wind energy

What is Wind Power? Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to produce electrical power.

How a wind turbine works ?

• Turbine uses wind to make electricity.• The wind turns the blades, which spin a shaft, which

connects to a generator and makes electricity. The electricity is sent through transmission and distribution lines to a substation, then on to homes, business and schools.

Wind farmsWind farms are places where many wind turbines are clustered together. They are built in places where it is nearly always windy. The electricity that is generated at a wind farm is sold to electricity companies that provide the electricity to people living in cities and towns.Wind farms can have as few as five wind turbines or as many as 150.

Did you know...• The largest wind turbine in the world, located in

Hawaii, stands 20 stories tall and has blades the length of a football field.

• An average wind speed of 14 miles per hour is needed to convert wind energy into electricity.

• One wind turbine can produce enough electricity to power up to 300 homes.

• The first power-generating turbine was constructed in Ohio during the late 1800's and was used to charge batteries.

• Wind energy is the fastest growing segment of all renewable energy sources.
