And did the general conclusion change that wind wouldn't be able to provide more than even half the energy we need for transport?

  Yes. The conclusion has changed! Electric cars are ridiculously efficient. A 100kwh tesla drives approx 500km. So 50km/day/car needs just 10kwh. The UK also has 2 persons per car (plus additional cats and dogs..) So just the on-shore book projection is already enough AND only requires a tenth of the turbines. Lets keep nuclear as well. Invest in efficiency. Lots of hard work ahead. But we are probably closer to "problem solved" than to "civilization collapse". Cheers.

    Just to flag that MacKay already estimated (in 2008) a Tesla at 15kwh per 100km (actually better than you have here). See Fig 20.22 on https://climate.lifeitself.us/without-hot-air/chap20/ https://climate.lifeitself.us/without-hot-air/chap20/

      I am less concerned about the consumption, but the issue how much available wind energy we can harness in a best case scenario. Only half of transportation seems so low.

    > 50km/day/car For what it's worth "In 2019, the average car in the UK drove 7,400 miles"[0] which works out to 33 km/day/car. It's probably much less now due to working from home (and fuel shortages, and the collapse of the supply chain...)
