Ed Begley Jr. is not just another cause celeb -- he's been a vocal environmental activist for more than 30 years, almost as long as he's been an actor.

After two seasons on HGTV, his eco-friendly reality series 'Living With Ed' is moving to its new channel, Planet Green (season 3 premieres Wed., Oct. 21, 9PM ET). With reusable bags being the latest must-have accessory and the bad economy forcing people to conserve their cash, going green is not just cool -- it's a way of life.

We caught up with Ed to get the dish on his show's new green home, his latest planet-saving endeavors and what we can all be doing to be more eco-conscious. -- By Maggie Furlong

It's just good common sense. You get yourself a big time show (Entourage) on a big network (HBO) and then you jump on board with a huge star (Ed Begley Jr?). I'm sure it made more sense in the pitch meeting. Anyway, Entourage star Grenier has a new gig that will be airing on the soon to launch Planet Green channel.

His new show, Alter Eco, will follow his Green Team as they take on environmental projects around Los Angeles. The team includes Boise Thomas, model Angela Lindvall, and Darren Moore. Moore is listed in the linked article as a renovations expert, but I just think of him as the physicist from Twitch City, which is cool enough to get me to tune in at least once. Planet Green, which will also be the home of Begley Jr's Living With Ed, is set to launch on June 4th, with the 13 episode run of Alter Eco premiering June 9th.

(S01E01) Ed Begley, Jr. loves the environment. In fact, his love for Mother Earth often overshadows his acting career, and after watching HGTV's sneak preview of the new reality series Living with Ed, you get the feeling he's just fine with that.

The new series, which slips into its regular timeslot of Sundays at 10pm starting January 7, follows Ed and his wife Rachelle, who suffers her husbands tenacity with light sarcasm and good humor. She sums up her predicament quite well when she says, "I married into a lifestyle."

The "lifestyle" is one in which her husband cooks on a solar grill, hoses "smog dust" off the solar panels on his roof, times her while she's in the shower, and drives an electric car to the Academy Awards. Rachelle is not always happy with Ed valuing environment over aesthetics, complaining that he always picks out the ugliest environmentally-friendly things he can find. Whether Begley's lifestyle is overkill or not, I can't help but admire a man who actually practices what he preaches.

Add Ed Begley Jr. to the ever-growing list of Hollywood stars with their own reality series. The former St. Elsewhere star, and current obsessed eco-nut committed environmentalist will be starring with wife and actress Rachelle Carson in a new series for HGTV called Living With Ed.

According to our friends at sister site AutoblogGreen, the new show (which premieres January 7th at 10:00 pm) will be set in the couple's entirely solar-powered, eco-friendly home. You'll be able to watch as Ed times his wife's shower with a stopwatch while gently chiding her over how many gallons of water she has wasted. You'll also be able to see how Begley rides a stationary bike in order to power his toaster. He will also be giving tips to the viewers on how to make their living areas more environmentally safe and energy efficient.
