How much does your electric bill go up by (and related - how much cheaper is it compared to filling up at the pump?)

BryanLegend 3y ago
About $25/month in Utah. $0.03/mile

That really depends on where you live, but for me in the EU the fuel/energy cost per km is about 2.5-3x lower with a home-charged EV than with a gas vehicle.

About 40 miles per day of driving, $32.7 electricity for last month.

  In GA I saw my electricity bill go up ~$30/month charging my Model 3 at home and driving it almost every day, about 1000 miles per month. Still cheaper, safer, warmer, and more convenient than going to a gas station.

That depends on the efficiency of your EV, how many miles you drive, and power cost in your area. Something like a Model 3 will typically do <300 wh/mi (gross). At $.14/kwh (pretty close to average for the US), you'd be looking at about $0.042/mile. Energy prices in the US vary between <$.05/kwh (usually off-peak) to ~$.49/kwh (PG&E if you didn't already guess that), so ymmv.

Electric bill goes way up, of course, but it is about the same as gas for me. There have been various fluctuations in both electric and gas prices around me so hard to make an exact comparison. However, my bet is that gas prices long term will only go up and electricity prices ... probably will too, but have a higher chance of remaining lower.

It's kinda impossible to answer without knowing: - your price per kWh of electricity - the car you drive and the efficiency of it - the amount you drive But I'll give it a go with our EV(Volkswagen e-Up). - our price for electricity at the moment is £0.16/kWh - the efficiency is about 3-4 miles/kWh most of the time, it can go as high as 6 miles/kWh in the summer. - we drive about 8000 miles per year. Based on that(and using the most pessimistic numbers for calculations), you need: 8000/3 = 2666kWh to travel per year. At 16p/kWh that's £427 per year, or about £36 per month(which is actually spot on with what I see on my bills). As to how that compares with an ICE.......a petrol Volkswagen UP gets about 6L/100km(6L/60 miles - I'm using that unit for simplicity of calculation so we don't have to mess with gallons. And yes 6L/100km is a big high for the UP, but I'm using pessimistic numbers again). So assuming that 6L/100km, you would need (8000/60)*6 = 800 litres of fuel to cover 8000 miles per year. At the average cost of £1.40/litre it would cost us £1210 in fuel alone to drive for a year(or about £100 per month). So just in fuel vs Electricity alone, the e-Up is about 3x times as cheap as a petrol one. And the servicing is much cheaper, and it doesn't really use consumables like brake pads, they will last a lot longer. On the other hand I've noticed it uses tyres quite quickly(at 10k miles fronts were down to 3mm, which is a good point to replace them), so it might end up being a wash. And yes, we are lucky that - we can charge at home - our home tariff is pretty cheap If we could only charge at public charging points(which at the moment are usually all £0.50/kWh if not more), then that entire saving would disappear, and it would probably be cheaper to drive a petrol version of the same car.

  > It's kinda impossible to answer without knowing: TBH, I'm kind of amazed at the way people talk about electricity. It seems like about twice a year I see a couple of threads on local Facebook groups about how much electricity has gone up. Once after the coldest month, and again after the hottest month. I like to ask their $/kwh, and I've never once gotten an answer. But the US is sort of backward in general. I use an energy coop where how much my car costs to charge is directly affected by how much insulation I have in my attic.

Near zero. I pay $0.01/kwh after 11PM. Costs me $0.80-$1 to “fill up” a totally empty car, which they almost never are at zero.

I have 12kW of solar deployed at my house so haven't had a electric bill in years, so I can't really say. I usually charge about 200-300kWh/mo for my EV which would be about $20-30 based on NV energy's rate plan.

I get ~3.5mi/kWh in my EV with how I drive. I pay ~$0.11/kWh for electricity including delivery. The average US driver drives ~13,000mi/yr. We'll make the math easier and just say you drive ~1,000mi/mo. 1000 mi / 3.5 mi/kWh = 285.7kWh per month. At $0.11/kWh, that's ~$31.43 added to the bill. Gas around me has been around $3/gal for a while. Average US car fuel economy is like 25mpg, which is a bit better than the car my EV replaced. 1000 mi / 25mpg = 40 gallons of gas, * $3/gal gives ~$120 per month. If I had a 40mpg car, it would cost ~$75/mo in gas. I'd need close to 100mpg in an ICE car to get to the same fuel cost.

Diesel car used to cost 12p/mile. EV is 3p/mile. Save approx £90/month. Diesel bill was £120 month. Electricity has gone up by £30.

About $25/month in Utah. $0.03/mile

Diesel car used to cost 12p/mile. EV is 3p/mile. Save approx £90/month. Diesel bill was £120 month. Electricity has gone up by £30.
