What are renewable energies?
Renewable energy is energy from sustainable sources like hydropower, wind energy, solar power, biomass and geothermal energy. In contrast to fossil fuels like crude oil, natural gas, hard and brown coal and uranium ore, those energy sources do not consume theirselfs. Renewable energies are stocked for example in stationary battery systems or in gas stores. High energy density and concentration on tiniest space lead to critcial situations.
