Texas has more wind power generation than any other state in the US by far. Texas is all aboard the wind train. It's a huge part of the economy. Texas wants wind to win. But that doesn't change reality.
In the last month, Texas has gotten close to electricity demand exceeding supply. A significant factor behind this is that Texas gets nearly 20% of its electricity from wind generation. On your average summer day, wind generates between 15 and 25 GW. However, during the recent heat wave, wind speeds dropped in west Texas (where the bulk of the wind farms are) and wind was only generating less than 2 GW during the hottest part of the day.
Similarly, Texas usually gets about 10 GW of power from solar. However, solar drops off to 0 GW very rapidly around 7 or 8 PM. However, in the summer in Texas, the temperature is still at its peak around 7 PM, so there is still significant demand while solar generation is dropping.
Wind and solar are unlike thermal generation in that we (humans) can choose to burn more oil and create thermal generation when needed. But with solar and wind, we cannot choose to suddenly create more wind or sun. We are at the whims of nature, and until we figure out better solutions for these problems (battery storage, maybe), wind and solar have their disadvantages compared to thermal. Pretending otherwise is not helpful.
