Why electricity?
Because electric cars are:
small, smart, speedy, trendy, oecological and oeconomical vehicles.
And if loaded with renewable energy they have no bad influences on our enviroment..
is overhhauled since a long time.
With a petrol engine only 40 % of the energie kept in fuel will be used for motion.
The remainder of the energie is losts as warmth, or is swallowed by mobile parts of the machine.
But there is also a substantially better alternative: the electric motor!
It has a very high efficiency and converts up to 95 % of his assigned energy in motion.
It supports power from idling speed, since an electric motor makes it maximum torque
available from starting
That is never possible by an combustion engine. Where torque and power depend on revolutions.
