I think most people - even Floridians - know that our pretty small-population country swearing off all internal combustion transport will have zero impact on whether sea levels rise, because a ton of the coal burning and other massive pollution happens in countries that aren’t going to decarbonize (in fact, they think it’s fair game and morally right for them to use that cheap coal for 100 years since the Western cou…

America is not a small population country and is still per capital emitting more than China; while China is now on a downturn (admittedly from a very high absolute level of emissions)

IMO, that remains to be seen. China is still adding new coal capacity roughly equal to America's entire coal capacity, or about ~160+GW, just in 2025(74GW)/2026(90+GW expected) while retiring almost none.

It's not reliable if it's not grid tied. Your car might be fully charged. It also might not get any charge at all.

Going up thread a bit, I find "and have a fairly small connection to the grid." Though even without that, so what? The typical commute is not half a battery's worth of kilometres. And even for the exceptions, you're allowed to have a split between parking spaces labelled "this juice is completely free but slow at the best of times and depends on the weather" and others labelled "this juice costs ¥¥¥/kWh but is backed…

I would take the gamble somewhere there are 220+ days of sunshine per year, happy to pay occasionally and commute for free the rest of the time.

If anything all the panels can be connected together and charge the bosses cars up first and if there is any daylight left the charging can trickle down the org chart to the masses.

https://maps.app.goo.gl/Bw4PGRxDvQKSmDB3A Notice how there are trees planted on the grassy strips between the rows of parking? The solar panel supports take up a parking space at each end of the rows of bays with a lot of gaps in between. Google Streetview is from 2009 - nothing newer, weirdly - but if you nose about you'll see what an insanely cool building it is. You can walk around in those roof gardens.

That’s a well-designed lot and very cool green-roof building indeed! I would love to work there! But it serves a very different context and real-estate economics than the high-density examples linked by Troupo. A suburban insurance HQ in a mid-sized city doesn't face the same constraints as a retail hub in a capital. The target demographics and land pressure aren't comparable. In your example, they could have likely…

It's a very cool building indeed. I did all the radio equipment for the facilities and security guys about 15 (and maybe closer to 20) years ago which you can't quite see in the enclosure in the middle where the air handling stuff is. For testing I spent most of the day touring the building with an analyser checking signal strengths and drinking excellent coffee.

Almost makes me want to pack engineering and get into insurance sales.

They wouldn't have got planning permission for that.

Like this working-class (and fairly low-rent) part of Glasgow? https://maps.app.goo.gl/zKKz5HuywNnKhGY78

how's the tree situation though? 110F + lots of huge trees = a lot more tolerable. trees cool shit down big time.

It's a desert so trees can't survive without irrigation. Since water is scarce as well, there aren't enough trees to cover the vast low density area.

Just FYI there's a lot of ways to re-green a desert without actually being wasteful with water. There's some really impressive case studies out there. Shaping the land with berms and swales, building walls of trees to prevent water from being leached away by the wind, etc.

Capacity is less relevant than usage. It's not like you drive a combustion car by putting your foot to the floor on the accelerator and only modulate your speed with the clutch and breaks.

Chinese coal *consumption* seems to be trending down, not up, regardless of capacity: https://www.carbonbrief.org/analysis-chinas-co2-emissions-ha...

Does Korea also not allow Chinese cars?

They are allowed.

So we should expect Kia and Hyundai cars to get really good soon, if they have direct competition undercutting them like that.

It’s government only. It’s not red tape.

When government makes itself less efficient, it's still red tape.

But, isn't the albedo of a solar panel farm still way dark? It means the radiation is still being captured rather than reflected back up.

Even if it was just 0 albedo no generation, irradiation on whatever's parked beneath would be cut in half plus rest of (re-)radiation converted into far-ir. This is not unuseful. Just don't mandate this kind of thing in places where parking lots have to be cleaned up with bulldozers in winter.

If there are solar panels over the parking lot, then the parking lot doesn't have to be plowed. You can design the panels at appropriate slopes to direct the snow off the lot.

Sure, but China isn't building new coal plants, just for decorative value, but because renewables aren't stable.

Sure, we've seen this rodeo before, circa 2015 -- when it dipped a few points, then it continued on its march toward coal supremacy since.
