I wonder how successful fire departments would be at putting out fires during severe solar weather. While it’s safe to say severe solar weather would require shutting down the power grid and would take offline most cellphone service and even radio communications, it’s not clear if it would it be strong enough nterfere with diesel engines or the largely gravity fed water systems.

It really depends on how strong the EMF is from the solar weather, how successful power companies are at grounding out power lines and even how dry the grass is under the certain to be arcing power lines. Peppers aren’t wrong to be very concerned with severe solar weather. It really would be very devastating in modern society.
