My colleagues eat in twilight (eating area didn't have windows) to lower the energy consumption and limit CO2 release. Yandex is burning 12000 liters of diesel to power their data center for an hour.
For the mostpart this lifestyle makes me
1) Poorer
2) Ostracised
There is no reward structure that favours doing the right thing. For me, these positive lifestyle choices have to be their own reward. Unfortunately that makes me see my society, which rewards conspicuous greed and selfishness as beneath contempt, and that's not a nice feeling.
This is why I am pessimistic about humanity’s future. We need to make systemic changes, but those who benefit from the system will never voluntarily agree to give up that power, even if it means doom for themselves and the rest of us.
...and many people I know think I'm ridiculous. Honestly I feel like I'm doing the minimum. All these things do is inconvenience me. I'm not expecting an award (outside of my kids not experiencing global famine) but no one gives a shit.
I fully expect not enough to be done until people are starving to death. And at that point I still don't expect anything to happen... the wealthy will live with some minor inconviniences and the poor will die.
The rest is the problem with how we generate our energy.
There are so many more and better optimisation that can be made, on the individual, communal and societal level.
