Fuel Source Alternatives
Comparison to Coal
|
The table below compares the cost of historical
fuel sources. Alternative energy sources are
only included indirectly under the assumption that alternative
energy sources such as wind and solar power are typically used via
the electricity that they are configured to produce. Note
that the price of electricity can vary widely.
How
to use this chart…
Check the price of Anthracite coal in
your area. Find that price in the Anthracite Coal column below.
In the row corresponding to that coal price, you will
find the prices of other heating fuels necessary to match the
BTU/h output to price ratio for coal. If coal costs $130 per ton, to get the same amount of
energy (BTU/h) for the same cost, heating oil would have to cost
$0.65 per gallon and propane would have to be $0.42 per gallon.

Heating Value by Unit Chart
The following is a listing of heating value per unit for common heating fuels. The column of equivalent units is based around the heating value of 1 ton of wood chips. For example, to get the same heating value (BTU's) as a ton of wood chips, you would need to burn 54.9 gallons of #2 fuel oil.
