I think you're right, but it's amazing to me that in 2021 with all the technology we have at our disposal that we're still very much dependent on oil drilling, refining, and gasoline consumption.  Solar technology is definitely available; I just think it's unaffordable for most folks, at least for the initial outlay for solar panels and whatever else is needed to power an average home.  I would imagine that once the price comes down for those things (and people wise up to the fact that solar is cheaper and better for the environment), adoption will increase.

I also get the feeling that car manufacturers and big oil companies have hindered the adoption of alternative energy sources for a long time now, though backdoor lobbying.  If you asked me for evidence of that, I couldn't provide it, but those two industries alone have so much invested in keeping people dependent on oil that it's hard to believe that their pool of enormous resources hasn't gone into buying off politicians as well as influencing public opinion.

Viva la Tesla!
