Al Gore, the environmental activist stung by criticism over his house’s energy efficiency, says renovations are nearly complete to make it a model “green” home.

“This plan has been in the works for a long time,” the former vice president said in an interview Friday with The Associated Press. “The only thing that has changed is that we’re more public about it because of the misleading attack by a global-warming denier group.”

Earlier this year, a conservative group criticized Gore, citing electric bills that were far more than the typical Nashville home. Utility records showed that the Gore family paid an average monthly electric bill of about $1,200 last year for its 10,000-square-foot home.

Still, nice to see that he’s catching up with the environmental pioneers. Of course, the EcoTotality blog was on this story from months ago.

UPDATE: EcoTotality also had this economic analysis of what Gore’s doing. Conclusion: “Economically, Gore’s solar panels are a bad investment. . . . Politically, though, Gore pretty much has to put the solar panels on his roof.”
