I have a similar problem and use the same argument. Since all my cars are older and I have never bought a new car, I also point out I have never contributed to the large carbon footprint of manufacturing a new car. Every time someone buys a new car they are contributing at least 5 Mg of carbon dioxide into the atmosphere, and perhaps twice that if it is an electric car.

I have been criticised in the past for owning 6 cars (mostly classic) claiming that I am harming the environment or even the attack of ‘denial’ regarding the subject. I have had to remind such people that because I have 6 cars only one of them can be driven at once. There’s an answer for you to borrow if you should ever be criticised in a similar manner ;-) On 17 May 2020, at 11:14 pm, Brian White <[email protected]<mailto:[email protected]>> wrote: I have ten cars, not one of them electric. :) One 1.5 liter 4 cylinder One 1.6 liter 4 cylinder Two 2 liter 4 cylinders One 2 liter 4 cylinder 16v turbo One supercharged 3 liter V6 One 3.4 liter V8 One 4.2 liter V8 One 4.4 liter V8 One 4.8 liter V12 (18.5 liters of oil and 120 liters of fuel) On May 17, 2020, at 14:59, John Nichols <[email protected]<mailto:[email protected]>> wrote: Entropy is a wonderful thing From: USMA <[email protected]<mailto:[email protected]>> On Behalf Of Martin Vlietstra Sent: Sunday, 17 May 2020 3:08 PM To: 'Michael Payne' <[email protected]<mailto:[email protected]>>; 'USMA List Server' <[email protected]<mailto:[email protected]>> Subject: [USMA 1402] Re: Talking to people about metric One other advantage, particularly in city traffic is regenerative braking. When you apply brakes in a petrol-powered car, the energy that you used to get up to speed is thrown away, in a vehicle with regenerative braking, it is “pumped” back into the battery.

The car has a 66 kW motor. Low cost of operation is one of the advantages of electric vehicles, apart from no maintenance (oil, filters, plugs, etc.) the cost of operation is very low and even cheaper in traffic where the consumption is the inverse of internal combustion engines. I’ll attach a couple of pictures, as you can see I’ve only done 65 km this month with the lockdown. We can do more traveling now we’ve opened up a bit from the 11th May. I reset the data the 1st of every month. <image001.jpg> <image002.jpg> On 15 May 2020, at 17:59, Martin Vlietstra <[email protected]<mailto:[email protected]>> wrote: Mike, Surely you mean 7 kWh/100 km? (Also 12,5 to 16 kWh/100 km). Your running costs show one of the advantages of using metric units. A petrol-powered small car uses about 4 L/100 km (larger cars typically 7 or 8 L/100 km). (I will not quote the mpg as that would means specifying whether I am talking about US or Imperial gallons). A litre of petrol is typically €1,40 so the running cost of your electric car is one quarter that of a petrol-powered car.

The numbers you give show a consumption of just over 7 kW/100 km, this is very low compared to my Renault Zoe (the same platform as the Nissan Leaf) which averages about 12,5 to16 kW/100 km which give me a cost per 100 km of about €1,30. Also charging on the cheap rate which the car does automatically.

What he says about liberal-right-wing-left -wing-fake news-etc is absolutely correct. The best way to convince someone about the usefulness of the metric system is to gently point out how simple and easy to use it is, and mention that it is used without a second thought everywhere else on our planet. Unfortunately, with our miserable political divisions and now the virus, we on the metric cutting edge are pretty much way out on the back burner for a while. But it would sure be nice to hear about 2m social distancing for a change! On another point, Tesla vehicles have a computer readout showing kWh used since the last charge, per trip, or overall. There is also a Wh/km rate display for the same periods. One vehicle I have information on shows 2200 kWh used for about 15500 km traveled overall. At a $ 0.12 /kWh rate for home electric vehicle charging in northern California (starts at midnight), the electricity cost is $264 or just $ 0.017/km. All the driver has to do is select metric instead of miles on a preferences screen.
