Sometimes I feel like an atheist walking into a church.
I know I'm right, but nobody has an open mind.
I mostly agree with what you have posted here @coinycoiny. Don't forget that people will close their mind and grasp at any straw to protect what they perceive as their economic interests...often times this is done subconsciously. Lot's of what is being said reminds me of Big Tabaco trying to paint smoking as healthy or the Oil & Gas industry trying to confuse the climate change debate. What most BTC holders don't understand is that they can sell BTC and switch to a greener crypto that has more potential upside and less environmental baggage.
@fillippone All your defenses to accusation 1 basically say that other human activities also use electricity that emit greenhouse gases, so why pick on bitcoin. To someone who believes that GHG emission is leading us towards a climate disaster (i.e.
https://www.google.com/books/edition/How_to_Avoid_a_Climate_Disaster/pHK0DwAAQBAJ?hl=en&gbpv=1&printsec=frontcover), that’s like saying “Yes, your honor, I ______ (stole money, cheated on my taxes, beat my wife, etc.) but lots of my neighbors do the same thing.” It’s my believe that all industries need to get to net zero as soon as possible. Some are trying harder than others. People’s fascination with bitcoin put it in the news and its INCREASING CARBON FOOTPRINT put it in the crosshairs.
In 1.2 you say “According to data from the Cambridge Bitcoin Electricity Consumption Index devices kept on standby, in the United States alone, could power the bitcoin network for more than a year and a half. (a figure that has been constantly decreasing)” Are you saying that the number of years is going down? If so, that means that the amount of electrical consumption by standby devices is going down and/or the amount of power used by the bitcoin network is going up.
1.4 What gives you and other humans more enjoyment, watching bitcoin get mined or watching Netflix?
Your defenses to the Accusation that “Miners in China ravage the environment to produce Bitcoin. A large part of electricity production in China is made with fossil sources, especially coal, and the ecological footprint of Bitcoin is unsustainable” are more nuanced.
- 1. Environmentalists would say that it is a good thing and NOT A WASTE for coal to stay in the ground where it has sequestered carbon for many years.
2. Yes, SOME bitcoin mining uses green sources that would otherwise be wasted.
3. According to your link, one study estimated 72% of mining energy came from non-renewable sources (like coal and nuclear), while another, that you cited, had the figure at 61%. In either case, the majority is coming from unpopular sources that either emit GHG or produce hazardous waste that has to be stored for multiple generations.
4. Yes, bitcoin does help the profits of the energy industry.
5. Yes, there are ways for the energy industry to get more efficient. Some blockchain applications may help with this. See also 1.4 as many would say there are more beneficial ways to use computing power in the positive ways you suggest that the bitcoin network may be doing currently or in the future.
Accusation- “The Bitcoin network is maximally inefficient. PoW leads to the consumption of a huge amount of energy for each Bitcoin transaction if for example, we compare it with VISA.”
- 1.Aren’t there more energy efficient ways to secure a network?
2. Yes, miners are trying to use the most efficient computing power and lowest cost of energy, regardless of source. When minors upgrade from one computer source to another (or replace an ASIC) lots of e-waste is created.
3. Yes, lots of industries have negative externalities that should be better factored in. Emissions/Pollution fees that charges all polluters which is then returned equally to all individuals would help incentivize less pollution and be a net benefit to those that cause less than their fair share. As you mention with bitcoin, it is not just the transactions that lead to CO2 emissions, but also securing the network for anyone that holds BTC. This is why I suggested that governments may tax holders in cases where the miners are outside their jurisdiction (the rational being that those importing a polluting product should not get a free pass just because they don’t purchase locally). https://bitcointalksearch.org/topic/bitcoincrypto-carbon-tax-5323833
4. Yes, per the Bitcoin whitepaper, the system is designed to use lots of energy.
5. Again, two wrongs don’t make a right. Gold isn’t green either and should also be subject to pollution/carbon/environmental fees. My guess is that gold hasn’t exponentially increased its GHG emissions in the last 5 years like bitcoin, but they should still look to be going to net zero and pay for any negative externalities. There are those that object to gold (I.e. Now, https://www.earthworks.org/campaigns/no-dirty-gold/impacts/ and before bitcoin was in the crosshairs https://www.smithsonianmag.com/science-nature/environmental-disaster-gold-industry-180949762/) and the US prohibited the hording of gold in 1933 (albeit for economic and not environmental reasons). As a side note, if you stopped gold mining, the price might go up and additional ecological issues would be virtually eliminated (but long term effects of past mining would still present a problem)...with BTC, as you point out, the network relies on miners indefinitely for security purposes.
Yes, its unfair to single out bitcoin rather than have broad rules/fees/taxes that apply equally to everyone, but with more people concerned about climate change, no broad self-regulation from the bitcoin community on electrical sources, and the fact that electrical use is DESIGNED TO GO UP as the price goes up (regardless of how much utility it is providing), bitcoin will stay in the environmental crosshairs until something changes. Having control over money is power, and governments could certainly use bitcoin's environmental shortcomings as an excuse to regulate and take back that power if they feel BTC is a threat. Smarter for the crypto community to proactively find a greener horse to back (or for the bitcoin industry to clean up its act ASAP)
