Compare Electric Vehicle Fuel Costs

Quote from Graeme Weston on 1 October 2023, 5:23 pm

Petrol and electricity are nearly the same price in energy terms.

One litre of petrol contains the energy equivalent to 8.9 kWh of electricity. 

1L petrol @$2.90/8.9 = 33c/kWh

Electricity from the grid = 32.5c/kWh.

The difference is how an Internal Combustion Engine (ICE), Plug-in Hybrid Electric Vehicle (PHEV) and Battery Electric Vehicle (BEV) use that energy. 

ICE is only 17% efficient at converting the equivalent energy into motion, PHEV 54% and BEV 90%. Hence the different distances travelled on the same amount of energy (in this example 60 kWh).
