Begley Vs. Nye: Who's Greener?

Keeping up with the Joneses takes on a whole new echelon of meaning when you're Ed Begley Jr. and your neighbor happens to be Bill Nye the Science Guy.

Nye, who moved onto the Living with Ed star's street a year ago, is "a very nice fellow who started this competition, I suppose, to see who could have the lowest carbon footprint," Begley tells ABC News.

"Without Ed down the street pushing all of us to live a more environmentally responsible lifestyle, I wouldn't be so motivated to crush him like a bug," says Nye, who has upped the ante in this backyard battle by installing his own state-of-the-art solar-power system.While Nye's racing to catch up by outlining an organic garden—the Begleys have been eating out of theirs for years—Nye says that his single status presents a key advantage when it comes to energy conservation.

"I have to be on the grid … a lot," Begley explains, "because of certain people here who don't have my certain zeal for exercising on the bike to produce power, or saving power."

"I've really taxed Ed's life haven't I? I've ruined it [with] a blow dryer!" jokes Begley's wife.

The latest standoff: Wind turbines. Nye came home one day and noticed a turbine installed on Begley's garage. So the Science Guy ordered his own—one that's even more efficient.

"Let's not get carried away," says Begley. "But we can show people they can still have a cool beverage and a warm shower. We're just going to do it more efficiently."

"You save money—what's not to love about that?" says Nye. ::ABC News
