Wind power or wind energy is mostly the use of wind turbines to generate electricity. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network.

New onshore (on-land) wind farms are cheaper than new coal or gas plants, but expansion of wind power is being hindered by fossil fuel subsidies. Onshore wind farms have a greater visual impact on the landscape than some other power stations. Small onshore wind farms can feed some energy into the grid or provide power to isolated off-grid locations. Offshore wind farms provide a steadier and stronger source of energy and have less visual impact. Although there is less offshore wind power at present and construction and maintenance costs are higher, it is expanding. (Full article...)

Wind Powering America (WPA) is an initiative of the United States Department of Energy (DOE) that seeks to increase the use of wind energy throughout the United States. WPA collaborates with key state and regional stakeholders, including farmers, ranchers, Native Americans, rural electric cooperatives, consumer-owned utilities, and schools to break down barriers associated with wind energy development.

Throughout its history, WPA has focused on states with strong potential for wind energy generation but with few operational projects. WPA provides fair and unbiased information about the challenges, benefits, and impacts of wind technology implementation. This information allows policymakers, organizations, and citizens to make educated and informed decisions about wind energy implementation in their communities. (Full article...)

A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications. The term wind engine is sometimes used to describe such devices. (Full article...)
