.... its about 600 gram of Co2 avoided by each kWh of PV ( in Germany 2010 )
for a 10 kw PV that means approx 10000 kwh x 0.6 kg = 6000 kg each year avoided
the mentioned 1.6 l Golf emits for a yearly driving of 15000 km x 0.120 kg Co2 = 1800 kg each year
Hope i have my calcs right
Billi
.........conclusion? we need lots of PV and EVs now, or as soon as possible, also do not forget the reduction of NOx and particulates, which is estimated to be causing 5 million early deaths a year worldwide!! Desp Absolutely , we have to change our transport system , EV s are one part of an idea People love cars and take it easy to find the funds for them , i wish they would like PV more ... There are about 2 Million new registered cars in the UK , each year , if we take my min of 10000 euro difference to an EV (Golf example ) , that would fund about 20 GW of PV in only one year 8.5 GW of PV installed in the UK at present times

It is difficult to understand why large car manufacturers price electric cars so much higher than equivalent petrol engined models. The marginal cost of each car would be fairly small and mainly due to the battery. They have a very large development costs but that cannot be recovered if they only sell tiny numbers. Adding 50% to the petrol car price is counter productive and can only be explained by them hoping that petrol cars will stay selling for ever. The specialised manufacturers don't have a lot of choice they have to recover all their development costs and overheads if they want to survive. The figure of average electricity co2 emissions is frequently used to say electric cars produce a lot of co2 but there is probably only a small minority that doesn't have PV and those that don't are more likely to use a renewable energy supplier.

Hi, I do not think that the headline price for new cars bears any relationship to the actual price. I know that nearly new Leaf Acenta can be had for about £11,000 with full warranty on the car for 3 years and battery for 8 years/100,000 miles. When my diesel Mondeo became beyond economic repair I bought an ex demo Leaf for £12,000. I took all the paperwork and prices for the old car and basically the Leaf saves £2,000 year over getting a similar car to my old diesel. After three years if I sell for £6,000 the car will have paid for itself. This was planned as a second car but it has become our only car at the moment. I would not recommend one if you do long trips(but there are plenty of rapid charge points around). If you have a daily commute of say 60 miles round trip they are ideal fun to drive and will pay for themselves pretty quickly. There is a view that the finance deals like PCP are used to keep the second hand prices up and distort the market.(but who knows).
Richard

Ive been thinking the same and with some they cant even blame it on battery as thet is priced seperately. Ive neen tempted to propose this as a question to my employers as a research project. I just need to get all the facts together as i see it and get them to view it as something that may influence the car manufacturing industry into facilitating faster take up of low/zero emissions vehicles.

Hi, Just been looking at which energy supplier to use. Ecotricity stay they are the lowest CO2 at 11 g/kWh. I know they build their own renewable generation and/or buy in renewably generated energy. Any thoughts ? is it too good to be true ? Richard Edit from:- http://www.ecotricity.co.uk/for-your-home/britain-s-greenest-energy

oh .... surprise while i write this , its again down to about 135 grams in Denmark http://energinet.dk/flash/Forside/uk/index.html hard to believe , cause it is so calm here in SW of Ireland and a stunner of a sunny day Germany made it close to 30 GW of PV today around lunchtime so about half of the whole el. consumption

Dale vince is an aunt. I'd use another. I'm with Pure planet, but bulb come highly recommended. Also liked being with OVO, but I understand that they aren't competitive any more.
