Wind Power

 

Wind turbines operate by producing mechanical power from the energy present in wind.

As wind blows, this turns the blades of a wind turbine to produce mechanical power.

This power is then collected and used to generate electricity.

Wind power is still an indirect form of solar power due to the fact that the land, sea and atmosphere warm up at different rates due to solar radiation. This causes differences in air pressure and therefore the resulting winds are created.

Different sized turbines are available for electricity generation, producing from a few watts to several mega watts of power.

They have a variety of uses including, as examples, battery charging on a boat, electrical heating or feeding power into the National Grid for use across the United Kingdom.

Wind power is one source of renewable energy which helps to reduce electricity bills and decrease our contributions to global warming.

For the use of wind power, we need a site that is windy and free of obstructions such as nearby tall buildings or pylons. Wind speeds increase quickly above the ground, so turbines are built to safe heights but high enough to harness as much wind power as possible.
