Regenerative Energies

Regenerative or renewable energies are those energy sources or energy carriers that naturally renew themselves within human timescales. By definition they are very different from fossil fuels (coal, natural gas, oil) and atomic fuel (Uranium), which all came about only after millions of years of geological processes. Geothermal energy cannot be counted as a regenerative energy source, but its use is equated with renewable energy.

Regenerative energy sources are attributable to solar radiation: wind, waterpower, and biomass. The solar radiation is absorbed directly through collectors, wind through rotors, and waterpower through current or tidal power stations. Biomass energy is made available through burning (wood) or fermentation as well as gasification (silage, liquid manure).

Regenerative energies are available everywhere and can be adapted for use in the energy mix in any of the ways mentioned. This is ecologically sensible, socially compatible and promotes economical flexibility and innovation. Since April of 2000, the Renewable Energy Sources Act (Erneubare-Energien-Gesetz, EEG) has had the goal of doubling the proportion of regenerative energy use by 2010 in Germany.
