Nah can't really blame the oil and gas industry for that. CBI messed up with those nuclear plants and with them going broke, the likes of Bechtel picked up the pieces and really milked it. This kinda put people off building new ones, and right now, there isn't even that much gas plants being built. Most of the new stuff is wind and solar.US oil/Gas industry suck up all the skills/ investments and they can sell it to Europe/Asia as LNG at price multiples. so who want to work in Nuclear plants. for some reason so much investment in energy industry has yet to reduce manufacturing trade deficit.
Also, the LNG cycle takes a while, from FID to export first gas usually take around 4 years, and another year after that to get up to name plate capacity. Right now I count only Cove Point, Cameron and freeport LNG being operation, with Calc pass coming online soon. Those are only 20mtpa...
