energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because it is a source of renewable energy that is both sustainable and poses minimal costs to the environment. Wind power has been around for many centuries‚ and has steadily developed over the last 100 years. The first major usage of wind power in the United States was between 1870-1930 when farmers used wind energy to pump water (Union

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. Wind energy is friendly to the surrounding environment‚ as no fossil fuels were to generate electricity from wind energy. Wind Energy is a viable industry that has become energy source. The energy generated from wind is clean and efficient. The wind energy industry

“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

There is also a group of people that believe that the wind turbines that are used to generate wind energy is a bad idea because they obstruct the natural view‚ causes death to birds‚ and generates noise pollution. They also argue that wind energy is
