| Abstract | When talking about energy nowadays we often associate on concepts such as environmentally friendly technologies, climate protection or renewable energy. With the spread of fossil fuels (such as crude-oil derivatives, natural gas or hard coal) the carbon dioxide concentration of the Earth has increased by 25%, while the methane gas concentration by 50%. As a result green house effect emerges, the atmosphere overheats, the polar ice fields melt and a rise of the level of the seas can be anticipated, seaside cities and hereby 40% of the mankind run into danger. Member states of the Earth declared at an agreement in Rio de Janeiro and Kyoto for the protection of climate, that the future of mankind is the stake and prescribed the reduction of the use of fossil fuels by 6% annually. Carbon dioxide can be reduced by forestation, and the most obvious method for the reduction of methane is the replacement of the fossil fuels for environmentally friendly renewable energies. In Hungary it can be biomass, solar, wind or geothermal energy. From the current domestic energy necessity of 1,052 PJ only a couple of percentages are renewable energy. Its proportion was determined in 7.2% by government |
