We've been using them for hundreds of years and whilst the design and science behind them may have changed significantly the main basic principle of the windmill remains the same, but how does wind energy work and how can it generate electricity?
Well, it's actually quite straight forward, the wind blows the sails or blades around which turns a series of rotors inside the head of the turbine which then rotate fast enough to generate power.
Wind energy is clean, very cheap to create, but it's one main downside is the lack of consistency. There are no guarantees that wind will be available to turn the turbines in order to generate energy.
So if you've ever been sat there and wondered to yourself 'how does wind energy work, you should go and take a look at this page for a much better and fuller description.
