I thought I made it blatantly clear that I see the culprit not in green energy but that garbage was purchased and constructed that was blown out on weather conditions that did not even beat 4 standard deviations. Quality natural gas powered plants can easily withstand much more extreme conditions than the one witnessed. And setting up wind turbines in Texas is almost as clever as setting up nuclear reactors on Japan's tectonic fault lines.
By your numbers, 25% of the grid is on wind, of which half are affected, so no, they did not all fail miserably. So Texas's grid is down 12% capacity. Where's the other 88% of good old dyno primary? Why are public regulatory agencies lobbying for inflated pricing for the energy companies?
