How much electricity would it take to replace all fossil fuel energy?
Quick estimate
car.fuel_economy
25.4 miles per gallon gasoline
Gas mileage of an average American new car
This datapoint is conformable with [electric_car.efficiency], because the calculator understands 'gallon gasoline' as an energy unit.
Citation:
"The average fuel economy for new 2020 model year cars, light trucks and SUVs in the United States was 25.4 miles per US gallon (9.3 L/100 km)."

ev.efficiency
100 miles per 34.6 kWh
The "gas mileage" equivalent for an average electric car.

World - how much energy might be used if all vehicles were electric
Estimated based on an energy efficiency ratio: typical gasoline car vs typical electric car. Assuming that the ratio would be about the same for larger vehicles.
- Does not factor in the charge/discharge energy losses in the battery.
- Does not factor in the energy needed to manufacture EVs (which might be higher than manufacturing combustion vehicles).
- Does not factor in the charge/discharge energy losses in the battery.
- Does not factor in the energy needed to manufacture EVs (which might be higher than manufacturing combustion vehicles).

(calculation loading) (calculation loading)
- The estimate is based on status-quo total final energy consumption (which is mostly fossil fuels, currently).
- For the transportation sector, we factor in the increased energy-efficiency of electric vehicles (compared to gasoline & diesel).
- For everything else, we assume there's no significant increase in energy efficiency. Why:
- Industry sector: Most fossil fuel use is for producing heat in manufacturing. The efficiency would be the same for electricity as it would be for fuel.
- Buildings sector: Most fossil fuel use is for heating. While it's true that electric heat pumps could be more efficient, the majority of heating is in locations/seasons too cold for any efficiency gain for heat pumps.
- The
(watts per capita)refers to watts averaged over the whole year, or as some would say, "watts RMS". Not peak watts.
The estimate could be an overestimate if...
- increased heat pump usage, cold weather heat pump breakthrough
The estimate could be an underestimate if...
- energy storage losses become significant
FAQ: "Why base the estimate off of the status quo?"
This wiki advocates for decreased energy consumption in rich ("developed") countries. But also, poorer countries might need to increase their energy use. So for lack of more detailed data, the status-quo based "quick estimate" provides a "middle of the road" sense of scale for the amount of renewables that might be needed to reach net zero carbon emissions.
