As I repeatedly remind people, you don’t build an electric power grid to handle routine weather conditions, you build them to survive rare but extreme weather events. Texas, which became enamored with wind power — wind accounted for between 22% of the state’s electricity in the first half of 2019 — has learned this lesson the hard way. In the midst of a bitter cold snap expected to last several days, ice storms knocked out nearly half the state’s wind-power generating supply. The spot price of electricity has surged to $9,000 per megawatt hour, compared to $100 per megawatt hour during periods of high summer demand. The Electric Reliability Council of Texas called on consumers and businesses to reduce electricity use as much as possible Feb. 14, through Feb. 16. Just imagine how bad the situation would be if Texas derived 100% of its electricity from renewable energy.
Meanwhile, the question Virginians need to be asking in anticipation of the commonwealth deriving much of its electricity from offshore wind power within a few years is this: What’s the freezing temperature for salt water?
Answer: 28.4° Fahrenheit. Continue reading
