Small tip to my northern neighbors. Swamp coolers. Essentially a fan blowing across a medium of water. Crazy low power consumption compared to AC. The only caveat is humidity. It works by essentially exchangeing water for thermal energy. So if its already humid it won't work. But if the humidity is below %40, you can cool a room by up to 6 or 7 C

TIL: Most of Canada is humid, had no clue. Thought countries near the arctics didn't have to worry about that.
