So you understand - Wind and Solar failed almost completely. Demand exploded and rolling blackouts began to keep from crashing the whole system. THEY INCLUDED GAS POWER PLANTS in the rolling blackouts! This shut down the fuel flow and allowed the operations to freeze over. When a steam plant is running and everything is operational, it protects against freezing over.

When they say Natural Gas failed - it mostly failed because they wanted it to fail or they fucked up and let it fail. It was NOT as simple as failure to winterize.
