To establish the electricity demand of an electrified transportation sector, historical monthly US transportation petroleum usage,
excluding aviation and ocean shipping, for each sub-region is scaled by the EV efficiency factor above (4x)8. Tesla’s hour by
hour vehicle fleet charging behavior, split between inflexible and flexible portions, is assumed as the EV charging load curve in
the 100% electrified transportation sector. Supercharging, commercial vehicle charging, and vehicles with <50% state of charge
are considered inflexible demand. Home and workplace AC charging are flexible demand and modeled with a 72-hour energy
conservation constraint, modeling the fact that most drivers have flexibility to charge when renewable resources are abundant.
On average, Tesla drivers charge once every 1.7 days from 60% SOC to 90% SOC, so EVs have sufficient range relative to typical
daily mileage to optimize their charging around renewable power availability provided there is charging infrastructure at both
homes and workplaces.
Global electrification of the transportation sector eliminates 28 PWh/year of fossil fuel use and, applying the 4x EV efficiency
factor, creates ~7 PWh/year of additional electrical demand.
