Hi Billi, Looks like things are coming into place at last. That would give an EV 34g/km. Or comparing eggs with doughnuts allowing for emodied energy it would be 64g/km. Not bad for current EVs.

Seems very good, but how do they apportion the CO2 from the CHP systems?

Ok you calculate in cars ....  , fair enough  my currency is Euros , i still believe , that the luxury of electric cars ........................... has to be invested into the Grid first

Hi Billi, I have been looking at electric cars a lot especially how much energy they use. Something that struck me was a quote from Elon Musk :-
“You have enough electricity to power all the cars in the country if you stop refining gasoline. You take an average of 5 kilowatt hours to refine one gallon of gasoline, something like the Model S can go 20 miles on 5 kilowatt hours.”
So I am thinking will EV's be a big win win situation ?
Attached is someone else take on the situation.

Richard , a VW eco up with under 80 gramms per kWh is about 12000 euro
if Elon Musk ever wants to manage to built cars in a price range like that , then he is very welcome to join
for the time beeing , i advice people to invest in PV and drive other cars
i did a few calculations (based on my silly brain ) ... the result was that we are bettor of driving small petrol cars and safe some cash for other ideas

The point about electric cars is that they are very efficient - motor efficiencies of >90% vs <50% for IC. AND the motor only runs when you need it to. In traffic, when stationary, there's no idling, no electric consumption at all.

But even so there are cheap EV cars that are competitive financially. I find it hard to get information on CO2 emmissions comparison though. ... In countries like Germany with an average Co2 per kwh over 550 gram its close to impossible do drive more Co2 friendly with an electric car ( but i ignore the other emissions) Anyway a electric Golf in Germany will emit 103 Gram per km , an 1.6 l Golf about 120 gram , battery production emissions is a factor as well ... The price difference of both is a 10 kw PV Billi

Similar CO emissions for both but local particulates in populated areas with the ICE car. I trust monitoring of power station emissions more than millions of catalytic converters and particulate filters which will receive minimal maintenance during their life and by all accounts do not seem up to the job when installed on some vehicles.

.... 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

.........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

something that doesn't seem to get much of a mention with EV's is the energy required to keep the passenger space warm Surely this is a fair power drain so even in stationery traffic theres a heater running when external temps drop below 18c ? Or will future EV's have a little windy smith wood burner where the gear shift used to be ?
