Household Air Conditioner Ownership by Country

Air conditioning is one of the most unevenly distributed technologies on Earth. Roughly 3.5 billion people live in regions where AC is a near-necessity for parts of the year and yet just 15% of them own one.

What drives air conditioner adoption?

Levels of income predict AC ownership far better than temperatures.

Countries with high levels of AC adoption include Japan and South Korea, the US and the Middle East, wealthy nations which often facing scoring heat. While poorer yet still hot nations like Indonesia, India and South Africa have low levels of adoption.

The region that doesn’t fit the mold is Europe, with continent-wide adoption sitting at just 20% of households. Cooler historical summers, dense older housing stock and a cultural resistance to AC have kept penetration low, but that’s starting to crack. France's evening electricity peak ran 25% above the seasonal average during the 2025 heat waves, a sign that low-AC Europe is becoming more exposed to heat, not less.

In other words, cooling-degree-days tells you where AC is needed, but GDP per capita and electricity access tells you where it actually gets installed.

Trends in air conditioner adoption: Global AC ownership is on track to roughly double by 2050, when about two-thirds of the world's households are projected to have a unit. China, India and Indonesia alone will account for half of all AC units on the planet by then.

Space cooling is now the fastest-growing source of energy demand in the buildings sector, rising nearly 4% annually through 2035 under current policy settings, and more than 80% of that growth is concentrated in emerging and developing economies.

Power demand from air conditioners is expected to triple by 2035, according to the International Energy Agency.

Heat pumps, the other side of the electrification story: Heat pumps do both heating and cooling, which makes their adoption pattern a useful counter-map to AC alone, and a good proxy for where electrification policy is actually working.

Sales in Europe were up 10% last year across major markets, driven by Germany, where first-half sales jumped 55%, in part due to subsidies. 2025 was also the first year that heat pumps outsold gas boilers in several European markets.
