. Renewable energy sources are distinct from fossil fuels, which must be consumed to release energy. Human use of renewable energy requires technologies that harness natural phenomena, such as sunlight, wind, waves, water flow, biological processes such as anaerobic digestion, biological hydrogen production and geothermal heat.

Traditional uses of wind, water, and solar power are already widespread; but the mass production of electricity using renewable energy sources has become popular only recently, reflecting the major threats of climate change, concerns about the exhaustion of fossil fuels and the environmental, social and political risks of extensive use of fossil fuels and nuclear power.

Many countries and other organizations (transnational organizations, municipalities, societies) promote renewable energies by specific development policies. Several statutory definitions of the term renewable energy have been adopted to define eligibility. For renewable energy use in modern societies see Renewable energy development. For a general discussion, see Future energy development.

Renewable energies are all sustainable energies.

Renewable energy resources may be harnessed directly, such as in solar ovens, geothermal heating, watermills, and windmills. They may require energy harvesting through appropriate technologies such as: electricity generation through wind turbines or photoelectrochemical cells (PEC)s, or photovoltaic cells, production of biofuels such as biogas from anaerobic digestion, or ethanol from biomass (see alcohol as a fuel).
