CALCULATION OF BIOFUEL PRODUCTION: MATCHING
CULTIVATED AREA TO CONSUMPTION IN NORFOLK by Susan Pollard, BA,
MsC, associate of the Department of Environmental Sciences, University
of East Anglia
This calculation is made using the following
figures and assumptions for 100% biofuel use:
YIELD
Two figures for yield are considered: those
from Sheffield Hallam University and BABFO.
— Sheffield Hallam: 1 tonne or 1,100
litres of biodiesel/hectare.
— BABFO: 1.5 tonnes or 1,650 litres
of biodiesel/hectare.
COUNTY OF
NORFOLK STATISTICS
— Population of Norfolk: 820,000.
— Arable land available in Norfolk
323,082 hectares.
VEHICLE STATISTICS
— Assumption of 0.5 vehicles/head of
population in Norfolk.
— Assuming average annual mileage of
10,000 miles/vehicle.
— Using two levels of vehicle fuel
performance.
— Used Ford Mondeo: 8.4 miles/litre.
— Advanced car performance: 11
miles/litre.
SCENARIOS
— 410,000 vehicles at 10,000 miles/year,
achieving 8.4 miles/litre equivalent to: 488,095,238 litres used/year.
— 410,000 vehicles at 10,000 miles/year,
achieving 11 miles/litre equivalent to: 372,727,272 litres used/year.
— At yield of 1,100 litres/hectare,
total annual yield in Norfolk: 355,390,200 litres.
— At yield of 1,650 litres/hectare,
total annual yield in Norfolk: 533,085,300 litres.
Thus, using the Sheffield Hallam figures, even
with highly fuel efficient vehicles universally in use, Norfolk
could not support all Norfolk's vehicles at 100% biodiesel use.
Using the optimistic BABFO figures, on present
fuel performance figures, Norfolk could barely produce enough
fuel for all Norfolk's vehicles at 100% biodiesel use.
