    @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.
