Hello,
The question of comparing fuel consumptions is an uneasy one.
For modern aircraft, I think it becomes easier, as for each generation or version of engines and aircraft, the fuel consumption per passenger/distance is (slightly) reduced. Not a big deal, as there is no infinite number of manufacturers. In comparable circumstances (full passenger load, same altitudes, same distance...), the fuel consumption per passenger of the A380 will be better than of the 747-400, but worse than that of the 747-8, etc... and will amount to some 14 nautical miles per passenger and per liter. Also 30 liter per nautical mile, for less than 400mt total, more than 100 times less than the dharl's ship, at only 3 times the fuel rate.
So, the color of turbine fuel is in no circumstance "green"! (but light yellow), and heavy fuel oil is "greener" (almost...) thanks to maritime transport.
Regards,
Luc
