Two technologies have been going head-to-head to capture the public’s imagination. Both represent wholly new ways of doing things, and both hold tremendous potential. But what’s the reality behind the headlines? Which one really deserves the limelight?

Winter is a great time for solar—solar data, that is. Even if the panels themselves are covered in snow (which mine haven’t been, given our spring-like winter), this is the time of year when the industry’s progress over the previous year becomes clear. The annual stats for 2016 have just been released, and they offer still more proof that clean energy momentum is quite a thing to behold. Here are four graphs of solar progress to celebrate.

When I got into solar energy research in 1981, I wanted to change the world. I worried to my father that I’d never see widespread use of solar energy in my lifetime. That made him worry, too—about my future job prospects. As it turned out, there were plenty of jobs and I got to play my part in the history of human technology. I was one of a dedicated legion of scientists, engineers, technicians, laboratories and companies who eventually made photovoltaic cells into a commodity product: durable panels that achieve a miraculous-seeming conversion of sunlight to electricity, without needing any moving parts.

There seems to have been a significant uptick in the number of utility-scale solar projects announced in the Midwest recently—from Michigan to Minnesota , Indiana to Iowa, and even up in Wisconsin. Is this just a one-off bump in activity, or the start of something bigger? Are we actually starting to see the solar revolution spread to the Midwest where wind power has historically been king of renewables? And if large-scale solar is coming in a big way, are we ready?
