Forgive my naivety but to charge these new electric batteries shirley some fossil fuel has to be burnt or the odd isotope has to be cracked somewhere?
Just because it's further down the line and the electricity appears noiselessly at the flick of a switch, doesn't mean we won't still be paying for it and carbonising the atmosphere.
And I wouldn't like to be mid channel when the volts and amps ran out.
