    Being pro-nuclear was a very valid position up until a few years ago. Now solar has gotten so cheap that there is practically no reason to do it except to protect yourself against US imperialism.

      The trends on wind and solar have been clear for at least a decade if not more. The time for nuclear was last century when it had no serious competition.

      Nuclear reactors could still be useful in things like the mass production of hydrogen through steam electrolysis or even using fancy stuff like thermochemical reactions.

      I know China is planning on building the world’s first nuclear reactor integrated into an industrial area for the production of very hot steam.

      Solar still has some huge problems when it comes to seasonality and day/night cycle. You either need massive battery build out or some other form of energy to handle base loads and/or offset when solar isn’t producing enough.

      Not saying solar isn’t part of the future, but we literally can’t just rely on solar.

        Solar panels have become more than ten times cheaper than they were a decade ago. They are easily able to gather half the energy of what they did a decade ago in the summer now in the winter.

        So even in the winter solar is twice as price efficient.

        Yes there is downtime but solar is a fast and cheap way to replace most electricity cost. Then the rest can be fixed with nuclear in 20 years. We need clean cheap energy now and we can mostly get it.

          I’m not talking about price, I’m talking about generation.

          I have solar panels, they are great. However, I get too much energy in the summer, not nearly enough in the winter, and no power at night. Since I’m on a grid that doesn’t matter too much for me, but highlights some of the issues.

          Even if I installed a battery, I’d end up with extra power in the summer and not enough in the winter. Which just highlights the discrepancy in production. Batteries obviously help solve this, but some mixture of wind/nuclear/other is needed.

        Battery tech is getting super good though, and the materials are recyclable. If solar becomes cheap enough we could even store it in creative (but less efficient) batteries like lake batteries or weight batteries and the like.

          I had heard of lake batteries over the years, but never a weight battery. Thank you for teaching me something new today!

          You know what else I haven’t heard of in a while? Thermal solar, where they use a parabolic mirror array to concentrate the sun onto a small tube full of water pushing a steam turbine. Even the plain steam could be used for heating and more. Steam can absolutely be concentrated under pressure (more of a capacitor than a battery since the temp won’t hold, but it does provide stability). The steampunk future from comic books is at our finger tips only we will generate the steam using the sun rather than big factories of iron and steel.

        This isn’t a problem at City scales and beyond. You just can’t buy a bunch of nazi batteries so there isn’t a corp greasing politicians to build it.

        This is true. I am mostly pro-solar and mostly anti-nuclear, but if we decided to build a huge multi-national plant to combat/reverse global warming and it needed obscene amounts of energy to operate, I think that might be a perfect task for nuclear. The same doesn’t hold true for AI data centers though. I hope those guys have to generate their power by daisy chaining potato batteries.

      Nuclear, both fission and fusion (which will never happen anyway) are relics of an era of cheap fossil fuels and relative world order.

      Solar electricity is viable at scale but also indicates a change in our species’ living arrangements on this planet.

        That’s an interesting way to look at it. If it’s not just about the power and the cost, there are actually a lot of other factors that we have glossed over.

        Solar is cooperative and local while nuclear necessitates centralization. In a nuclear future, large nuclear generating corporations are the sellers and we are the buyers. In a solar future, we pool and exchange our power depending on current production ability and current electric need… comrade.

          Yes, but the bonanza of fossil fuels that rocket-propelled humanity from 1859 onwards with chemicals and pesticides and fertilizer is not sustainable with only renewable energy and resources.

          For example:

          https://en.wikipedia.org/wiki/Green_Revolution

          You think things are kind of uncomfortable now wrt inflation and fuel prices? Oh hold on, it’s not going to get better!

            You should read up on the topic, I know I was surprised, the breakthroughs have recently happened. Now it is just permitting and building. Obviously there will still be issues, but there is little question to the reality now.

              I’ve read of smaller reactors that should speed up prototyping, but nothing about actual net positive energy production. That’s still far away.

                This happened a long time ago. Prototyping is over. I was very skeptical as well up until they figured out a practical reactor design and are in the process of building and permitting several commercial plants around the world.

                  Thankfully there’s no Big Fusion propaganda. Might want to check your face for a gigantic hook.

                  There is no system capable or conceivable to generate net electrical energy at commercial scale.

                  None.
