President Barack Obama’s flagship effort to clean up the nation’s energy supply is now on hold, and its uncertain fate rests in the hands of whoever moves into the Oval Office next year.
That became clear this week when the the Supreme Court blocked the Environmental Protection Agency from enforcing its Clean Power Plan—an unprecedented move, considering the case is still being argued at a lower court. With arguments scheduled for June at the D.C. Circuit Court, the case likely won’t reach the Supreme Court until 2017 at the earliest.
