Saving energy means stopping growth. The West stopping growth while China, India, etc. grow uncontrollably because they don't give a crap about the stupid climate plight will be our downfall.
This is hypocracy, ignorance, and whataboutism
China is on track to meet it's climate goals, 90% of electric busses in the world operate there, they have been top investor in renewables for many years. And they are still growing.
Why do you never mention gulf states that emit 10 times more than an average french person does.
Meanwhile UK has refused planning permissin for 24 privately funded and paid for solar farms because they look ugly, banned onshore wind because it looks ugly and getting applorval for simplest construction project takes 4 years.
The climate plight will be our downfall, but not because of silly squabbles like you describe, but because the mindset you have is inherently extinctionist.
Uncontrollable growth is a characteristic of cancer, not something to aspire to.
