The Advantages
of Wind Energy


As more wind farms are built, the
United States is beginning to get
closer to the goal set by the Department
of Energy of obtaining 20 percent of the
country’s energy supply from wind by the year
2030. It is clear that the benefi ts of wind power will touch
many areas of life.
One obvious benefi t is the environmental impact of not
relying as much on fossil fuels. If wind power produced 20
percent of U.S. electricity by the year 2030, carbon dioxide
emissions would be cut by 25 percent. The reduction in
emissions of gases linked to global warming would be equal
to removing 71 million cars from the roads or planting 104
million acres (42 million hectares) of trees. There would also
be an impact on water. Generating electricity using fossil fuels
takes a great deal of water, while making electricity with wind
power does not. An increase in wind-powered electricity would
decrease the amount of water required for the production of
electricity by 4 trillion gallons (15 trillion liters).
Cleaning up the environment is not the only benefi t to
choosing alternative energy sources such as wind power.
Coal, oil, and natural gas are being used up. New sources of
energy must be found. Together with other renewable sources,
such as solar energy, wind power can help provide energy for
