Wind Power

We've used the wind as an energy source for a long time.

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.

Advantages of Wind Energy:

In this day and age, the world needs to look at the different natural energy sources available to us. Global warming could be due our energy craving lifestyle, so we should look into more environmentally friendly energy sources.

  • Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy.
  • Wind turbines take up less space than the average power station. Windmills only have to occupy a few square meters for the base, this allows the land around the turbine to be used for many purposes, for example agriculture.
  • Newer technologies are making the extraction of wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy.
  • Wind turbines are a great resource to generate energy in remote locations, such as mountain communities and remote countryside. Wind turbines can be a range of different sizes in order to support varying population levels.
