  • Tell me why I should wait decades for a single power plants worth of capacity

    It’s more like “A decade”, and i’ll explain, because it’s actually much less nice than these infographics show.

    So, doing the maths for you: 1 Wp ~ 0.85 kWh over a year. So 10 gWp ~ 8.5 gWh per year. But they only produce about 3% of that in winter, so about 255mWh in januari or december. That boils down to about 1/8th of a nuclear reactor. So, in reality it takes it takes at least 8 years to match one nuclear reactors, assuming you like keeping the lights on during winter.

    But it gets worse, because they produce that power over about 8 hours (being generous) and don’t do anything during the other 16. So on top of literally an entire nation’s worth of solar panel growth you need to also STORE that power for at least 16 hours. Thankfully, Germany also added about 7.3 gWh in 2025, which is enough to cover that with (some) room to spare.

    You could, of course, build two reactors at the same though. You can’t really double a country’s solar growth. And nuclear plants have MUCH longer lifespans than solar panels and especially batteries.

    And most oft all, I don’t have to care about hazardous waste disposal for centuries to come.

    Tell me, how much nuclear waste is there actually? Like, take a guess how much waste that takes centuries is actually produced per, I dunno, human-lifetime-of-power.


  • I wasn’t refering to you personally.

    I was refering mostly to the anti-nuclear crusaders from the 70’s and 80’s who were so anti-war, they figured “Nuclear bomb bad, so nuclear bad”, and decided that civilian powerplants were building bombs without any evidence (or even basic understanding) and thus everything related to nuclear power was the devil and needed to stop.

    Of course, if you do believe that or their propaganda, I actually was talking to you. The maths aren’t hard though, you can do them yourself. The nuclear industry is incredibly transparent and you can google almost anything. That, of course, makes it very prone to lies and deliberate misinterpretation, for example when people say there are huge amount of nuclear waste! (which is sort-of-true, but the overwhelmingly vast majority of it is low-level).


  • Tell me you don’t understand waste handling without saying you don’t understand waste handling. There are “temporary” solutions for ALL waste ever.

    Nuclear waste is such a tiny little problem, that stacking every spent fuel rod ever, inside it’s storage cask, in one pile wouldn’t even fill a decent soccer stadium. If you just looked at the fuel itself, the same waste wouldn’t even reach your knees. If you powered your entire life with nuclear power (and I mean transportation, manufacturing, heating, lighting, etc) with nuclear power, the resulting spent nuclear fuel for your entire family would be slightly less than a 1-inch cube.

    I can’t stress enough how nuclear waste is a total non-issue that was invented by the fossil fuel industry and misguided idiots who understand neither basic physics or (much less basic) general waste handling.




  • This is a myth

    That’s a great supported argument. The only argument I made that requires a source is the one about the house. I based that 20k and 500k on my own (dutch) house, which runs net-zero spread over the entire year, but produces less than 1kWh per day in january. I would need aproximately 7 more rooftops to cover my power needs during winter, or about ~400k in lithium cells (plus charge controllers, converters, etc) to store power for half a year. Exluding the emotional cost of my fire insurance laughing in my face when I propose this.

    Would you like to explain why this is a myth, or where exactly I’m wrong?

    Also, France is currently one of the largest electricity exporters specifically because of super cheap nuclear power. They indeed don’t exist in isolation.
