Physics of the Future: How Science Will Shape Human Destiny And Our Daily Lives By the Year 2100
“Worldwide, generating capacity from wind grew from 17 billion watts in 2000 to 121 billion watts in 2008. Wind power, once considered a minor player, is becoming increasingly prominent. Recent advances in wind turbine technology have increased the efficiency and productivity of wind farms, which are one of the fastest-growing sectors of the energy market.
The wind farms of today are a far cry from the old windmills that used to power farms and mills in the late 1800s. Nonpolluting and safe,... a single wind power generator can produce 5 megawatts of power, enough for a small village. A wind turbine has huge, sleek blades, about 100 feet long, that turn with almost no friction. Wind turbines create electricity in the same way as hydroelectric dams and bicycle generators. The rotating motion spins a magnet inside a coil. The spinning magnetic field pushes electrons inside the coil, creating a net current of electricity. A large wind farm, consisting of 100 windmills, can produce 500 megawatts, comparable to the 1,000 megawatts produced by a single coal-burning or nuclear power plant.MoreLess
