For the industry sector it is the basic precondition for its existence. For every little step within the production process, being the production of a good itself, the handling with raw materials or the transportation of the final product to the customer, plenty of energy is required. Private households also consume a lot of energy. But due to the global population growth, the available earth's resources have come under enormous pressure to meet the humans' energy needs (Perez Latorre, 1999, p. 2). In the last 30 years the world's population has grown by more than 30% (www.weltbevoelkerung.de) and reached the present status of about 6.6 billion people (www.cia.gov). The total energy consumption has even increased more quickly comparing to the number of people on the planet. At the same time the population continues to grow and is estimated to reach about 9.1 billion people by the year 2050 (www.un.org). As the supply of oil, gas, coal and uranium, so called classic energy resources, is quite limited, the increase of population could result in the energy supply shortfall with considerable economic and social consequences. But this is not the only problem. The reserves of fossil fuels are distributed unequally over the globe (BMU, Renewable Energies - Innovations for the future, 2006, p. 11). The high dependence of energy-hungry industrial countries from energy supplying countries can even lead to political conflicts. Furthermore the use of these energy resources has significant environmental effects. The capacity of the environment to absorb the waste produced by the energy consumption is strictly limited, too. These waste pr"
