This Sunday, Americans will watch two teams go head-to-head in the first NFL stadium powered by 100% renewable energy. I joined @CBSNews for a tour ahead of the big game to get a glimpse into how the world of sports is making strides in clean energy.
#SBLVIII could make history, as hosts at @AllegiantStadm say Sunday’s game will be the first Super Bowl powered entirely by renewable energy. @benstracy got a look at the 621,000 solar panels in the Nevada desert that will power the big game — and Usher’s halftime performance.

Exclusive: A geothermal startup showed its wells can be used like a giant underground battery. If these field results work at commercial scale, it could become cheaper and easier to eliminate greenhouse-gas emissions from the grid. trib.al/1j6pk3V

First on the list? Fusion. 😎 @Livermore_Lab announced "they had produced the first fusion reaction that created more energy than was used to start it. The long-elusive achievement marked a major breakthrough in harnessing the process that fuels the sun." theweek.com/in-depth/1019386…
