Air Conditioning Causes Around 3% of Greenhouse Gas Emissions. How Will This Change in the Future? We need to accept that demand for cooling will increase, work on making it affordable for those who need it most, and build efficient solutions that ensure electricity grids worldwide can cope

Little coincides better with PV than air conditioning.
We need to replace all methane heating with heat pumps.
To put that into perspective, aviation accounts for [2% of global emissions](https://ourworldindata.org/ghg-emissions-by-sector). So 3% is a pretty huge number.
Air conditioning is a classic case of [the Jevons paradox](https://en.wikipedia.org/wiki/Jevons_paradox); units are [50% more efficient](https://www.energy.gov/articles/history-air-conditioning) than they were in 1990, but their use has gone up by 300%.
It’s not just energy consumption. It’s leakage if the coolants, which are thousands of times worse than co2.
Werw building a startup to address this issue. Happy to chat more
