What would happen to electrical infrastructure on Earth if the sun passes through a period of massive solar flaring as occurred in 1859 or 1921?
On Earth, power lines, data connections and even oil and gas pipelines are potentially vulnerable.Here's the scary part: if government leaders follow through on their threat to install a "smart grid" in order to facilitate "green energy", the power grid will become up to 100 times more vulnerable to solar flares, EMP attacks, and computer hacker attacks. Think about that at your next Sierra Club outing.
An early warning of the risk came in 1859, when the biggest CME ever observed unleashed red, purple and green auroras even in tropical latitudes.
The new-fangled technology of the telegraph went crazy. Geomagnetically-induced currents in the wires shocked telegraph operators and even set the telegraph paper on fire.
In 1989, a far smaller flare knocked out power from Canada's Hydro Quebec generator, inflicting a nine-hour blackout for six million people.
...Recurrence of a 1921 event today would fry 350 major transformers, leaving more than 130 million people without power, it heard. A bigger storm could cost between a trillion and two trillion dollars in the first year, and full recovery could take between four and 10 years. _Breitbart
