In what has to be one of the dumbest knee jerk reactions I've seen since 9-11 and the passing of the unpatriot act Japan has decided to take all their nuclear power plants off line.
Nuclear power supplied around 30% of Japans power and was one of the few domestic energy sources.
Right now it's for maintenance and safety inspections of course smarter would be to do this sequentially starting with oldest and most at risk plants.
Now the dumb part imported natural gas and oil is being used to make up the power short comings but this is both extremely expensive as these energy sources are 2 to 3 times as expensive as coal and nuclear power but also unable to keep up with demand.
They expect a 20% power shortage this summer causing rolling black outs and power rationing.
Some groups want to leave them off line permanently though what would they replace them with?
I can understand maybe phasing them out over ten or 15 years which would give enough time for alternatives like wind and geothermal to replace them.
But shutting them down all at once without a viable and affordable replacement is economically suicidal.
