2. There is evidence that wind energy was used to propel boats along the Nile as early as 5000BC. The earliest known windmills were in Persia (Iran) and looked like large paddle wheels. In 200BC people in China and the Middle East used windmills to pump water and grind grain. The largest wind turbine in the world is in Hawaii. It stands 20 storeys high and has rotors the length of a football field. The UK is the windiest country in Europe, so much so that we could power the whole country several times over using wind energy. Wind is the fastest growing energy source worldwide. An average wind speed of 14mph is required to convert wind energy into electricity. FACTS

4. Wind energy system operations don't generate air or water emissions and don't produce dangerous waste. and they don't ruin natural resources such as coal, oil, or gas, or cause environmental damage through getting the oil and coal and transportation isn't a problem. Wind's pollution-free electricity can help reduce the environmental damage caused by fuel users worldwide.
