Nuclear energy is not a free but it kills a lot less the coal, so closing nuclear plants and using coal plants like Germany did is stupid(the decision was pure political and forced by the Green party, ironic)

Acutally, On 26 January 2019, a group of federal and state leaders as well as industry representatives, environmentalists, and scientists made an agreement to close all 84 coal plants in the country by 2038. It is especially Solar and Wind that are on the rise in Germany https://en.wikipedia.org/wiki/Energy_in_Germany https://en.wikipedia.org/wiki/Energy_in_Germany

  It seems like they got the order wrong though.

  The damage will be done by 2038. We need to stop pretending we have time to slowly wean off of fossil fuels. We're already facing feedback loops that are going to drastically change the climate. Just look at the graph on that page. Renewables have largely replaced nuclear... Which is largely a clean energy source while coal has barely changed and the use of gas has slightly increased. Except now we have nothing to cover baseload except for coal and we're still building new coal power plants.

  Germany has always had a good environmental track record, which is why their bad decisions are interesting. It tells us about communication problems between researchers who study the impacts of energy generation and voters who are concerned about protecting the environment.

    And politicians who were happy to simply outsource CO₂ emissions by closing their nuclear plants and buying electricity from other countries, which generate it from coal.

      Yep - it's not in their electoral backyard. Another angle is that it seems Germany is becoming a giant in renewable tech. I mean, it looks like their big bet on that is paying off in pure economical terms. So the voters are unlikely to punish politicians for a move that seems to spell a lot of export money for Germany.

  They could have replaced coal with all the new renewable energy sources and thus reduce the CO2 output. But instead they somehow decided it was a good idea to shut down nuclear power plants before they shut down the last coal plant. Per TWh produced, coal kills more than the power produced by Chernobyl. Generation 4 reactors will very likely begin operation in the next 6-10 years. Just look at the integral molten salt reactor as an example.

  It is great, but 18 years is a long time. Nuclear is the one realistic approach to bridge the gap, and I am not sure we have others.

Nuclear energy is used a lot less than coal and kills a lot less than coal. Let's see how it goes when reactors replace power generation in third world with poor safety record and in upcoming warzones. We nerds love technology and this is really the main reason for strong pro-nuclear sentiment in places like HN. Health effects or emissions footprint have little to do with it.

  I think you imagine that a nuclear power plant would explode like a nuclear bomb, that is not the case. The fuel used is not the same as in the one in bombs either so you can't put some masks on and rob the nuclear plant.

    I lived some 200km downwind from Chernobyl when it happened so have pretty solid concept of reactor failure modes.

      I agree that there are risks and waste from nuclear, my main issue is that for some reasons coal plants have larger damage to the environment and population. My opinion is that we should not rush on building new nuclear plants but finish the ones that are already built, use them to full capacity , invest into research for the safer nuclear versions. I would not like to have a nuclear plant near my house, but if you have to chose between a coal plant that is polluting and radiating all the time is running and a new nuclear plant design that it would fail only in super rare events (there are designs that would be safe even if the cooling system fails) then I definitely don't want the coal plant. Btw nuclear is used in medicine, there are labs that use radioactive materials, I think the number of this would grow and it may end up in countries you don't trust but you can't stop progress,

        Natural gas burns quite cleanly. There's a number of European nations that don't have a single active coal power plant and they get by somehow. The reason nuclear crowd loves to focus on coal is it's the worst case conventional technology and hence the easiest to argue against. The arguments against hydro, wind or NG are a lot less convincing.

Most people aren't afraid of responsibly run power plants. They are afraid of what those power plants can be used for (building nuclear weapons).

  This is the problem, you can't build a nuclear weapon with the fuel in a power plant, misconceptions like this cause a lot of damage to the entire planet.
