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.

....
Current petrol engine efficiency averages 32%,

Nope. 25% You are on about peak.

32% is average for modern cars and that is what electric vehicles should be
compared with, as it is new car buyers who will choose which technology is
used.

....
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.

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

snip out of date stuff about EV efficiencies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, which gives no reason to accept the higher levels of pollution
involved in powering them.
