4 million without power—Texas could have invested in at least 3 things for its frozen wind turbines:

📌water resistant coating on blades

📌more de-icing drones

📌upgrades in heating packages

➡️If they can work atop snow-covered Alps. They can work in Texas.🧵 #PolarVortex
2) Yes there is a lot of reports on the wind turbine issue. Texas could have invested in more upgrades, but it didn’t. dallasnews.com/business/energ…
3) I’ve personally witnessed entire wind turbine farms operate normally in middle of snow storms atop several mountains in the Austrian 🇦🇹 Alps before. They build it on top of snow capped mountains. And they use it to power ski lifts 🚡 during winter!
en.wikipedia.org/wiki/Wind_powe…
4) Good thread by @kurteichenwald on Texas crisis.
5) see the Austria wind turbines on the left side of this ski chair lift?

Notice how bitterly frozen ski lift 🚠 tower is without any deicing?

That’s the difference of cold weather protection.

Turbines can run ice free atop mountains in the Alps!

No excuse Texas @ERCOT_ISO.
6) that said, the main failure was its oil and gas production. Texas is producing 21 gigawatts below what is needed... wind is very minor. Most from other reasons. Texas is in a huge cluster
7) Oh hey, wind turbines in the Arctic. Maybe cold weather isn’t to blame. Maybe it was just Texas govt and @ERCOT_ISO incompetence. tugliq.com/en/realisation…
8) Two of these 3 megawatt wind turbines in the Canadian Arctic can together displace 4.2 million liters of diesel fuel each year. Let that sink in!!!
9) Texas overall had a thermal energy failure. Wind can’t be the main blame. Gas production and frozen pipes of oil and gas main issue.

10) US power grid... maybe Texas shouldn’t go it alone anymore. Collective sharing of energy... wow, what a concept!
11) For any Texans who need help with food, shelter, or mental health problems, please dial 2-1-1 or visit 211texas.org for help. ❤️
12) They don’t call it the Lonestar State for nothing... but Texas probably shouldn’t have gone it alone. #texaspoweroutage
13) finally some humor...

There are a TON of fake N95 and KN95 masks on the internet. You need to learn how to spot. See if reviews seem authentic or not. See if weird listing characters. Buy from manufacturer or from ⁦@projectn95⁩ that verifies all sources. #COVID19 #MaskUp nytimes.com/2021/02/17/tec…
2) Either double mask (at least 1 surgical mask or better), or switch to premium mask. There is just a lot of fakes to beware of.
3) There are fewer fake surgical masks. But double masking need optimally for surgical masks + another mask.

Did you know that twitter lets any crazy person share any batshit crazy thing?

This is BS. #MaskUp #doublemask #COVID19 Image
2) Please double mask if others around you don’t wear a mask. And maybe consider switching to a premium mask.
3) Consider a premium mask. Please. #B117 too contagious to take risks.

GOOD news—if you have certain Neanderthal DNA 🧬 & get #COVID19. People with certain Neanderthal genes on chromosome 12 have lower rates of ICU. This region encodes proteins that activate enzymes that are important during infections with RNA viruses.
pnas.org/content/118/9/… Image
2) That said, another Neanderthal gene is bad. “Recently, it was shown that a haplotype in a region on chromosome 3 is associated with becoming critically ill upon infection with #SARSCoV2 and was contributed to modern humans by Neanderthals”.
3) For this new finding, “a haplotype on chromosome 12, which is associated with a ∼22% reduction in relative risk of becoming severely ill with #COVID19, is inherited from Neandertals. This haplotype is present at substantial frequencies in all regions of 🌎 outside Africa.”

Texas still in crisis mode. And @ERCOT_ISO is still “load shedding” — a euphemism for cutting power via rollout blackouts. The problem is still systemic across Texas. Keep up to date on this site.

3) Here is what really went wrong.

What sent Texas reeling is not an engineering problem, nor frozen wind turbines. It is a structure that offers no incentives to prepare for winter. In the name of deregulation and free markets— electric grid that puts cheap prices over reliable service. 🧵

2) It’s a “Wild West market design based only on short-run prices,” said a portfolio manager, Matt Breidert. The temporary train wreck has seen the wholesale price of electricity in Houston go from $22 a megawatt-hour to about $9,000, while 4 mil Texans have been without power.
3) “One utility company, Griddy, which sells power at wholesale rates to retail customers without locking in a price in advance, told its patrons Tuesday to find another provider before they get socked with tremendous bills.” washingtonpost.com/business/2021/…

TEXAS LEADERS FAILED—power outages raise fears that herds could run short of food and water. Some farmers are being forced to dump tankers of milk on fields because it can’t be processed, & livestock maybe euthanized if no water or food. #texaspoweroutage wsj.com/articles/texas… Image
2) “No feed, no water, and no heat doesn’t make for a good situation,” said Texas agriculture commissioner. Some areas had gone without power for >30 hours straight—while fielding calls from cattlemen losing calves to the cold & poultry farmers struggling with frozen water pipes.
3) Sanderson Farms Inc., one of the biggest U.S. chicken companies, estimated that as many as 200 of its approximately 1,900 Texas chicken houses were without power, & dozens have ruptured or frozen water pipes. Mills are struggling to make animal feed without access to power
