I spent some time running some numbers on EVs vs Buses. Obviously, it depends on how the electricity is generated in your region. It also depends on the efficiency of the bus itself. But the general idea is, a bus is less efficient than a gas powered car, but it makes up for it in volume. So, how many passengers would you need to cram into a bus to have the greenhouse gas (ghg) emissions per person equal that of the ghg emissions of an EV driver? For a Heavy Duty Bus, the ghg emissions from... 1 Coal Powered EV = 13 people on the bus 1 Natural Gas Powered EV = 23 people on the bus 1 Solar Powered EV = 215 people on the bus 1 Nuclear Powered EV = 858 people on the bus 1 Wind Powered EV = 1674 people on the bus 1 Hydro Powered EV = 2489 people on the bus 1 Geothermal Powered EV = 3262 people on the bus And since I live in Ontario... 1 Ontario's Energy Mix Powered EV = 1187 people on the bus Of course, different buses have different efficiencies, but even the most efficient bus in my home town (a hybrid bus) is only about twice as efficient as the bus used above, so in my town you'd need 619 people on the bus to bring down the emissions of the bus per person to the levels that I'll be emitting with my Model 3.
