Renewable Energy and Biofuel

Scientific Study from the year 2009 in the subject Environmental Sciences, , language: English, abstract: Regenerative energy discloses primary energy sources from the natural systems of the Earth, sun and moon. Energy streams are caused by releasing energy from the rays of the sun or from solar radiation, the planet gravity and planetary motion, as well as the released warmth stored in the Earth. On the base of energy streams, these energy donators can provide final energy or useful energy. In this case one can also speak of secondary energy. The result is an extensive offer of power production. Regenerative energy shows the only reliable possibility to guarantee the energy supply of the earth with lasting effect and a low level of emission, as well as the execution taken from the Federal Ministry of environment, nature conservation and reactor security. On a global scale, around sixfold of the whole energy consumption could already be covered by technically usable regenerative energy today. For states dependent on raw material or on energy like Germany, regenerative energy means more independence from energy used by fossil oil and natural gas.
