HEAT PUMPS - THE WELL-TEMPERED FUTURE OF A/CS

Summary from the TLDR newsletter

Air-conditioners keep people comfortable and alive. Extreme heat waves are killing more and more people every year. The demand for more air-conditioners is exacerbating climate change due to increased demand for electricity and the leakage of refrigerants. Both winners of the 2021 Global Cooling Prize were heat pumps that reduce cooling's climate impact by up to 80 percent. Heat pumps address the problems of emissions while providing a source of emissions-free power. They're also comparatively cheaper to install than central air-conditioners.
