Comment Only 10 year vehicle lifetime? (Score 1) 432
Seems a suspiciously low assumption on max vehicle age. ConsumerReports estimates the average age of all cars on the road is 11 years, and commonly reaching 200,000 miles / 320,000 km in a lifetime.

I presume 10 years is chosen to favour the combustion engine over the electric, which takes a lot of energy to initially make the battery - and for which Tesla at least seems to be working towards making using solar power at its Gigafactory. So lifetime is more like 20 years, and electric vehicles may last even longer given they have simpler parts compared to a combustion engine.
Tesla's seem to be aiming for 500,000 to 1M km lifetime for its latest batteries. Even with a grid based partly on coal, that will almost certainly beat any diesel car, and doesn't factor in Germany's growing proportion of wind power for which charging batteries on a car overnight would be perfect.
Also at the end, a battery stands more chance of being recycled than the 10 to 20 tonnes of fuel burned in an engine over 10-20 years.
