If the power being generated by the 10,000 MW of wind power installed in the U.S. were being generated by the conventional U.S. generation mix . . .
Although 10,000 MW is an important milestone, wind power provides a small share of the nation’s electricity. The Energy Information Agency reports that 985,285 MW of all kinds of generating capacity is installed in the U.S. Today, we are providing less than 1% of the nation’s power. However, wind power is one of the fastest-growing electricity sources today, and can be expected to be an important source of our power needs in the future. The U.S. first started installing electricity-generating wind power in the early 1980s. The country had 1,000 MW of wind power installed by 1985; 2,000 MW installed by 1999; and 5,000 MW by 2003. The only other countries around the world that have more wind power installed are Germany (19,140 MW as of the end of June), and Spain (10,728 MW). AWEA expects the U.S. to pass the 15,000 MW mark by the end of 2007 and can have 25,000 MW installed by the end of 2010, with the proper policies in place. At this growth rate, the U.S. could have 100,000 MW installed by 2020, which would provide the nation with approximately 6% of its future power needs, about as much as hydropower provides today. The more wind power, the better for our energy security. Wind power is an inexhaustible, domestic energy source that can be tapped on a large scale: America’s wind resource potential is vast--theoretically more than twice enough to meet current U.S. electricity supply. President Bush said earlier this year that wind could meet 20% of the country’s electricity supply. If wind power were providing 20% of our nation's power today . . .

Assumptions: - 31% average capacity factor assumed for entire turbine fleet. - Average annual household consumption ( U.S.) = 10,656 kWh. - A plug-in hybrid car can travel 4 miles per kWh. - To generate the same amount of electricity as a single 1-MW wind turbine using either fossil fuels or nuclear power requires, on average, withdrawing roughly 60 million gallons of water a year from streams, rivers, or aquifers, of which nearly 1 million gallons is lost to evaporation; generating the same amount with hydropower means the loss of approximately 50 million gallons a year to evaporation. - Due to national regulation on SO2, there is a cap on how much would have been emitted, but the costs for adhering to the cap would have been higher. |
