Wind power

Wind power has had the wind in its sails. It is a renewable energy source which is so well developed that it can be expanded on a large scale. In Germany, USA and China wind power has increased its contribution to energy supplies a great deal in recent years.

Wind power produced 2.5 % of the world´s electricity in 2011. The most common type of wind power plant has 2 MW of power and can supply 1,300 households with electricity. In Sweden wind power grew a lot during 2011. At the end of the year, the total amount of electricity produced was more than an average nuclear plant.

A windpower plant has a wind turbine with blades that rotates at different angles to catch the wind in the best way. If the wind speed doubles, the power increases eight times. A generator converts spinning into electricity.
