I think there is hope, especially now that the world is witnessing the danger of relying on oil, that needs to be transported through a war-zone.

Here is another good sign:

China is the #1 polluter in the world, but it has been shifting towards renewables in a major way:
~40% of China’s electricity in 2025 came from renewable sources (solar and wind).
Emissions slightly decreased in 2025, even though energy demand grew.
Coal power output declined for the first time in a decade.

Of course this isn't enough, China is still the biggest polluter, despite all these changes. Oil producing countries and the US are the next on the list. And sadly they are way too invested in Oil to shift to renewables.
