$.21/kw seems high for home charging... im at $.12, before the extra savings that gets me closer to $.10

  Varies widely by state and other factors. I'm at around $0.18 for 1kWh when you look at the overall bill including generation, supply, and all other fees. (My car averages 3.3 miles / kWh, so ~$0.055 / mile assuming 100% charge efficiency... I'm using a 120V outlet so it's probably 75-80% charge efficiency, pushing the cost to ~$0.068 / mile.)

    Is using a 120V charger really only 80% charge efficiency? That would add another penny or two per mile to my cost.

  I was at $0.12 3 years ago, but rates have jumped (and there's two more years of planned rate increases coming up)

  $0.21 was from memory, so I pulled up my bill and it was actually low: Southern California Edison on the time-of-use plan, charging during "Super off peak." Note that nowhere on the bill do they show one number for how much you pay per kWh. These numbers will change next month as we go from "Winter" to "Summer" Delivery charges: $0.17664 CCA Cost responsibility surcharge: $0.02007 Nonbypassable charges: $0.00644 + $0.00591 Fixed recovery charge: $0.00619 Generation charge: $0.05958 Unless I typoed something again (oops 800k) that works out to $0.27 for the cheapest I can pay in winter. I compared last fall and this was by far the cheapest plan offered to me for overnight charging.

    Just got my first summer bill, it's about $0.02 more per kWh, so $0.29

  And yet half what they charge in some areas of California
