Neither the US cares about the climate amd doesn't care about the optics either.

This is capitalism in action: solar is cheaper than anything else per kwh. The obsession with fossil in the West is due to the fossil fuel lobbies, not because of the rational market forces. China doesn't have that.

Household solar installations are still too expensive to be a reasonable option for many consumers in the United States. The amount of solar generation is also very dependent on where you live. Not to mention, it is becoming increasingly difficult to become a homeowner with people achieving this milestone later than ever. If you rent, it’s not really an option at all.

I'm as big of a proponent on solar as anyone, but to avoid confusion, understand that those cheap solar figures come from using state subsidized Chinese panels on near worthless land in the cloudless remote southwest.

If you are trying to use American made panels near population centers in the Northeast or the Midwest, the economics become much more challenging.

California obtains almost 80% of their daily needs from solar, and is the world’s fourth largest economy. Almost the entire US could run off of solar and batteries based on current utility scale costs of both technologies (but will likely continue to use a mix of nuclear, renewables, batteries, transmission, demand response, and fossil gas for filling in the gaps as learning curves continue to deliver cheaper low carbon energy).

It's simply a matter of will (or in the case of the US, lack thereof).

US Fossil Fuel chain right now is not very vulnerable. Vast majority of oil/gas production is internal or from nearby states that foreign powers would have hard time cutting off and our relations are ok with, recent administration aside.

I don't think it's that simple.

China is a signatory to Kyoto and Paris.

They do care about reducing pollution, and have managed to do so quite significantly in many cities.

China also has quite a bit to lose: many large cities on the coasts, and worsening water shortage problems.

National security probably plays a large role, and I reckon they would prioritize economy over climate, but the evidence implies that they do also care.

The US farms 60 million acres for corn and soybean biofuels currently. Lots of suboptimal ag land available for more efficient energy production (besides rooftops, irrigation canals, parking lots, etc; California has 4k miles of irrigation canals they can cover with solar PV, and is actively working towards this goal). As _aavaa_ mentions, agrivoltaics are very favorably for solar PV and ag production synergies.

(average age of farmers is ~58 years old, and with the decline in labor for ag, now is an optimal time to lease and lock up this land for renewables for the next 25-30 years [at which point generators can be repowered or the land returned to its previous condition])

Fossil fuels aren't just bad for global climate, air pollution (which is mostly local) kills 7-8 million people per year.

There's an interesting study that arises from a natural experiment based on coal subsidies in China[0]. It found that life expectancy in otherwise similar locations is 3 years lower where the subsidy is paid, and thus more coal is burned.

The entire world gets the bulk of their energy from fossil. One country is leading the pack in defossiling their economy relatively rapidly, and that's China. Double emissions of the US translates to half-emissions on a per-capita basis. Much less if you include historical emissions. And China's emissions dropped in the previous period, the US increased.

The coal plants are known to be built to support economic growth for one (simple truth), and as baseload for renewable sources (you simply can't go renewable without this, at the moment). Coal plant utilisation rates have been dropping for two decades and are expected to keep dropping. [0]

I’m not sure it’s absolutely knowable. These are all just opinions. But I feel that China is far more likely to actually care about the climate than America is.

One of the benefits of being a pseudodemocratic centralized government is that you can kind of decide something is important without worrying how to get reelected in a few years. All it takes is a leadership that decides this is their vanity project to be remembered by, or perhaps to actually care about China in 100 years (the Americans obviously can’t think or see this far anymore). This is possibly helped by having a population with a culture of collectivism. For better or worse you don’t have to actually solve the “what’s in it for me?” question that seems to completely screw climate plans when the plan is, “it’ll suck for you but your grandkids will appreciate it.”

Oversimplification to single causes is sign of poor thinking.

Solar is also economically better for China.

Secondly, I would strongly guess China ramped up production thinking that there would be more overseas demand. It isn't just low demand from the US; for example my "green" New Zealand is also not buying utility scale solar (oversimplified reason from horse's mouth: it is due to our major electricity generators colluding - the actual blocking reasons are more capitalistically complex).

There are very few situations in the world where cause and effect are clear: facile explanations of cause and effect are usually wrong in important ways.

"Lying by omission" means things not said. Facts deliberately left out to mislead.

And you omitted the fact that majority of cumulative carbon emissions come from developed countries. Not to mention you're spreading your lies on an article that's literally about them reducing total emissions, the final refuge for people like you ("America still emits less, the climate doesn't care about pe-capita blah blah"). Seriously, re-evaluate your priors. Consider the possibility that maybe, just maybe, someone is doing something about the climate, and not even on purpose, while we just sit around.

Apparently they are because 80% of their energy growth doesn't come from those plants. I think they're part jobs programs, part backup plan.

This is all factually accurate. If you're a renter, see if your utility offers a community solar option. This enables you to get economic savings and exposure to solar without installing a system yourself. If you're a homeowner, in many cases, the return on investment (depending on installation cost) is under 10 years (after which your power is free for the life of the system, which will exceed 25 years). It should be compared to a bond return/investment (assuming cash purchase vs financing or a lease).

In 2025 the Chinese coal consumption has in absolute terms decreased while they have kept building.

New built renewables are able to both absorb all new demand and reduce coal usage.

Sure, it would be better to not build coal plants sitting idle and instead spend the money on renewables and storage.

Through selectively quoting facts you make it seem like China is expanding their coal usage which is incorrect.

Not in China. China has lots of coal but has to import gas, so they build coal peakers instead of gas peakers.

Wrong, it's simply true. Solar panels use land poorly, the MW per unit area is poor.

Agrovoltaics accounts for less than 0.5% of commercial solar installations in rural lands. Effectively no one is doing this, it's not cost effective. You can't fit tractors/combines between the panels.

52. bgnn ◴[] No.45112864{3}[source]
True. But as usual there is more to it. US is running on cheap fossil fuels to most part, though the renewables aren't negligible too. The fossil fuels are actually subsidized, and they are cheap because they are results of exploitation of cheap land. On top of that there are subsidies like tax breaks on the drilling costs etc.. To be fair this is also the case for hydroelectric etc.

So, similar dynamic. If the oil fields, coal mines etc would be sitting on prime land, you wouldn't have it this cheap. If there weren't subsidies, they wouldn't have been this cheap. It's very hard to compare different energy sources because of this. But solar being cheap isn't only a Chiblnese phenomenon. India, Spain etc all prove this. It's cheap when you have a lot of empty land and sunshine.

So, if you have plentiful natural gas, then, yes, certainly, that's what you'll do; it's far, far easier and cheaper. China does not have plentiful natural gas, and is indeed building coal peaker plants.

Scroll through the last 72 hours here and you can kind of see it in action: https://app.electricitymaps.com/map/zone/CN/72h/hourly

Now, clearly, there's a long way to go, and China does still have a lot of baseload coal. But it's not building much if any _new_ baseload coal.

Think that's weird? France has load-following _nuclear_ plants (it more or less has to, given how much of its grid is nuclear).
