Sulfur hexafluoride: The truths and myths of this greenhouse gas

sf6 gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf6 gas is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. gaz sf6 is the energy industry"dirty little secret": FALSE. Sulfr hexafluoride 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 Sulfr hexafluoride is used in wind turbines: TRUE. sf 6 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 sf 6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf 6 at low-to-medium voltage levels in the future.
