  1. Wind Energy By Emma and mentor Karin Wadsack

  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. THE FUTURE OF WIND ENERGY
