Natural gas would be the source of 11 billion tons a year, with coal and oil now 8.4 and 17.2 billion respectively because demand is increasing 1.9% a year. To reduce its greenhouse emissions, the government of the Netherlands is subsidizing a transition away from natural gas for all homes in the country by 2050. In Amsterdam, no new residential gas accounts are allowed as of July 1, 2018, and all homes in the city are expected to be converted by 2040. Natural gas produces far lower amounts of sulfur dioxide and nitrous oxides than other fossil fuels. The pollutants due to
Carbon dioxide and microbial fermentation. In 1772, English chemist Joseph Priestley published a paper entitled "Impregnating Water with Fixed Air" in which he described a process of dripping sulfuric acid (or "oil of vitriol" as Priestley knew it) on chalk in order to produce carbon dioxide, and forcing the gas to dissolve by agitating a bowl of water in contact with the gas. Carbon dioxide was first liquefied (at elevated pressures) in 1823 by Humphry Davy and Michael Faraday. The earliest description of solid carbon dioxide was given by Adrien-Jean-Pierre Thilorier, who in 1835 opened a pressurized container of liquid carbon dioxide,
