Here is some good news. Researchers at Stanford have worked out what it really would take to convert from carbon to noncarbon energy. It can be done, and it is clear it is now no longer a matter of technology but of political will, and America's willingness to choose wellness over profit for the few. It will be cheaper, more efficient, productive of tens of thousands of jobs while, at the same time tens of thousands of lives in the U.S. alone would be saved. And it could happen by 2050.
