Lee Cordner, former Pacific Gas & Electric engineer and long-time energy consultant, on the California blackouts.

In this episode, Robert talks to Lee Cordner, a former Pacific Gas & Electric engineer and long-time energy consultant, about the cause of the blackouts, the myriad problems facing the California electric grid, and why the state needs to keep its nuclear and natural gas-fired power plants operating if it wants to keep the lights on.
