More bad news from the environmental movement:
Where once large coal-fired power stations brought energy to millions, the drive to combat climate change means they are now being replaced by mixed sources of power including wind, solar and gas.
This has resulted in many more connections to the electricity grid, and a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.
Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.
Also: levels are being under-reported and it’s hard to get rid of.Published in
