The White House is going solar after all - a home improvement that carries modest energy benefits but much larger symbolic importance. It isn't the first time the White House has used solar energy. President Jimmy Carter put 32 solar panels on the roof in the late 1970s, but President Ronald Reagan removed them in 1986. Two grass-roots campaigns have recently been lobbying President Obama to restore them as a sign of his commitment to renewable energy. The roof of the White House residence will get solar panels and a solar water heater, Energy Secretary Steven Chu and the White House Council on Environmental Quality's chair, Nancy Sutley. A campaign launched by Oakland, Calif.-based Sungevity called Solar on the White House and another by 350.org founder Bill McKibben tried to get Obama to reinstall solar panels. "The White House did the right thing, and for the right reasons: They listened to the Americans who asked for solar on their roof, and they listened to the scientists and engineers who told them this is the path to the future," McKibben said in a statement. "If it has anything like the effect of the White House garden, it could be a trigger for a wave of solar installations across the country and around the world," he said.
