Nuclear: Japan, US, China

Environment causes nuclear go down the drain as evidenced by Toshiba. Similar to coal. China has no choice not to use the bountiful of coal and many nuclear generators are being on-line.

It is quite a easy business decision by calculating the cost for a fixed amount of energy. Depending on the source in the internet, nuclear is about 4 times (2 times operational) more expensive than oil. If it is true, it does not take a nuclear Ph.D. to find it out and a ten-year old child to make the decision.

Japan's nuclear problem is not to take the old generators out of service and not to handle the used rods.
