Wind Power.

Extracts from this document...

Introduction

This is a project on wind power. Wind is a renewable source of power with potential in the production of electricity in the U.K, but fluctuating wind currents make it unreliable. We asked ourselves how it works and what it does.

Wind Turbines

Wind turbines are very useful and are powered by the wind. The process of collecting the energy follows: as the wind turns the blades then the blades activate the dynamo inside that really makes the electricity. As you can imagine a field of dynamos all going as fast as they can would be very noisy. As we all

The drawbacks of TIDAL and WAVE power are that the alter of the tidal currents affect the habitat of the seabirds in the area also the fish are affected by the change in the tidal currents. Also the tidal and wave power stations can only produce ten hours of power in one day of twenty-four hours so they would have to generate the other fourteen hours of power another way which may be quite expensive. But there are also good points about tidal and wave power. One good point is that the power produced is cheap.

Conclusion

Example - The wind speed is 50km, the time is 30 hours and it's open sea, the waves will be 6m high. Waves resulting from local winds and travelling from local distance will not develop to their full height. Example - Dover and France are 40km apart so these waves are Sea Waves. This is an insufficient distance for the wind to develop waves to their full height. Waves formed by winds blowing over large distances are called Swell Waves. The length of open sea over which the wind blows to generate waves is the Fetch. This along with velocity and period of time during which the wind has blown determines the waves energy.
