  Consumer Cost per Mile Economics:

 

     

  • Gasoline:    $3.00 gal / 30 MPG = $0.10 / mile    ($1.00 of gasoline cost is various taxes)

  • Hybrid:        $3.00 gal / 50 MPG = $0.06 / mile     

  • Electric:      $  .32 / kwh x 60 kwh battery pack / 320 miles = $0.06 / mile

  • Electric:      $  .16 / kwh x 60 kwh battery pack / 320 miles = $0.03 / mile

  • Hydrogen:   $3.00 gal / 25 miles = $0.12 / mile

  • Hydrogen:   $2.00 gal / 25 miles = $0.08 / mile

    

  

  Carbon / Mile Calculation

 

    

 

     

Lbs Carbon

 / Mile

 
  Gasoline:   .6    18 lbs carbon / gal / 30 mpg
  Hybrid:  .36    18 lbs / gal / 50 mpg
  Electric

 .276

.359

   60 kwh battery pack / 320 miles / .1875 miles per kwh

   1.03 lbs of coal produce 1 kwh electricity  (2.86 / 2 = 1.43)

   1.43 lbs x 1.03 x .1875

   (add inefficiency of 30%)

  Hydrogen:

1.4

1.8

   21 kwh makes 1 gal hydrogen which goes 25 miles   

   Coal makes 1.65 lbs Co2 per kwh

   21 kwh x 1.65 lbs Co2 = 34.65 lbs Co2 goes 25 miles

   (add inefficiency of 30%)

     

 

  Notes:

        2000 lbs (1 ton) coal makes 2.86 tons (5,720 lbs) CO2

        50 kwh to make 9 kg of hydrogen / 1 gal = 3.79 kg / 21 kwh makes 1 gal hydrogen

 

        Grams of CO2 per kwh by generations method:  (454 lbs per pound)

  Grams per Kwh Lbs per Kwh
Coal: 900 1.65 lbs
Nat gas: 465 1.02 lbs
Oil: 820

1.80 lbs

  • Natural Gas:  It takes 0.01003 Mcf (1,000 cubic feet) to make 1 kWh.  This includes power plant inefficiency.

  • Oil (residential fuel):  It takes 0.0016 barrels to make 1 kWh.  This includes the inefficiency of the conversion process.

  

  

  Vehicle Cost per Mile Calculation

 

     

  • Gasoline:    $28,000 / 100,000 miles = $0.28 / mile

  • Hybrid:        $32,000 / 100,000 miles = $0.32 / mile

  • Electric:      $36,000 / 100,000 miles = $0.36 / mile

  • Hydrogen:   $75,000 / 100,000 miles = $0.75 / per mile

 

  

  Tesla Model S

 

     

     Cost to Fill:

          90 Kwh  x  $0.16/kwh  =  $14.40

 

     Cost per Mile:

          $14.40  /  250 miles  =  $0.0576 per mile

 

      

     Tesla Fuel Efficiency rating  =  3 mile  /  Kwh

          $0.16  /  3  =  $0.051 per mile
