Solar investment has increased by a factor of 11 since 2004. Solar installations have increased by a factor of 110. Today’s solar asset builders invest an order of magnitude more money than they did 15 years ago, and they build far more generation capacity.
And, like wind projects, today’s solar projects generate significantly more energy than those built 15 years ago.My colleagues expect trillions of dollars’ more investment in wind and solar technologies in the coming years, a volume of zero-carbon, zero-marginal-cost electricity that will significantly challenge the world’s traditional utilities. Investing even the same amount of money every year but getting far more out of it is hard to ignore
