If this thing goes, it's 2% of China's electrical capacity gone, and that doesn't even touch on the millions of deaths, disruption to food supplies and supply chains, subsequent disease and starvation, etc. A humanitarian disaster of that magnitude hasn't been seen in our lifetimes.

I feel like how many toothpaste brands are available in a store is not pertinent to the actual issue at hand, as to whether increased electricity demand on a per capita basis constitutes 'manufactured demand' or not.

There are two aspects here that could be in question. One is whether things like AC, refrigeration, water heating and laundry machines count as essentials or not. The other is the extent to which these uses as opposed to fancy widescreen TVs or Alexas or what have you is driving increases in per capita load, possibly allowing for taking into account manufacturing or data centers as opposed to pure direct residential load.

Was there a recorded drop in Co2 output or electricity use over the past few months of the pandemic?

Travel and other expenditures must have been way down. As well as restaurants and manufacturing sites being shut down.

A big part of the "free real estate" thought when it comes to rooftop solar is that the land and buildings have already been developed and structurally set-up to support electrification, including the last mile to the place the power is being generated. That's not negligible.

Bulldozing hills in the desert to build solar farms doesn't just require you to grade the hills and drive foundation piles for the mounting systems, it also means building roads and high voltage distribution lines and switching stations and industrial inverters to carry that power to where it's needed, potentially hundreds of miles away.

Yes it’s called building infrastructure.

And the counterpoint is that it's tough to transport that much material and workers into existing cities. The transport apparatus is already sized to bring in the stuff the city needs and for the workers and inhabitants to get around. In other words, there are also bottlenecks to simply putting solar panels on the top of every building. And then maintaining them and replacing them as they fail. Maybe you'll wind up building additional housing units in the city for all those workers.

But at some point it seems we have to admit that there is no getting around it. Either invest into the tech and commit to significant work or we end up with endless talk about what could be the perfect solution.

Solar panels are really pretty space-efficient for how long they last. Given that they last ~30 years, working on roughly 3% of the solar capacity in a city in any given year isn't a huge ask in terms of infrastructure-supporting-infrastructure.

An issue I was considering recently is that so many houses have ridiculous decorative rooflines and eaves and gables that absolutely destroy the ability to place an effective solar system on them. And almost every flat roof commercial building has preposterous distributions of equipment on the roof in random locations that prohibit simple rooftop solar there as well. Just changing permitting guidelines to make new construction solar-friendly would massively, massively decrease costs and increase performance.

Would legislation which mandates that all new built homes in solar efficient regions must have solar pre installed be at all possible in the current Us political climate?

That nuclear line looks pretty stable, even if you can see the point where the one reactor got shut down.

Natural gas being what hosed up the most is never going to be addressed in this state though!

Maybe I’m reading it wrong, but solar and wind looks to have had similar drops (proportionally) as natural gas.

China approved 100 GW of new coal plants last year. All of their total current and new nuclear is only 100 GW. They might get go 150 by like 2035, but that isn’t going to do poo poo for their current terawatt+ of coal generation.

In that same timeline how many old coal plants are they shutting down?

Seen here, there is a priority place on shutting down of older, smaller, and more polluting coal power plants. These are being replaced by fewer larger coal power plants. I've read that overall coal capacity is set to fall.
https://www.sciencedirect.com/science/article/pii/S2590332220306023

quote:

Plants decommissioning remains the priority

Although significant progress has been made in reducing Hg emissions via SUS, the coal power industry still faces great challenges given that a large number of pollutant-intensive small units remain in operation. At the early stage of the 13th FYP (2016–20), the total capacity of existing small units in China was 212.5 GW, equivalent to the total capacity of CFPPs in the United States. Since a large number of small units in China will come to the end of their service life before 2030, SUS will remain a focus of pollution mitigation strategies for the next decade. From the view of provincial regions, the extant small units are concentrated in several provincial regions, such as Shandong (29.45 GW), Inner Mongolia (12.57 GW), Henan (10.61 GW), Jiangsu (10.23 GW), and Shanxi (9.62 GW), which together make up approximately half of the national total. On one hand, small units, especially those with capacities under 300 MW, failed to meet the increasingly stringent environmental requirements even after ultra-low-emission retrofit. On the other hand, the costs of efficiency improvements and the installation of APCDs are beyond the affordability of small units. Incentivized by the increasingly stringent environmental requirements (e.g., Emission Standard of Air Pollutants for Thermal Power Plants27), China will commit to promoting an early retirement policy among small units with intensive pollution in the future.28 However, if all the small units are decommissioned radically in a short time, some regions may encounter large power gaps. For example, in Shandong Province (China's third largest provincial economy), small units with capacity less than 300 MW still provide over 35% of the province's total capacity. If all the small units are decommissioned immediately, Shandong will face a power shortfall of more than 100 million kWh.29,30 Thus, an appropriate timetable for the provincial CFPP shutdown campaign in China is recommended, especially in regions where small units still play an important role. Meanwhile, specific development plans for alternative energy are needed. For the provinces with abundant renewable energy resources, such as Inner Mongolia, Gansu, and Qinghai, their local renewable energy could be further explored as a substitution for coal power. For provinces such as Shandong and Jiangsu, where coal power dominates and the potential of renewable energy is comparatively smaller, replacing pollutant-intensive small units with large ones with higher Hg removal efficiency could be a feasible policy for Hg emission control.

Carrying around the weight of solar panels doesn’t make any sense (a theoretical maximum of ~1 KW/m^2 vs a 80KW motor on a Nissan Leaf); the extra weight costs you more energy to cart around than it generates, even in the Sonora. Their claim of 1000 miles of range would mean they’re carrying way more batteries than they need.

It is as fantasy driven as a gas Hummer; a different market but an appeal to image over function.

It's a glorified long distance competition EV. It has no safety to speak of and the interior looks like a college project. They had some YouTuber test drive it and you can hear it creaking and groaning anytime it tried to accelerat.

This stupid point is brought up every time, yes they are permitting new coal, but at the same time they are shutting down the same amount if not more, replacing older smaller and dirtier plants with larger cleaner ones.

Am I missing something here?

People are responding to a graph that shows power generation in China is mostly fossil fuels followed by a small portion of hydropower and nuclear and an even smaller portion of solar and wind as if it is an indication of progress?

Because this situation looks incredibly bleak. The graph may not be the best, but I don't think you can get a positive interpretation out of it without a severe dose of optimism.

The graph shows that after about 2010 coal basically stopped increasing in China. Yes it's still a large percentage, but almost all the newly added power have been alternative to fossil fuels. The total number of coal should also drop once they have sufficient nuclear and other sources to cover base load.

But the narrative that China is building more coal plants than ever is a convenient lie that allows other to point a finger at them and say see we don't need to do anything because China is ignoring their climate commitments.

We need two simple rules. Increasing CO2 is forbidden and your power plant needs to provide stable power at all times. The industry can then decide if they want to build renewables with large scale storage, nuclear, or coal plant with proven sequestration system.

So pretty much what China has been doing, why aren't other nations doing the same? Seems like a lot of talk but either nothing is being done or actually going backwards in the case of the Germans.
