Bitcoin promotes renewable energy.
Bitcoin reduces consumption.

Many of renewable energy potential lies far away from consumers and electricity highways. But those potentials can still be realized thanks to bitcoin mining. Bitcoin mining is converting energy into digital data that can be easily transferred via satellite internet, from any part of the world. So, all that unreachable renewable energy can already be monetized without waiting till when electricity highways be built.
For example there was project of building huge solar facility on Sahara desert, where there are no electricity highways, nor consumers around. Bitcoin mining is the easiest way to join global energy market for many underdeveloped nations.

With the rise of human population and economic prosperity, there is an unsustainable rise in general consumption. We are unsustainably consuming resources on Earth, causing enormous pollution of environment, causing human inflicted climate change, which will lead to more and more catastrophic cataclysms. The future on Earth is worrisome. Our economic and particularly monetary system promotes consumption. It is good for economy, bad for environment. What if we don't need to consume that much, what if we can live a modest life and still be happy? What if we can save to consume later when issues with environment are resolved?
Deflationary Bitcoin gives you that, it encourages you to save, the longer you save the more value you get. Inflationary fiat encourages you to spend now, because later it will be worth less. Don't be selfish, it is not only about you, but your children, grandchildren, entire offspring. Bitcoin is about being responsible for future.
