I think actually nuclear is the only scheme that we have for our energy needs.
For instance, in France, since we have the nuclear reactor, electricity costs 40% less than in other European countries.
This thing could succeed merely in France nowadays, though we have a new technology called EPR, that can bear the blaze of a Boeing on his roof amongst other stuffs. Even if there is a meltdown of the reactor like in Japan, the French technology is capable to avoid the leaks of nuclear breath for the population.
So, it's very sad and a bad news for Japan. We must do careful in the future where this technology is sold and settled (even if France does actually that, we have to watch), due to the fact that it may be responsible of uninhabitable cities for years where there are irradiated zone.... In the same time, we are consuming to many in comparison of the others ways we could use for make electricity, and even Germany who have invested a lot in others sorts of production, is coming back toward nuclear. Italia too, as though they've stopped during more 15 years all nuclear electricity.
In fact, governments actually say they will cease all projects or rethink about, but they know the facts and the issues. There will have no debate, because if we will do a referendum, too many would choose to stop it unlikely to the prove of our needs by our way of life....
The only thing I find very necessary and it's an utopia on my own...is that we should seize this like an opportunity to imagine an other world, with nuclear central all over the world furnishing all countries and making that it can not manage an other time for example in Japan. The resources should be organized like in a pool for all countries and settled at the better places possible in the world for that...But what it imply, any government is ready....^^
