Wind farms are also getting bigger. The largest wind farm in North America, Alta Wind Energy Center in California, which is the third largest in the world, will be small in comparison with the proposed 3-GW Chokecherry-Sierra Madre Wind Project in the U.S. or the proposed expansion of China’s 6-GW Gansu wind farm to a staggering 20-GW by 2020.The average cost of a small roof-mounted turbine (between 0.5 kW to 2.5 kW), is about £2,000 5. But these don’t generate very much electricity, so it will take a very long time to recoup that cost. On average, a free-standing 5kW wind turbine may cost between £20,000 and £25,000.Wind energy is created when moving air causes a wind turbine to rotate, powering a motor that generates electricity.
