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.
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.
