My uncle in Phoenix said his AC bill dropped $50 a month after planting a single shade tree.

He showed me the spot where he planted it, right outside his west-facing window. Has anyone else seen a big change from just one small project?

Remember reading about a guy who painted his flat roof white with that reflective coating. He said his upstairs rooms felt ten degrees cooler almost right away, and his AC didn't run nearly as much. Made me wonder about all the dark roofs in my own neighborhood just baking in the sun all day.

I read about a study in Los Angeles that modeled city-wide cool roof adoption. They found it could lower the surrounding air temperature by almost two degrees during a heatwave. That's the part we miss, it's not just about one house saving money. If enough neighbors did it, we'd all get a break from that trapped, heavy heat that sits over the streets at night.
