This is the great challenge facing us as a country. If we're going to meet those goals, we may have to double our electricity production in the next decade. Our great challenge is we have to do what's taken us 100 years to get to this point in only 10 years and do it cleaner and cheaper than ever before. This is our mission. This is our generation's great movement, our great moment. With the economic stimulus, it's how we can grow those clean, sustainable jobs and grow a richer, more prosperous economy.
