Or build more wind and solar. Already Des Moines gets 80% of its power from wind, and the state is building more all the time. CA is doing some solar steps, but it is taking a lot longer (on a much larger population, so I'm not sure how their progress compares). Most states are not doing much. Europe is also making some steps, but they could do more.

The key to all this is starting ASAP and building constantly. Iowa has been building wind turbines at a rate of about 2/day (a bit over 500 per year) for many years now.
