Oil and Energy

[aphexcoil]

Does anyone know how much energy is contained in a kilogram of gasoline? How about ethanol, Butane, etc? Does anyone know know if there is a general formula given the type of carbon chain?

Ok, I found it.

Energy density of gasoline:
12.7 kWh/kg or 8.76 kWh/liter

29,889 BTU/l of gasoline

22,217 BTU/l of ethanol - however, ethanol burns more efficiently and is considered (when comparing to gasoline) to have a "replacement" coefficient of 26,575 BTU/l - there's also a 3,720 BTU/l of energy represented by co-product displacement

35,109 BTU/l of soy-based biodiesel
