Energy is the Key: Renewable Energy Problems in Germany

Abstract: The basic requirements for a steady, demand-oriented, economic and environmentally compatible energy supply are defined and the electrical energy produced by wind, sun and bio-fuel are then rated accordingly. Although renewable energies have made considerable progress in some respects, they have major shortcomings when compared to conventional energy sources when all factors are considered. One of the main reasons is the extremely low energy density characteristic that renewable energy sources have. Another reason is the unsolved problem of the highly uneconomical large-scale storage of electrical energy, and with still no solution in sight. Bio-fuels can be stored and are thus an exception. But they have enormous problems in other areas. The deficiencies for all types of renewable energies are discussed in detail and illustrated with example calculations.
