Comment on Vienna would need about 150 km² of solar panels to produce enough electricity

I think your calculations are off.
Also where did you get this 30 megawatt per person number from? That’s more than the average American household, which averages around 11 megawatt.
Its not super wrong to include external costs as well, but it definitely explains the crazy estimate they got to.
The most misleading part is that this is cherry picking a dense city, and implying all power generation needs to be within city limits. 3 out 11 thermal power stations in Austria are in Vienna, the rest are outside of the main city.
within city limits
it was more a size comparison, i didn’t really mean to say that it has to be within city borders. cables can cross nations, of course.
yeah i included manufacturing because i was like “most big factories are in or close to big cities, because that’s where the workforce lives, so it makes sense to build factories there. and factories need energy.”
ofc small variations in power are a given, because you have things like electricity being more efficient than oil, so you need fewer kWh, and such.

Megawatt-hours hopefully, because if it was 11 MW no wonder we have global warming :D

Megawatt is a rate of energy use/production whereas megawatt hour is an amount used/produced (in an hour). A continuous use of 11MW sure seems like a lot for a household though.
