The Vattenfall utility company study found Hydroelectric, nuclear stations and wind turbines to have far less greenhouse emissions than other sources studied.. A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2 ...
Although wind power is a popular form of energy generation, onshore or near offshore wind farms are sometimes opposed for their impact on the landscape (especially scenic areas, heritage areas and archaeological landscapes), as well as noise, and impact on tourism.
Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] A short burst of high speed wind is termed a wind gust ; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval ...
In Denmark, wind energy met more than 40% of its electricity demand while Ireland, Portugal and Spain each met nearly 20%. [82] Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome.
According to economist Robert Godby at the University of Wyoming, who studied the impact of wind power in his state, the addition of 6,000 MW of wind power could generate over $2 billion in tax revenue and $10 billion in investments in ten years. He added that while it may not be enough to replace coal, its positive impact is considerable. [2]
Wind energy royalties and solar land leases are spurring economic revivals in rural areas, while agricultural communities benefit from carbon capture and energy storage projects.
Numerous positive environmental effects of wind power have been cited, including pollution avoided from electricity generation from fossil fuels as well as the fact that unlike electricity production from fossil fuel power plants such as coal or petroleum, wind power does not need to use water for cooling.

Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
