“The feasibility of long range battery electric cars in New Zealand”, Mike Duke, et al, Energy Policy, 37 (2009), pp 3355-3462
In summary: Ffs, just get on with it.
Seriously, just get on with it. Caveats:
- Yes, we’ll need more renewables, but not that many more.
- Yes, this will put strain on the transmission grid, but electric cars mostly will charge at night when most factories and offices are switched off, so no prob.
- A range of 150 km per day will work for urban dwellers on ~98% of their days. So maybe 6 days per year they’ll want to hire a fossil fuel car.
- Yes, electric cars will be less useful for rural dwellers, meeting their transport needs on only 95% of days.
- The running costs are tiny, but the up-front costs are more than a petrol car. It’ll be cheaper overall, but you could have a reverse poverty trap, where people on low incomes can’t afford the up-front costs of an electric car, so will end up stuck with a fossil car and paying more overall.
- If we do what we normally do and wait to buy second-hand versions from Japan, then we’ll be waiting a long time.
So we should get on with it.
