1/7 Wind power cannot be blamed for electricity outages in Texas. Bad legislation, ownership models and worn out old electricity distribution grids can. Trust me - I come from a country with 50% wind power combined with well run grids and much colder weather (Denmark).
2/7 Certainly the extreme cold right now is very unusual and also makes it ok with an outage for a few hours. But days is more a systematic failure in my opinion. Also note that this phenomenon is connected to climate change!
3/7 Technically better more efficient buildings would have helped here in such a winter, but also with high cooling demands in the summer.
It's not really new that it gets cold in Texas. Last time was 2011 with 3 million effected for days. Now it's worse with 4 mill.
