Through this paper, we explained the use of alternative insulating gases as they are increasingly used due to the impact of greenhouse gases and are a solution that scientists apply to minimize their release. They are used in various industries such as power, chemical, electrical, and their use is encouraged by various environmental associations and the government, all for the purpose of preserving the environment and our planet. Due to their affordability and the fact that they are extracted from natural resources, they are one of the best solutions in the modern world. The most common and used gas is sulfur hexafluoride (SF6). However, because of the harmfulness it creates to the ozone layer, scientists are looking for alternative solutions with better performance and less harmfulness. Substitutes used for SF6 are perfluoromethane, perfluoroethane, perfluoropropane, perfluorocyclobutane, trifluorodomethane, perfluoropentane and fluoronitrile. All research is being conducted to protect our planet.
