Speculation.
I understand and share your concern with keeping foreign enemies from having too much knowledge about security-related matters, but our international slaver bosses have seen to it that the most elite and most impoverished human traffic is easy and maximized between friendly and enemy countries. That’s a gaping hole caused by so-called free trade (not free at all).
One answer would be to have communities build many independent power plants and for individuals to be more encouraged to build their own power plants without regulatory and fee obstacles. That would lend to a much more decentralized and secure energy infrastructure for our nation, just as open source heavy equipment manufacturing will.
