Wind power

Wind power is kinetic energy of the wind which is changed into electricity with the help of wind turbines. It is renewable energy and it doesn't produce greenhouse gas emissions during operation. The biggest number of wind turbines exist in the United States and the coast of North Sea, for example in Denmark where 40% of its electricity generation was produced with the help of wind turbines in 2014. Still the countries that use wind power the most are the United States and Germany. 
There are more than 21,000 wind turbines in Germany and they produce 7.7 % of German's total electrical power. A fast development has also started in China and France. 



 The development of wind power in Finland has been more modest compared  to other countriesBy the end of 2014 there were only 260 wind turbines in Finland. Most of the wind turbines are located in the West Coast and only 1,3% of all electricity consumption was covered by wind power.

 The cost of production of wind power decreases as the usage of wind power increases. Since wind doesn't cost a thing, its operational costs are close to zero once a turbine has been erected. Its effectiveness has improved and consequently the usage has increased.
