Lamar's energy plan

Via Instapundit, here's Lamar Alexander's 7-point plan for energy independence. It's not clear exactly what the senator's suggesting by such points as "Make carbon capture and storage a reality for coal-burning power plants." Does the government subsidize it, mandate it, what? I suggest a vastly simpler 1-point plan: Institute a carbon tax, and let the market decide which of Lamar's seven goals are doable and when.
