yes but the main dependance on imports is for transportation fuels - electricity in the USA is produced almost entirely by coal (#1), nuclear (20%), and natural gas (largely from US and Canada).....
so the real “dependency” issue comes down to when/if we can move away from imported oil sources for transportation fuels..... which depends upon whether economic and technical issues can be resolved for electric or hydrogen cars, etc.
Definitely I think we should use FAR more nuclear power to generate electricity, but that doesn’t really get at the OPEC issues, it’s more to the question of whether we can/should use less coal (which we have in great abundance).
Of course a trillion dollar question is how much more transportation can/should/will be electrified in the next 5, 10, 20 years, etc. I really don’t know, but I do believe that the Democrats should not be controlling such decisions and economic processes.
