Accountants and economists commonly consider the cost of a barrel of oil or a ton of coal or a therm of natural gas to be the taking cost and the replacement cost is neglected. If the replacement cost of oil is used to establish the cost of gasoline at the pump, cars would be much more fuel-efficient. If we valued the replacement cost of energy, natural gas would not have been vented for decades from oil fields.

Fertilizer production increased from 30.0 million tonnes in 1979/80 to 45.2 million tonnes in 1988/89 and decreased rapidly thereafter to reach 27.7 million tonnes in 1992/93. FVoduction of all three nutrients, namely, nitrogen, phosphate, and potash, followed a similar trend. However, potash production decreased by a lower amount than nitrogen production partly because increased costs of energy (natural gas) had a smaller impact on potash production than on nitrogen production in Eurasia.

Calculating and tracking natural gas by volume can be useful, but natural gas can also be measured as a source of energy. Similar to other forms of energy, natural gas can be computed and presented in British thermal units (Btu). One Btu is the quantity of heat required to raise the temperature of 1 pound of water by 1°F at normal pressure (Spellman, 2009). There are about 1000 Btu in 1 cubic foot of natural gas delivered to the consumer (NaturalGas.org, 2008). Natural gas distribution companies typically measure the gas delivered to a residence in therms for billing purposes. A therm is equal to 100,000 Btu (approximately 100 cubic feet) of natural gas. The therm is equal to about 105.5 megajoules, 25,200 kilocalories, or 29.3 kilowatt-hours.

Calculations show that such plants would have an overall efficiency for the direct conversion of chemical energy (natural gas) to electrical energy [referred to the lower heating value (LHV)] of 62% in the near term, 67% in the medium term, and possibly as much as 74.6% in the long term, when the gas turbines will have been further improved. Disregarding the turbine, the efficiency of the fuel cells alone would be 50% in the near term and 57% in the medium term.

An investigation by the CSB determined that the 2010 explosion at the Kleen Energy natural gas electric generation plant, which was under construction in Middletown, Connecticut, was caused by a series of natural gas blows. Six workers were killed and at least 50 others were injured in the February 7 blast.
