People have survived “deadly” wet bulb temperatures long before electric refrigeration. Air conditioning is a patch for colonial societies and those that emulate them that have stupidly built western European style (Cfb climate optimized) housing in tropical climates.

Universal solidarity doesn’t just mean solidarity with the poorest US citizens, it means solidarity with the billions of people who don’t have AC or a car. Giving US citizens who already have AC and a car free electricity will probably be less effective and less equitable than a more egalitarian degrowth-based distribution of resources.The OOP mentions electric cars, which are simply a luxury when public transit and utility vehicles (kei trucks, vans) exist. Air conditioning likewise can be a luxury when passive design exists. Cisterns, shade, plant respiration, air flow management, high roofs, large communal spaces that reduce outer surface area, etc.

People have a right to live a cool and comfortable life, but that does not mean the right to live in a nuclear family suburban home with paper-thin walls and not a tree in sight, basking in full sunlight, with AC on full blast, using your electric SUV to drive half an hour to the grocery store or school. A tropical longhouse shared with your community, a natural or artificial cave system, or living somewhere that isn’t trying to kill you (as badly) can serve that purpose just as well.

So instead of pushing for free electricity for American citizens, I would much rather push for degrowth of the American economy, with smarter designs that simply need less electricity.
