China is building the world's most advanced UHV grid right now.
UHV lines are good for carrying power over long distances. The high voltage level reduces line loss. But they are very expensive to build.
China's UHVDC Network now:

In the rest of the world, UHV lines have generally been used sparingly. Submarine power cables (e.g. connecting UK to mainland Europe) and some huge hydropower projects in Quebec are some notable exceptions.
China is building UHV lines on a scale never seen before.

So why is China different? Geography plays a huge role. China's load centers are in the coastal East and South, while the best wind, solar, and hydro resources are in the North, Northwest, and Southwest. Power (esp. RE) is being generated far from where it's needed most.

In the past, poor regional interconnectivity has been a big contributor to low offtake levels of renewable energy. Of course a glut of coal power also played a role. Curtailment has improved in recent yrs tho. I discussed regional grids before:

First, Chinese doesn't have a national grid, at least not in the way that small countries do. There are 6 regional grids (N, NE, NW, E, C, S). State Grid runs 5 of them and Southern Grid runs 1.

UHV lines provide a inter-region backbone to transport power hundreds or thousands of km across the country. The UHVDC lines are used for the longest distances, while UHVAC lines are used for shorter distances, often within the same regional grid.

2) I don't know what I'm going to do about it. That's a bridge too far. If I didn't have the thread reader app unroll above, I'd be checking my memory of my work. Thank goodness at least that's there!

Twitter disappeared 18 of my tweets. And they're not random.
3) At the same time, look what I find in my feed. Two announcements composed in identical format. I'll point out what's wrong with these "clarifications" below. This is from
Newsmax just aired this note to "clarify" its coverage of Smartmatic and Dominion. pic.twitter.com/I5XZ7CQpAk

4) And this from
Fox News hosts caught in a web of lies. Maria Bartiromo, Jeanine Pirro, Lou Dobbs all forced by the network to air exact same video of an expert debunking all the conspiracy theories they\u2019ve been peddling. Expect it to run on Hannity, Tucker, and Laura too. pic.twitter.com/lJrMO2m7l4

5) Isn't it interesting that both clarifications follow the exact same series of questions and answers? Obviously this is from the legal department, as if it were information to be shared. It is not. It is very, very carefully NOT information. Focus on that.
Some lay the blame for this on @boicy with the whole microservices thing.
(Admittedly, @nicolefv, @jezhumble and @realgenekim didn’t help when they statistically proved that he might have been onto something with all that de-coupling and team-alignment…)
However I don’t blame him at all.
I think he saved us; bringing us back to the path of value-delivery and independent services, but now with added independent teams.
But one thing is clear. Microservices need more architecture, not less (as do other forms of #Accelerate-style software organisation).
(See https://t.co/B2hWmXhIqe if you need convincing)
I mean, all those pesky slices we need to carve up our monoliths (or were they big balls of mud?) That’s a significant amount of work right there…

1. The gender analysis was "only meant to be exploratory” and used techniques that “cannot be claimed to establish causality” but causal inferences were made anyway.
Causal claims were justified by pointing out that other people do it too. "While this technique does not establish the existence of a causal effect, it is commonly used to infer causality from observational data."
