On Monday, Sen. Michael Hastings (D-Tinley Park) introduced a 980-page amendment to HB 3666, which the senator, his colleagues and advocates said represented a new compromise among the various parties working on making Illinois’ energy industry more climate-friendly.

A new version of the omnibus energy bill that lawmakers declined to take up earlier this year appeared to generate renewed optimism among lawmakers, organized labor and some climate groups that the issue could finally be resolved in the coming days.
