We thought it would be fun to compare our last two gas cars to our two BMW i3’s. We slid the mileage bar to get a cost of fuel for the BMW i3’s that is slightly less than the EPA sticker of $500 calculated at $0.12 per kWh. This slight reduction is because we drive slightly less than the EPA annual average.
We used the cost of gasoline, which in our area is at $4.00 a gallon
Lastly, we reduced the cost of electricity to $0.08 per kWh which is the levelized cost of electricity for our solar PV system throughout its lifetime. Our solar PV system was installed in 2007 and was paid off in utility and gasoline savings in April of 2012.
We are saving $5,700 a year driving our two BMW i3s fueled by sunshine. That annual savings is nearly the annual cost of one of the BMW i3s.
