Fukushima Disaster Leads Japan To Backpedal On Emissions Pledge 274
mdsolar writes with this excerpt from the New York Times: "Japan took a major step back on Friday from earlier pledges to slash its greenhouse gas emissions, saying a shutdown of its nuclear power plants in the wake of the Fukushima disaster had made previous targets unattainable. The announcement cast a shadow over international talks underway in Warsaw aimed at fashioning a new global pact to address the threats of a changing climate. Under its new goal, Japan, one of the world's top polluters, would still seek to reduce its current emissions. But it would release 3 percent more greenhouse gases in 2020 than it did in 1990, rather than the 6 percent cut it originally promised or the 25 percent reduction it promised two years before the 2011 nuclear disaster."

This has never been shown to be an actual problem at Fukushima. I've complained about this attitude since shortly after the disaster happened. Where's the evidence that TEPCO acted incompetently? Instead, I see now as I did back when, that TEPCO recovered well from a huge disaster.
The Fukushima plant was exposed due to one of the largest earthquakes of modern history to conditions beyond its design specifications and it behaved as intended with a contained meltdown of several reactors.
TEPCO then acted to prevent the situation from getting worse. They've since expended considerable effort to clean up their mess and take responsibility for their actions (which includes compensating those who have been harmed by the Fukushima accident).
So where is this alleged evidence of incompetence?

That thread is instructive. My immedicate response to that claim was:
If someone does something incredibly stupid, like drive drunk and slam a car into a tree, what is there to learn? Don't be stupid?
What lessons were there to learn from Chernobyl? Japan didn't have reactors as unsafe as those used at Chernobyl. They didn't do stupid stuff nor were inclined to. They didn't fail to warn the public nor were inclined to.
There wasn't anything going on that was dangerous or stupid enough to where lessons from Chernobyl could have applied.

People need to realize a few things
The ideal amount of pollution is not "none". No pollution necessarily implies no resource usage.
To maintain a quality of life better than Ogg the caveman, we need to continue using resources to improve our comfort, safety, health, etc. Whether that is cutting down trees or burning coal, we need to continue doing both, because people want shelter, heat, and electricity.
To develop the quality of life we have now, we had to use resources and create pollution. People who advocate for sharp declines in pollution and resource use necessarily advocate stopping human progress.
Given how much suffering there is left in the world, suffering that requires our hard work, investment, and energy to address, people who ask us to stop resource consumption and power production are essentially anti-humanists. They, whether they know it or not, ask for more suffering, less comfort, and a reduced quality of life, for most people.
Perhaps there is a deeper underlying question to address.
What is the point of environmentalism? What is the goal of humanity?
Environmentalists often talk of "saving the earth". Sometimes, they say this in terms of "its the only one we have" and sometimes they are more honest and sinister when they explain that the Earth deserves to live long after humanity has died.
These latter type disgust me. We'll not discuss them further.
These former type are correct, but are missing the point.
While it is true that Earth is currently the only home we have, in my view it should be the goal of humanity to sustainably and indefinitely move beyond the earth to other worlds.
That is a significant undertaking; not everyone believes it is possible. I do.
We know that saving the earth is impossible. And our contributions to its demise are finally measurable, but are unlikely to be the fatal wound.
At some point, we will take a hit from a comet, meteor, alien race, etc, and it will end most or all human life on our home planet.
If we have not used our resources quickly and wisely enough BEFORE then to allow us to have permanently escaped the Earth, we have failed.
I think we should accelerate our usage of resources and production of energy, with a goal towards escaping this rock. Note that I said "a goal". Certainly making life better for people here who are here and alive today is ALSO a goal, and that also requires energy and resource consumption.
Obviously, building nuclear plants that are cleaner and longer lasting is a better way to do this than building more unscrubbed coal plants, but we need to accept that "more power production" is a necessary reality of the human condition, and get on with the show.
There are still people out there with no light and no heat. There are still people who die every year from flooding and basic sanitation issues.
Will you deny them new power plants when they develop enough to desire them?
It is horrendously myopic for people living the luxury of western lives to look around themselves, see that they are finally comfortable, and then demand that the world stop innovating and using resources to improve itself.
Finally, here's the bottom line about nuclear power safety: more people die _every year_ from petroleum drilling accidents than will ever get cancer from Fukushima emissions.

Japan has enough off-shore wind to power the entire country at all times, if enough turbines were build. Of course no-one is suggesting that as there would be other issues, but off-shore wind is a massive resource for Japan. In case you were wondering, the Kamisu offshore wind farm was not damaged by the tsunami despite being hit by it directly.
Offshore wind can provide base load. As long as it is distributed over a wide geographical area you can guarantee a certain amount of generation at any time.
Japan doubled its solar output this year alone. There is a vast amount of untapped energy there, and increasingly it is being paired with battery packs so that the energy can be used at night.
Energy efficiency is also a big deal. There are lots of new technologies, like LED lights that automatically set their brightness to maintain a constant ambient level in an office. Blinds that automatically rotate their blades to reflect as much light and heat into the building as possible are also becoming more common.
the plant designed for magnitude 7 took a hit from magnitude 9 which is a hundred times stronger and still survived it with no problems.
Actually no, it was damaged by the earthquake which was considerably weaker than magnitude 9 by the time it reached Fukushima. It wasn't known at the time due to the tsunami damage and radioactive leaks making inspection impossible, but some of the emergency cooling systems were damaged by the earthquake and wouldn't have worked even if the tsunami hadn't arrived. How well the plant could have survived that damage depends on what the operators did, so not good odds.
Fault lines have been discovered right under some reactors using new technology to locate them which was not available when the plants were first built. It is doubtful that any design could safely survive so much lateral force or ground liquification.

Even if it were true, the damage due to failing turbines is nothing compared to Fukushima alone. 50 trillion yen or more, hundreds of thousands of people affected, whole towns lost.
If "Japan's seismic instability and population density make it an inherently inappropriate location for nuclear power plants" as GP said, then the height of wind turbines makes them an inherently inappropriate location for machinery which needs to be maintained.
In fact no turbines fell over during the earthquake and tsunami. I'm not aware of any even being damaged. That includes the offshore ones that were hit directly by it.
You'd need to replace it with something on the order of ten thousand 2 MW wind turbines.
Current generation turbines are about 7MW, and you would need around 650 to replace Fukushima Daiichi. That would be possible with o

A few corrections:
Fukushima Daiichi took a magnitude 7+ Richter hit from the Great Tohoku earthquake, it was magnitude 9 at the epicentre out at sea. The plant's buildings got through that shock pretty well though (there may have been some damage to some internal equipment in the reactor buildings, it's too difficult to inspect them properly at the moment). The reactors at Onagawa further up the coast and closer to the epicentre rode out the earthquake and tsunami safely with no problems.
The tsunami killed about 20,000 people, not 30,000. Nearly all of them died because the towns and cities along the Tohoku coast weren't as well protected from the tsunami as the Fukushima Daiichi plant and other nuclear plants like Onagawa were.
Japan is currently burning mostly natural gas for its electricity generating needs. It has to import all of its fossil fuels and NG is as easy to transport and handle as coal and burns a lot cleaner. It's still releasing a lot of CO2 and causing an increase in smog and air pollution. Efforts are being made to bring about a dozen reactors back online this winter, whether that happens or not is in the lap of the gods.

Japan has been importing LNG for decades now and has the specialised ports to handle large quantities of it; the Chiba oil and gas terminal near Tokyo is one of them. It suffered major damage and fires during the earthquake but was speedily brought back into service.
Coal is about half the energy of LNG tonne for tonne. TEPCO generates about 40% of Japanese electricity and they are importing about 5 million tonnes of coal a year and about 24 million tonnes of LNG to burn in their fossil-fuel power stations.

The Japan of today isn't the economic powerhouse of the 80s IMHO. They crippled themselves by how they attempted to recover from their 1990 recession. So maybe they'll do as you say, or maybe they won't have the old advantages any more to compete in those areas.

Second, as we are seeing here, one accident can lead to a massive pullback from nuclear power, both in the affected country and around the world. Even France has announced a planned pullback. When the pullback is rapid, then relic fossil fuel plants rather than new clean energy replacements are pulled into service to make up the difference in generation. This makes nuclear power not just a slow response to climate change, but a retrograde response since these bad accidents are inevitable.
There are other ways it has a bad influence as well, such as pretending to be a silver bullet to the adolescent mind for example, so much time is wasted on fantasy scenarios. But these two big ones are bad enough.

Why exactly have US and China managed to stay on top of the list continuously for past few years, without managing to act the least bit "responsible"? Mod me troll or flamebait if you want to, but Japan even on per-capita basis is lower on list than most other countries. If US and Chinese politicians are willing to sit on their asses and screw the world, why this special onus of "responsibility" on Japan? USA could have done better, and should have so long ago. But US government was more busy trying to convince everyone that global-warming was a "myth" and attempting to argue that it was better to kill the planet than "harm the economy".

The simple answer - both China and the US depend far too much on coal for electricity, and there is currently almost no control over CO2 emissions from these plants.
45% of US electricity is coal and about 23% after that the 1/3 less polluting natural gas (which can be derived from coal, but isn't), after that is 20% nuclear and the rest mostly "green" energy. The EPA has proposed forcing new coal plants to adopt carbon capture technology, but Republicans (and yes, I call out Republicans, some of this info is from their coddling "news" site [foxnews.com]) oppose it for various reasons, usually citing it is experimental, expensive, and poses safety risks. What they don't say is it is about 1/3 less efficient in generating electricity and therefore impacts their constituent's profits, since their constituents can't regulate their own rate hikes (such is the life of a regulated monopoly). Thus the EPA has to focus on the other 55%, much of which has already taken place (automobile emissions standards, industrial emission standards, etc).
I don't know Chinese numbers, but the fact that they mine almost 4x what the US does suggests they are far more dependent on coal.
