Al Gore's 'Inconvenient Truth'? -- A $30,000 Utility Bill

These efforts did little to impress Johnson. "I appreciate the solar panels," he said, "but he also has natural gas lanterns in his yard, a heated pool, and an electric gate. While I appreciate that he's switching out some light bulbs, he is not living the lifestyle that he advocates."

The Center claims that Nashville Electric Services records show the Gores in 2006 averaged a monthly electricity bill of $1,359 for using 18,414 kilowatt-hours, and $1,461 per month for using 16,200 kilowatt-hours in 2005. During that time, Nashville Gas Company billed the family an average of $536 a month for the main house and $544 for the pool house in 2006, and $640 for the main house and $525 for the pool house in 2005. That averages out to be $29,268 in gas and electric bills for the Gores in 2006, $31,512 in 2005.

The press release from Johnson's group, an obscure conservative think tank founded by Johnson in 2004 when he was 24, was given splashy attention on the highly-trafficked Drudge Report Monday evening, and former Gore aides saw it as part of a piece, along with an Fox News Channel investigation from earlier this month of Gore's use of private planes in 2000. Last year, a seemingly amateurish Youtube video mocking the "An Inconvenient Truth" turned out to have been produced by slick Republican public relations firm called DCI, which just happens to have oil giant Exxon as a client.

"Considering that he spends an overwhelming majority of his time advocating on behalf of and trying to affect change on this issue, it's not surprising that people who have a vested interest in protecting the status quo would go after him," said the former Gore aide.

Kreider says she's confident that the Gores' utility bills will decrease. "They bought an older home and they're in the process of upgrading the home," she said. "Unfortunately that means an increase in energy use in order to have an overall decrease in energy use down the road."

Gore is not the only environmentalist associated with "An Inconvenient Truth" who has come under fire for personal habits --
