Joe P is right, the push for “green” power isn’t what is causing electricity disruption in Texas. Among the main factors: 1. Texas chose not to interconnect its power grid with neighbouring states, so they can’t supply energy when Texas is under strain; 2. Seasonal shutdowns of coal and natural gas plants for maintenance, because normally winter is a LOW-demand time in Texas; 3. Shortages of natural gas at gas-fired plants, in part because gas demand for home heating is high, and supplies can’t keep up. So, don’t blame “green” power, blame inadequate Texas preparations for extreme weather.
