Liquefied petroleum gas Commercially available LPG is currently derived mainly from fossil fuels. Burning LPG releases carbon dioxide, a greenhouse gas. The reaction also produces some carbon monoxide. LPG does, however, release less per unit of energy than does coal or oil. It emits 81% of the per kWh produced by oil, 70% of that of coal, and less than 50% of that emitted by coal-generated electricity distributed via the grid. Being a mix of propane and butane, LPG emits less carbon per joule than butane but more carbon per joule than propane. LPG burns more cleanly than higher molecular weight hydrocarbons because
Polar meteorology used to measure conditions in polar areas. The atmospheric portion of the hydrological cycle in polar regions plays an important role in that: Carbon dioxide (C02) is of particular interest in polar meteorology because it affects the melting of sea ice. Human activity releases carbon dioxide into the atmosphere from burning oil, coal and natural gas. A dozen pounds of Arctic sea ice disappears for every pound of carbon dioxide released. This highlights the heating power of carbon dioxide, which pumps 100,000 times more energy into our climate than was given off when the oil, coal or natural gas was
