Wind Energy


We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that.

Wind power was used in the Middle Ages, in Europe, to grind corn, which is where the term "windmill" comes from.


How it works

The Sun heats our atmosphere unevenly, so some patches become warmer than others.

These warm patches of air rise, other air blows in to replace them - and we feel a wind blowing.

We can use the energy in the wind by building a tall tower, with a large propellor on the top.


The wind blows the propellor round, which turns a generator to produce electricity.

We tend to build many of these towers together, to make a "wind farm" and produce more electricity.

The more towers, the more wind, and the larger the propellors, the more electricity we can make.

It's only worth building wind farms in places that have strong, steady winds, although boats and caravans increasingly have small wind generators to help keep their batteries charged.



  • Wind is free, wind farms need no fuel.

  • Produces no waste or greenhouse gases.

  • The land beneath can usually still be used for farming.

  • Wind farms can be tourist attractions.

  • A good method of supplying energy to remote areas.



  • The wind is not always predictable - some days have no wind.

  • Suitable areas for wind farms are often near the coast, where land is expensive.

  • Some people feel that covering the landscape with these towers is unsightly.

  • Can kill birds - migrating flocks tend to like strong winds. Splat!

  • Can affect television reception if you live nearby.

  • Can be noisy. Wind generators have a reputation for making a constant, low, "swooshing" noise day and night, which can drive you nuts. An entire wind farm makes quite a racket!
    Having said that, the small modern wind generators used on boats and caravans make hardly any noise, and as aerodynamic designs have improved, modern wind farms are much quieter.


It is renewable?

Wind power is renewable . Winds will keep on blowing, it makes sense to use them.
