have you heard of anyone buying a replacement battery for their tesla?I think to be really fair you need to consider the cost of the battery for the EV. They don't last forever. Hopefully replacement batteries will be less expensive in the future.
There are multiple Teslas with north of 200K miles on the odometer now. According to this article on Electrek, degradation is approx 5% at 50K miles, 8% at 100K miles and about 15% at 200K miles:I think to be really fair you need to consider the cost of the battery for the EV.

Thanks for the feed back. I forgot to document where I got the 3.4, wish I had saved the link.It basically looks right to me. Here's some nit-picking if that's what your looking for.
Might want to add 5-10% to the electric for efficiency loss through charger.
Not sure about the gas mpg, but I don't think most people get 3.4 mi/kwh in the real world with the model s - you'd need a light foot. I'd personally use 2.9.
Probably another kwh /day in vampire losses.
Good luck!
If you're trying to make a point, compare more comparable cars .... a TDI versus a Tesla?
Pick a sedan of similar size/power/weight/category... not an "average" car or an economy car.
A similar class car has worse MPG, and makes a stronger point for electric.
If you own a TDI, well, then... you can see you're still ahead.
For your 13 cents / kW... is that the all-in delivered price of electricity on your bill?
Often the energy sellers will quote a " 7 cents kW" price in their advertising... but then you see the "delivery charges" and other fees on the bill when it arrives... can double the per-kW price of the energy itself. I don't know why energy utilities can get away with that kind of crap.
I did the maths for myself once, roughly and came up with a ratio that I use when people ask...
"It costs about a quarter to a third of the price of gas to drive on electricity..."
Your numbers are in line with that.
Then I follow-up and say immediately this:
"but that's not enough of a difference to justify the cost of buying this Tesla. It won't payback for the life of the car on fuel alone."
This leads into other EV discussion.... "I'm happy knowing that I produce zero carbon while driving the car"... (notice words carefully chosen here - to see if they then regurgitate the argument of it taking carbon to produce the electricity)
.. and "I enjoy not paying road tax that is added into the price of gas at the pump".

Makes it easier for me - electric is only 10 cents, I drive 25k miles/yr and my last car was only getting 14 mpg.
Do they still sell TDI in US? Funny how that car went from being PC to similar to driving a huge SUV. I always admired its range.
there is always some loss converting between ac & dc. As I understand it, newer teslas are a little more efficient. Also, the efficiency is better at higher power (there is more % loss charging on 110 vs 240, for example).Thanks for the feed back. I forgot to document where I got the 3.4, wish I had saved the link.
Is the 5-10% loss through the charger just the way it goes for electricity or is that something Tesla can improve.
Will
When you factor in the higher cost of the Tesla over the TDI you are really loosing money and not saving in your yearly expenses.
Appreciate any feed back
