Windpower: Renewable Wind Energy

Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines.

Although wind currently produces about 1% of world-wide electricity use,it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data).

Advantages

  • Wind is free, wind farms need no fuel.
  • Produces no waste or greenhouse gases.
  • The land beneath can usually still be used for farming.
  • A good method of supplying energy to remote areas

Wind Turbine, Windpower: Renewable Wind Energy
Disadvantages

  • 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.
  • Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.
  • Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at.
  • They disfigure the countryside and are generally ugly.
    When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution.
