Addressing global climate change requires clean energy technologies that are cost- and performance competitive with fossil fuels without subsidies. Characterized by carbon prices, subsidies, and mandates, the dominant clean energy policy approaches in the United States and internationally are not likely to meet this goal. Only a cohesive and aggressive innovation strategy can produce the needed and rapid development of affordable clean energy options the entire world wants to purchase.
The United States ranks as among the world's top countries in clean tech investments, patents, renewable energy generation and electric vehicle (EV) adoption. At the same time it is among the world's worst for energy consumption and emissions. Over the last two decades, however, the U.S. has become more energy productive, using less energy per dollar of GDP generated.

In the "Wind Vision" report, the Department of Energy projects that the country could do even more going forward by installing up to 11 gigawatts of new wind-generating capacity each year between now and the middle of the century. That would bring the U.S. to 400 total gigawatts of such capacity installed across the country -- enough power for 100 million homes, according to the Energy Department's estimates.
The DOE outlines a path to 35 percent, beginning with 10 percent by 2020 and rising to 20 percent by 2030.
