White House goes green

Solar panels will be installed on the White House roof a quarter of a century after they were removed by President Ronald Reagan. A mix of different panels will be fitted in spring 2011 to generate both hot water and renewable electricity. The move will come as a surprise to many green campaigners after the White House rejected a recent request by environmentalists to install the technology.

It will be the first time since 1986 that solar panels have sat on the White House, since Reagan removed a system installed by his predecessor Jimmy Carter. In 1979 Carter held a conference on the roof, showing off the 32 panels and his desire to reduce the US's dependence on oil.

The return of solar at the White House follows other symbolic green efforts since Obama took power, including Michelle Obama’s creation of an organic vegetable garden in the White House grounds last year. Green campaigners have been lobbying the president to reinstate solar at the White House. They have been driving around the US in a biodiesel-powered van with one of the original panels installed by Carter. The campaigners visited the White House in September and made a symbolic demand for the old panel to be reinstalled on the roof. But the request was rejected and no plans for future solar panels were given.

Billy McKibben, who led the campaign, welcomed Obama's decision to fit new panels: "Solar panels on one house, even this house, won't save the climate, of course. But they’re a powerful symbol to the whole nation about where the future lies."

To mark climate events around the world, the president of the Maldives also decided to harness solar energy. Mohamed Nasheed, whose low lying island country is at risk from rising sea levels caused by global warming, has installed 50 panels on his presidential home.
