Wind power is generated by converting the kinetic energy of wind using wind turbines. A wind turbine uses wind to turn blades which spin a shaft connected to a generator, producing electricity. Wind farms are places where many wind turbines are clustered together in windy areas. The electricity generated is sold to power homes, businesses, and schools.

2. 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.

3. 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.

4. Wind farms
Wind 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.

6. 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.

7. • 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.
