All this talk about energy independence and not a word on where are the solar cells, batteries and wind turbines made. If your grid is standing on components with short life time and which you can't manufacture at scale, you are not independent. You have just traded one dependence for another.
Sorry, what is the previous dependency?
If you're talking about longevity of solar or wind turbines, given that their lifespan is measured in tens of years, it does give you some ability to respond to some external group cutting your supply off. It's not remotely the same as oil/gas dependency.
Wind turbines and solar panels have similar lifespans to natural gas power plants which are also made somewhere else.
Steam turbines are made in the US, and they are the principal mechanical component in natural gas power generation.
