After reviewing the horrors of global warming, McKibben reports how the U.S. and other nations could deploy renewable energy rapidly enough to reduce fossil fuel emissions 80% by 2030. Using a wholesale industrial retooling akin to WWII to manufacture solar, wind and geothermal equipment, the reconstruction would be ordered and partly paid for by the feds, using existing contracts as leverage to force businesses to comply.
