Might we learn from the Texas electrical grid debacle? If we Californians are smug our temerity, (we) may be punished. The interpretations of what happened to the Energy Reliability Council of Texas (ERCOT) electrical grid are baffling. Texas Governor Abbot asserted the causality was the renewable energy facet of that grid. A frozen 4,500 megawatts (MW) of wind turbines were the problem when 30,000 MW of fossil fuel electrical generation plants went offline? Then, there is the gloating by some who state that the dilemma is not enough renewable energy. âReliably unreliableâ renewable wind power produced 42% of ERCOT's electricity on Feb. 8, and on Feb. 11, 8%. Not enough Texans can afford $7,500 for 5,000 watts of Tesla's Powerwall backup to residential solar.
