How is wind created?
Uneven heating of the Earth’s surface by the sun causes the wind. The warmer air in some places rises. The resulting low pressure area draws in cooler air.
Wind patterns are affected by the spin of the planet, weather patterns, and terrain.
Wind energy potential increases very rapidly with increasing wind speed. If fact, if wind speed doubles the energy content goes up by a factor of eight.

The future of large wind systems.
Large wind turbines have gotten much bigger and much less expensive in the last 15 years. They can already produce electricity less expensively than power from coal or nuclear power plants. Some experts expect large wind turbines to be the least expensive way to produce electricity within ten years.
