“When you look at the absolute numbers...it is completely sort of mind-blowing.”

The details of solar’s expansion are even more surprising

Not every country is riding the solar power rocket to the sun just yet. Individual countries have seen peaks and dips in solar installations based on how well their economies are doing and how strong their policy incentives are, like feed-in tariffs, net metering, and tax credits.

In the past couple of years, the global story has really been about China. Add up every solar panel installed in the US in history and you get how much China installed last year alone, almost 60 percent of all new solar installed in the world. The sheer scale of this deployment broke a lot of forecasters’ models.
