how much sulphur hexafluoride greenhouse gas Indonesia

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (Sulfr hexafluoride) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on insulating gas in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, insulating gas is 22,800 times more effective at trapping infrared radiatiSee more on epa.govAir and climate - Air and GHG emissions - OECD Datadata.oecd.org/air/air-and-ghg-emissions.htmGreenhouse gases refer to the sum of seven gases that have direct effects on climate change : carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (Sulfr hexafluoride) and nitrogen trifluoride (NF3).Get price
