What's in a number? June 30, 2009 : 10:02 AM

As the American Clean Energy and Security Act was debated in the House, it seemed as though some members of the chamber were throwing out random numbers when referring to the cost of the bill. As the legislation moves to the Senate, this is an important fact to address. The most commonly cited number from those who oppose this legislation was to claim the cost would be "more than $3,000 a year.”

Here are the facts. According to the nonpartisan and widely respected FactCheck.org, “The $3,100 figure is a misrepresentation of both Obama's proposal and the study from which the number is derived.”

In Washington, the CBO is considered one of the best sources for the cost of legislation. They wrote: "On that basis, the Congressional Budget Office (CBO) estimates that the net annual economy wide cost of the cap-and-trade program in 2020 would be $22 billion-or about $175 per household."

That works out to approximately the cost of a postage stamp a day.
