I read, from Obama who acted on the risk for the USA, that grids will be affected, probably badly so.
Has occurred on a smaller scale already:
I don’t think we will know the full extent until it happens to us here in SA … as most solar inverters are connected to the grid, AND it is a new “thing”.
You don’t need much to damage an inverter.
Adding to that. The actual challenge is IF transformers do get damaged, worse if they need to be replaced, is because of 1) where they are manufactured and 2) to get them from there to where they need to be replaced. It can take months, years even.
This is as of the 12th of July, 2023 …
… if we one day see auroras in SA, it would be awesome … for various reasons I suspect.
But, as my wife will say: So what can we do about it? … then she continues on with life.
Something new that I wondered about … so I Googled it. First, they said Nope, not, now there is a new thinking using 20 years of data …
Solar weather and its effect on Earth is a fact. But for humans today, it is a new study, the effect on us today in cities, solar systems, to say the least.
