The Chinese miners do have the larger equipment, larger mining power, larger power consumption and yet has the greener and lesser cost per kW/h. It shouldn't be a matter of $ in the long run since you know, we burn too much fossil fuels to have electricity and we are here, trying make money out of burning something most of the time but hey, $ is more important than this world itself. But anyways, mining is becoming more and more efficient as we progress and look for greener ways to mine bitcoin and that is really, really good if you might ask me.
That is an interesting concept. I had some idea related green or, at least, greener equipment solution in the past, but I did not get much support related it. Maybe the trend is changing now, but in my experience people prefer the familiar solution over an innovative, but young technology. It is a kind of paradox since BTC is an innovative, alternative technology too but factors are changing when someone starts to look at BTC as a continous business instead of a long-term investment. Anyway, how are these Chineese miners "greener"? Never heard about this claim.
