Nuclear power can and should be the primary solution to the coming global energy crisis unless a major breakthrough in supercritical deep geothermal energy changes the game. The only option for adding more nuclear powered electricity generation right now is to build more conventional nuclear power plants using already licensed light water moderated reactor designs like the Westinghouse AP1000. It's true that rolling out nuclear will take more than a full decade but the real conclusion to be drawn there is simply that we should have started doing so at least a full decade ago. Without significant new investment in oil exploration and production petroleum prices will rise to economy crippling levels before enough new nuclear power plants can be built to fully solve the problem.
