Wind Power

What Is It? Where Can It be Found?

Wind power , is a type of solar energy, captures the natural occurring wind in the atmosphere and transfers it into mechanical energy then electricity. Wind power can be found anywhere around the world. In fact, the amount of wind power installed has increased dramatically over the years.

How Is It Harnessed? Is It Being Used Now?

The way wind power is harnessed is that wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Yes it is being used now and its' the fastest growing renewable source in the world.

Different Types Of the Source

Environmental Impacts

Economic Impacts

"The major types of wind power are:

  • Utility-scale wind, wind turbines larger than 100 kilowatts are developed with electricity delivered to the power grid and distributed to the end user by electric utilities or power system operators;
  • Distributed or "small" wind, which uses turbines of 100 kilowatts or smaller to directly power a home, farm or small business as it primary use;
  • Offshore wind, which are wind turbines erected in bodies of water around the world, but not yet in the United States."

To What Extent Does the U.S. Use It?

An environmental impact on wind energy is wildlife. Studies show that many bats and birds have died from windmill blades. Windmills are high in the sky this causes birds and bats to fly into them.

What Other Countries Use It?

Wind energy became the number-one source of new U.S. electricity-generating capacity for the first time in 2012, providing 42% of all new generating capacity. As together they accounted for more than 55% of all new U.S. generating capacity.

Wind Turbines

The use of wind power in the U.S. is expanding quickly, Texas has the most wind turbines installed than any other state in the U.S. The U.S. has a total of 29,440 Megawatts (MW) of wind energy installed in the U.S. alone. And an additional 5,866 MW are under construction. Wind energy is one of the fastest growing sources of electricity in the world. The United States passed Germany last year to become the world leader in wind energy installed.

Many countries use wind energy such as the U.S. About 5%of India's energy is being supplied by wind power generation. The top ten countries where wind turbines are used most efficiently are: U.S., India, Germany, France, Spain, China, Denmark, Italy, Portugal, and U.K.
