4.0版第18篇 electricity from wind
Since 1980,the use of wind to produce electricity has been growing rapidly.
█In 1994 there were nearly 20,000 wind turbines worldwide,most grouped in clusters called
wind farms that collectively produced 3,000 megawatts of electricity.█Most were in
Denmark (which got 3 percent of its electricity from wind turbines) and California (where
17,000 machines produced 1 percent of the state’s electricity,enough to meet the residential
needs of a city as large as San Francisco).█In principle,all the power needs of the United
States could be provided by exploiting the wind potential of just three states—North Dakota,
South Dakota,and Texas.█
