What is important about this piece is not what it says, but who is saying it...
What is said is a very mealy mouthed backtracking of the climate alarmist perspective covering only the most obvious aspects of what went/is going wrong and then tip-toeing around the fact that it went wrong.
WHO: Yergin is the ultimate establishment, insider expert on the oil market who in the past was primarily in charge of explaining why the price of oil should go lower and thus support the banksters/establishment of the non-OPEC+ plus oil consuming countries as they manipulate the price of oil lower.
The fact that he is backtracking means a very significant faction within the establishment is distancing themselves from the failed alarmist policies. The policies that, by blocking all fossil fuel production, we must transition no matter what by 2030. Its a significant shift for Yergin and his supporters.
Now, who is in this faction? Tom Luongo says its led by the US banksters (Jamie Dimon, etc. ) although it obviously has support from red states and some republicans and probably the military industrial intelligence community who know that strangling the US and allied western European economies with un-competitive overpriced wind and solar energy is bad for US hegemony.
