As the world beats a path to Copenhagen for the December 2009 UN meeting to craft a new deal on climate change solutions, one of the biggest challenges remains our addiction to oil. About 40% of global greenhouse gases come from oil, when you include exploration, development, refining, transportation, and combusting it. A few years ago, the US government hailed corn-based ethanol as the alternative/savior, but when food prices skyrocketed because of a misguided policy to subsidize farmers (and when science showed the greenhouse gas benefits were small or non-existent), the rush was on to find another magic bullet.

Now the US government, led by Energy Secretary Steve Chu, has put on their Don Quixote armor again and is pouring lots of taxpayer dollars into batteries for cars. While I am the first to say there will be no silver bullet, only silver buckshot - - we need ALL alternatives to oil - - it's time to dump the battery-powered car in the same policy landfill as corn-based ethanol.
