It reduces the&#xA;&gt;&gt; maximum energy price at which mining is profitable, reducing the energy&#xA;&gt;&gt; use.&#xA;&gt;&gt;&#xA;&gt;&#xA;&gt; If people want to retain previous levels of security, they can offer to pay&#xA;&gt; higher fees, which increases the miner reward and thereby increasing the&#xA;&gt; energy use again.&#xA;&#xA;The turn-around time for that takes a population of both users and&#xA;miners to cause.  Increasing popularity of bitcoin has a far bigger&#xA;impact here, and it is already raising fees and energy use at an&#xA;established rate.&#xA;&#xA;If it becomes an issue, as bandwidth increases block size could be&#xA;raised to lower fees.&#xA;&#xA;&gt; Properly account for the entropy increase (energy usage) of all kinds of&#xA;&gt; pollution, and the free market will naturally seek sustainable and renewable&#xA;&gt; processes --- because that maximizes profitability in the long run.&#xA;&#xA;There is little economic incentive to fine carbon emissions because&#xA;there is no well-established quick path to gain profit from reducing&#xA;them.  The feedback paths you describe take decades if not hundreds of&#xA;years.&#xA;&#xA;But it sounds like you are saying you would rather the energy issue&#xA;stay a political one that does not involve bitcoin.  Your point is&#xA;quite relevant because bitcoin is not the largest consumer of energy;&#xA;those who care about reducing energy use would be better put to look&#xA;at other concerns.&#xA;&#xA;The reason to reduce _bitcoin&#39;s_ energy use, would simply be to aid&#xA;its popularity and quell public concern.  Without doing this, people&#xA;move to an altcoin, because increasing the value of bitcoin via&#xA;spreading its use, increases the demand for mining.  That human&#xA;decision is part of the honesty you describe.&#xA;&#xA;&gt; What is needed is to enforce that pollution be paid for by those who cause&#xA;&gt; it --- this can require significant political influence to do (a major world&#xA;&gt; government is a major polluter, willing to pay for high fuel costs just to&#xA;&gt; ship their soldiers globally, polluting the environments of foreign&#xA;&gt; countries), and should be what true environmentalists would work towards,&#xA;&gt; not rejecting Bitcoin as an environmental disaster (which is frankly&#xA;&gt; laughable).&#xA;&gt;&#xA;&gt; Remember, the free market only works correctly if all its costs are&#xA;&gt; accounted correctly --- otherwise it will treat costs subsidized by the&#xA;&gt; community of human beings as a resource to pump.&#xA;&#xA;It sounds like you would prefer a proof-of-work function that directly&#xA;proved carbon offsetting?  And an on-chain tax for environmental harm?&#xA;&#xA;On 5/23/21, Anton Ragin via bitcoin-dev&#xA;&lt;bitcoin-dev at lists.linuxfoundation.org&gt; wrote:&#xA;&gt; Well, it is done automatically every 4 years :) It is a self-balancing&#xA;&gt; system - more people shout about Bitcoin being dirty -&gt; less adoption -&gt;&#xA;&gt; lower the price -&gt; less energy consumption. Add on top the fact that in&#xA;&gt; 2024 block rewards will fall 50% anyway and someday it will be zero.&#xA;&#xA;Is hashrate rising slower than the block reward is dropping, that you&#xA;mention the 4 years halving?  Do you see a problem with dropping the&#xA;block reward to make faster change to the hashrate curve, that you&#xA;mention the existing system&#39;s weaker approach?&#xA;&#xA;I personally wasn&#39;t aware that Elon had complained; I&#39;ve been hearing&#xA;the complaint from scads of people for many years.</html></oembed>
