I don't see why he's basing his calculations on electric cars that only live for 90,000 miles. Electric cars might not make it to 200k - the new models are new enough that we don't know how long they'll be driven - but 90k seems crazy low.
I don't like how he derides the 8.7 tons of CO2 emissions prevented. The average household directly produces 12.4 tons per year - 94% from our cars.[1] If we converted all ~200 million cars in the U.S. to electric, that's 1.7 billion tons of CO2 over the vehicles' lives. To put that in comparison, that's 30% of our TOTAL CO2 use in the US annually.[3] I know these savings aren't going to be yearly, but the point is that 8.7 tons is nothing to scoff at.
The author also totally glosses over our reliance on fossil fuels, rising oil prices, improvements in manufacturing for electric cars, and the lower cost for fuel to consumers.
