My concern with it all is the pollution involved in making the batteries. Yes the car themselves are Eco Friendly once built.
but are they? no one actually knows exactly where there power comes from (ie which power station) so it could be a huge dirty coal plant or some eco friendly wind farm somewhere.
as for the battery life and running costs, Nissan claimed, when they were launching the leaf, that the batteries (at a cost of £5k+ from memory) would need replaced something like every 5 years. now, taking the cost of fuel (and obviously its storage in the case of batteries) I did some pretty basic (I'm not a complicated sort of bloke) maths breaking it down to the costs for the average 10k miles per year car user and it worked out that at 40mpg there was still a slight cost advantage over a pre set cycle (Nissan were claiming you would be able to pay for an amount per week/month to 'hire' the batteries, so the cycle would be however long you kept the car under these circumstances) with a regular car, over the cost of running a Leaf, ignoring the range issues and time to recharge them.
then if I were to take into account the cost difference between the Leaf (they were claiming £20k to buy at the time) and its petrol/diesel equivalent (size wise) the Nissan Almera (or you could have gone for a focus, Astra or any competitor) with similar (according to the info I had at the time) for about £7k less. so poor range/recharge rates, £7k more to buy, daily running costs pretty much the same, ok regular engines need a service now and again (2-3 over 3 years) which WONT (unless its MB dealer prices) cost £7k between them. THAT is the main reason theyre not taking off as fast as they could.
