Importance Of Wind Energy Essay

Wind Energy as a Source of electricity Humans have used wind as an energy source for a very long time. Babylonians and Chinese used wind power to pump water to irrigating crops,4,000 years ago, sailing boats were present way before that. Wind energy was utilized in the Middle Ages, in Europe, to grind the corn, where the term "windmill" was created.

Wind energy is created when the sun unevenly heats the atmosphere, so patches of the atmosphere become warmer than others. These humid air patches rise, and other air blows to take their place, and that’s when we feel wind blowing. Energy can be harnessed in the wind by creating a tall structure with a propeller that is large on top. As the wind blows, the propeller rotates, which turns a generator to create electricity. These towers tend to be built in numbers together to make a wind farm, which produces more electricity at the same time. The more wind, the more towers and the greater propellers,

The only time that wind energy has contributed to pollution is while the wind turbines are built. But even that produces only minimal pollution to the environment rather than coal and oil power plants. When compared to the environmental impact of fossil fuels, wind energy is relatively minimal. Wind energy also has the lowest global warming potential per unit of electrical energy generated if compared to low carbon sources of power. Wind is abundant, affordable, and inexhaustible, which makes it a large-scale and viable alternative for fossil fuels. When considering the effects of wind energy on wildlife and their habitat, the most notable are the birds and bats that have been documented and studied. An NWCC or National Wind Coordinating Committee review of peer- reviewed research found evidences of deaths of birds and bats caused by collisions with the wind turbines and also because of changes in the air
