You do realise with those dirty fossil fuels that an i3 powere by just coal fired electricity is still lower on CO2 in the life cycle than a diesel / petrol powered car.
At 800g/kWh for coal (which includes for minining, trasnportation and not just the burning)
i3 gets about 4 miles per kWh.
Or about 125g/km. All life cycle emissions included.
A 125g/km ICE only gets about 75% of its official mpg figures, which has the same effect on emissions.
So 125g/km for an ICE becomes 166g/km.
And thats just foe the fuel burned by the car, not drilling, pumping, refining, shipping, and forecourt pumping usage which is included in the coal figure.
Hoever the grid isn't all coal powered - and will be zero coal in 10 years as the government announed plans to shut down all coal plant within 10 years. Current grid emissions which should be used for a fair comparison are 350g/kWh. So an i3 on grid elecrtic is
350/4/1.6 = 54g/km.
OR go to Ecotricity or Good Energy and get 0g/km.
Lastly - 50,000 people a year are killed in the UK by the effect of air pollution from transport. Moving the emmssions from exhaust pipes to powerstations is much better than using city air as a sewer. NOX and CO and SO2 and PMs. These are much more highly regulated and controllable when emitted from centralised sources like coal or CCGT powerstations. Flue gas de-suplhursation, SCR NOx scrubbers, electrostatic particulate filters etc.
Then we come to the fact that 97% EVs are charged at home at night. On a grid which currently has 20GW of space capacity overnight. Or enough to provide 2/3 of the dfaily driving demand of the whole UK car fleet. (120GWh per night over 6 hours). EVs make the grid by more efficient - by not having powerstations slowing down from and coming up to generation temperature, which means burning fuel with no power generation.
For the future we'll also have smart grid capabilty so EVs can be switched on and off from charing to balance the minute to minute national needs.
In short... Don't spread myths created by the oil industry!
