In contrast to traditional forms of electricity production of solid, liquid, and gaseous fuels, which requires enormous costs that fuel is extracted from the earth, brought to power plants, burned, remove the ash to clear the smoke, warm water water сooling towers and reduced atmospheric air pollution, wind power plants of such costs is required.
But often mistakenly thought that the wind is no cost energy resource and wind power produced electricity also cost nothing. Unfortunately, the wind power plants are expensive. Expensive is their installation and connection to the system power supply, covering the purchase of land for the construction, transportation of heavy elements to the construction site, difficult installation, transformer construction, laying of cable lines, electrical connections, start-up and alignment, etc.
Not cheap and operational maintenance of wind power, which must be carried out under the strict instructions of the manufacturers. Crammed with electronic wind power plant maintenance should be specially trained professionals who are able to quickly find the cause of the problem and remove it.
