2How Wind Energy WorksWind 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.
3Wind EnergyThe process by which the wind is used to generate mechanical power or electricityHistorically windmills were used to pump waterToday turbines are used to harness the wind for energy
4Advantages of Wind Energy Safe for the environment – no fossil fuels are usedWind turbines do not take up as much space as an average power stationWind is freeWind will always be available.No polluting waste is released
5Disadvantages Of Wind Energy How much wind is unpredictableWind turbines are noisyCan be an eye-soreProduce less electricity than fossil fuelsInstallation can get pricy
6Wind Turbines Use wind to make electricity Wind turns the blades that turns a shaft that is connected to a generator that makes electricity.
7History on Wind EnergyEarliest 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 EuropeUsed to drain marshes and lakes by the Dutch
8The 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
