Gore and the Monster House

First we hear this...

The average household in America consumes 10,656 kilowatt-hours (kWh) per year, according to the Department of Energy. In 2006, Gore devoured nearly 221,000 kWh—more than 20 times the national average.

Last August alone, Gore burned through 22,619 kWh—guzzling more than twice the electricity in one month than an average American family uses in an entire year. As a result of his energy consumption, Gore’s average monthly electric bill topped $1,359.

Since the release of An Inconvenient Truth, Gore’s energy consumption has increased from an average of 16,200 kWh per month in 2005, to 18,400 kWh per month in 2006.

Gore’s extravagant energy use does not stop at his electric bill. Natural gas bills for Gore’s mansion and guest house averaged $1,080 per month last year.

In total, Gore paid nearly $30,000 in combined electricity and natural gas bills for his Nashville estate in 2006.

Then the response from the Gore camp...

1) Gore's family has taken numerous steps to reduce the carbon footprint of their private residence, including signing up for 100 percent green power through Green Power Switch, installing solar panels, and using compact fluorescent bulbs and other energy saving technology.

So they have taken all these energy saving measures and he still has a yearly power bill of $30,000.
What is he doing in there? Smelting aluminum ?
