2. How Wind Energy Works
Wind is a type of solar energy. Heating by the sun causes air mass to move from a higher pressure to a lower pressure. The kinetic energy from the moving air is translated into electrical energy.

3. Wind Energy
The process by which the wind is used to generate mechanical power or electricity
Historically windmills were used to pump water
Today turbines are used to harness the wind for energy

4. Advantages of Wind Energy
Safe for the environment – no fossil fuels are used
Wind turbines do not take up as much space as an average power station
Wind is free
Wind will always be available.
No polluting waste is released

5. Disadvantages Of Wind Energy
How much wind is unpredictable
Wind turbines are noisy
Can be an eye-sore
Produce less electricity than fossil fuels
Installation can get pricy

6. Wind Turbines Use wind to make electricity
Wind turns the blades that turns a shaft that is connected to a generator that makes electricity.

7. History on Wind Energy
Earliest use of wind power started with the sail boat.
First windmills were created to pump water and grind grain.
Used for food production in the Middle East and then transferred to Europe
Used to drain marshes and lakes by the Dutch

8. The Future of Wind Energy
Modern turbines could produce three times as much energy used in 1990, if strategically placed worldwide.
Produces no pollution, so wind energy doesn’t contribute to global warming or acid rain.
Wind energy costs are coming down while other types of energy are rising.
