Neighborhoods with more trees and green space stay cooler, while those coated with layers of asphalt swelter. Lower-income neighborhoods tend to be hottest, a city report found, and they have the least tree canopy.

The same is true in cities across the country, where poor and minority neighborhoods disproportionately suffer the consequences of rising temperatures. Research shows the temperatures in a single city, from Portland, Oregon, to Baltimore, can vary by up to 20 degrees. For a resident in a leafy suburb, a steamy summer day may feel uncomfortable. But for their friend a few neighborhoods over, it’s more than uncomfortable — it’s dangerous.

      Pv is now around $30/m^2 wholesale and $60/m^2 retail.

      Not much more expensive than a sheet metal roof (far cheaper than a mature tree after all the water and tending), but a sheet metal roof doesn’t produce $100/yr worth of electricity.

      Tree good. If can’t afford tree, then pv obvious choice.

        You can buy the panels, inverter, racking and a battery which produces more than enough for anything smaller than a mansion for <$10k. Batteries are also not really necessary and can be added later.

        Why are you paying > $20k for someone to put in 60 screws and a piece of conduit?

          For one thing, that’s not what I’ve seen in terms of pricing overall. For another, believe it or not, not all of us are able to do things like install solar panels on a roof.
