    @Ardubal @Sodis

    We have to be careful. Different counties have very differnt energy make ups. I live in the UK where nuclear is

    I don’t understand where you got 40% from. This seems arbutrary.

    In the UK Nuclear is 15% and renewables about 40% (over the last year) we mainly burn gas for the rest.

      @MattMastodon @Sodis Careful about labels. »Renewables« often includes biomass (which is just fast-track fossil tbh) and hydro (which is not so volatile). I’m talking about wind and solar specifically (volatiles).

      40% is roughly the mean capacity factor of a good mix of volatiles. This is what you can directly feed to the user from the windmill/panel, without storage. You can expand a bit by massive overbuilding, but you can’t overbuild your way out of no wind at night.

        Mostly we don’t use energy at night. In the UK there is a peak in the morning. In the UK we mainly use gas to fill this. We will have to find a storage solution as nuclear can’t be upscale that quickly. Gas was meant to be used just to fill the gaps but it’s quickly become a staple.

        We need to find a way of smoothing the graph. Energy storage is the best option in the short term.

        Or we can vary use.

          @MattMastodon @Sodis Again: that demand is lower at night is already factored in. Roughly 40% of demand can be directly met by volatile sources. You may think nuclear is slow to deploy, but it’s still much faster than anything that doesn’t exist.

          The gap is 60%. Gas is a fossil fuel. Varying use is mostly a euphemism. If you hurt industry, you won’t have the industry to build clean energy sources.
