Celebrities off the Grid, off the Meat, and on the Money

Between promoting the much-anticipated release of the Sex & the City movie, Kristin Davis told David Letterman last week all about her solar-powered house and her work in Africa with Oxfam. The actress, aka “Charlotte,” enthusiastically described watching her electric meter spin backwards, and because the system stores power in batteries, she’s prepared if the lights go out.

The finale for the upcoming Planet Green’s series, Battleground Earth: Ludacris vs. Tommy Lee, tapes this week at LA’s Greek Theater in Griffith Park to benefit the area destroyed by last year’s nearby wildfires. Concert performances include Tommy Lee and Ludacris (of course), Blue Man Group, and Billy Gibbons of ZZ Top, plus more. The show features the metalhead and rapper locked in an unlikely carbon footprint combat.

Shawn Colvin performed at Farm Sanctuary’s fundraiser last week in New York, which lured a gaggle of celebs supporting the organization for farm animal protection. Melissa Rivers (Joan’s daughter) emceed, Heather Mills hosted, and attendees included comic actor/author Kevin Nealon, hip-hop entrepreneur Russell Simmons, pop artist Peter Max, and Rep. Dennis Kucinich, reportedly the only vegan member of Congress, who’s investigating the California meat plant recently caught processing downer cows…Oprah recently announced she’s gone vegan, too. Will she convert America?

At the Audubon Society’s annual Women in Conservation luncheon at The Plaza last Tuesday, Bette Midler received the Rachel Carson Award for her efforts as founder of the New York Restoration Project which has created 57 community gardens in Manhattan, rescued a 5-acre park in Harlem, and plans to plant a million trees in partnership with Mayor Bloomberg’s MillionTreesNYC. Gorillas in the Mist actress Sigourney Weaver emceed the event, which also honored Teresa Heinz Kerry of the Heinz Endowment and Family Philanthropies for efforts to improve environmental policy. She and her husband, Sen. John Kerry, wrote This Moment on Earth: Today’s New Environmentalists and Their Vision for the Future.

Midler’s annual Spring Picnic is auctioning great meet’n’greets until May 29 to benefit her causes. Bid on chances to hangout backstage with the singer/actress after her Vegas show, with Glenn Close on the set of Damages, or win a walk-on role on Comedy Central’s Sarah Silverman Program, which was going for just $2,750 at last look. So press-the-flesh with the stars, and contribute to the Big Apple’s tree plantings.
