Leveraging the nation's abundant wind resources for electric power generation helps the nation increase its competitiveness, diversify its energy supply, increase energy security and independence, reduce emissions of air pollutants, save water that would otherwise be used. Leveraging the nation's abundant wind resources for electric power generation helps the nation increase its competitiveness, diversify its energy supply, increase energy security and independence, reduce emissions of air pollutants, save water that would otherwise be used. Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. Today, wind power is generated almost. Wind energy is a form of renewable energy, typically powered by the movement of wind across enormous fan-shaped structures called wind turbines. Once built, these turbines create no climate-warming greenhouse gas emissions, making this a “carbon-free” energy source that can provide electricity. wind power, form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. As renewable energy technology continues to advance and grow in popularity, wind farms like this one have become an increasingly common sight along hills.
