Modern generating equipment, transmissions, localised power stations,
modern batteries in cars etc, proves that is total balls.

You appear to be talking about efficiency of energy conversion, which is
not the same as the type or amount of pollution produced in converting
that energy.


Energy used to propel n amount of cars of same size x number of miles.
1. Using electric
2. Using petrol.

Also factor in the energy sued in the refining and distribution process
for car fuel too.

That is what it is about. EVs win. They also don't ruin millions of
lungs in towns and cities too.


However, I was not talking about energy efficiency. I was talking about
pollution levels and the fact that electric cars produce around three
times as much as an IC engine.


THEY DO NOT!!! Read again. Don't go on outdated myths.

Current petrol engine efficiency averages 32%,


Nope. 25% You are on about peak.


32% is average for modern cars


Nope 25%.

although most generating plant in use is nearer 40% efficient.


The old stuff.


The majority of the generating capacity is still in the older plant.


It is gradually being renewed, do those figures are false as wehn EVs come
in, in big way the new effuicient and "cleaner" plant will be almost in
place.

Transmission losses in the UK average around 7.4% and the non-zero
charge recharging efficiency of traction batteries is around 80-85%,
although that can drop off dramatically as the charge level approaches
90%.


Not with the Tesla. Read what they have done to make it viable and
double range.


If electric cars are going to sell in volume, they will have to compete on
cost,


The Tesla competes on cost. It is a Porsche type of car, which out performs
and costs the same.

which means that most will use conventional traction batteries for a very
long time yet.


You just made that up, and it is plain you are unaware of battery and power
generation efficiency and pollution cleaning advances.

snip out of date stuff about EV efficiencies


The data was about six months old, but you would have to snip it, as it
showed that electric vehicles have about the same overall efficiency as a
petrol car,


They DO NOT. And those figures do take into account the Tesla which power
management software gets far more out of a battery.
