Actually all of the energy you put in a car is converted to heat (assuming your start and end point are at the same height).

QuoteActually all of the energy you put in a car is converted to heat (assuming your start and end point are at the same height).Yes, that's nearly 100% true.
But a gas car needs to convert 8x more energy to heat to be able to travel the same distance as a BEV.

I can't see why you keep telling these kind of fairy tales.
TCO is what counts and that is where EVs completely suck in the long term (when free charging goes away and the costs of upgrading the infrastructure become clear).

Something else I read the other day was Tesla is no longer providing home chargers with the vehicles.
The cost of a charger in the US and having it wired in on a HD circuit is said to be 2 grand. I would imagine in the US thats a significant part of the fuel cost for an average vehicle for a year straight off.
And not just that... there is a whole flurry of electric cars about to hit the market. Who guarantees me that (if I buy one) I can still charge it from a public charging spot 10 years from now? And how about 20 years from now?
Will there even be a public charging infrastructure in 10 years or are the EVs which are still around only usefull to those who have a charging space at home and like to have a short distance roundabout? It will all depend on demand and popularity.
My prediction is like most technology's, there will certainly be an early bun rush particularly due to the over hyping and green washing. Wether they live up to peoples expectations and they take to them after there are enough out there that everyone knows someone that has one, will remain to be seen. There ill be a myriad of problems with the things due to nothing more than human nature and resistance to change to be fair but then the real dislikes and limitations will show up and it will depend on how people take those.
It'd be pretty certain though that if the things do not turn out to be cheaper to run, they will not be looked on favorably.
There is also the thing of cultural preferences. I predict EV's will do far better in some places than others. Power pricing, range and load carrying will be big factors. F-150s if they have these things which will probably have to be the equal if the IC's at least in carrying and towing should be OK if all rural US is now electrified.QuoteAny car you'll buy needs a supporting infrastructure if you want to use it for long distances.
And this is a big sticking point I see as a problem. Charging up hundreds/ thousands of cars at holiday time is going to be a big hurdle.
As our main holidays are in summer time when power is already short, loads of cars all wanting to charge up at once is going to require massive additional power. We are expecting blackouts due to power shortages over the next few summers at least and the worry is there is no planning for an increase in infrastructure to address this. These things take a Minimum of 5 years from planing to first siod being turned so maybe 10 years before anything is in place.
I have been putting in generators and more solar panels but I think I'll start stockpiling them while the things can be had at a reasonable price.
Could be a real good investment for the future to have them in reserve and sell them off as well.
Looking at the article I linked to above, the true fallacy of EV's being cheaper to run comes out:
From this week, the pioneering electric car-maker from California will increase the average price of charging at any of its Australian and New Zealand supercharger stations from $0.35 per kWh to $0.42 per kWh, or 20 per cent.
In reality, the price hikes mean it will cost an additional $5.25 to fully replenish a Tesla Model S with a 75kWh battery (claimed 490km range), or $31.50.
....blahblahblah
If my car was electric and I charged at home on the nightly rate it would cost £0.03/m, I am currently paying £0.15/m in petrol, fact and end of!
electric apparently uses around 250Wh per mile, the drive train is around 90% efficient. Internal combustion engines as the name suggests make more heat and are more wasteful at 30-40% efficiency. After that you can argue about your tyres or whatever but the differences between an electric drive train and ICE es massive.

Overnight we can pay 8-9p/KWh. yes the cost of the fuel is important.
Overnight we can pay 8-9p/KWh. yes the cost of the fuel is important.But that is likely without taxes and distribution costs. These usually are hidden in the fine print. All in all the difference is minimal.

Costs are. But if you insist on comparing efficiencies you must factor in the source of the electricity. And then things turn really ugly.
Also your electicity price seems way to low. I think you forgot to add taxes and distribution costs. According to this graph electricity is even more expensive in the UK compared to the Netherlands:
From: http://euanmearns.com/energy-prices-in-europe/
If you do the math with these prices you'll see an EV is on par with the average ICE car when it comes to cost per km IF you charge at home. An efficient ICE will be cheaper to run! If you have to rely on public charging infrastructure then the price per km for the EV will at least double.
In the end it is all about costs.
Just check your bill. I'm paying around 23 eurocents (17p) per kWh (which is about average for the NL) and all lists I can find show electricity is more expensive in the UK. Something isn't right.

I pay 18p/KWh because I use a more expensive supplier (my choice), i know what i pay. You are just peddaling BS to make a non argument. Infact i pay way less than that because I generate my own anyway and once the cost went over 12p/KWh the battery systems become viable. Daily connection charges which you will pay anyway because your house needs power anyway are under 20p/day.
