Humans tamed the power of wind long time ago. The sailing vessels first appeared 3,000 years ago, thank to which people were able to cross seas and oceans. The windmills were first constructed 4,000 years ago in Mesopotamia to grind corn and spices, as well as to squeeze oil out of oil seeds. This technology helped to produce flour, spices and seed oil. The windmills were also used to run sawmills, pump and sewage stations. There were several types of windmills like post mills, drain mills and tower mills. Greece and Holland were famous thank to their large windmill parks. Moreover, ancient Greeks worshiped eight different Gods of Wind!
The electricity production out of wind power is a relatively new invention. Only in 1887 James Blyth from Scotland came up with an idea to use the power of wind to produce electricity on his dacha. This technology could also help improving the climate change. Starting from micro wind turbines and small wind generator introduced on the house roofs, which can produce enough electricity for a radio or various household purposes, to huge offshore wind turbines of 8 Mw total power. To date, four percent of electricity is produced by wind. Number one electricity producer, who uses the power of wind is Denmark, as one third of its electricity volume is produced by windmills. Only fool, like Don Quixote will fight against the windmills today.
The power of wind can be also devastating. The windstorm can damage roofs and create dangerously high waves. In the wide open Kazakh steppes the power of wind increases dramatically and in winter it is called a snow-storm (buran). It is not a coincidence that a Soviet spacecraft was called Buran, as it symbolizes its great power.
In windy regions the expenditures on electricity production by windmills are lower than the production based on coal or nuclear energy. Kazakhstan can become one of such places soon! Even despite the fact that only 10 percent of our energy is now produced by the windmills, the general tendency shows an increase.
In a long-term perspective the wind energy is more promising than any other. On the territory of 50,000 square kilometres, which composes 2 percent of total area of the country the annual average wind speed composes more than 7 m/s. This territory provides possibility to produce 1 trillion W/h annually, which is tremendously more than the country even needs.
The features of time are obvious now: new windmills are working in windparks in Korday and Erejmentau. Next parks will be constructed in Almaty, Aktobe, Karaganda, Akmola, Zhambyl, Kostanay and East-Kazakhstan regions. It is expected that 3 percent of electricity will be produced by the windmills by 2020.
