Starting a new thread using Hill's idea.
Let us use this thread to document everyone's energy economy - and see how it compares with the EPA figures.
The main efficiency (or as they say, Energy Economy) figure from EPA is 34 KWh/100 miles or 2.9 miles/kwh. This kwh should be calculated at the wall - not carwings or what Leaf shows. This means, you should either have TED/kill-a-watt, separate meter or Blink to figure out the energy used by the car at the wall. You should also keep track of any charges done when not at home.
I suggest keeping track of and reporting the following figures. Copy the format below and replace with your actual numbers.
Where,
a = Total Miles (from Leaf odometer)
b = kWh used (from the wall)
c = Miles / kWh (a/b from above)
d = Leaf Miles / kWh (weighted average of what Leaf reports, if you reset the number every day)
e = CarWings Miles / kWh
f = $ spent on Electricity for the car
g = Cents / Mile (f/a from above)
Here is my example for March.

Code:
Month : MMM-2011
a. x,xxx Miles
b. xxx kWh (Wall - Blink/Seprate meter/TED etc)
c. x.x Miles/kWh (Wall)
d. x.x Miles/kWh (Leaf)
e. x.x Miles/kWh (CarWings)
f. $xx.x
g. x.x Cents/Mile
a = Total Miles (from Leaf odometer)
b = kWh used (from the wall)
c = Miles / kWh (a/b from above)
d = Leaf Miles / kWh (weighted average of what Leaf reports, if you reset the number every day)
e = CarWings Miles / kWh
f = $ spent on Electricity for the car
g = Cents / Mile (f/a from above)
Here is my example for March.
Code:
Month : March-2011
a. 565 Miles
b. 177 kWh (Wall - Blink)
c. 3.2 Miles/kWh (Wall)
d. 4.1 Miles/kWh (Leaf)
e. 4.9 Miles/kWh (CarWings)
f. $19.5
g. 3.4 Cents/Mile
