Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for sf6 gas, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used sf6 gasin circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect sf6 gas emissions from electric power systems, such as the type and age of the insulating gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of Sulfr hexafluoride, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf6 gascan impact the climate. The electric power industry uses roughly 80 percent of all sf 6 produced worldwide. Ideally, none of this gas would b...
