Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.

Why SF₆ emissions from the renewable energy sector should not

Increasing Sulfr hexafluorideGlobal Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...

Why SF₆ emissions from the renewable energy sector should not

SF₆ is a very powerful greenhouse gas and its long lifetime will mean that it affects the climate for thousands of years. Its emissions should be regulated and reduced, and governments should encourage the development of alternative electrical insulators to SF₆. It’s important to continue monitoring this gas in the atmosphere to ensure that strategies to reduce emissions are working, but the contribution of SF₆ to climate warming is a very small fraction (0.04%) and decarbonisation

Why SF₆ emissions from the renewable energy sector should not

Feb 10, 2020 · Renewable energy installations require more switchgear in the electricity grid than fossil fuels, because it takes more solar panels and wind turbines to produce the same electrical output as a single coal power station. So as renewable power generation grows, emissions of SF₆ to the atmosphere should grow too.
