Energy Tax Prevention Act this bill would have amended several core components of the Clean Air Act (CAA). Title III of the CAA would have been amended to have the term “greenhouse gas” include: water vapor, carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and any other substance subject to, or proposed to be subject to, regulation, action, or consideration under this Act to address climate change. The Act said that the Administrator of the EPA may take no action involving the consideration of greenhouse gases as pollutants or contributing factors to climate change. It also said that “[nothing] shall cause a greenhouse
Sulfur hexafluoride circuit breaker Sulfur hexafluoride circuit breaker Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF circuit breakers are widely used in electrical grids at transmission voltages up to 800 kV, as generator circuit breakers, and in distribution systems
