As of September 6, 2012, I have logged 5,185 gas-free miles in my ActiveE. Actually, 400 of those miles were driven by any number of strangers before I took delivery of the car. That leaves me with 4,785 gas free miles from mid May to now.
Had I driven those same miles in my GMC Yukon, which gets around 15 mpg when I'm driving it, I would have used 319 gallons of gas. At an average of $4.25 per gallon, that comes to a whopping $1,355.75 over three and a half months. Or $387 per month that I am not spending on gasoline.
If I subtract the $387 I am saving per month against the E's monthly lease payment of around $538 (with taxes), that leaves me with a net monthly car payment of about $150. Not bad for a BMW.
What does it cost me to charge my E at home you ask? Nothing because I have solar power. I am credited with .54 cents per kWh during the day for the solar power I produce, but I only use power at around .15 cents per kWh by charging the E between midnight and 6:00 a.m. So I can charge the E and have some power left over to offset my home utility usage.
It really does pay to be green.
