I wore a N95 mask whenever I went out. And would throw it away when I got back and Use a fresh one the next time. I basically followed CDC guidelines to a T. Still got covid.. Sick for 10 days but never required hospital care.
I read that while wind turbines only make up 25 or 30 % of the TX grid, of the grid sectors that lost power,40% were powered by wind turbines. But yes, lack of winteraztion played a huge role. I read that Ercot didn't do inspections of plants and turbines for winterazation due to the pandemic.
