PaulF .... however, as a form of transport and motive power the internal combustion engine was a step-change improvement over the horse (by orders of magnitude) .... what we're talking about here is a 'change' to the same .... EVs won't do anything in actual real world practice that isn't done by IC .... the sole reason for the change is to reduce CO2 .... if that can be achieved by alternative fuels then that's an enormous win .... the environmental cost of replicating a worldwide transport/supply infrastructure will be immense ... there's nothing holy about EV.... it's just being touted as a route to CO2 reduction .... if we could keep the current system but remove the same amount of CO2 then that's a bigger win environmentally.
