This article addresses your questions: https://www.carbonbrief.org/factcheck-how-electric-vehicles-help-to-tackle-climate-change https://www.carbonbrief.org/factcheck-how-electric-vehicles-... Check out the "lifecycle greenhouse gas emissions" figures. It's really interesting in how it shows how different the total emissions are depending on which country you charge your electric car in. Also, depending on which electric car model you have, the lifecycle emission improvement over a conventional one might be relatively slim, depending on where and how much you drive it. By and large, electrics are at a substantial disadvantage due to both battery production and fuel cycle emissions, which then gets compensated over time as you drive the car. Edit: There's also this super interesting article on Wikipedia: https://en.wikipedia.org/wiki/Environmental_aspects_of_the_electric_car https://en.wikipedia.org/wiki/Environmental_aspects_of_the_e... which is largely consistent with the Carbonbrief article.

I've seen the graph there and I find one thing troubling: Lifecycle greenhouse gas emissions for conventional and electric vehicles (by country) in grammes CO2-equivalent per kilometre, assuming 150,000 kilometres driven over the vehicle lifetime. That's less than 100,000 miles - rarely do cars travel less than that during their lifetime. Specifically in my country that would mean using the car for ~10 years, meanwhile the average passenger vehicle age is 14 years! As for biofuels: land and water usage are major hindrances. For example you need ~1800 liters of water to grow 1kg of soybean. Sure, you can use waste products for fuels, but they need to be waste from something.

  My gut feeling is electric cars may very well last significantly longer than internal combustion ones. Assuming a 100,000 mile lifetime range smells to me like someone putting their thumb on the scale.
