David Attenborough: Here’s my world-changing idea!

David Attenborough thinks that cheap solar energy should be imperative. The iconic natural history presenter described his ideal technological revolution:  “Supposing that those people who had invented the steam engine and so on had, in fact, turned their thoughts on how to use energy and heat from the Sun – that could have changed history. We would no longer have to fell forest, we would no longer have to take oil over vast areas of land that have been completely destroyed. Above all we would no longer have polluted the atmosphere,” he says. “If we get cheap energy which doesn’t pollute, then we are into a golden age.”
