Additionally, Tesla's relatively cost-effective (and hence energy-efficient) manufacturing of battery packs will bring this down, probably to well under 100 kg.

Another way to look at this kind of thing is to directly convert dollars into CO2. This is assuming that all "economic activity" directly or indirectly uses energy, and that most energy is fossil-fuel based. This is actually a good way to estimate the maximum energy usage, because energy is fungible but businesses aren't a charity. They'll sell you something for the energy cost plus profit, but not less than the base energy cost.

A Tesla replacement pack costs roughly $15K and a matching solar panel to charge it would cost about $10K. That's the equivalent to burning $25K of a fuel such as petrol. Even before the pandemic, my fuel costs were quite low at about $1.5K/year, so it would have taken nearly 17 years to break even! An Uber driver might be able to achieve a net benefit for the environment in under a year.

EVs are not a panacea. Instead, we should look more into collective transport, better urban planning, more bike lanes, etc. Cars are a cultural issue, and more cars won't solve the problem, whether electric or not.
