Global Energy Crisis And Renewable Energy Sources

The sudden development of the mankind at the turn of the 19th and 20th centuries brought along the growth in importance of exploiting the energy of different type. When uninterruptedly a demand for the energy is growing, and abilities of increasing the supply for her are limited, we can deal with the occurrence of an energy crisis. The article is moving the subject matter of an global energy crisis. A definition of an energy crisis, his genesis and effects were included in it for world economies, as well as ways of the fight against it in various countries. It is introducing data concerning the supply the energy in the world and of demand for it. It is presenting information concerning using different energy sources in final years. The article is moving also a subject matter of renewable energy sources (RES) and their meaning in the fight against an energy crisis. At the work an available literature on the subject, as well as publications and reports were used International Energy Agency, British Petroleum, U.S. Energy Information Administration, as well as the Goods Stock Exchange of the Energy. The article has survey character, letting understand the commercial distress of energetics, as well as the threat to world economies an energy crisis is carrying which. Growing demand for the energy, more and more difficult access to deposits of fuels and the increasing population numbers, in particular in developing countries, deepening problems in guaranteeing the access to the energy cause. It is hard explicitly to determine, what role in the fight against this phenomenon renewable energy sources will play. In them great hopes are being bent, but economic reality in particular, is verifying them. RES are uncertain, expensive and rather ineffective economically.
