Of course, but I would encourage anyone that's thinking about getting an electric car to figure out what they're paying for electricity and run the numbers to understand what the cost impact is.

To add another anecdata point, I live in the San Jose area and I just checked my latest PG&E bill; It's kind of complicated because there's a weird tier system, but I paid a weighted average of $0.2095/kWh last month. However, if I were to get an electric car, the additional electricity it would use would come from the top tier, which is $0.2409/kWh. Then again, gas is ~$2.80/gallon, so electric would still be cheaper, but not by much.

If you're a heavy user (probably with an EV) you can sign up for a Time of Use rate plan, which will give you access to lower rates for off-peak charging (and higher peak rates).

Wouldn't you often charge at night, when electricity is cheaper?
