    I just hooked up one if those kill a watt meters to my pip charger. I called Long Island power yesterday and they told me that I lay about .18 a kilowatt all in. So I set the meter at .18. Charged he car an it cost me .83 to charge it. I get about 10 miles to a charge. Take .83 x 5 equals $4.00. X 5 because on gas I get about 50 mpg. I also pat about 4.00 gallon so I effect. The electric charge is costing the same as gas on Long Island.

    His numbers are wrong. Either his Kil-A-Watt isn't working correctly, or it's set up incorrectly. He said he pays 18 cents/kWh, and Kill-A-Watt reports a cost of 83 cents per charge.

    No way... that's 6.4 kWh to charge the car. The actual is less than half that.

    Just got the kill a watt yesterday. I will double check the setup. Maybe I did something wrong.

    And for LIPA (Long Island Power Authority) use 20 cents/kWh it's closer to what they actually charge.

    It did sound a little high to me, because even though I don't own a Pip, I estimated the cost per mile in the $.05 range.

    So the. It would would be about .60 a charge. So .60 for 10 miles. Vs about .76 cents per mile in fuel (based on a gas price of 3.81 gal). So plug in makes sense. Or cents :)

    Here is the way I figured it. Of course, YMMV

    3.1 kWh x $.19 = $.589 But, I used 12 mpc (miles per charge). So, the cost per mile is $.049.

    I have over 16K on my regular Prius HB and according to fuelly, I am averaging $.071 per mile. That's about a 45% difference from my PiP estimate.

    Anyone with PG&E in California should check out the E-9A whole house TOU rate to see if it works for them. It's a good deal if you do lots of charging overnight and can schedule other uses like laundry to off-peak hours overnight or during the morning on weekends. Of course, A/C use during the day should be limited and possibly run to cool the house in the morning before the 2pm peak rate kicks in. It works well for me but circumstances vary.

    That E-9A rate is being replaced in the next few weeks with a new non-tiered EV rate. At that point, E-9A will no longer be available for new accounts but will be retained up to another 2 years for existing rate users. The new EV rate is TOU and has an off-peak rate of 9-10 cents versus the existing E9-A off-peak rate of around 5 cents per kWh.

    The soon-to-be-defunct E-9A rate is (for summer, anyway) is
    [PRE]
    PEAK PART-PEAK OFF-PEAK
    Baseline Usage $0.30178 $0.09876 $0.03743
    101% - 130% of Baseline $0.31994 $0.11692 $0.05559
    131% - 200% of Baseline $0.50036 $0.29734 $0.15808
    Over 200% of Baseline $0.54036 $0.33734 $0.19808
    [/PRE]
    As mentioned, the new rate will be non-tiered. So for those us in the third or fourth tier (currently 15.8 and 19.8 cents, respectively), the new rate is actually cheaper.

    How do you think this conversation went during the transition from horse drawn carriages to gasoline powered vehicles? :)
     
  16. Possibly, your # is twice as much because you are using 208 Volts.

    At home I pay 8.1 cents per kWh. At work it costs 7.1 cents per kWh, but so far I'm not paying there.

    FYI - I have used the same combo condensing LG washer/dryer unit since 2005. It's a great appliance with several advantages and one lifestyle change. Advantages: no need for an exhaust line through a wall, so you can place it anywhere close to a water line and existing drain (like in a closet deep inside the house with a wall shared by a bathroom). It is significantly quieter as well than standard washers and dryers. Finally, you can "set & forget" a load once you put it in because you don't have to transfer clothes from the washer to the dryer - i.e. you can be gone to work, or sleeping, and it's dry when you return or wake up. The unit has a five-hour "rotate drum every 5 minutes" feature once the wash/dry cycles are done, to mitigate wrinkles. Lifestyle change: we had to re-learn how we time our wash loads, because thanks to the condensing drying method each combo load takes between 2.5 and 5 hours to complete. Not a problem, just a change in planning how you wash - again, perfect for middle of the night washing and drying while you sleep etc. I highly recommend it based on seven years of flawless service. If you have a small house or condo, it also saves 50% of the space (one machine vs. two).

    The interesting thing is.... IIRC there were actually full electric vehicles around before ICE vehicles.
