Comparing Cost and Emissions for Fuels and Furnaces
Fuel Comparison Calculator ...




This is our own calculator to compare the cost and CO2 emissions for various types of heating systems and fuels.
Includes geothermal heat pumps, and some biofuels.

The Calculator...

Fuel Cost Calculator



This is a nice fuel calculator for comparing fuel costs for various fuels and heat plants.

A good feature of this one is that it includes duct losses for various kinds of duct systems -- these are sometimes large and often overlooked.
Fuel Cost Comparison Calculator
From ...


This is a nice fuel cost comparison calculator.

Give you a comparison of the cost of heating with 8 different fuels. 
Very nice.

Heat content in BTU for common fuels
Fuel Cost Comparison Chart

Explanation for chart:

Handy chart that gives equivalent fuel prices for a wide variety of common and uncommon fuels, including biomass fuels.

For example, electricity at 10 cents per KWH is equivalent to burning barley at $7.49 a bushel. 
Accounts for efficiency of the burning.
