Wind Power!
When you think “Modern Wind Technology”, think of Power Plants.

These power plants include wind turbines that are powered by the wind in order to turn a turbine that powers a generator, and creates electricity that can be used and stored.

To understand the parts of a turbine and how it works, check out the following websites:

One wind turbine generates approximately 2 MW of power.
Wind is less than 1% of the commercial energy market.
Positives:
-No emissions (CO2)
-Multiple land use because of small footprint
-Could go longer than solar power (because of night and day)
-Renewable Energy
Negatives:
-Noise pollution (from the blades)
-variable wind supply (need storage and backup)
-Aesthetics
-Some habitat laws (birdstrikes-birds sometimes fly into them)
This is a funny video from class : ) :

I think you meant LESS than 1% of energy market. Also, the power supplied is variable with wind supply. Noise pollution comes from the spinning blades, but is not variable. Finally, we did not discuss habitat laws, but birdstrikes are a negative. Just needs a little proofreading, KD.

Good adjustments-thanks.
