For past years we had windmills, they were good for one person, maybe two if wind blows steadily
However it falls very fast in less windy environments and outright fails with more people in the settlement
From that point there were two ways: build more or upgrade to eventually quadmill so it can keep up with work piled up after breaks in power
But even then if both cases are true it won't be enough anyway - no point for those flax fields, trips for resin and saving fat if whole server has to grind in the workshop anyway
Now it's 1.22, water wheels came out and they're perfect! They actully help people lesser the amount of work they have to come through to equip the whole server!
The big windmill however... it's only job is to look nice on those absurdly high towers... well, maybe they're good in singleplayer - I don't play it much so I cannot say if that's true or not
