The Wind Future

Wind power is already practical in many places like Denmark, where 17 percent of the electricity comes from wind turbines. The newest turbines, with propellers as wide in diameter as a football field, produce energy at a cost of 4 or 5 cents a kilowatt-hour. Further refinements like lighter rotors could drop the price by another cent or two, making it directly competitive with natural gas.
