Life is not that simple, we do not always get what we want. Think of it as a simple business transaction or investment. If you are being specific about energy consumption and environmental impact of mining then there are many so-called eco-friendly coins out there, you should consider joining their project if it makes you feel you will meet your goals.
But I want PoW.
It's just that I don't like the impact on the environment.
All that energy has it's purpose, so what I am looking for is a better usage of that energy. Without compromising the competitive mining.
And now, from what I've learned, I have some thinking to do on how the aggregate mining cost fits the equation. We also want to reduce that.
