The other thing about the Texas energy fiasco is an unintended consequence of deregulation. The power companies in an effort to compete kept lowering their fees to the point that they could no longer afford repairs and purchasing items they thought they might not need (like heated turbine blades).
The result was an underfunded grid. It was not an issue if everything went well and was normal. But the freezing cold spell that hit was NOT normal (though it might be in the future) so the system failed. Motto? be careful what you wish for. Lower electricity and heating bills? Now there are major blackouts – no electricity and no heating.
