The energy that is released from natural gas can be used to heat homes, power businesses and generate electricity. Barrels or gallons for liquid petroleum fuels (such as gasoline, diesel fuel, and jet fuel) and biofuels (ethanol and biodiesel), 1 barrel (b) of crude oil or petroleum products = 42 U.S. gallons, 1 barrel of (U.S.) dry measure = 3.29122 bushels or 4.2104 cubic feet, 1 barrel (42 gallons) of crude oil produced in the United States =, 1 gallon of finished motor gasoline (containing about 10% fuel ethanol by volume) =, 1 gallon of diesel fuel or heating oil (with sulfur content less than 15 parts per million) =, 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) =, 1 short ton (2,000 pounds) of coal (consumed by the electric power sector) =, 1.039 million Btu per thousand cubic feet. Each week, the actual heating value of gas in each BTU area is measured by sampling the gas and analyzing it with a gas chromatograph (except in collection areas, as explained below). Net BTUs take into account the fact that some of the heat from burning fuel is used to vaporize water in the fuel itself (for example, in gasoline). HHV = LHV + [water vapor] x 2,257 kJ/kg The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it..
