Wind Could Power 20 Percent of US Grid by 2030

A new report from the Department of Energy claims that wind turbines could generate 300 gigawatts by 2030, which would power about 20 percent of the US electrical grid.

The forecasting scenario would require tremendous growth in the wind industry, which currently produces about 17 gigawatts of electricity, or a little over one percent of total capacity.

All by itself, such a change could reduce carbon dioxide emissions from electricity generation (think: coal and natural gas plants) by 25 percent and drop water consumption by four trillion gallons. These benefits could be achieved at a cost of about six bucks per person a year, say the report's authors.

"To dramatically reduce greenhouse gas emissions and enhance our energy security, clean power generation at the gigawatt-scale will be necessary, and will require us to take a comprehensive approach to scaling renewable wind power," said Andy Karsner, the DOE's assistant secretary of energy efficiency and renewable energy in a release.

Currently, fossil fuels generate 85 percent of American energy, and about 70 percent of our electricity. Renewables (outside hydroelectric dams) are only responsible for a couple percent of our current electricity capacity. However, wind power has been expanding rapidly, growing 45 percent in 2007, as its cost has become competitive with traditional fossil fuel sources... blog.wired.com
