Re: @ bazza

What is the fuel-energy conversion efficiency of a modern all electric car compared to a modern petrol driven car? By that, I mean how much fuel do you need to burn in a power station compared to burning in an IC engine for the car to travel a certain distance.

I realise that the comparisons are complicated by the fact that power stations can burn 'low quality' fuel so they avoid the refining costs and there are, of course, the transport and infrastructure costs of car fuel distribution. Has anyone done a detailed analysis of this?

When I start my car on an average UK morning, the first thing I do is turn the heating full on for a good 15 minutes. In the winter, it's front and rear electric defrost for a good 10 minutes and 50% heating/demist all the time. In the summer, I have the aircon running. I have a feeling that these conditions would invalidate the mileage range claims for any electric vehicle.
