Wind Energy

Wind EnergyBy Emma and mentor Karin Wadsack

{How 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.

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

Advantages of Wind EnergySafe 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

Disadvantages Of Wind EnergyHow much wind is unpredictable

Wind turbines are noisy

Can be an eye-sore

Produce less electricity than fossil fuels

Installation can get pricy

Wind TurbinesUse wind to make electricity

Wind turns the blades that turns a shaft that is connected to a generator that makes electricity.

History 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 Europe

Used to drain marshes and lakes by the Dutch

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 doesnt contribute to global warming or acid rain.

Wind energy costs are coming down while other types of energy are rising.
