Illinois grapples with implementing 100% clean energy law – Energy Wire

Transitioning to a carbon-free electric grid by 2045 is no small task. And no state should better understand that setting energy goals and achieving them aren’t the same. In 2007, Illinois adopted a law to get 25 percent of its electricity from renewables by 2025. As of last year, it was at 10 percent. Building a carbon-free grid comes with an array of dizzying technical and policy challenges and unanswered questions.
