Wind turbines are a way of harnessing alternative energy, namely wind. The sight of large wind turbine "farms" is an increasingly common sight around the world. While mostly positive, wind turbines are not without their negatives.

Wind power is a 100 per cent clean, renewable and independent source of energy.

Expansion Potential

Estimates indicate that if the wind energy of the world was fully exploited, it would create five times the amount of electricity currently consumed globally.

High Starting Cost

According to the U.S. Deptartment of Energy, wind power costs £36.10 per MWH (megawatt hour); coal energy costs £34.50 per MWH; nuclear power £38.50 per MWH; natural gas £34.10 per MWH. This high price tag is due to the high initial capital costs, and it takes many years before a wind turbine starts paying for itself.


Not every location is suitable for a wind turbine. Only select locations--called "wind corridors"--have sufficient wind blowing regularly enough to make erecting the turbines worthwhile.


Wind turbines are considered unsightly, especially in rural landscapes that attract tourism.
