It reduces the&#xA;&gt; &gt; &gt; maximum energy price at which mining is profitable, reducing the energy&#xA;&gt; &gt; &gt; use.&#xA;&gt; &gt;&#xA;&gt; &gt; If people want to retain previous levels of security, they can offer to pay&#xA;&gt; &gt; higher fees, which increases the miner reward and thereby increasing the&#xA;&gt; &gt; energy use again.&#xA;&gt;&#xA;&gt; The turn-around time for that takes a population of both users and&#xA;&gt; miners to cause. Increasing popularity of bitcoin has a far bigger&#xA;&gt; impact here, and it is already raising fees and energy use at an&#xA;&gt; established rate.&#xA;&gt;&#xA;&gt; If it becomes an issue, as bandwidth increases block size could be&#xA;&gt; raised to lower fees.&#xA;&gt;&#xA;&#xA;Which increases block rewards somewhat (at least to some level that matches the overall security of the network) and you still have the same amount of energy consumed.&#xA;&#xA;&gt; &gt; Properly account for the entropy increase (energy usage) of all kinds of&#xA;&gt; &gt; pollution, and the free market will naturally seek sustainable and renewable&#xA;&gt; &gt; processes --- because that maximizes profitability in the long run.&#xA;&gt;&#xA;&gt; There is little economic incentive to fine carbon emissions because&#xA;&gt; there is no well-established quick path to gain profit from reducing&#xA;&gt; them. The feedback paths you describe take decades if not hundreds of&#xA;&gt; years.&#xA;&gt;&#xA;&gt; But it sounds like you are saying you would rather the energy issue&#xA;&gt; stay a political one that does not involve bitcoin. Your point is&#xA;&gt; quite relevant because bitcoin is not the largest consumer of energy;&#xA;&gt; those who care about reducing energy use would be better put to look&#xA;&gt; at other concerns.&#xA;&#xA;Precisely.&#xA;&#xA;&gt; &gt; What is needed is to enforce that pollution be paid for by those who cause&#xA;&gt; &gt; it --- this can require significant political influence to do (a major world&#xA;&gt; &gt; government is a major polluter, willing to pay for high fuel costs just to&#xA;&gt; &gt; ship their soldiers globally, polluting the environments of foreign&#xA;&gt; &gt; countries), and should be what true environmentalists would work towards,&#xA;&gt; &gt; not rejecting Bitcoin as an environmental disaster (which is frankly&#xA;&gt; &gt; laughable).&#xA;&gt; &gt; Remember, the free market only works correctly if all its costs are&#xA;&gt; &gt; accounted correctly --- otherwise it will treat costs subsidized by the&#xA;&gt; &gt; community of human beings as a resource to pump.&#xA;&gt;&#xA;&gt; It sounds like you would prefer a proof-of-work function that directly&#xA;&gt; proved carbon offsetting? And an on-chain tax for environmental harm?&#xA;&#xA;&#xA;The problem is that the only proof of efficiency here is implicit: any inefficiency will eventually be rooted out of the network, as any inefficiency will translate to reduced profitability.&#xA;However, at short-term, a miner can pollute its locality, and then exit the business and leave its crap lying around for others to deal with and abscond with pure profit.&#xA;This translates to a theft in the profitability of others in the locality.&#xA;&#xA;How to prove this is not happening?&#xA;The best you can do is to have some number of authorities sign off on whether or not they are doing this.&#xA;The problem is that authorities are bribeable.&#xA;&#xA;Alternately, other entities in the locality can use force to require the polluting entity to clean up or suffer significant consequences.&#xA;This at least is better incentive-wise, as they others in the same locality are the ones most affected, but the ability to enforce may be difficult due to various political constructions; the miners could be in such deep cahoots with the local government that the local government would willingly hurt other local entities in the vicinity of the polluting entity.&#xA;&#xA;&#xA;&#xA;Regards,&#xA;ZmnSCPxj</html></oembed>
