Authoritarian Asian countries being authoritarian as usual. Wouldn't mind putting up panels if I could sell and use the power. But fuck governments telling property "owners" what they can or can't do.

A mandate for renewable energy is authoritarian now? What? This is a great initiative.

The sensibility of a policy and the power dynamics of it’s application are orthogonal.

The solar covered parking lots near me are great because they also serve as cover for your car when it’s hot and sunny. It’s not the most cost effective way to install solar, though. A tall structure designed to put the panels high up in the air and leave a lot of space for cars is a lot more expensive than normal rooftop solar or even field setups. This is basically a way to force some of the cost of clean energy as…

A better version for shade and city beautification is to force trees around/within the parking lot.

Trees can cause a lot of trouble if you don't give them enough space to grow. "Enough space" depends on the kind of the tree, but it's typically similar to a parking space. You can mandate trees, but then you'll get less parking.

This is a great idea, whether full of cars or empty, a lot of heat is absorbed by the parking lots. Just covering them means the concrete below cannot heat up.

I was going to say, there must be some research on how much/little this impacts the urban heat island effect.

It seems inefficient to put solar panels over parking areas as it requires significant amount of structure which costs a lot more than shade it creates is worth. Especially compared to how much less structure is needed on more remote solar farms. Maybe I'm just using American mindset where there is lots of open land that is good for solar generation? Perhaps not true in Korea?

I'm an American, and it seems like a great use of land to me. This sort of a policy is particularly sensible in areas where it's hot, and there are extensive parking lots next to places that are mostly active during the day. Instead of just having a heat island, you generate power to run AC in the associated buildings, and you also get shade for the parked cars.

I recently was at the Vegas airport, and what struck me was the parking lot.

It was the same parking lot I saw many years ago. But this time, instead of feeling sorry for the owners of the cars that were obviously getting cooked up, that whole are was shaded in bajillion solar panels.

It seemed like such an obvious win-win for everyone, I expect it to catch on fairly quickly.

South Korea has a population density of 507/km² [1] For comparison, the San Francisco Bay Area has a population density of 430/km² [2] I doubt they have vast tracts of undeveloped land. And while solar panels can replace agricultural land or wooded areas, doing so isn't always a big political win.

South Korea has tons of undeveloped land. Just look at an aerial imagery map. It’s just that it’s quite mountainous and heavily forested. (Not that I think we should tear down the forests for this - surface parking lots are already an inefficient use of space)

Earlier quoted context omitted.

Tree shade means bird poop danger.

Imagine considering some bird poop staining the paint dangerous instead of the air pollution that's slowly killing you.

I wonder if this will make it preferable to build parking structures rather than parking lots.

That is definitely not going to be easier or cheaper.
