Al and Tipper Gore's home, a 1915 antebellum-style mansion in the wealthy Belle Meade section of Nashville, is laid out a bit like Gore himself: a gracious and formal Southern façade; slightly stuffy rooms when you walk in the door; and startlingly modern, relaxed, informal living spaces to the rear. The Gores bought the old place five years ago and are still retrofitting it, making it energy efficient with new windows, new heating and cooling units, solar panels on the roof. (The anti-Gore crowd zinged him recently because his electricity bill last August was 10 times the local average. The Gores pay extra to get 100% of their power from renewable sources, and their zealous retrofitting will no doubt bring their costs down. But it stung.)
