    Is damaging the environment with an electric car really that much better than damaging the environment with an internal combustion car?
    Doonesbury has already answered you above with a graph showing precisely how much better.

    Congratulations, you missed the point... although electric vehicle emissions are lower than ICE emissions, they're still significant. You can't claim you're not contributing to vehicular emissions by driving an electric vehicle. And, as I pointed out in my reply to Doonesbury, you cannot hope to make a comprehensive comparison with a single graph...

    And I didn't.

    I await your detailed thesis then.

    You said that you don't want to contribute to the environmental damage that vehicles have caused, and in the very next sentence you said you plan on getting an electric car as soon as possible. The logical implication of those two statements is that you don't believe electric vehicles damage the environment!

    You'll be waiting a long time then, I've no intention of writing one. Amongst other reasons, we haven't yet had electric vehicles long enough to accurately gauge what the average lifespan of one will be, which is vital as so much of their environmental impact is in manufacture. Additionally, my point was only to highlight the fact that electric vehicles have a non-negligible environmental impact. Comparing the impact of electric and ICE vehicles is not trivial.

    Agreed. The FT article discusses all that. And the chart is a fair summary.

    But of course the devil is in the detail. Have a look at the article and the referenced sources.

    And then we have the sources of the electricity to consider - setting aside the CO2 output in building the vehicle, we have a situation where it is extremely implausible that current renewables could power our huge national vehicle fleet. Therefore a big switch to electric vehicles would simply shift the CO2 emissions from the vehicles to the power stations. In most cases, this would involve more gas (a non-negligible source of CO2) or more nuclear stations, which involve very large CO2 outputs during construction and decommissioning.

    It solves one half of the problem though. Once you got cars running on electricity, you then "only" have to find better ways of generating that electricity.

    The Simpsons Road Rage got it right with their nuclear buses.

    There's certainly infrastructural issues as this scales up. But, for now, there's excess night-time capacity, and every reason to expect renewables to be scaleable too.

    It really depends on how this all rolls out:
    https://www.carbonbrief.org/factchec...-vehicles-need
    "In one scenario, where 100% of cars go electric but smart charging and shared autonomous vehicles help manage the impact on the grid, peak demand could be limited to around 6 gigawatts (GW) in 2050. This is equivalent to 10% of the current 60GW peak demand on a cold winter’s day."

    Moving power production to power stations isn't necessarily a bad thing. You're moving the pollution out of towns and cities, the instant on/off nature of electrical vehicles means energy isn't wasted whilst the car is stationary and efficiency is generally better when burning fuel on large scales than small (although the inefficiency of transmitting energy and charging batteries eats into that). You're absolutely correct in saying that eliminating tailpipe emissions is a long way from the end of the story though.

    There are other issues, such as mining rare earth elements, which are used more extensively in electric vehicles than ICE vehicles. CO2 emissions are an important issue, but not the only one.
