Julie and I were driving a Volvo S60R and an Infinity G35 before making the switch to the BMW Mini-E, ActiveE, and now two BMW i3's.
Our gasoline cost were around $425 a month for both cars, or just over $5000 a year. Now we supply the power for our electric i3's with a paid off solar PV system installed in 2007. The equalized cost of electricity for us is $0.08 per kWh, so the cost to power each i3 for 12,000 miles is $225, a total of $450 for both cars. That's 1/10th the cost of gasoline.
As the solar PV system was paid off in April of 2012, our actual cost are now zero for the next two decades plus.
A $4500 annual savings multiplied by 25 years will save us over $110,000 without considering changes in the cost of gasoline.
Great post, Peder! Solar is the way to go in residential settings IMHO. I had an Audi A6 Avant before going electric. My gasoline bill was between $200 and $300 a month with moderate driving. The Audi was great, but it was also all-wheel-drive, and was averaging 17 mpg in city traffic
I installed a solar roof on our carport back in early 2013. SolarCity came through as the most affordable option. The kWh cost on a prepaid 20-year lease was 6 cents. This was almost half of the very competitive rate the local utility is offering to its residents. The per-mile fuel cost with this set up is between 1 to 2 cents. Contrast that to the Audi, which was costing me between 14 to 15 cents per mile driven.
Overall, I found that EV ownership cost is greatly offset by gasoline savings.
I applaud those who invest in solar, and I hope to do so myself one day. But I want to note that even without solar, driving an EV can be very economical.
I drove a Saab 9-5 wagon which did reasonably well on fuel, but I still spent $50/week on gasoline (it required premium). When I got my first EV I traded my $200/month habit for $40/month in electricity bills. Even over a typical three year lease, I saved nearly $6000 on gasoline alone. If you factor in not having the buy oil you can probably add another $200 to that. And finally, with aggressive regen braking, my brake pads still had plenty of life after two years!
Unfortunately, the sheer fun of driving an electric car did result in some additional tire wear... there had to be a cost in there somewhere, but at least this one was worth it!
Good point Raz! In many parts of the country (Oregon and Washington as examples) the make up of the grid electricity supply is mostly renewable and very inexpensive. These are great areas to be an EV driver!
My calculations show is about 10x cheaper per mile to run on Solar generated electricity vs gasoline. Our two EVs have been running on Solar for more than a year now, and the savings are over $4000 per year (amortizing the pre-paid solar array over 20 years) for driving 40,000 electric miles per year. A whole order of magnitude less expensive, even at today's "cheap" gas prices. And since I prepaid, the solar cost is fixed, yet the price of gasoline is likely to rise over the next 19 years.
And here in New England the local power companies have just increased the cost of electricity by over 20% due to the totally foreseeable yet somehow unavoidable increase in natural gas prices due to the lack of enough pipe infrastructure to get gas to both power plants and homes for winter heating. So having Solar has mitigated some of that extra cost as well (although winter's Solar output is well below summer's, it still mostly covers the car usage).
2011 BMW ActiveE 34952 miles. (RIP) 2012 Tesla Model S 85kWh (lovely wife's) 62K... 2014 BMW i3 BEV: 32K...
We have fairly cheap electricity here in the south but I have seriously contemplated a small solar array for some time now. I understand that they have gotten much cheaper in recent years so I really need to look into it again.
