Note: An average price is provided for the selected fuel source per unit of measure.
Natural Gas note: If the price for natural gas is based on $ per 1,000 cubic feet, divide that price by 10. For example, if the cost for natural gas is $16.50 per 1,000 cubic feet, then divide by 10 and enter $1.65 as the price per therm.
