Wind energy is one of the renewable energy sources. Have you ever wondered about how such energy is created? Basically, energy is obtained by means of certain turbines. Those turbines change mechanical energy into electricity. Nonetheless, it is necessary to remember that wind turbines could produce electricity only when the wind blows. What’s more, the speed of wind gotta be greater than “start speed”. Otherwise, turbines remain stationary and the energy will not be manufactured.
What is highly important, using wind power equipment is extremely beneficial for environment. As a result of that, this is possible to lower emissions of harmful carbon dioxide. How? By generating the electricity without burning any fuel.
Using wind energy becomes very popular. It is expected that EU countries are going to triple the number of energy gained from wind until 2020. The scope of using of wind energy varies in various countries. For example, Poland in 2011 was 1 of the job (see (see details)) countries with the least advanced wind power equipment. Last year, Poland (underground mining machines) had second place between all EU countries concerning the recently launched wind power equipment and installations. It is estimated that this sector will be growing continuously. Presumably for that reason, in Poland there are many specialized company involved in the installation of wind power equipment. On the international markets these firm are recognized for very good quality products.
Wind energy is used in various ways. First of all, wind farms are starting to be increasingly popular. They are comprised from a few power plants and turbines, that are placed close to each other. A the same time, more often wind energy is used by private people in their homes. This allows to have an additional power source.
Nonetheless, there is one thing in common when it comes to wind power equipment. Profitability of the investment in such equipment depends on the location. In consequence, before buying wind power equipment, the wind speed is measured at various times of the year, usually in summer and winter. Windless areas are categorically disqualified because such investment may not be profitable here. Nonetheless, in many European countries there are some windy regions, where this type of technology will be extremely profitable.
