What is wind energy?
How it works:
This link has an animation that shows how wind turbines work:

Materials needed and cost:
It would cost about $48,000 to $65,000 to install, and about $40,000 for equipment.
Maintenance:
Pros:
1.Clean source-doesn’t pollute the air or use destructive chemicals
2.Renewable-not limited and is free
3.Cost effective-don’t have to invest any cash
4.Extra savings for landowners-get paid to use land for a wind turbine
5.Rapid growth and huge potential-the amount of wind energy is increasing
6.Can be built on existing farms-doesn’t occupy much space, so farmers can continue to work on landCons:
1.Wind reliability-if it isn’t windy there is no power
2.Noise and visual pollution-they’re noisy
3.Expensive to set up-extremely costly and hard to maintain
4.Safety of people-severe storms can cause damage to blades which can be a safety hazard to people working nearby
5.Suitable to certain locations-need to be set up in an area with high winds
6.Effect on environment-takes up a lot of space (may cut down trees for space)sources:
