| Abstract |
The last decade international community pays great attention to development and introduction of one of the perspective directions of fuel and energy saving - the renewable energy sources, which are practically inexhaustible and ecologically clean. Analysis indicates that increase of population causes rise of energy consumption, but according to the optimistic scenarios shortage of organic fuel will arise in 70 to 100 years. However, that is not the only problem, the process of energy production involving organic fuel, nuclear or thermonuclear energy is accompanied by emissions, leading to "heat pollution" of the environment. There is an opinion, that warming of the atmosphere by 3.5 degrees is a critical value that may lead to global climate change and initiation of greenhouse effect as the increase of carbon dioxide concentration causes the ecological climate to deteriorate. So the precedent is created: in struggle to achieve efficient and universal energy consumption the community finds itself in low controlled conditions of existence and dependence of usage of organic element. Realising these problems and being aware of the situation, we consider, that the main trends of development of contemporary power engineering are to be based on compromise, in particular: . wide usage of renewable energy sources; . development and introduction of efficient energy-saving technologies in traditional power engineering. |
