    I cannot upvote enough, I just heard distance is a problem and I needed a kind stranger (like you) to explain why that’s not a problem.

    Got any references for me to read? I would like to learn more

    PS fuck capitalism

      It’s not a problem insofar as it costs more than what we are doing now.

      It may not happen because renewables and batteries are on such aggressive cost curves that it may be better to just store energy locally or produce more (and thus generate flexible high energy cost economic activity on top of the current energy demand that can happen whenever).

      Transmission and distribution currently costs in the ballpark of 3-7c/kWh. Longer distances will drive this up. Overnight-scale storage will drive it down (allowing it to run 24 hours a day at x watts rather than 4 hours at 6x watts).

      Solar energy is 1-6c/kWh. Overnight-scale battery is 2-7c/kWh. If you can rearrange your manufacturing so you do the energy intensive bit on a cheap machine on a sunny day and do the labour intensive bit on expensive machines in winter, you won’t consider transmission. If you can’t, you’ll weigh transmission against moving your factory to western australia or morocco or texas. Many processes have a drying or a reduction (removing oxygen with electricity or chemicals made from fossil fuels/electricity) or heating step that fills the first profile.

      End result is there will be a mix with countries that have less seasonal variation having an advantage in industries that are less flexible (because hitting the worst-case load will require less infrastructure), and countries with more seasonal variation having a huge advantage in flexible industries (as their winter heating bills will subsidize the free summer solar). Transmission will play a role too (but how kuch is uncertain).
