In an hour-long ceremony held yesterday at Chicago’s Shedd Aquarium amid some fanfare (it included an appearance by lizards, a snake, and a penguin), Illinois Gov. J.B. Pritzker signed into law the Climate and Equitable Jobs Act (S.B. 2408). The bill is a sweeping overhaul of the state’s energy policies aimed at phasing out fossil-fuel power generation and placing Illinois on a path to become a 100 percent carbon-free energy producer by 2050.
