Note added Oct. 19, 2008: Ahhhh - the good old days. Back when corn was $1.85 a bushel? - well, this is one for the history books.
Below is a chart that compares the heating value of corn versus other heating fuels. Compare and follow the steps below to find your savings.

To find your savings: Example:
|
Step
|
1. Find current fuel source |
|
Liquid Propane |
| |
2. Determine amount used last year |
|
950 gallons |
| |
3. Multiply units used by BTU value per unit |
|
950 X 91,000 btu = 86,450,000 |
| |
4. Divide total by 450,000 BTU per bushel |
|
86,450,000 ÷ 450,000 = 192.1 |
| |
5. Multiply bushels by price of corn in your area |
|
192.1 x $1.53 = $293.91 |
| |
6. Subtract this amount from your last years bill
This is the savings you would have had last year
|
|
$798 - $293.91 = $504.09 |
| |
7. Estimate this years cost: Current cost x usage |
|
$1.45 x 950 gallons = $1377.50 |
| |
8. Subtract answer to #5 from #7 |
|
$1377.5 - $293.91 = $1083.59 |
| |
9. Estimated Savings for this year |
|
$1083.59
