Larry Hagman stars in SolarWorld ad, 'Dallas' star calls for solar energy

Larry Hagman, who played Texas oil tycoon J.R. Ewing in the hit 1970s shows Dallas and also starred in I Dream of Jeannie, is calling for people to embrace solar technology as part of a new "Shine, Baby, Shine" ad campaign for solar panel manufacturer SolarWorld.

"In the past, it was always about the oil. The oil was flowing and so was money. I quit years ago but I'm still in the energy business. There's always a better alternative. Shine, baby, shine!" Hagman, 78, says in a commercial posted on the SolarWorld website, before cackling happily.

The ad shows him looking at a portrait of himself as Ewing, exiting his hillside estate in Ojai, California, where he lives with wife Maj, and looking up at a red roof containing a solar panel.

Hagman is a longtime advocate of renewable energy and owns one of the largest U.S. residential solar panel systems, which cost him $750,000 when he bought it in 2003. He says they reduced his annual power bill from $37,000 to $13.

Hagman has appeared on television sparingly in recent years and starred as recurring character Burt Landau in the series Nip/Tuck in 2006.
