In the wake of the Fukushima nuclear disaster a year ago, Germany closed some of its nuclear power plants. Some have since reopened, but others never will.
Oil prices, which fell below $97 a barrel on Monday, are not poised to surge in the long run because long-term production is declining. Better technology and, if needed, higher oil prices mean the long predicted peak in oil production is a long way off.
At the heart of the fight is Gregory Jaczko, chairman of the Nuclear Regulatory Commission, who is under fire for his management style as the agency weighed safety improvements after the Fukushima disaster.
Experience in northern Japan illustrates that even incremental investment in nuclear power threatens human civilization. The Fukushima disaster should once and for all drive global society away from nuclear power, and toward renewable energy.
The 1986 Chernobyl accident was far worse than Fukushima has been. But the issues it raises are the same -- quality of industrial design, the potential for human error, the threat of natural disaster, and the disposal of long-term radioactive waste.
Based on new estimates of the radiation that has been released, Fukushima now has the worst score on the IAEA's accident rating scale. But much about the reactors, and their future, is still unknown.
This March 30, 1979, file photo shows an aerial view of the Three Mile Island nuclear power plant in Middletown, Pa. The small dome at center is where a partial meltdown occurred 32 years ago on March 28, 1979. A presidential commission later said the accident was 'the result of a series of human, institutional, and mechanical failures.'
