If we made the green energy transition this war would be unthinkable and these authoritarians wouldn’t be in power — not in the US, not in Iran, not in Saudi Arabia, not in Russia. Hydrocarbons are killing our freedom and just plain killing us.

Eine Cartoon-Zeichnung zeigt eine Straßenszene mit einem Zebrastreifen, auf dem Zahlen als Figuren mit Augen und Armen gehen. Links steht die Zahl 6 und sagt in einer Sprechblase „AFTER YOU…“ zu der vor ihr laufenden Zahl 3,1415, die den Beginn der Kreiszahl Pi darstellt und sich nach hinten umdreht. Die 3,1415 führt eine sehr lange Schlange weiterer Ziffern an, die sich wie eine endlose Reihe über den Zebrastreifen erstreckt. Unter der Szene steht der Text „A DECISION SHARON CAME TO REGRET“, was andeutet, dass Sharon (die 6) ihre Höflichkeit bereut, weil sie nun hinter der unendlich langen Zahl Pi warten muss.
