> electric cars usually get 100mpge or better Right, and the mpge metric is flawed, because it assumes a (typically bad) energy mix. 5km driven in the UK is equivalent to 100km driven in Sweden. The former sits at an average of approx. 300gCO2e/kWh. The latter at 15gCO2e/kWh. With electric cars, the ultimate situation is that all of the carbon cost is in the production of the car/roads and maintenance thereof. Which is another issue that can be targeted and mitigated. By contrast the only ultimate hope for a combustion powered plane or car is carbon capture. The 'MPGe' of an electric car in a country with 90%+ renewable energy is like, 1000 or something daft like that.
