...sitting here on Capitol Hill. The clock is ticking while the American Clean Energy Leadership Act (ACELA) sits in a Senate committee. If you're not a policy wonk (political nerd) the US Senate must vote on this bill before April 16, 2010 or it expires. Apparently, some Senators are willing to let the bill die. If you are concerned about reducing CO2 emissions nationally and growing renewable energy, then it's time to call or write your Senator.
