Clearly nuclear will be what keeps Japan powered well into the future. Their existing plants will give Japan what it needs to run and lessons learned will make sure that this sort of disaster does not happen again. Japan is not blessed with vast desserts to install solar or wind farms like China does, and with the high availability of nuclear, there is no need for all the complexities of intermittent solar and wind. France also has the right idea, and both Japan and France will be able to adapt to renewables after other countries have done the Lions share of the work to get renewables mainstream and more cost comparative. This is a much cheaper and less risky approach compared to other more fanatic countries. After all, they are not adding the dreaded CO2 to the atmosphere with this approach.
