Puerto Rico could see ‘significant epidemics,’ health experts warn.

A new report from the International Energy Agency surveys the growth of hydropower, wind, and other forms of renewable energy and finds they’re catching up to coal (still the world’s largest source of electricity). At this rate, renewables are expected to provide 30 percent of power generation by 2022.

Hydropower provides the most renewable energy, but the growth is in solar. One wrinkle, though: It can be misleading to focus on the number of panels installed, because solar only works when, ya know, the sun shines. So keep in mind that, while the graph below shows how much new “capacity” we are adding to the system, only a portion of that gets turned into electricity.

Denmark is leading the way on clean energy installations (shocking, I know). The Scandinavian country currently generates 44 percent of its electricity from wind and solar, and by 2022 it’s on track to get 77 percent from the same sources. (VRE, used in the graf below, stands for “variable renewable energy” — the term of art for wind and solar plants that we can’t switch on as needed.)

If renewables keep growing as forecast, we’re going to need bigger electrical grids (to move electricity from places where it’s generated in excess to places where it’s needed) and better ways to store energy.
