Japan looking at 15% nuclear energy mix

Japan may look to generating 15 percent of its electricity needs from nuclear power, a minister said Friday, as the country seeks to rebalance its energy supply after the Fukushima disaster.

A government panel studying future energy policy has presented several options, from one that sees a nuclear-free future by 2030 to one that seeks to increase dependence on the technology to 35 percent by that date.

"Fifteen percent can be one base," environment minister Goshi Hosono told reporters, noting that government limits on the operation of nuclear power stations to a maximum 40 years would be in line with this figure.

Prior to tsunami-sparked meltdowns at Fukushima, resource-poor but energy-hungry Japan relied on nuclear for about a third of its electricity needs, a figure policymakers intended to boost to 50 percent.
