People Living in the Hottest Places on the Planet Are the Least Likely To Have Air Conditioners (qz.com)

Zoe Schlanger, writing for Quartz: In 2016, roughly 10% of the planet's energy use went towards air conditioning. Figures vary wildly from country to country, though, and some of the hottest regions on Earth use the least A/C -- for now. A new report from the International Energy Agency says that's about to change. By 2050, the intergovernmental agency predicts, global energy use from A/Cs will triple, reaching a level equivalent to China's total electricity demand today. The African continent is home to some of the hottest places on Earth, but fewer than 5% of people in most African nations own an air conditioner, and energy used for cooling comes to just 35 kWh per person living in the continent, according to the IEA. In India, where large parts of the country are hot all year round, people use an average of 70 kWh for cooling. Compared to nations where having an A/C is the norm, that's almost nothing at all.

      Leaving the genius aside, it's a good opportunity to devise ways to cool ambients at lower costs with (let me just jot down some ideas for the moment):
      - landscaping (e.g. with fast-growing trees where possible);
      - advanced building natural cooling (I remember reading an article about houses in Morocco decades ago, it was based on storing cold air at night);
      - ways to convert thermal energy to electricity (closed evaporative cycles might be a way, I dunno);

      Building houses in most places is a business. In most places buildings are built to sell. The process is to build the building as cheap as possible and sell it for as much as possible. Building codes are set to force builders to build structures that won't fall down and that will last for at least a few decades (That's right decades. Note that NM cable, NEC required for electrically wiring can have a service life as little as 25 years. So yes buildings built in the 1980's could have wiring that is beyond it's service life. Even Romex, which is used in commercial construction can have a service live no longer than 50 years.)

      As in almost everything in the U.S. standards, while set by non-governmental organizations, are subject to regulatory capture. The groups that set them are heavily lobbied and in many cases administratively controlled by industry.

      There is also anesthetics. In many places weird buildings which don't conform to local design standards are prohibited. For example stores in Williamsburg Va are required to match local colonial architecture, at least in their facades, so no obvious solar arrays or modern wind power units. My HOA prohibits roof mounted solar arrays.

    (Judging by the summary) the authors of the report are projecting that added air conditioning in currently underserved areas will use energy-hungry heat pumps, like developed world city and suburbs currently do. This ignores recent (and any yet-to-come) technology breakthroughs.

    One is M-cycle cooling systems like Coolerado's. In locations where a swamp cooler would work, and many where it would fail due to moderately-too-high humidity, an M-cycle cooler will deliver cool air using about twice the power needed to blow it around and a little water (less than the amount saved by some power plant not generating the added electricity to power a heat pump, so you're AHEAD on water use, too). The air delivered does not have added humidity (just the higher relative humidity from cooling it, which WON'T drop it below the dew point and get mold going indoors), nor does it have added bacteria (though the half exhausted outdoors still may).

    The guts of the Coolerado version is a "mass-heat exchanger" - a stack of plastic sheets that gets water (with a trace of soap) injected on one port, outside air blown in another, cooled air coming out a third, wet air out a fourth, and an unevaporated fraction of the water with the minerals and such out a fifth. Cheap (or it can be if the patent holders chose). Already being used in, among other places, medical facilities in India.

    Another is the "infrared window" approach. Think "solar panel" that dumps about 90 watts per square meter of heat energy into the sky 24/7, (slightly better at night than noon). Cheap version of a plastic film with a silvered backside and 10-ish micron glass beads embedded in it. Only reason you need any power at all is to control the transfer of heat from the room to the panels (say, by circulating a heat-transfer fluid and blowing air through a radiator), so you don't get more cooling at night (when you probably don't want any) than at noon or afternoon (when you want a lot).

    Not only can these, and potentially other approaches, provide air conditioning for the developing world at a fraction of the energy cost (and perhaps the equipment cost) of a classic heat-pump system, but they can also reduce the energy cost of cooling in the developed world.
