You are thinking of natural gas fueled turbines, you can also burn hydrogen in gas turbines. If that hydrogen was produced domestically via electrolysis using clean sources there isn’t any strategic issues.
Also, from a strategic perspective burning domestic natural gas and burning natural gas from a different country are very different things. Europe becoming dependent on Russian natural gas was stupid, but America burning it’s domestic natural gas is mostly just an environmental issue.
You don’t want gas turbines anywhere near the grid. It is a terrible strategic choice besides the obvious ecological effect.
