I just watched this and thought it was utterly wonderful. So simple and short.
This is all very appropriate because I've just been down to our local petrol station in the Leaf. I filled the little container I use to fuel my lawn mower. It cost £8.46 to fill it.
There it is, £8.46p for that.
When I got back home I did some llewmaths which as regular readers will know are not very reliable, but essentially that's enough money to charge the Nissan Leaf to drive over 500 miles using off peak electricity, which I do.
If I pour this container into a regular small petrol car, (it's clearly a little over 5 litres, the garage I bought if from charges £1.38 a litre) it will travel about 60 miles and I'm being generous. If I poured it into a V8 Range Rover, it would haul that 3 ton beast about 25 miles
Okay, it's going to take me longer to drive that far than it would in a petrol burner, I have to charge up overnight, so it's going to take at least 5 days and I have to drive around 100 miles a day, which I don't. However, the fact remains that petrol, in the UK, with all the tax and production costs, the shipping, refining, storing and pumping is no longer a cheap and abundant fuel.
