    So...some ICE (Diesel) cars can get near 100Mpg (UK) The Peugeot 208 1.6 gets you 94.1Mpg (UK)

    Over at:

    Fuel Calculators » Fuel-Economy.co.uk

    I entered
    Miles: 10000
    Mpg: 94.1
    Fuel Cost: 107 pence/litre

    That journey would cost you £516.93 over 10K miles. (Assuming that you always get that figure. Of course you won't but there are just too many variables)

    That's basically also saying that 1 mile costs 0.051693p in fuel. Again...a single mile trip will cost you a lot more than that, but

    Assuming a cost of 15p/kwH price for the leccy, and assuming a battery range of 215 miles with a 45Kw battery, I presume the following maths is correct

    0.15*45=6.75
    6.75/215 = 0.0313953488372093 per mile
    0.0313953488372093*10,000 =£313.95

    Saving you £202.98/year over a diesel or around 60% of the cost of diesel. Though with the flip side also being the cleaner fuel than diesel considering the NoX emissions

    As well as an Mpg of 154.94 (Using trial and error, on the fuel calculator to get me £313.95 using the above fuel cost)

    I assume this is correct? So assuming that the Tesla Model 3 uses a 45Kw battery, it would get the equivalent of around 155Mpg, and a cost of around 3p/mile?

    This of course is using the leccy during peak hours, so one would assume that charging during off peak hours, at a cost of 7.5p/KwH it's more like 310Mpg or about 1.5p/mile?

    Of course this is UK figures but in the fuel calculator, you can just pop in US figures, and well I guess you'd just have to change the £ to a $ sign

    your biggest issue is the type of driving. that diesel figure drops like a lead balloon around town, and ev goes up on the highway. everyone has to plug in their personal/regional info. and that's not even taking into account the cost of breathing diesel fumes.

    I understand that, but I work on the theoretical maximums mainly because it's the easiest way to go about it :D

    now that we solved that, let's tackle the electrical production fuels.:cool:

    electrical...production...fuels? Well... coal is still the main thing you use in the USA

    The UK mainly uses gas and nuclear
    G. B. National Grid status

    France also sells us nuclear here :)

    we have plenty of gas, the coal is a political thing i believe.

    Yeah. I noticed that coal is used a heck of a lot less in California compared to Alabama - It's a "but what about the poor?" argument, even though the poorest are most adversely affected by diesel fumes and coal plants. In the UK, we've shut all coal power plants down. Well, they're used in the winter but that's about it really

    i think it would benefit everyone to get off coal (except the coal magnates) and retrain the miners to a life giving profession. farming for instance.

    well, that map is a bit pro-EV...they are saying EV cheaper than an average 25 MPG car, not a Prius. Longer discussion elsewhere here. Not to mention taxes higher on gaso.

    Yes, as I said: generalized view of averages.

    Yes we are under $2/gallon in some spots and lower by my guess for Feb_2017. So a 50 MPG Prius cannot be beat in many states. However, Plug_in advocates like to compare to 25 MPG average US car. Meanwhile advocates use hypothetical best possible Kwhrs efficiency for BEV, since BEV has a public relations advantage in that the actual amount of electrons used to charge BEV's is not accurately measured, so that leaves room for claims of superb BEV efficiency in all weather conditions. Ask me if I believe it.

    $2 a..GALLON! That's 3.75 litres or..$0.53/litre. Wow! Even if the exchange rates were to hit 1/1 here, that'd be a mere 53p/litre, but I don't know what your average salary is over there. Also, that's cheaper than it is in Pakistan! In other news, I miss the higher exchange rates. Bloody brexit

    The efficiency of coal power plants (or really any power plant) could be doubled if the hot water from the plants would be exported to nearby houses and businesses instead of being dumped in the river.

    The winter stench from individual houses could be eliminated but no political will to do it here in the USA .

    Our local powerplant is surrounded by nearly 1000 homes, 5 large industrial companies, a mall and dozens of individual stores in a 10 mile radius.

    All have city sewer water and have been built in the last decade or two.
    Three pipes instead of two to make it happen (or two water pipes instead of 1 water and natural gas pipe)

    Imagine if we lived in a world where we efficiently use resources?
    Too bad only Europe re-uses waste heat.

    Yes CoGen can make great sense, but we don't do too much in the USA. We do some however, especially in industry areas.

    Normally CoGen requires a smallish power plant, because there so much waste heat, there is no place to put it, if you have a big power plant. U.S. Utilities normally want to build the world's largest power plants, for profit maximization, so therein lies the rub. For me, smaller is better, but that means more smaller plants all over the pace. Heading in that direction with solar/wind.

    The bold type is simply wrong. Most advocates use a rounded 3miles/kWh or use the EPA kWh/100 Miles value which is the power from the wall, not the battery.

    And why wouldn't you compare against the average car when trying to talk about nationwide numbers rather than a best case?
    True, this doesn't give specific info, but it isn't supposed to. It is a generalization.
    If you want more specific info, use a study such as the State Of Charge report by the Union of Concerned Scientists.

    If you want information on your specific case, compare your fuel efficiency in your car to the efficiency rating you get in a specific EV, charged using a specific EVSE, at the rate you charge it, and driven as efficiently as you drive.
    That information will never be in a report, and expecting it to be is rather futile.

    It is what that steam pipe that blew in NYC was used for

    The Union of Concerned Scientists used the efficiency of the Leaf and Model S, which were the big sellers at the time of the "Cradle to Grave" report. For average car fuel economy they used 29mpg, which includes the Prius family. Trucks and SUVs were left out, because there wasn't a BEV version available at the time. It uses EPA ratings. While this means we don't see the hit EVs take in freezing temps, also don't see the not as bad hit ICE cars take in the same conditions.

    A redo with cars available now would be nice to see, but I expect it will get worse for the ICEs. The efficiency loss of the Model X to an average will be balanced by the addition of the i3. Then the ICE mpg average will drop from the addition of those SUVs.

    Tbh in the UK, we've effectively stopped using coal altogether. It's there as "emergency" power these days. See here:

    G. B. National Grid status

    Tbh, when even "enemy" countries like Russia pump money in to France and their nuclear fusion ambitions, that says a lot - the world is ready to ditch oil.
