I'm not sure but it seems you made some calculation error. 87 TWh = 86 e6 MWh 15 m2/MWh therefore land use is 15*87e6 m2=13.05e8 m2=13.05e8/1000^2 km2 =1305km

15 m2/MWh therefore land use is 15*87e6 m2=13.05e8 m2=13.05e8/1000^2 km2 =1305km2
As a fraction of land 300 000/1305=0.00435 so less than 0.5% will be used for electricity production.
- mdf 4y agoThat 0.00435 is each year, since 87 TWh was the annual use. Multiplying that by 27.25 gets the ~12 % for accumulated percentage by year 2050.
- cycomanic 4y agoOk I think I misunderstood. You were talking about the land use for coal, which I guess you're right would need some accumulation factor (although I suspect it doesn't grow linearly). But if you would use solar or wind you would not, which was the context of the discussion and hence I misunderstood.
