Any country as computerized as the US is a sitting duck for all kinds of serious, perhaps deadly, mischief. From Peter Pry at thehill.com:
“A long-term outage owing to EMP could disable most critical supply chains, leaving the U.S. population living in conditions similar to centuries past, prior to the advent of electric power. In the 1800s, the U.S. population was less than 60 million, and those people had many skills and assets necessary for survival without today’s infrastructure. An extended blackout today could result in the death of a large fraction of the American people through the effects of societal collapse, disease and starvation. While national planning and preparation for such events could help mitigate the damage, few such actions are currently under way or even being contemplated.” — Congressional EMP Commission (2017)
The people of Rangely, Colo., are not waiting for Washington to protect them from a Great American Blackout caused by a solar superstorm or cyber warfare or electromagnetic pulse (EMP) attack. Like several other Western municipalities, Rangely, a town of 2,300 in northwest Colorado, home to a community college, has rolled up its sleeves and, in the best traditions of Western pioneering spirit, independence and self-sufficiency, is building redundant microgrids so they can survive anything.
Texas state Sen. Bob Hall and his colleagues aren’t waiting for Washington to “provide for the common defense,” either. Hall’s bill to protect the Texas electric grid from all hazards — including EMP, cyber warfare and sabotage — recently passed the state Senate.
