Definition of Wind Energy “Wind Energy - Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans‚ earth‚ and atmosphere by the sun. Turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this

Wind Energy Wind energy is a free‚ renewable resource‚ so no matter how much is used today‚ there will still be the same supply in the future. Because the wind energy is also the source of the clean‚ and non- polluting‚ electricity.

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush‚ who ran his entire Euclid Avenue mansion off of one for 20 years‚ which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn’t rise a great deal afterwards‚ this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose

Background/History on the Wind Power Industry The wind power industry first developed in Iran around 200 B.C. The first windmills were vertical axis wind turbines‚ which were used for pumping water and grinding whole grains for food consumption. The Chinese‚ Romans and Afghans all used windmills around this time for similar use. In the 13th century Holland started developing large horizontal axis windmills. These four-blade windmills were larger‚ carried more torque and wind speed and could do more
