if honestly people think AC is bad for the environment people could switch to water based cooling systems. these are known as "coolers" in India and are used widely during summers as they are cheap and use really low amount of electricity and have zero effect on environment. it just costs like 30$ when compared to 300$ AC systems and have many advantages both economical and environmental. not sure why it hasn't picked up in developed nations?
