claim: When South Australians buy electricity at $14,200 / MWh, they are paying the equivalent of $400 a litre for petrol.
evidence: The affordable electricity retail price ( 860 kcal / kWh at 75% input electricity to shaft power efficiency ) to replace petrol ( lower heating value 7693 kcal / litre at 33% fuel energy to crank shaft efficiency ) is 19.06 Rs / kWh.
