Some estimates propose that dedicating 1–2% of the Earth's surface area to PDRC would stabilize surface temperatures. Regional variations provide different cooling potentials with desert and temperate climates benefiting more than tropical climates, attributed to the effects of humidity and cloud cover. PDRCs can be included in adaptive systems, switching from cooling to heating to mitigate any potential "overcooling" effects. PDRC applications for indoor space cooling is growing with an estimated "market size of ~$27 billion in 2025."
