They can just shut down the pumps pushing the natural gas.
Or....someone hacks, for “ransom”, the system controlling the flow of gas, natural or otherwise, like they did with Colonial gas a couple of years back and damn near shut everything down in the SE.
And, of course, the Colonial folks had no backup, stated that they couldn’t run the pipeline manually because those that could were either dead or retired, had no legitimate cyber security protocols or safeguards, but they were diligently working on things to get it right.
Don’t forget that traitor neoCON “Republican” Ray LaHood, who served as demon Obama’s Transportation Secretary, first floated the idea of taxing people per mile driven and putting GPS trackers in cars. His son is now the Representative from the district he used to represent, because that’s how American-style elections roll.
This has been in the works a long time. It’s amazing to me how the one-world, satanic globalists (neoCONs, communists, leftists, and never-trumpers united together) play the long game. They don’t mind spending a century or decades achieving their objectives.
