From what I've read, the Roadster can do 393km on a single charge. The batteries are also capable of storing 53kWhrs of charge. Making an assumption, this gives 53kWhrs per 393km. This got me curious so I did some very crude calculations from a bit of research: Generally speaking, burning 1kg of coal to generate electricity produces approx 2kWh, so 26kg coal is needed to produce the required 53kWhrs. Burning 1kg of coal produces 1.83 kg of CO2 (This is actually variable and depends on the amount of carbon present in the coal). To get 393km out of a car that does 13L/100km, you need 51L of petrol. Burning 1L of petrol produces around 2.2kg of CO2 (Depending on octane etc). So to cover the same distance, the electric car generates around 48kg of carbon dioxide, and your falcon generates 112kg. So while all the hippies go and masturbate over how electric cars are so good for the environment etc they're not fantastic, especially once you consider environmental impact of producing (and disposing of) the nasty evil Lithium Ion cells. I know I didn't take into consideration the CO2 impact of refining the oil into petrol, but when you consider only about 40% of crude oil is made into petrol with the other 60% used for other fuels/hydrocarbons/plastics etc I guess you could offset that by 40% to be fair, and mining of coal is not exactly a clean process either. Your average dragline will use about as much electricity as a small town will.
