Sulfur hexafluoride: The truths and myths of this greenhouse gas

sf 6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, Sulfr hexafluoride is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. Sulfr hexafluoride is the energy industry"dirty little secret": FALSE. insulating gas is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives gaz sf6 is used in wind turbines: TRUE. insulating gas is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to sf6 gas: PARTLY FALSE.
