Heard of Sulphur Hexaflouride, SF7? Turns out the tonnes of it are leaking from wind turbines and it’s a significant greenhouse gas. This sounds like some kind of anti-renewables false article but seems pretty credible. What do folk make of it?
Shame that the BBC had to link it to wind turbines specifically, it’s used for all electrical Switch Gear.
What would have been nice in this article would have been a comparison of the total warming effect of SF7 vs “Other greenhouse gasses” .
Here’s a back-of-the-envelope calculation from the numbers that they actually do provide.
- SF gasses emissions for Europe equivalent to 6.73 Mt CO2e (from the article)
- Total European Greenhouse gas emissions (2016) 4441 Mt CO2e (from https://www.eea.europa.eu/data-and-maps/indicators/greenhouse-gas-emission-trends-6/assessment-2)
So, by my calculation, total SF emissions only account for 0.15 % of total greenhouse gas emissions for Europe.
Not a lot really.
That being said, it was great to hear that Scottish Power was building East Anglia One (just offshore from where I live) with SF-free switch gear.
The 0.15% of European Emissions certainly puts this is into perspective. Thanks!
