Transcript of Wind Energy
Energy is a hot topic in the news today: increased consumption, increased cost, depleted natural resources, etc.
Wind energy has great potential to lessen our dependence on traditional resources and to do it without as much damage to the environment.
What is wind energy?
Is wind energy economically? feasible?
Is wind energy effective?
What affect does wind energy have on the environment?
How can wind be used in the U.S?
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.
According to the U.S. Department of Energy, the cost of wind energy has come down. 85% in the last 20 years.
The use of wind energy in America has gave 2.7 million people jobs.
Reports out of India states the use of wind energy will not break the bank.
Wind is abundant in this world, so it will never run out.
Wind turbines are also efficient, they have systems in them that help them save energy.
Start up at 4 to 5 meters per second max power at 15 meters per second.
Wind Turbines can last up to 20-25 years.
Wind energy should be used as the main source of energy in the United States because it is reliable, environmentally sound, and cost effective.
Harnessing power from the wind is one of the cleanest ways to generate electricity.
It does not produce any toxic pollution, global warming emissions, or water pollution.
wind turbines have very little affect on the environment and wildlife around them.
By: Daishon Washington-Allen
In conclusion wind power is currently the fastest growing source of electricity production in the world, and it should be used more in the U.S. because it is cost competitive, its efficient and does little harm to the environment and wildlife.

People have been harnessing power from the wind for a very long time. Since Early recorded history, people have been harnessing the energy of the wind.
Wind energy propelled boats along the Nile River as early as 5000 B.C.
The first windmill for electricity production is built in 1887 by professor James Blyth in Glasgow, Scotland.
In 1920 the current design for wind turbines was created by George Darrieus.
Wind energy can be used for many things
