Over the last few years, wind power in the U.S. has been increasing rapidly. In 2010, however, new construction was about half of the previous year due to various factors, including the financial crisis, and recession. The graph at left shows the growth in installed wind generation capacity in the United States based on data from the Office of Energy Efficiency and Renewable Energy. In 2008, installed capacity in the U.S. increased by 50% over the prior year. The world average growth rate that year was 28.8%.
New wind farms can produce electricity in the 5-8 cents per kWh range, making wind power competitive with the cost of fossil fuel electricity generation in many markets. Fifteen states have each installed over 1,000 MW of wind capacity, and a total of 39 states and Puerto Rico now have installed at least some utility-scale wind power. Much of the new wind power capacity is being built in the Great Plains and Midwest regions of the United States, which have a favorable combination of characteristics: ample wind resources, an extensive rail and highway network for shipping outsized turbine components, flat topography which both improves the wind and makes turbine components easier to ship, and broad acceptance from local farmers and ranchers. New development in some locations, however, is being limited by lack of additional capacity to transmit power to locations where it can be used.

Famous quotes containing the words national and/or trends:
“I foresee the time when the painter will paint that scene, no longer going to Rome for a subject; the poet will sing it; the historian record it; and, with the Landing of the Pilgrims and the Declaration of Independence, it will be the ornament of some future national gallery, when at least the present form of slavery shall be no more here. We shall then be at liberty to weep for Captain Brown. Then, and not till then, we will take our revenge.”
—Henry David Thoreau (1817–1862)
“A point has been reached where the peoples of the Americas must take cognizance of growing ill-will, of marked trends toward aggression, of increasing armaments, of shortening tempers—a situation which has in it many of the elements that lead to the tragedy of general war.... Peace is threatened by those who seek selfish power.”
—Franklin D. Roosevelt (1882–1945)
