On the end of 2006, worldwide capacity of wind-powered generators was 73. 9 gigawatts ; although it presently produces merely above 1% of world-wide electrical power use, it accounts for approximately 20% of electrical power use in Denmark, 9% in Spain, and 7% in Germany. Globally, wind electrical electricity generation a lot more than quadrupled amongst 2000 and 2006. Most modern wind electrical electricity is generated within the kind of electrical power by converting the rotation of turbine blades into electrical current by means that associated with an electrical generator.
In windmills (a a lot of older engineering), wind energy is utilized turn mechanical machinery to try and do physical work, for instance crushing grain or pumping water. Wind electrical electricity is employed in massive scale wind farms for national electrical grids and also in little individual turbines for providing electrical power to rural residences or grid-isolated locations. Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and greenhouse gas emissions when used to switch fossil-fuel-derived electrical power.
The intermittency of wind seldom creates problems when making use of wind electrical electricity at low to moderate penetration levels. There are plenty a large number of wind turbines operating, using a total capacity of 73, 904 MW of which Europe accounts for 65% (2006).
The average output of one megawatt of wind electrical electricity is equivalent onto the average electrical power consumption of regarding 250 American households.
Wind electrical electricity was possibly the most rapidly-growing means that of different electrical power generation on the turn in the century and world wind generation capacity a lot more than quadrupled amongst 1999 and 2005. There is an estimated 50 to 100 times additional wind energy than plant biomass energy obtainable on Earth.
Much of this wind energy may be found at large altitudes the place continuous wind speeds of above 160 km/h (100 mph) occur.
Eventually, the wind energy is converted through friction into diffuse heat across the Earth's surface as well as the atmosphere. Large-scale onshore and near-shore wind energy facilities (wind farms) may be controversial owing to aesthetic reasons and affect on the local environment. It must be noted, though, that will onshore and near-shore studies show that will the quantity of birds killed by wind turbines is negligible in comparison to the quantity that will die because of this of other human activities for instance traffic, hunting, electrical electricity lines and high-rise buildings and especially the environmental impacts of making use of non-clean electrical electricity sources.
