A LNG terminal would help. Lots of bad infrastructure decisions have left us extremely exposed to those external shocks you mentioned.
Being dependent on gas is equal to being exposed to global shocks, unless you can cover your domestic needs purely with domestic gas extraction.
"My energy prices are high" because you are getting outbid. You can't stop getting outbid by building more transport infrastructure. That terminal will go unused.
Again, our poor decision making around national infrastructure is on our governments. They left have left us completely exposed to international markets.
As usual with the Greens, perfection was the enemy of the good.
This is a weird way to justify using LNG brought in through Britain.
