Big Oil Lets Sun Set on Renewables

Shell, the oil company that recently trumpeted its commitment to a low carbon future by signing a pre-Bali conference communique, has quietly sold off most of its solar business.

The move, taken with rival BP's decision last week to invest in the world's dirtiest oil production in Canada's tar sands, indicates that Big Oil might be giving up its flirtation with renewables and going back to its roots.

Shell and BP are among the biggest producers of greenhouse gases in the world, but both have been keen to paint themselves green through a series of clean fuel initiatives.
