I have noticed this as well. My conclusion is that they value power more than they value money. Sustainable energy is necessarily not a one-size-fits-all solution, but adapted to the local needs & opportunities of each community. It's necessarily more complex and less well suited to economies of scale; it doesn't favor a handful of gigantic multinationals, and probably would look more like hundreds of large regional corporations.

I think they're probably waiting for some kind of silver bullet that lets us transition to a sustainable source of very similar chemicals, derived from biomass or directly from the air, without fundamentally changing society or changing how our power structures function, and that they think they're gunnuh do it in just the nick of time. Sort of a greater fool theory of climate brinksmanship, passing on each solution in the hope you'll find the perfect one before time runs out, but you're in a research lab where the clocks have no hands.

I fear that it may be worse, and that they may think they can actually just push through ecosystem collapse with technological solutions, and just never transition off of fossil fuels.
