I was talking with someone from Greece recently who was experiencing a heat wave and they dont have AC. I am from the south eastern US where we are basically required to have AC for de-humidification as much as cooling - we would be overrun with mold and mildew without AC in the summer. Our heat indexes regularly reach 105F during the summer and sometimes much higher. I joked the other day that if our aquifers ever ran out of water we could probably get most of what we need with just a better dehumidifier.

Edit to add: just in case, you should never use water out of a dehumidifier for anything but grey water use cases unless you sanitize and purify it - it can make you very sick!
