Finite oil reserves and decline of production in oil fields is the reality. Each litre of the newly discovered oil equals to four litres of exploited oil. At present, 54 of 65 biggest oil producing countries are behind the peak and the output declines. This is happening in spite of the extremely high prices, political support and use of new technologies. It suggests that the world is approaching the point where the oil production can’t raise anymore – the oil peak. More and more experts predict that the oil peak is going to happen before the year 2010. Civilization never faced the challenge comparable to oil peak. The peak doesn’t mean that the oil reserves are depleted; it means that the increase of production has stopped. This is a challenge for renewable energy sources, the only alternative capable to supply man with safe, clean and cheaper energy.
