Growth in german wind capacity is slowing. Soo… then the plan is to keep on with lignite and gas? Am I missing something?

    Don’t import Reddit’s extremely ignorant takes on nuclear power here, please. Nuclear power is a huge waste of money.

    If you’re about to angrily downvote me (or you already did), or write an angry reply, please read the rest of my comment before you do. This is not my individual opinion, this is the scientific consensus on the issue.

    When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

    If you’re about to lecture about “it’s not possible to have all power from renewable sources”, save your keystrokes - the majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Again, this isn’t my opinion, you can look it up and find a dozen sources to back up what I am writing here.

    This is all with current, modern day technology, not with some far-off dream of thorium fusion breeding or whatever other potential future tech someone will probably comment about without reading this paragraph.

    Again, compared to nuclear, renewables are:

    • Cheaper
    • Lower emissions
    • Faster to provision
    • Less environmentally damaging
    • Not reliant on continuous consumption of fuel
    • Decentralised
    • Much, much safer
    • Much easier to maintain
    • More reliable
    • Much more responsive to changes in energy demands

    Nuclear power has promise as a future technology. It is 100% worth researching for future breakthroughs. But at present it is a massive waste of money, resources, effort and political capital.

    Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on nuclear power should be spent on renewables instead.

      How do we deal with balancing the uneven load renewables produce in places where pumped hydro isn’t an option for power storage? I.e. lowland areas. Here in the southeastern US, night almost always means no wind as well as the obvious no sun. Chemical batteries, afaik, aren’t a sustainable solution ATM.

        Thanks for the question. Firstly, most places have a power grid which is far larger than their locality. For example, the southeastern United States is connected to a single big grid which connects every smaller sub-grid east of the Rocky Mountains. This means that a home in Florida can be powered all the way from the Bath County pumped-storage facility in Virginia, the second largest such facility in the US.

        Hydroelectricity can also be generated by rivers, which are commonly used in lowland areas, and geothermal is also viable at any time of the day. Biomass is also an option, though it’s the last resort really, although as long as it’s responsibly managed, it can be nearly carbon neutral.

        There are also alternatives to pumped storage, lots of them. Compressed air, thermal storage, and hydrogen are a few examples just off the top of my head, though I’m sure there are many more. Pumped storage is just very efficient and cheap, so if we can plausibly do it, it should be the first choice. And if it can’t be done somewhere, then we should connect that place to somewhere which can!

          Hydroelectricity

          Destroys aquaculture. TVA has absolutely killed those rivers, and there is no way to sugar coat that.

          Geothermal can’t be used in most places (but should absolutely be used where it can be)

          Biomass is just burning shit all over again (thought that was the point of not burning coal).

          I’m also skeptical of the pivot from using renewables as a decentralized solution and then touting a massive grid which requires lots of infrastructure. Unless your problem with centralization is targetability by bombing.

          I’ve not heard much about compressed air as an energy storage medium, or thermal storage besides from using solar arrays to reflect light and melt a metal core (like Gemasolar which is another centralized solution), but I’ve heard nothing good about hydrogen except from breathless techbro types.

          Meanwhile Nuclear is a mature technology now, absolutely a less dangerous solution than coal (even without looking a climate change knock-on effects, just looking at the effects coal dust has on populations near coal-fired plants), and can be used to meet the base-load of a local grid with various renewable solutions used to meet peak load demands.

      Wow I’m surprised to see people are actually downvoting you and arguing about this. It’s common knowledge that the cost, impact, and build-time of new nuclear plants makes them a poor choice for energy. Not only is wind/ solar cheaper, it’s faster to build.

        It’s also common knowledge that the more often you build something, the lower its price tends to go as that knowledge spreads. It’s part of the reason it’s so expensive to build trains in the US and so cheap in South Korea and Spain.

          This famously isn’t true for nuclear power. It just keeps getting more expensive.

          The French nuclear case illustrates the perils of the assumption of robust learning effects resulting in lowered costs over time in the scale-up of large-scale, complex new energy supply technologies. The uncertainties in anticipated learning effects of new technologies might be much larger that often assumed, including also cases of “negative learning” in which specific costs increase rather than decrease with accumulated experience.

          https://www.sciencedirect.com/science/article/abs/pii/S0301421510003526

          And this research was done before Fukushima, which increased costs even further.

      If you are worried about the cost of nuclear energy, you don’t give a shit about the environment.
