By that token I could conclude human brains are nonfunctional by pointing to the geniuses who decided to isolate Texas to its own grid.
The reality, of course, is that countries like Canada, Denmark, and Sweden all use wind power as well. Maybe we should be importing the commie wind generators
Actually, Texas was the first state to tie their power generation together in a grid. Over the years there were discussions to tie the grid in Texas to the other two major grids, but statistically, it never improved the reliability of the Texas grid. There were enough power plants in the state of Texas and enough interconnection capacity to keep the state powered through any foreseeable combination of the demand for power and the loss of power production.
Power system availability shares the same problem with other infrastructure, how much do we plan for increasingly rare combinations of power production and demand. Do we now plan for sub-zero temperatures in Texas at a considerable cost for a once in 100-year occurrence? What do we do? Insulate homes better to lower the demand for power at an added price for homes of 5 to 10%? Do we bury more electrical distribution or transmission lines at the added cost of 40 to 600% paid through our power bills?
Power generation has a further burden because we are trying to impose a profit motive onto what probably should be a government infrastructure supply. Profits are a counter-intuitive process to power system availability. About 60% of your power bill now goes to the gross margin of the power company; depreciation, interest, taxes, etc., and ~23% profits, not to pay for the generation and distribution of electrical power. Is it worth it in a non-competitive industry? I would like to see that argument if you believe that it is.
