The other part about fossil-fuel-consuming vehicles is that, as I often put it, you get a maximum 25 per cent efficiency in your internal combustion engine, and that internal combustion engine is consuming oil, which is a non-renewable, precious and valuable resource.
L'autre aspect de ces véhicules, comme je le dis souvent, c'est que le rendement maximal du moteur à combustion interne est de 25 p. 100 et que ce moteur consomme du pétrole, qui est une précieuse ressource non renouvelable.
