How did they get Gore's utility bill? According to a spokesperson (link):
Gore spokeswoman Kalee Kreider said: "Sometimes when people don't like the message, in this case that global warming is real, it's convenient to attack the messenger."
Kreider said Gore purchases enough energy from renewable energy sources such as solar, wind and methane gas to balance 100 percent of his electricity costs.
Gore, who owns homes in Carthage, Tenn., and in the Washington area, has said he leads a "carbon-neutral lifestyle." To balance out other carbon emissions, the Gores invest money in projects to reduce energy consumption, Kreider said.
Also, Gore's house is 10,000 square feet. In the article, they compare his house with the average house in Nashville, but they don't say the size of the average house in Nashville (1500 sq. ft.? 2000 sq.ft.?). They don't indicate that the Gore family has a contingent of Secret Service agents within their home. There are also other buildings on their property.
We need to face the fact that this "research" group is just a bunch of right wing nuts who don't believe in science and they don't want to respect someone like Al Gore.
