  • The U.S. has had modern, commercial-scale wind power for more than two decades. The first domestic wind farms were constructed in California in the early 1980s.  The U.S. wind industry reached its first 1,000 megawatts of installed capacity in 1985, but then took more than a decade to reach 2,000 megawatts in 1999.  Since 1999, however, the installed capacity has increased fivefold.  Today, wind energy is the nation's fastest growing source of commercial-scale power.

shared by wellsann99 on 12 Mar 13 - No Cached
  • In 1997, U.S. power plants emitted 70% of the sulfur dioxide, 34% of carbon dioxide, 33% of nitrogen oxides, 28% of particulate matter and 23% of toxic heavy metals released into our nation's environment, mostly the air. These figures are currently increasing in spite of efforts to roll back air pollution through the federal Clean Air Act.

  • Over 8,500 MW were installed in the US in 2008 (just beating out China with 6,300 MW). This represents: 50 percent increase from 200742 percent of all new generating capacity installed in 2008$17 billion investment44 million tons of carbon emissions avoided (equivalent of 7 million cars)35,000 new jobs

How does wind generate electricity? - Curiosity - 1 views

  • the wind turbine collects kinetic energy from the wind and transfers it to the generator. The blades on the turbine turn as the wind blows. As these blades move, they rotate a shaft connected to the rotor of a generator. The spinning magnets of the generator convert that rotational energy into electricity.

  • STEP 1: Moving air pushes against the blades of the turbine, which are tilted to the direction of the wind. This makes the blades spin. In the process, some of the kinetic energy of the moving air is transformed into the mechanical energy of the spinning blades. (The wind still has some kinetic energy as it flows away from the turbine.) STEP 2: The shafts and the gears inside the gear box transfer the mechanical energy of the turbine to the generator. (The gears make the drive shaft to the generator spin faster than the shaft connected to the blade hub.) STEP 3: The generator transforms mechanical energy into electrical energy.

  • Most of the wind energy produced  for power needs comes from wind farms, great big windmill type contraptions produce electricity because as the wind blows it turns the blades on a shaft, which powers a generator.
