Enter your current fuel, quantity and price. Unlock a full side-by-side
comparison across nine alternative fuels — equivalent quantity, total
cost, savings, and carbon intensity per Mcal of useful energy
delivered. The numbers are normalised for combustion efficiency so a
fuel with high gross NCV but poor combustion is correctly discounted.
NCV values from PNGRB and BIS sources. Combustion efficiency included.
Emission factors based on IPCC 2006; biomass fuels shown at stack
emissions, not biogenic-zero.

Equivalent quantity is the amount of each alternative fuel needed to
deliver the same useful energy as your current consumption. Enter the
price you can secure each fuel at to see total cost and savings.
