Voltdriver -

I didn't do the more ambitious 3D plot thing, but I did create a spreadsheet :

The "5 year savings" is in comparison to the EPA ICE @ 23 MPG car. For example :

Code:

  (5 year cost of EPA ICE @ 23 MPG) 
- (5 year cost of my 1999 Saturn SW2) 
=  5 year savings

$12,391.30 - $6,627.91 = $5763.40 savings

In order to calculate the electric cost for one year I ignore the stated value for MPGe. I derive the electric cost from other values :

Code:

(X Mile driven / 1 Year) * ( Y Dollars / kWh) * ( Z kWh / Mile) = 
(Mile * Dollars * kWh) / (Year * kWh * Mile) = 
Dollars * ( Mile * kWh) / Year * (kWh * Mile) = 
Dollars / Year = Electric Cost
