From The Daily Signal :
As Devin Hartman, the director of energy and environment policy for the free market think tank R Street Institute, wrote  this week:
Inoperable heating systems are a nuisance for a half hour. They are deadly for days. Unfortunately, this reality is evident in Texas.
This makes limiting the duration of customer outages arguably more important for public health than keeping the total number of outages down.
Per protocol, rolling blackouts cut off customers typically for about 20 to 30 minutes . Yet many Texans have been without power for days, while others never experienced an outage, even in the same metro area.
Why rotating blackouts aren’t rotating  is one problem policymakers should seek to fix.
