Skeptical about renewable energy predictions? You should be.
"we weren’t the only ones that were timid in our predictions of renewable electricity’s potential. Based on data collected by the Renewable Energy Policy Network for the 21st Century, many experts were way off on how wind and solar electricity would grow over the last decade."
