Build covers with solar panels on their roofs. Provide shade and generate money in the long run. Most brick-and-mortar shoppers would be more attracted to covered parking, too.
It blows my mind that an article about shade deserts doesn't mention covering with solar collection systems. We all should expect anything intended to take sunlight should be a photovoltaic surface.
An increase in the number of solar cells in an area can be useful, but shade cover from trees would have a greater cooling effect on most areas. Trees both shade and provide transpiration cooling. The water evaporating from leaves cools the surrounding air as the water goes from a liquid to gas phase.
And just like solar panels, trees harvest a part of the energy in sunlight, giving additional cooling to just a shade. And trees are cheaper to set up, even if they may not provide a return on electricity.
Ideally you would have trees on the ground and solar panels on the roofs, to further increase cooling.
I really hope Biden pushes something next term that allows promotes solar like the current ev push.
Even better, ban HoAs from banning solar. Fuck that noise.
Trees should be the first priority, with solar cell shade a distant second. Trees only need water and minor maintenance, are far cooler to be under than a simple shade barrier, provide a lot of benefits like wind breaking and homes for nature to live in that are better for people than artificial structures.
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.
Now you're really being dismissive. Ironic.
It's always correct to dismiss concern trolls.
So it's bad for me to be dismissive but good for you to be dismissive. Fascinating double standard.
And I still don't have the money to spend whether it's $10,000 or $20,000. You clearly do. Enjoy your privilege of not being the over half of the people in the U.S. living paycheck-to-paycheck.
Yup. Definite concern troll behavior.
Pretending the worst prices in the most expensive place in the world for solar are normal. Then pulling the hostage shield politics card in a thread about public spending. Now crying victim.
Completely standard conservative reactionary behavior.
What are you even talking about now? They weren't the worst prices. The worst prices were like $50,000. It's almost like you don't know what I saw, isn't it? But you're clearly the Flying Squid expert here.
And again, enjoy your privilege. Must be nice to be rich.
Not a bad idea per se but it’s a very expensive solution. We probably won’t be able build enough panels for all of the shade we’ll need for future heat.
Trees are usually the best and easiest solution in most areas, but many municipalities including Tampa don’t take them very seriously. They need space for roots if they’re to provide adequate shade in urban areas.
This whole article is about residential areas, not commercial / retail ones.
How do you manage that in neighborhood with preexisting homes?
My wording was hasty. I only envision that new structures should be expected to come with solar tiles or panels. Like, you spent half a mil on a new house, do an extra 10-20k to have a useful roof instead of a ridiculous summer passive heater.
And yes, you're right, trees should be #1, and the main point of the article was really the disappearance of green spaces and coverage. This brief spot is what was on my mind in my take on it:
So I guess I had an "old man yells at clouds" moment.
Panels can be added.
To what? Homes? Sure, but who is paying for it? Otherwise what do you suggest, erecting covered parking spots over the tops of people's yards or driveways?
You can get subsidies to add on. And after they're installed, they save on energy costs, eventually paying for themselves.
Also, yes to driveways.
Carports have been a thing since they were called something else when used by horse and buggy.
