Public records reveal that as Gore lectures Americans on excessive consumption, he and his wife Tipper live in two properties: a 10,000-square-foot, 20-room, eight-bathroom home in Nashville, and a 4,000-square-foot home in Arlington, Va. (He also has a third home in Carthage, Tenn.) For someone rallying the planet to pursue a path of extreme personal sacrifice, Gore requires little from himself.

Then there is the troubling matter of his energy use. In the Washington, D.C., area, utility companies offer wind energy as an alternative to traditional energy. In Nashville, similar programs exist. Utility customers must simply pay a few extra pennies per kilowatt hour, and they can continue living their carbon-neutral lifestyles knowing that they are supporting wind energy. Plenty of businesses and institutions have signed up. Even the Bush administration is using green energy for some federal office buildings, as are thousands of area residents.

But according to public records, there is no evidence that Gore has signed up to use green energy in either of his large residences.
