Renewable energy technologies (and solar especially) are about as important as oil was in the 20th century. America literally went to war multiple times internationally to get access to that sweet juice. It makes absolutely no sense that America would not want to have access to excessive amounts of cheap energy today, and that’s why it is straightforward that America will do a 180° turn-around and start calling the Chinese their “best friend” for providing them with ample amounts of solar energy panels.
Your analysis assumes American decisions are made for American benefits, treating America like a monolith, or a single actor.
America has capitulated governance to a minority of ultra-wealthy psychopaths who have repeatedly proven they will fuck over anything and everything, including America as a whole, and any segment of its population. Trump is deperately trying to stop renewables and support oil and coal even though they are less economic and advantageous in the immediate here and now, let alone benefit America in the future. Its scorched earth psychopathy.
