The Energy Independence and Security Act bill has officially been signed into law -- the same document that calls for CAFE standards increased to 35 mpg by 2020. The bill stalled twice in the Senate -- once by seven votes and the last by one -- but the proposal passed on its third try and was once again approved by the House yesterday.

According to Automotive News, Senate Republicans objected mainly to tax provisions and a requirement that utilities use more renewable fuels, delaying the bill twice. Those provisions were trimmed, allowing the bill to pass.

President Bush signed the bill earlier today.

The new CAFE standards will be phased in beginning in 2011 -- representing the first changes to the CAFE standards since its inception in 1975.
