Most of the ethanol consumed in the U.S. is in the form of low blends with gasoline up to 10%. Shown a fuel pump in Maryland selling mandatory E10. Beginning in late 2008 and early 2009, the industry came under financial stress due to that year's economic crisis. Motorists drove less and gasoline prices dropped sharply, while bank financing shrank.

The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Price per million BTU of oil and natural gas in the US, 1998-2015 Natural gas prices spiked to $23.86 on February 17, 2021 because of the Texas power crisis. [14] In February 2003 there was a similar spike in natural gas prices because of shortages. [15]
A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.
American drivers had it rough back in 1981. The average price of gasoline spiked to $1.353 a gallon that year — up from $1.221 in 1980 and more than double the price just three years earlier.
The amount of natural gas produced both from associated and non-associated sources can be controlled to some extent by the producers. The drilling rates and gas prices form a feedback loop. When supply is low relative to demand, prices rise; this gives a market signal to the producer to increase the number of rigs drilling for natural gas.
