Definition Wind power

captures the energy of the moving air. As the sun heats the earth’s surface, it does it so unevenly that it creates wind cycles. By tapping into these wind cycles, we’re able to create wind power.

Parts of a wind turbine

•The power from the rotation of the wind turbine rotor is transferred to the generator.

•The wind turbine generator converts mechanical energy into electrical energy.

Wind energy is a resource which is classified as renewable

Operation of a wind farm

• A wind farm may also be located offshore.

• Wind mills can also be used for agricultural purposes.

An offshore wind farm

Advantages and disadvantagesAdvantages Disadvantages

Once the wind turbine is built, the energy it produces does not cause green house gases or other pollutants.

Many people find wind farms an interesting feature of the landscape.

Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply.

The strength of the wind is not constant and it varies from zero to storm force.

Many people feel that the countryside should be left untouched, without these large structures being built.

The largest single turbine available today can only provide enough electricity for 475 homes when running at full capacity.

CuriositiesGabbard offshore wind farm is the biggest in

the world and is located on the estuary of the River Thames.

Designed by an Arizona State University student, freeway sign wind turbines like these could generate enough electricity to supply a small apartment at low wind speeds.

Maple Ridge wind farm is currently New York’s largest wind farm, located in Lewis County. Operational since 2006, Maple Ridge is responsible for nearly 75% of New York’s total wind power capacity.

The world’s first floating wind turbine installed off the coast of Norway.

Another one of California's amazing wind farms, Tehachapi Pass is one of the oldest wind farms still in operation, since the early 1980's. About a dozen different companies generate electricity in the Tehachapi Pass wind farm. It is located in the Mojave Desert.

Conclusions•Renewable energy is very important and its use should be promoted.•It is not too expensive to get.•The air is a never-ending energy source.•It does not require the removal of too much soil.•It does not require too much work.•The space they occupy can be used for other purposes.
