when was natural gas first used for energy
Natural gas Natural gas was discovered accidentally in ancient China, as it resulted from the drilling for brines. The natural gas was used to boil brine to make salt.[7] Natural gas was first used by the Chinese in about 500 BC (possibly even 1000 BC[8]). They discovered a way to transport gas seeping from the ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt,[9] in the Ziliujing District of Sichuan.[10] The world's first industrial extraction of natural gas started at Fredonia, New York, United States, in 1825.[11] By 2009, 66 000 km³ (or 8%) had been used out of the total 850 000 km³ of estimated remaining recoverable reserves of natural gas.[12] Based on an estimated 2015 world consumption rate of about 3400 km³ of gas per year, the total estimated remaining economically recoverable reserves of natural gas would last 250 years at current consumption rates. An annual increase in usage of 2–3% could result in currently recoverable reserves lasting significantly less, perhaps as few as 80 to 100 years.[12]
History of the petroleum industry The use of petroleum dates back to ancient China more than 2000 years ago. In I Ching, one of the earliest Chinese writings cites the use of oil in its raw state without refining was first discovered, extracted, and used in China in the first century BCE. In addition, the Chinese were the first to use petroleum as fuel as the early as the fourth century BCE.[2][3][4][5]
