It all can be summarized by looking at the numbers for elec generation on the date in question  Feb 15 2021, vs generation for that same date, one year earlier. 

Here's a link examining those numbers   Click Here  

When you look for the discussion of "numbers" you'll find quotes like this:  "There are literally no numbers in Krugman’s article (except for numerals referring to dates), which is a signal that he’s pulling a fast one on his readers. . ."

"Yet as we’ll see, the actual numbers tell a much different story from what most Americans probably “learned” from the media discussion." 

Here's some numbers from their charts -- I'm seeing power from natural gas rose from  398,000 Mwh the earlier year,  to 759,000 Mwh for 2021 the year of the freeze, an impressive rise of 361,000 Mwh.  Coal also helped, rising from 132,000Mwh to 204,000 Mwh in 2021, a rise of 72 Mwh.

When the frigid weather occurred coal & natural gas production of power surged ahead.  But wind power declined from  264,000 Mwh a year earlier, down to 73,000 Mwh.  

And the percentage figures show a similar pattern.  Natural gas was covering 65% of the power generation, and wind, only 6 % when the big freeze occurred.

That's a huge failure, and Wind shows up at the center of the power scarcity problem.  Regardless of all the rhetoric of the greenie media -- looking at other possible scapegoats.  Media were wrongly trying to divert attention away from the wind failure. 

Tomorrow I'll try posting here a couple of the charts from that reference.
