Sungas Is The Least Expensive Transportation Fuel

Gas at $4.00 per gallon, Electricity at $0.08 per kWh, 12,000 miles per car.

Just pinch me!

Here is a handy dandy calculator from UC Davis called EV Explorer.

We thought it would be fun to compare our last two gas cars to our two BMW i3's. We slid the milage 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 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 it's 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 $5700 a year driving our two BMW i3's fueled by sunshine. That annual savings is nearly the annual cost of one of the BMW i'3s.
