This is not some distant vision for America. The transition away from fossil fuels is going to take some time, but over the last year and a half, we've already taken unprecedented action to jumpstart the clean energy industry. As we speak, old factories are reopening to produce wind turbines, people are going back to work installing energy-efficient windows, and small businesses are making solar panels. Consumers are buying more efficient cars and trucks, and families are making their homes more energy-efficient. Scientists and researchers are discovering clean energy technologies that someday will lead to entire new industries.
