i do remember something being quoted...
petrol is about 65% energy efficient (refinery energy costs)
diesel something like 80% ?
where as modern power stations are stupidly efficient even if theyre not carbon netural,
they run big steam turbines as long as a football field attached to generators.
just gotta get the heat / fuel to the station, then its transmission losses from there on out.
probably why councils are looking to subsidize micro generators (home install solar / wind)
and my fireblade according to it can do 12 miles per
litre on average... dont know how much i trust it like,
down hill with closed throttle it bumps up to 17 / 20, thrash it and worst it said was 3.8
think its 4.5 litres to the gallon so...
but im feeling the hike, used to be £15 and id put 16 litres in and fill her up,
now its more like spend £17 and be lucky to get 15 litres!
