If we don't expect nuclear to be an option (at least in the near future, for the US) then renewable energy may offer part of the solution. Recall that we only have significant electricity production from hydroelectric at this time but wind power is increasing its output at a rapid pace.
Cost of electricity is a key issue here. The renewable energies are more expensive! While wind has managed to reduce its cost dramatically, we are still waiting for solar cells and the other renewable technologies to become competitive, of course renewable energy enhances our national security, reduces air pollution (depending on what it is replacing as the energy generation source) and of importance in this lesson they produce no CO2!
