Solar energy keeps massively outperforming expectations. Here’s a nice example. Every two years, the US Energy Information Administration (EIA), issues scenarios about how much solar, wind and conventional energy the future holds for the US. A new analysis has found that the EIA’s ten-year estimates between 2006 to 2016 systematically understated the share of wind, solar and gas. Solar capacity, in particular, was a whopping 4,813 percent more in 2016 than the EIA had predicted it would be.
