The concept of decarbonization has dominated media coverage in recent years. We are slowly forgetting that this is part of a wider project that limits the emission of all greenhouse gases. Although CO2 emissions are actually dominant, this gas has a GWP (Global Warming Potential) = 1. In the article attached below, the authors refer to the scope of application of artificially produced SF6 insulation gas. It is an excellent insulating medium, which is biologically neutral in a stable state and has unique insulating properties. However, when an arc occurs, its decomposition products are extremely toxic. In addition, a very important issue is the topic raised by the author of the publication, which I will supplement with a simplified estimate: for each turbine in the ring system, there are on average three distribution bays with SF6 insulated. Each distribution bay contains approximately 0.2 kg of SF6 gas. So what is the CO2 equivalent in the system of 100 wind turbines?
 Well, it is 100 x 3 x 0.2 kg x 22,800 (GWP SF6) = 1,368,000 kg CO2.

Does all of that SF6 get emitted with every turbine? Or is controlling that part of the growing recycling programs for turbines?

Matt, 

Gas is not emitted by the distribution devices containing it. It is closed in sealed tanks and is controlled. The problem exists elsewhere: we produce artificial gas (not found in nature) with the highest possible GWP, although we can use mixtures of atmospheric gases (excluding CO2), the use of which gives similar effects to the use of SF6. There is simply no logic in it.
