It is that simple. Solution would be a strictly local generation of electricity from renevables to avoid necessity for high voltage power lines.
Funny how you claim that, and yet in the real world, as posts on this thread show, there ARE effective substitutes, and there are plans to eliminate SF6 in spots, and hopefully as Kub points out, this trend will spread.
Just because a substitute isn't perfect or there are trade-offs does NOT mean substitutes can't be used.
I was not aware of rather recent Siemens work.
It also remains to be seen how those vacuum based switches are working in real life and what are consequences of their eventual failure.
It may well be a giant arc destroying entire substation, unless blown off with explosives.
High voltage solutions for 400 000V transmission lines are still not there and those for 115 000V are just being tried with no guarantee of success.
My major argument was that PV or a windmill (up to 2MW at least) does not need any SF6 to operate, contrary to Plant's claims. These are power transmission systems where it is needed.
As usual re all the doomer claims various problems can't be fixed, a little cost or inconvenience is just that -- not a valid implication of either short or long term doom.
Some problems may be fixed and some other problems cannot.
To have a doom it is enough to bump on one doom magnitude problem from category of "unfixable".
To avoid doom you have to be right *all the time*.
For doomer it is enough to be right *once*.
Mind you, resignation from high voltage national grid is actually a good fix of SF6 problem, particularly once renevable technology is reliable enough.
Who said that national grid has to be kept alive at any cost?
OTOH, the most blatant problem of continued significant population growth doesn't get addressed, which makes me pessimistic long term. I'm talking about given technical problems when viable alternatives are well documented (gasp) even when they're not perfect or cost free.
Nuclear war or global pandemic of airborne Ebola like nicety will fix it.
You may breathe easy.
