Columnist and best-selling author Thomas Friedman doesn't support cap-and-trade legislation merely because of climate-change concerns. Friedman sees it as key to keeping us from being "laggards in the next great global industry." Friedman wrote that China is already focusing on energy efficiency and clean power systems. "And when China starts to do that in a big way _ when it starts to develop solar, wind, batteries, nuclear and energy efficiency technologies on its low-cost platform _ watch out," Friedman said. "You won't just be buying your toys from China. You'll be buying your energy future from China."
