> Doesn't this mean that solar/wind are insanely lucrative?

I used to work in wind energy in the Netherlands, it is only profitable there due to government subsidies. It was/is an enormously complicated system to understand on the whole. I was on the environmental impact side (visualizations) during the permitting process. It's high-risk & enormously expensive during the permitting process (i.e. getting permission to build the wind farm), and beyond that I understand it's a bidding process and again, super complicated on the energy trading side once you're operating. My experience was that the wind farm operators seemed to be doing well financially, but insanely lucrative? I'm not sure about that vs. non-renewables. Everyone I worked with (including myself) believed in green energy as a part of a larger mission to make the world a slightly better place. EU directives on renewables is what pushed the mission forward; the dutch on the whole (surprisingly), do not love wind turbines in their back yard.
