> the decision on what energy sources to use is not a Yes or No decision
This is not exactly what I meant. With "can be rendered as a Yes or No decision" I meant that any more-or-less question "can be refomulated, so that someone can vote either in favour or against", which is what happens when a debate needs to be brought to a practical conclusion. (Well, there is of course also the option to abstain from voting, but the question is nevertheless finally a Yes/No decision.)
> a country is not likely to significantly lower their energy consumption.
There are already a lot of laws and regulation targeting energy and resource consumption in the EU. And a lot of new ones are on the agenda. However, there might exist conflicting goals: for example, shifting towards electrical cars to lower CO2 output results in larger energy consumption, because an electrical car is much heavier than a comparable conventional one. It may not always be the best solutions that end up being implemented, but the general direction is to look not only at renewable energy, but also at energy and resource conservation.
> Similarly, with waste, if they see a picture of low level radioactive waste form 20 years back, they think it is the same as fuel that was taken out if the reactor the day before.
I think that a lot of people in Germany understand the general concept between low-level, medium-level and high-level radioactive waste quite well. My generation and people older than me were victims of Tschernobyl. We were all told that radioactive iodine was an immediate threat, but will become irrelevant very quickly. We hear that radioactive ceasum is still a problem with mushrooms and wild boars from the Bavarian Forest. The concept of its accumulation in the food chain is common knowledge.
> Similary, they tend to think that if the waste is dangerous for 100 000 years, it is almost as dangerous after 50000 years as it is after 50 years. While in reality, around 300 years is what it takes for it to become "relatively safe", even if it is still not completely harmless.
The problem for long term storage of high-level radioactive waste is that after a few hundred years, when all short and medium active material has more or less decayed, the decrease rate itself almost stoped to decrease further. The waste is then about 100 times less active than initially, but it will take between 100,000 and 1,000,000 years for the waste to reach the activity level of natural uranium ore, which itself is not yet harmless.
> In other words, the general public is relatively easy to mislead with propaganda.
We are talking here about a decade long debate in an open society, where not only ordinary people, but thousands and thousands of expert of different related fields and various opinions participated. The tale of a general public that had been mislead with propaganda is a pattern of argument that is typically used by anti-democratic movements. The general public does not consist of stupid individuals. The general public of an open society is a collective rationality where people with all their different backgrounds and level of expertise can freely debate the issues that concern everyone. Its conclusions might not be perfect and not always be right, but it is the best we can hope for. If the arguments you favour do not get through, it is not because of propaganda, but because they have not (yet) been convincing. Try again. There is always another election.
> An the topic of Nuclear energy vs Coal/Gas (after actually doing some investigation), the data I have been able to find, indicate that the case is almost as clear as Evolution vs Intelligent Design. The difference is simply so large (around 2 orders of magnitude or more), that even if there is significant bias/skew in the data I have available, it is not likely to be enough to alter the conclusion.
I would say that "Nuclear energy vs Coal/Gas" is a debate of the past. Germany wants to switch completely to renewable electrical energies by 2035 (all energies by 2045). This renders plans for new nuclear power plants obsolete. Realistically it might take one or two decades to go from planning to operation. So when the plant starts it will already be obsolet.
You might argue that in the light of the current situation, Germany's last three nulcear plants to be shut down this years should run a little longer. This option was briefly considered even by the Minister of Economic Affairs, Robert Habeck from the Green party, but quickly dropped again. There were a few voices in favour of such a proposal from the industry and the Conservative opposition, but others, even from this circles, said that it was too late to realistically postpone the shutdowns already scheduled and underway. So after a few days, no one followed up on this idea.
