[Greenbuilding] cost of electric versus natural gas and gasoline

[Kathy Cochran]

Enter in your local cost of fuel:    Multiply by:    Your cost per 1 Million
BTU's:  
   Electricity  at .086  per KWH  X  293  =  $25.20     
No. 2 Oil    per Gallon  X  9.61  =  $0.00     
Propane    per Gallon  X  13.32  =  $0.00     
Natural Gas  @ 1.02  per Therm  X  12.5  =  $12.75     
Pellets    per Ton  X  .089  =  $0.00     
Cord Wood    per Cord  X  .073  =  $0.00     
 
    
 
  Determine the amount of BTU's required to heat your home per month (this
can vary greatly depending on region, home insulation, heat use, etc.).
What's my climate zone?  
      Climate     Size of Home     BTUs Required per Month     
   Mild Winter Zone     1500 Sq. Ft.     1.5 Million     
   Mild Winter Zone     2500 Sq. Ft.     2.5 Million     
   Moderate Winter Zone     1500 Sq. Ft.     3 Million     
   Moderate Winter Zone     2500 Sq. Ft.     5 Million     
   Severe Winter Zone     1500 Sq. Ft.     5 Million     
   Severe Winter Zone     2500 Sq. Ft.     8 Million     
 
  Calculate the present cost of heating and the new cost of heating if you
are considering a different type of fuel by multiplying the cost per million
BTU's (C) for the type of fuel used, by the amount of BTU's required per
month (D). Make sure to check your present heating bill against the amount
of BTU's required per month to make sure the amount is correct.

  Subtract the new heating cost from your present heating cost to determine
savings.

I wrote a web page which will do the calculations for you.  Just enter 
your prices and efficiencies.
