In 2002, the following amount of electricity, in gigawatt-hours, was generated from the following sources of fuel:
Coal: 1,925,792 GWh
Nuclear: 779,461 GWh
Gas: 695,226 GWh
Hydro: 255,077 GWh

The U.S. Department of Energy expects wind power to supply at least five percent of the nation's electricity by 2020.
In 1990 in California alone, wind power offset the emission of more than 2.5 billion pounds of carbon dioxide and 15 million pounds of other pollutants - the same amount of air quality provided by more than 150 million trees.
Technological innovations have brought the cost of wind power down from more than 30 cents per kilowatt-hour during the 1980s to less than six cents per kilowatt-hour today.
Because the Moon has no wind or water to erode them, the footprints left by Apollo astronauts could last for millions of years.
The Wright brothers built their own wind tunnel in 1901 to test hundreds of wing shapes, collecting data that was more accurate than what scientists had at the time.

The Golden Gate Bridge is designed to sway up to about 27 feet in strong winds.
After new railings were installed in 2020, the Golden Gate Bridge started making a humming sound in strong winds.
Neptune has the strongest winds in the solar system, up to about 1,200 miles per hour.
The Wright brothers built their own wind tunnel in 1901 and tested about 200 wing shapes to fix errors in existing aerodynamic data.
