Where trees are growing — and who has access to their shade — affects health and well-being, especially in one of the hottest states in the country.

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.

      It would cost about $30,000 for us to do solar cells and battery. That’s more than my car cost.

        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.

            Wild concept: It’s possible to offer a fair price to someone who can. You don’t need to pay $20k for one day’s labour (although you probably do need to pay about $1k for an hour for a licensed electrician to inspect and do the final hookup if you want to AC feed for winter and cloudy days). You do not need to pay $1/W or wait years for grid tie if you have a battery and size for self consumption.

            Given how thoroughly ripped off you are and how dismissive you are of the price people in civilised countries consider normal, I’ll assume you’re in the US. Signature solar sell panels for 31c/W hybrid off-grid inverters for $2k and batteries for $280/kWh. You can probably do better if you look around and don’t just listen to the door to door MLM scammers.

              Again, the prices you are giving me are not the prices I have been seeing.

              And I wasn’t dismissive of anything. I was talking about my personal experience. Which you are dismissing.

              And even if you’re right, I can’t afford $10,000 either.

                You’re just spreading propaganda.

                If you don’t personally want a thing then just shut up rather than polluting a discussion about a completely different use case.
