Solar ‘cheapest electricity in history’

Quick announcement by the IEA–solar energy is now the cheapest energy in history. The announcement certainly marks a significant turn for the IEA. But it will probably not come as a surprise to those of you who have watched solar power mature. I think the trajectory was there for a number of years. I remember the resistance against renewable energy veiling itself in a dress of economics, but in retrospect it seems incredible how little forward looking that resistance was, even in economic terms.
