http://www.smh.com.au/news/world/gores-mansion-uses-too-much-power/2007/02/28/1172338670663.html Al Gore, a leading voice in the fight against global warming, is being called a hypocrite by a conservative group that claims his Nashville mansion uses too much electricity. But a spokeswoman for Gore said the former vice president invests in enough renewable energy to make up for the home's power consumption. Gore's documentary film An Inconvenient Truth won an Oscar on Sunday for chronicling his campaign against global warming. The next day, the Tennessee Centre for Policy Research put out a news release saying Gore was not doing enough to reduce his own consumption of electricity. "We wanted to see if he was living by his own recommendations and walking the walk," said Drew Johnson, president of the think tank that pushes for conservative economic issues. Utility records show the Gore family paid an average monthly electric bill of about $US1200 ($A1525) last year for its 929-square-metre home. The Gores used about 191,000 kilowatt-hours in 2006, according to bills reviewed by The Associated Press spanning the period from February 3, 2006, to January 5. That is far more than the typical Nashville household, which uses about 15,600 kilowatt-hours per year. A spokeswoman for Gore said he purchases enough "green power" - renewable energy sources such as solar, wind and methane gas - to balance 100 per cent of his electricity costs. "Sometimes when people don't like the message, in this case that global warming is real, it's convenient to attack the messenger," Gore spokeswoman Kalee Kreider said.
