Wind power 2014
The wind is a renewable energy source. Wind turbines can convert energy into electricity, then the human advantage. The wind power is very powerful.
The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h. Most wind farms in the UK are in Cornwall or Wales. Isolated places such as farms may have their own wind generators. In California, several "wind farms" supply electricity to homes around Los Angeles. The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming.
What is the effect of wind power?
- Wind is free
- doesnt produce any wastes
- The land where the wind propelors are placed on, can usually still be used for farming.
- Wind farms can be tourist attractions.
- It is a good method of supplying energy to remote areas.
- The wind is not always predictable - some days there is no wind so theres no power
- areas for wind farms are often near the coast, where land is expensive.
- Some people think that placing these wind towers doesnt look nice.
- Can kill birds – because some birds like strong winds( but people dont tend to build them on the migration routes
- Can affect television reception if you live nearby.
- Can be noisy.
- People have found evidence of bird and bat deaths from the wind poles due to changes in air pressure caused by the spinning turbines, as well as habitat disruption.
