If we are talking solely about power usage from the grid then, even in the worst case scenarios, EVs are much cleaner than ICE vehicles.

For example, the average gas car emits around 441g or about .972 pounds worth of CO2 per mile.

For comparison purposes, let’s take the most popular EV currently sold right now which is the model 3 long range as our test case. This car in the worst conditions (cold) goes around 240 miles (a far cry from the 300+ it’s advertised to have I might add) and uses 72kWh to do so. This means, in the worst case scenario, the car is using .3kWh of battery per mile.

Now for the power plant. Let’s use coal as our power source. Coal power emits approximately 2.26 pounds of CO2 per KWh produced. If we take our numbers from earlier, then the model 3 driving in the cold results in .678 pounds of co2 per mile being emitted at the power plant if it is charged using coal power. This is still about 30% less emissions than the ICE vehicle per mile. If the car was powered by natural gas then the percentage grows to around 70%.

Of course there are other factors involved such as other pollutants emitted during power productions (especially when burning coal). However, a lot of these are also produced by ICE vehicles. It’s much easier to have centralized sources of pollution rather than millions of them spread out over the place. Another thing to note is that EVs take more emissions to produce, but is mostly offset over the lifespan of the vehicles due to their low maintenance. EV batteries can also be recycled, though they are usually used in power storage instead of new vehicles.
