It's just not true.
North America & Europe (temperate/cold climates) Heating dominates. In the U.S., for example, space heating accounts for roughly 2–3× more total energy than cooling on an annual basis, especially in northern and central states. In Europe, cooling demand is tiny in comparison — many countries use almost no air conditioning outside southern regions.
Why heating dominates overall:
- Large parts of North America and Europe have long winters.
- Heating often uses high-energy fuels (natural gas, oil, electricity), so the energy content is higher even if cooling is more frequent in some places.
- Cooling is mostly electric and can be efficient with modern A/C systems, so it consumes less energy per degree of temperature change compared to heating.
