How does wind energy work?Like old fashioned windmills, today’s wind machines (also called wind turbines) use blades to collect the wind’s kinetic energy. The wind flows over the blades creating lift, like the effect on airplane wings, which causes them to turn. The blades are connected to a drive shaft that turns an electric generator to produce electricity.

AdvantagesIt is a renewable sourceThere is no fuelLess space It does not polluteWind is free

Page 5: Wind energy

Thousands of wind turbines

DisadvantagesIt’s expansive to make a

turbineWind it self is not

dependableIt take hundred or

thousands are needed to produce enough energy

Kill’s bird’sMakes a lot of noise

Fun FactsAn average wind speed of 14 miles per hour

is needed to convert wind energy into electricity.

The largest wind turbine in the world, located in Hawaii, stands 20 stories tall and has blades the length of a football field.

Wind energy can be used in nearly 50 % of USA territory.

Wind energy can provide us with cleaner air and much healthier environment.
