If a really BIG solar flare makes a direct hit on planet earth, the US power grid will go out. It will be a cascade-effect. The most vulnerable power plant will spark out, then the next plant down the line will go out, and so forth.
It is not a question of IF this will happen, but WHEN.
A high-powered bomb in our atmosphere will have the same effect.
Either way, a United States without electrical power is a United States in chaos. It will take YEARS to recover.
The COAST TO COAST AM radio show addressed the consequences August 21. Here is a summary from that show.
In the first half of Thursday’s show, advocate for protecting America’s power grid, Peter Pry, shared updates about preventing damage from EMP (electromagnetic pulse) attacks and solar flares. “This is the most important issue of our time, because EMP, even though it’s unfamiliar to most people is the greatest threat our civilization faces,” he remarked. Individual states have started to pass legislation because they’ve run out of patience with Washington, he said, but we may not be moving fast enough (NASA recently released a report that Earth narrowly missed a highly destructive solar flare in 2012, and North Korea continues to test missiles and projectiles ).
Bipartisan proposals, such as the Shield Act, which would harden the electric power grid against EMP, have been stalled by lobbying from the electric power industry, which doesn’t want to spend the money. Currently, the Chairman of the U.S. House of Representatives, Energy and Commerce Committee, Rep. Fred Upton has refused to bring the Shield Act out of committee and up for a vote. George suggested that people write Rep. Upton (contact info/Facebook) and let him know how they feel about this. Both Russia and China hardened their grids years ago, Pry noted.
