Gas prices

[TruckDaddy]

My electric rate is 9.3 cents/kwh. So 20% to 80% of the model Y battery is $4.19. (Don't let it get too low, nor too high for daily driving.)

This works out to about 195 e-mpg compared to gas.

My first year was free at superchargers on a promotion Tesla was doing at the end of 2020. I only managed to get 20K miles driven, a lot on Uber.

Normalizing to current price per gallon?

Today I put 24 bucks worth of gas in my Nissan van. It had half a tank in it.
Two years ago I could fill it up from bone dry for about 18 dollars.
Yesterday we filled the Diesel Pig up at the National Guard base where military and retirees don't pay the Alabama fuel tax (about 20 cents).
It had a quarter of a tank and it cost 150 bucks to top it off.
That CT can't get here soon enough.

Kinda along the same lines but not exactly, my wife is WFH and had to go into work. She got paid mileage and got to top off the charge on the car at work. If the cost is less than zero, it does some wonky things to the math. Of course, WFH beats math so it's all just fun thinking about it.

For what it’s worth, every dollar increase in gas prices is a $600/ year increase in the cost of operating an ICE vehicle. So the cost advantage of an EV increases by about $3000.

My wife's cousin charges his tesla at the free city level 2 charger a couple times per week and walks 2 blocks home......some people are so cheap. It kind of makes me chuckle but wonder about people at the same time.

All I know is that I can't afford both a M Y and C T, but I will have that truck OH YES, it will be mine...

If local gas price matches $4.19, I'm getting the 195 miles at the same rate.

Let's pretend gas was double at $8.38 locally, and my electric rate is still 9.3 cents/kwh, then I would be getting double the miles at 390 mpge before I spend $8.38 in electricity.

I set up Tessie to compare my mY to the f350 it replaced and it's gotten insane. MPGe is a kind of messy metric, I broke it down to cost per mile for analysis and it's way more sensible. That said, here's what Tessie reports for just this past month:

Ugh, okay, I kinda see, but not quite. Lemme run this on paper to see if I'm following. I'm going to end up sounding like ajdelange for a moment. x-x;

So I pay alot more for my electricity, 31¢ a kWh; and a bit more for my gas (just checked on gas buddy, I have never paid this much), it's $5.19 at Costco (ten miles away) and $5.99 at the local full-service (less than a mile). Letsee, I get 31.5 mpg in the Mazda and about 10 miles per kWh on my Zero (varies wildly, honestly, by temperature and speed)... which is essentially 337 mpge (miles per gallon energy equipment).

but miles per gallon cost equivalent...

gas gallon cost / miles per gallon = cost per mile
$5.99 / 31.5 = $0.190

Kilowatt hour cost / miles per kilowatt = cost per mile
$0.31 / 10 = $0.031

Now of course, a gas car has a cost for oil and maintenance per mile that's a bit higher. Tho with my low miles it's scarily similar. So I'll skip that part...

But we're looking at how many miles I could go on the same cost of a gallon of gas, instead of being

kWh energy per gallon / miles per kWh = mpge (miles per gallon energy equivalent)

we want

cost per gallon / cost per mile = mpgc (miles per gallon cost equivalent)

so...

$5.99 / 0.031 = 193 mpgc

Aha! Okay. Sorry I wasn't following there for a moment. ^-^

I suppose we could make a miles per dollar equivalent (mpde), too. How far a dollar will get you from home.

miles per gallon / dollars per gallon = miles per dollar

miles per kwh / dollars per kwh = miles per dollar

which would be 5.25 mpde for my Mazda and 32.25 for my Zero.

So I have to carry or replace six trips with my Mazda before it becomes cost equivalent. At least in fuel. Not time ^-^;

I'm curious how many miles were driven in that month, to come up with those dollar amounts. Has the model Y been capable of handling all the jobs you needed to do? I remember prior to ordering your Tesla, you were voicing some concerns about how your customers would react to you driving a Tesla. How's that going?
BTW, I saw where Ford is talking about selling E-Transit vans. The one problem I see is they are limited on range. With the amount of miles you drive, I can't imagine it would work.

Here's the updated numbers from today, Tessie is awesome for this, btw. Works out to about $0.058 per mile in the mY compared to $0.37 per mile in the truck, not including oil changes and fluids.

As for the reception, I've been to over 100 customer sites and only one person gave me guff, everyone else seems to love it and can't get over just how much I can fit in the trunk.

Wowzers... that's REALLY high. Even at my peek rate in hot Atlanta GA, my cost is only 13.5¢/kwh. Totally free between 12-6am on their EV charging rate plan. What city are you in that charges that high of a rate on electricity??

 

[TruckDaddy]

I live in a county that has to use the electric coop, no choice.

In my previous location, it was free overnight electricity, running the AC all night, drying the laundry, running the dishwasher, charging cars, etc. My monthly bill was about $50.
