Peter Schweizer, a research fellow at the Hoover Institution and author of "Do As I Say (Not As I Do): Profiles in Liberal Hypocrisy," says Al Gore is simply not living the same lifestyle he asks others to live in his latest movie, "An Inconvenient Truth."

In an article for USA Today, Schweizer writes, "if Al Gore is the world's role model for ecology, the planet is doomed. For someone who says the sky is falling, he does very little."

"Public records reveal that as Gore lectures Americans on excessive consumption, he and 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."

Schweizer adds, "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... But according to public records, there is no evidence that Gore has signed up to use green energy in either of his large residences. When contacted recently, Gore's office confirmed as much but said the Gores were looking into making the switch at both homes."

"Gore has held these apocalyptic views about the environment for some time. So why, then, didn't Gore dump his family's large stock holdings in Occidental Petroleum? As executor of his family's trust, over the years Gore has controlled hundreds of thousands of dollars in Oxy stock."
