This is race-to-the-bottom thinking. All forms of civilization needs energy. More is better. Characterizing it as "obscene" smacks of anti-humanism and is completely wrong-headed.
We need to use more energy - a billion times more. We just need it to be clean.
If we have a future where governments decide what is good energy vs bad energy use instead of clean or dirty energy production, then we will really enter a deep new dark age of human civilization.
It's possible I used the word slightly wrong as the definitions I've now looked up often refer to the "middle class", though as I understand that could historically refer to people who we'd think of now as very upper class, just not actual nobles. Nevertheless, the above reading is what I intended
The major religion in the West for the past two thousand years teaches the concept of original sin and goes on about how we're inherently bad, in need of saving, wealth is bad, etc.
Now we have a lighter version of that with this new wave of secular anti-humanism. At least there is some slow, grinding progress.
Interestingly, Nietzsche predicted all of this in the Genealogy of Morality.
