Wind Power

How does it work? Wind turbines are usually made up of 3
propeller-like blades. The rotor is attached atop a tall tower
where the wind is more powerful. As the wind blows, it spins the rotor. As the rotor spins, the energy of the
movement of the propellers gives power to the generator.
The magnets and copper wire inside the generator produce the actual electricity
Waste Products The only harmful products of wind energy are
those that result from the:
Manufacture
Transportation
Maintenance
Of the wind generation equipment After the production phase, wind energy does not
produce any harmful byproducts.

Advantages Wind is free and can be easily captured for
energy use. No greenhouse gases or other pollutants
after the production phase. They take up little space and the land
surrounding the wind turbines is still available for use.
They are pretty. They can be used in remote areas (off the
grid).
Disadvantages Wind is not consistent. Not as efficient in producing energy as the
burning of fossil fuels. Without subsidies, wind turbines are not
economically practical.
Can kill birds.
Interesting Facts Can be bought for commercial or personal
use. Largest blade is 75m long with a rotor
diameter of 154m A single 1-MW wind turbine running for 20
years is equivalent to burning 29,000 tons of coal or 92,000 barrels
of oil
