SMH - Anti-poverty campaigner Bob Geldof joined the global warming debate today with a call for the rapid expansion of nuclear power, describing renewable energy as a "Mickey Mouse" answer to the climate crisis. "The reality is that we need to do much more than change the type of car we drive to make an impact on climate change. In the UK, we'll soon have to scramble for more nuclear power," Geldof wrote. "On this issue, I don't care what anyone says: we're going to go with it, big-time. We may mess around with wind and waves and other renewable energy sources, trying to make them sustainable, but they're not. They're Mickey Mouse," he said.
