There is a rapid development of the technique (see Figs. 9). So for 20 years since 1982 till 2002 unit capacity of wind turbines has increased almost in 60 times, and the height of a basic tower and diameter of working vanes have increased in 6 times. These are very important parameters as with growth of height of the unit increases both a flow velocity of air, and a degree of its stability. Each of units positioned today with capacity in 1,5-3,0 thousand kW is capable to provide with power a decent human settlement.

That is something to think about for Russia. Today its place in series of the countries using a wind power, alas, near to Luxembourg. Belarus is even not mentioned in this list. In addition, in fact it is known, that in the sixtieth years of past century in Belarus it was totalled about 20 thousand wind generators of various purpose. Were both windmills, and water-raising devices and even wind electric units? Moreover, nobody thought, that wind energy resources of Belarus are not sufficient for their economic utilization. Today’s researches of Belarusian power engineering specialist and criminologists enable to evaluate wind energy resources of the Republic on electric potential in 223 billion kW-hour. Annual requirement of a national economy for the electric power on the data on 2002 approximately estimates in 40 billion kW-hour. That means that reasonable utilization of resources of wind could provide practically all energy demands of the country. For now Eugeny Shirokov, one of the Belarusian enthusiasts of utilization of renewable energy with pleasure reports, “Belarus now has the wind driver generator” [95]. As they say, that is just the beginning. Let’s hope, that Belarus even in this question will go on ways of civilized countries.

Figs. 9. Growth of unit power of windmills in Germany

Today Germany does not build nuclear power plants. This already important achievement of people of Germany. Instead of atomic monsters fast as mushrooms in kind weather, grow all new and new wind electric installations. Immediately they would substitute by themselves all those atomic mines, which unreasonable people put on the territory of Germany! But do not delude yourself: in Germany there are forces which earned earlier and very much would like to earn hereafter huge profits from construction of NPPs at home, and in other countries. These people do not take care about consequence of their “activity” for all of us and for all alive on the Earth. Their purpose – to fill the pockets, earning everything that they manage to get, from our pockets.

However, in implementation of wind power, there are countries - leaders. These countries incomparably smaller than Germany, but on installed capacity of windmills per unit of area of country, they are ahead of the whole planet. First of them is Denmark – 32,66 kW/ sq. km. Behind it go: Holland – 10,80 kW/sq. km; Germany – 8,01 kW/sq. km and Spain – 1,65 kW/sq. km.

The question of the cost price of wind power is undoubtedly important. On the data on the end of past century the cost price of production of the electric power at the expense of a wind has reduced for 20 years more than in five times – from 30 cents for 1 kW-hour in the beginning of 80^th up to 3-6 to the beginning of new century [92]. It is already quite acceptable and is much cheaper than the electric power produced on NPPs. Analysts predict, that to 2012 it will be equal to the cost of traditional sources of the electric power. Is present quite reasonable supposition, that utilization of power of renewable sources is braked not because of technical or price problems, and because of the competition, that is because of unwillingness to yield a part of the market to new technologies.

The commission of the European Union in 1997 has approved the strategic document with rather characteristic title – “White Paper” [90]. Draftsmen have offered to result everything, that was done in the sphere of energy in past, and to begin all anew, with “a white sheet”. According to this program it is planned to increase to 2010 production of power at the expense of renewable sources in 2 times in comparison with 1995, that is about 6 % up to 12 % from its general production. However, having evaluated possibilities of EU countries, the parliament of the European Union has increased the scheduled level up to 15 % on 2010. The large part of this increment will be provided at the expense of wind energy.

However, Germany in this questions a favourite. “The multiple increase of part of renewable energy sources is planed: from 7 % in 1998 up to 50 % to 2020” (W. Bahm. 1999) [65]. It agrees to the principles of power policy developed by nature protection organizations, to year 2030 in Germany 75 % of requirement in power it should to be provided at the expense of renewable sources. Very similar on a fantasy. But, seeing as Germany actively goes to the clean, “green” world, it is possible to believe in it. And to wish success!
