Will Japan's New Government Restart the Nuclear Power Program? 177
An anonymous reader writes in with a story about speculation that Japan might restart its nuclear power program. "Japan's newly-elected Liberal Democratic Party (LDP), a strong supporter of atomic energy use in the past, should restart plants shut after the world's worst nuclear crisis in 25 years, said the CEO of Mitsubishi Heavy Industries Ltd .
The LDP, headed by Japan's next prime minister Shinzo Abe, won a landslide victory on Sunday, fueling speculation that the new coalition government would take a softer stance on nuclear power. Public opinion remains divided on the role of atomic energy after natural disasters last year triggered a radiation crisis at the Fukushima Daiichi plant."

Most solar panels end up in small installations, where they compete at the small consumer price levels.
Which will work for a while.
But ultimately in a situation dominated by local generation power company charging models will have to change. The service of moving power around will still be needed and will still have to be paid for even if most customers generate as much as they use on average.

But instead of re-certifying decades old plants with iffy designs how about building new ones with better safety features? Job creation too.

As to all the techophiles here: What kind of fuel do you think we are going to use to explore this solar system? Fusion is looking worse every year. And fission? Forget it, there is not that much Uranium available in the first place. And it is being wasted for generating electricity where perfectly good alternatives are available. Stupid, stu

It's worth noting that by "landslide" you mean they got 28% of the votes, with support of 17% of eligible voters, and actually received somewhat fewer votes than in their disaster election three years ago. A mandate it is not.

You know, for all the flack that the “first past the post” voting system takes in Slashdot you have hit on one of the strengths of FPP – landslides gives the winning party the power to rule and to execute their party platform.
In this case LDP won 294 seats of 480, giving it a majority. With New Kometio 31 seats it has a super majority. I don’t know all the nuances in Japanese politics, but sometimes it’s necessary to have a super majority to prevent the minority party for block

I agree with what you say, that developing solar and wind and hydro power can't keep up with the rate of growing demand. However, this article [ieee.org] from last year's IEEE magazine points out there is enough renewable energy to meet the world's needs.

So, with enough discipline and forethought, one could use nuclear power as a transitional step away from fossil fuels, and later replace nuclear plants with wind and solar as they age and need to be decommissioned.
I'm not so sure we are going to ever totally replace them in this progression. Renewable sources are not usually very reliable. If the wind doesn't blow, windmills are useless. Or if it's midnight, there is nothing a solar plant can do for your power consumption needs.
What we need is a market based 'all of the above" solution.

So why does Germany still produce about 11 tonnes of carbon dioxide per capita per annum while France's carbon load is about 5 tonnes (and has been for the past 30 years or so after their dash for nuclear generation in the 1980s)? The answer is in the amount of coal and lignite Germany continues to burn to generate electricity along with its greenwashing wind and solar plants.
Germany's consumer electricity prices are double that and more of France since nuclear power is cheap, cheaper even than coal in te
