PDRC can be contrasted with conventional compression-based cooling systems (e.g., air conditioners) that consume substantial amounts of energy, have a net heating effect (heating the outdoors more than cooling the indoors), require ready access to electric power and often employ coolants that deplete the ozone layer or have a strong greenhouse effect.

You can always plant more trees, paint all the buildings brighter colors, live underground, or move north?

Yikes.
Yeah by like 400W which is peanuts compared to what the sun is doing
A typical air conditioner consumes 1kW, and on top of that heats the outside by however much the inside is cooled.
Yeah but that heat is merely redistributed, it’s not like it’s adding to the total temperature
