EV's..... not good.

[STEVENSON-KAATSCH]

Simple stuff. Petrol cars, around 30% efficient (30 out of every 100 units of energy makes it move along). Humans, around 30% efficient. Mains electric, about12% efficiency between power-station and outlet socket. Dunno the mechanical efficiency of electric cars, but even the best batteries currently available are pretty crap, they leak electric out and go flat faster than a tank of petrol dries away certainly. Lets be generous and say they are 80% efficient which means 80% of 12% is how efficient electric cars are. Electric is made from either burning fossil fuels to make steam to drive turbines... or nuclear reaction to do exactly the same..... or various windmills and the like. The 'clean' power from the windmills is not much in the great scheme of things. It is unreliable and the NIMBY's won't let us smother the country in them for some reason. Nuclear power is lovely until the generator is worn out.... then it's a multi-thousand year nightmare. Filthy old fossil fuel is the current only practical option until we've invented ambient super-conductors and an artificial copycat of a leaf to convert carbon dioxide back into oxygen before we have to vent it into the atmosphere. So, as I said, EV's not good.
