I'm not decided on the issue, but my answer would be:
You think in short terms.
Quite on the contrary. We can't hope that nuclear fusion becomes commercially viably anytime soon (form what I've read on the issue, the optimists say it could become viable by 2050s), and until then we need to cover our rising energy demands.
We can conserve energy, and I support that. We can try to increase the share of renewables and I support it too, if it doesn't contradict common sense (sometimes the renewables are simply too expensive and eco-unfriendly). But even with these measures, we will still need a lot more energy in the next half a century.
There is enough coal to produce this energy in conventional coal power plants, but since that produces a lot of CO2, we don't want that. We can't build more hydroelectric plants in Europe as all the available places already have them, or they are protected natural reserves. We can't rely on renewable sources, because these sources generally need backup due to their inherent unreliability and unstable output. Geothermal energy isn't viable in most of Europe.
This leaves us with ONE SINGE OPTION - the nuclear energy. Especially if we have any intention on introducing electromobiles or hydrogen-powered cars - you need to get the electricity somewhere.
Having a nuclear plant run another 10 years would give us another 10'000 years of time til the nuclear waste has vanished. (or something like that). So if you believe in long term, there is no reason to keep it going any more, the scale of the damage is exponential.
What damage? There are few facts you're missing in your equation:
1) Most of the so-called nuclear "waste" can be reprocessed and used again in different types of reactors, which are already approaching economic viability.
2) The actual amount of unreprocessable nuclear waste is just a fraction of the overall amount of nuclear waste - about 5-10%, I think.
3) This amount of nuclear waste can be safely stored underground without any risk whatsoever for anybody. This is not black magic we are talking about, this is science and technology. Science say that if you bury radioactive materials under a thick enough layer of rock, nothing can go through. Technology allows us to build such underground vaults and ensure that the waste is stored safely.
So again, where is the damage? I see none.
Again, it's more ideology than factual thinking. What is the goal? to live peaceful and not destroy our planet, go green. to be energy-independent from other countries and have enough for your own, go the other way.
The point is that nuclear energy is
a) the safest available source
b) the most economically viable one
c) the one that ensures greater energy independence of Europe
d) the one which doesn't pollute the atmosphere with greenhouse emissions
e) the greenest one - you need only few big nuclear power plants to power a whole country, not thousands of smaller ones. The whole energy demand in the Czech Rep. could be covered with just four medium sized nuclear power plants. We currently have 2 which provide over 40% of our consumption. There is a discussion going on about another one, which could put this number at some 60 or 70%.
Who am I to tell you which is more correct?
Again, this is not a matter of ideology, but science and technology. The matter should be discussed on this level. Unfortunately, people are bringing their irrational fears into this, which is not acceptable, especially if their fear can threaten the future of the entire continent.
And in correction to my previous post. Of course one can talk about politics and issues like the economy, but let's not pretend that we have the slightest clue about the whole thing. It's just too complex for us single humans. So the discussion really boils down to the question of "more or less state" for me. Which if spelled out, pretty much gives you the 5+ parties the election is about. Subjective choice.
Don't be so relativistic. With such an attitude, you could never seriously discuss any matter.
I am saying that the decision to decommission all nuclear power plants in Germany was totally insane and based on nothing but populism and pandering to people's hysteria about nuclear energy. Just as other countries in Europe have reversed their decisions to abandon nuclear energy, I am really hoping that the next German government is formed by sane people who have the future of their country in mind, not just the votes and victory in the next elections.
