While we may have had the weekend to try to digest the House's passage (by a close vote of 219-212) of the American Clean Energy and Security Act, I find there's still no consensus on what it means for the U.S. It's not just because it is hard to extract saliency from the 1200 pages that make up the bill, but rather because it's virtually impossible to understand what form the bill will ulitimately take if (and that's a potentially sizeable if) it gets through the Senate. (You may fondly remember the catchy Schoolhouse Rock song "I'm just a bill"). Read more.
