The professor at UT is a blow hard. He loves wind and will say nothing against it.
Even in the days when Texas relied on gas for electricity it was seldom that gas production fell enough to cause problems.
Wells these days are at lower pressure, they are older and depleted, that means less tendency to freeze from hydrate formation. Delivery rate may be a problem.
In the main, this is an exceptional condition spread over a wide area and probably one nobody wants to really pay the price to combat even if they could. Of course the sheeple will be whipped into a frenzy by propagandists like this UT professor and demand satisfaction or political heads and vast sums of money will be squandered with sound and fury signifying NOTHING.
