Renewables are a thing for the upper-class. I am refering to plain old heating in winter, which is being switched over from russian gas to american lng. Great achievement!
At the time it made sense, we believed the US to be an ally, like in the past. Obviously not true anymore so yeah, a mistake that needs to be corrected.
And no, renewables aren't for the upper class, the sun is free for everyone with panels, and panels can be bought relatively cheap today.
I'm sure it depends on the country, but in my country (Spain) you can literally go and buy solar panels in the local hardware store and install them without permits, even for renters given you don't destroy anything. And besides that, most owners (as a renter) are OK with you installing solar panels.
Never owned a place, had solar panels installed in the last three places I lived in, the first two were apartments, currently renting a house. None of the owners had problems with us installing solar panels.
Ahh, thats why the EU is moving to LNG, now I get it!
