Double counting of renewable energy
This bug has now been fixed. Thank you.
It seems that wind generation is double-counted in the electricity supply graph: once as offshore and onshore wind and again under "non-thermal renewables". This produces a figure for total energy generation that is 120 TWh/y too high in 2050
