As President-elect Joe Biden prepares to take office, speculation is rising about who will fill key roles in his administration’s energy and environment teams. Names being floated for these positions include former Michigan Governor Jennifer Granholm, who is being considered for Secretary of Energy, and former EPA Administrator Gina McCarthy, who is a contender for a top environmental post. Other potential candidates include current California Air Resources Board Chair Mary Nichols and former Obama administration official Ernest Moniz. With the transition period underway, all eyes are on who will ultimately be chosen to lead the charge on energy and environmental policy in the Biden administration.
