Chapter 6, Problem 6.152QP

It has been estimated that 3 trillion standard cubic feet of methane is released into the atmosphere every year. Capturing that methane would provide a source of energy, and it would also remove a potent greenhouse gas from the atmosphere (methane is 25 times more effective at trapping heat than an equal number of molecules of carbon dioxide). Standard cubic feet is measured at 60°F and 1 atm. Determine the amount of energy that could be obtained by combustion of the methane that escapes each year.
