Wind energy has been harnessed since the 19th century in the form of windmills for mechanical energy. The 20th century brought the wind turbine which is used to create electricity.
Wind is actually a product of solar energy. The sun’s rays heat the Earth’s surface creating temperature differences between the land, water, and air, given their different propensities to absorb heat. This phenomena, in conjunction with the temperature differences that exist between the equator and the Earth’s poles, creates wind as hot air rises, expands, becomes less dense, and is then replaced by denser, cooler air (nesea).
Historically wind energy produces electricity at an average of about $.04 per KWh.
AeroVironment has operated since 1977 with over 250 sponsored projects to date. Primarily operate in California and principal researcher on the California Energy Commission
Boston’s Logan airport currently has 20 turbines on their office center combining for an annual savings of $13,000.
Maui Ocean Center has 6 turbines for 48,880 KWH per year.
