> efficiency of the power being generated

That's what I said. Power plant are far more energy efficient than ICE vehicles (around 60%), and the electric car itself is about 90% energy efficient.

> Let's not forget all the inefficiency in the manufacture of those vehicles

Which would be almost the same as an ICE vehicle? Besides that, electric vehicle should last more than ICE ones.

An ICE vehicle transmission has around 20 moving parts in it's transmission, requires oil chance and a lot of maintenance. Electric vehicles' transmission consists of 3 parts and require way less maintenance.

A good battery also lasts a long time. TESLA batteries average capacity after 10 years of usage is around 90%.

Even the brake pads are better conserved in electric vehicles because of their electromagnet regenerative breaking.

> There isn't enough green energy available so we would be using fossil fuels to charge a vehicle so they don't use fossil fuels

From what I recall, the efficiency of gas ICE vehicles' engines is so bad (less than 30% energy used) that even if you used a oil driven electric generator to charge a electric vehicles that would still be more energy efficient overall.

It doesn't matter that we would, for now, have to generate energy via non-green power plants, because the overall energy efficiency would still be better (60% energy efficiency) Also, it's far easier to handle pollution in a single place than to have each individual vehicle having their half-assed filters.

People also forget the energy lost converting oil to gas, and also the distribution itself creates pollution
