For those wondering what the causes are of Texas blackouts, @JesseJenkins is doing a really good real time analysis of generator capacity and operation. (Short story: we have a natural gas problem in TX). A few additional thoughts to add:
Confidential info from a market participant in ERCOT: As of ~10 AM Eastern time, the system has ~30 GW of capacity offline, ~26 GW of thermal -- mostly natural gas which cant get fuel deliveries which are being priorities for heating loads -- and ~4 GW of wind due to icing. https://t.co/Bfpn0WeRIq

1/OK, data mystery time.
This New York Times feature shows China with a Gini Index of less than 30, which would make it more equal than Canada, France, or the Netherlands. https://t.co/g3Sv6DZTDE
That's weird. Income inequality in China is legendary.
Let's check this number.
2/The New York Times cites the World Bank's recent report, "Fair Progress? Economic Mobility across Generations Around the World".
The report is available here:
3/The World Bank report has a graph in which it appears to show the same value for China's Gini - under 0.3.
The graph cites the World Development Indicators as its source for the income inequality data.
4/The World Development Indicators are available at the World Bank's website.
Here's the Gini index: https://t.co/MvylQzpX6A
It looks as if the latest estimate for China's Gini is 42.2.
That estimate is from 2012.
5/A Gini of 42.2 would put China in the same neighborhood as the U.S., whose Gini was estimated at 41 in 2013.
I can't find the <30 number anywhere. The only other estimate in the tables for China is from 2008, when it was estimated at 42.8.

Frontline first aid.
Nurses, doctors, medical students and ordinary citizens with first aid training have clamoured to join a small volunteer corps helping treat people involved in the Hong Kong protests

Pro-democracy activists kick off three days of rallies at Hong Kong airport.
Protesters hope to win international support from arriving passengers. The last demonstration at the airport on July 26 passed off peacefully without causing flight disruptions

It is simply not correct to point fingers at wind & solar energy as we try to understand the situation in TX. The system (almost) had a plan for weather (almost) like this. 1/x
It relied on very little wind energy - that was the plan. It relied on a lot of natural gas - that was the plan. It relied on all of its nuclear energy - that was the plan. 2/x
There was enough natural gas, coal and nuclear capacity installed to survive this event - it was NOT "forced out" by the wind energy expansion. It was there. 3/x
Wind, natural gas, coal and nuclear plants all failed to deliver on their expectations for long periods of time. The biggest gap was in natural gas! The generators were there, but they were not able to deliver. 4/x
It may be fair to ask why there is so much wind energy in ERCOT if we do NOT expect it to deliver during weather events like this, but that is an entirely different question - and one with a lot of great answers!! 5/x
Conservatives are using the Texas power chaos to argue against climate policy even as fossil-generated power outages dwarf the amount of renewables knocked offline during the historic deep freeze. President Biden and progressives have been slow to respond.https://t.co/UajKhptEAU
