Global annual emissions are 8,100 tonnes, equivalent to the CO2 emissions of 100m cars. It has an atmospheric lifetime of over 1,000 years and its installed base is expected to grow by 75% by 2030. 80% of all SF6 is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so … [Read more...]
