I don't endorse POW (proof of work) cryptocurrency and barely POS(proof of statke). Really what I might endorse is the underlying distributed ledger and potential for Smart Contracts...
However- this is an interesting example of less than fully egregious bitcoin mining contexts: https://www.oceanfallsblockchain.com Conservation of energy would suggest that the extraction of electrical power from flowing water, subsequent negEntropy extraction and then re-introduction of the same energy back into the flowing water (as heat) is *relatively* benign. The very fact of the hydro-dam (built there some big part of a century ago) has it's own ecological impacts (salmon, the bear who eat them, the rainforest that likes those nutrient-rich gifts the bears leave on the forest floor), but no net energy or CO2 challenges? In principle, this hydro power *could* have been sent a hundred miles or more over copper power lines (including resistive load losses) to feed our *other* power-hungry appetites? It seems like energy-flow changes are fairly localized (the energy dissipated from an unimpeded river flow would have also been converted almost exclusively to heat to be carried away in the water? What of the Entropy? Was useful negEntropy somehow extracted and effectively "wasted" by dumping it into a Proof of Work distributed ledger representing BitCoin value? One could argue that there are much better uses of this negEntropy than inflating a strange Ponzi Bubble? My Father used to make the apology/excuse for his relative's moonshining as the most efficient way for folks on the inland side of the Cumberland Gap to monetize their ability to produce, process and deliver crops (i.g. corn) to market. Where farmers on the seaboard side could sell their corn, it was prohibitively expensive to haul corn to the Virginia Markets from W.VA and KY, but distilled "corn squeezin's" represented concentrating the "value" out of the sun falling on the corn, etc. The hydropower from the Great Bear waterhsed, would seem to be mined of it's negEntropy to create "value" in the form of BitCoin. I don't expect POW to continue much longer in the shadow of POS. I also wonder if when/if/as BitCoin value is maxed if the energy use will drop radically. Absent mining new coin, doesn't BitCoin operation degenerate to the same energy cost (covering transactions only) as other (POS) blockchain implementations?
