摘要

Wind power is booming,largely due to a search for energy from sources other than fossil fuels,such as petroleum and coal.Much of today's wind power comes from big "farms" that have many tall,modem windmills,called wind turbines.These machines have long shafts.In some designs,they can reach taller than a l0-story building.These shafts are topped by giant blades.These connect to a generator that converts the energy of their spinning motion into electricity.
