Wind energy is one of natural energy sources. Have you ever reflected about how such energy is generated? In simple English, energy is obtained by means of special turbines. These turbines change mechanical energy into electricity. Nevertheless, it is necessary to remember that wind turbines would create electricity only where the wind blows. Moreover, the speed of wind has to be stronger than “start speed”. Otherwise, turbines remain still and the energy is not manufactured.
What is highly essential, using wind power equipment is very profitable for environment. Thanks to this, it is possible to limit emissions of destructive carbon dioxide. How? By creating the electricity without burning any fuel.
The use of wind energy becomes more and more popular. This is expected that EU countries will triple the ammount of energy gained from wind until 2020. The popularity of popularity of wind energy is different in various countries. For example, Poland in 2011 was one of the EU countries with the least advanced wind power equipment. Last year, Poland was already in second place between all EU countries with regard to the lately launched wind power equipment and installations. This is estimated that this sector is going to be growing continuously. Possibly bcause of this reason, in Poland there are more and more specialized business involved in the installation of wind power equipment. On theforeign markets those firm are recognized for very good quality products.
Wind energy is used in various ways. Firstly, wind farms are becoming increasingly popular. They are comprised from a few power plants and turbines, which are located next to each other. A the same time, more and more wind energy is used by individuals in their homes. This enables to own an additional energy source.
Nevertheless, there is something in common when it comes to wind power equipment. Profitability of the investment in that depends on the location. Thus, previously buying wind power equipment, the wind speed is checked at various times of the year, frequently in summer and winter. Windless places are categorically disqualified because such investment might not be profitable there. Nonetheless, in many European countries there are many windy areas, in which this kind of technology would be highly successful.
