“You are being misled about renewable energy technology”

I've had so many arguments with people that think replacing a continual supply of gasoline with solar panels and batteries means that we are just as dependent on the source of solar panels as we are on the source of gasoline.
It's hard for people to visualize the massive shift here. It's the difference between needing to eat every single day, to merely needing to buy a 5-year supply and never having to worry about eating again until 5 years from now.
Except that it's 30+ years for solar panels, 20+ years for batteries.
The amount of independence and security that renewables-based energy infrastructure provides is hard to imagine for most people. The US's two big inflationary events in the past 50 years have been due to global fossil fuel supply shocks. And the second one that happened in the 2020s was when the US was a net exporter of energy! We still had exposure to inflation shocks because we had a global market for our energy sources.
Renewables change all that. Even if we bought all of our solar panels and batteries from China today, we'd have far better energy security, and have decades to build up the industry to replace them if we wanted to switch to autarky. (And autarky is a terrible idea, but that's a different discussion...)
That entire talk didn't once mention the phrase "energy density" which is the real reason we rely so heavily on hydrocarbons.
Additionally this talk makes the usual mistake of conflating "electricity" with "energy". While the US does have fairly high percentage of energy in the form of electricity it's still only around 33% of the US energy needs.
And still we see that "green energy" only supplements not replaces our other energy needs. We've seen tremendous EV adoption and yet US oil consumption is on an upward trend and nearing pre-pandemic highs [0].
It's wild that there are multiple, very serious global conflicts heating up over control of oil and people still believe we're just a few more years away from a purely green energy world with no evidence to suggest that's a remotely reasonable belief.
One nice thing about what’s happening is that politics are losing to reality. I’m not even sure how this became a left vs right issue in the first place (isn’t the right meant to be pro free market!?) but it doesn’t matter at this point anyway.
Eg. Texas is doing really well in renewable rollouts (see the amount of battery capacity they are putting in - https://www.houstonpublicmedia.org/articles/news/energy-envi...
It’s certainly not because of Texan politics either. It’s just cold hard reality. Renewables won’t be stopped at this point. Even the executive orders to halt wind farms don’t make a dent in what’s happening. We may end up a few years later than other nations but at least it’s unstoppable.
