In recent years, a hot topic surrounding Bitcoin and proof-of-work mining have been their energy efficiency and the environmental impacts they generate.

On day three of the BSV Global Blockchain Convention, a panel moderated by CoinGeeks Patrick Thompson, including TAAL CEO Richard Baker, Alex de Vries from Digiconomist, Prof. Robert Lee from 518 Blockchain Community, and Kurt Wuckert Jr. from GorillaPool, discussed blockchain mining, the amount of energy it consumes, how to make blockchains more efficient, and more.

Who are the panelists?

How much energy does blockchain mining consume globally?

Thompson opens the discussion by asking de Vries to tell us how much energyblockchain miningconsumes globally. It makes sense to ask him since hes spent the last half a decade or more researching this both academically and independently.

If you add all crypto assets that can be mined together, youre probably talking at least as much as all global data centers in the world combined, de Vries tells us.

This includes all of the data centers for Meta, Amazon, Google, and other corporate giants, as well as the legacy financial system. He tells us that this accounts for more than 1% of global electricity usage and that BTC and Ethereum are responsible for most of this usage.

Thompson asks whether this is problematic, and Richard Baker answers that it is because policymakers look at the headlines, and amidst an energy crisis like were in right now, they have a responsibility to decide whether industrial and household energy needs should take priority over blockchain requirements. He notes how we already see policy in the European Unionand parts of the United States, which is considering a proof-of-work ban. However, he points out that not allproof-of-work blockchainsare the same, and we need to make sure that policymakers understand the utility of blockchains like BSV.

Does mining provide real value, or is it negative for society?

Wuckert is up next, explaining the value created by mining blocks. He highlights the value created by the internet and notes that the same scrutiny over energy usage isnt applied to things like AWS or other cloud computing systems. He then explains that in large (several GB) blocks, we can fit an incredible number of transactions, but that its difficult to judge the value of those transactions because theyre qualitative in nature.

Thompson then asks Professor Lee if blockchain mining has a net positive or a net negative outcome. He responds that if certain conditions are met; usinggreen energy, delivering utility, playing by the regulations, and paying taxes, then it can be a net positive, but otherwise, it will remain a net negative. De Vries answers the same question, saying that it depends. He notes that theres still a debate around whether proof-of-work is the only way to do things like peer-to-peer transactions. Even if proof-of-work is the only way, he says it becomes hard to justify eliminating the need for a trusted third party if the latter is more energy efficient.

Wuckert carries on from this question to explain thedifferencesbetween proof-of-work and proof-of-stake. He notes that inPOS systems, whoever holds the largest number of coins is king and that over time, their power over the network only continues to grow. By contrast, in proof-of-work, inefficient and malicious actors are pushed out, and the nodes that produce the most value flourish.

Miners on the move and how to improve efficiency

Thompson notes that with several high-profile crackdowns on mining in recent times, many miners are on the move. He asks Baker to tell him where most mining is occurring today, and he explains that its shifting towards North America. Weve seen $4.5 billion worth of hardware shipped into North America to power BTC this year, Baker tells us. However, he reminds us that not all states are miner-friendly, withNew Yorkbeing a good example of a state thats hostile towards blockchain miners.

Professor Lee elaborates on how miners can become more efficient to not draw the same ire from governments. He counts finding clean, renewable energy sources, using modern, efficient mining machines, and improving the efficiency of mining itself (e.g., by reducing cost per transaction) as ways to improve things.

Baker seconds Lees points, saying that miners will be subject to ESG regulations. He points out that the BSV network is becoming super-efficient withgrowing block sizes.

Wuckert draws attention to miners using excess energy such as gas flares in oil and gas fields as one way to use energy that would otherwise have been wasted. He also says that many miners use the heat from mining for other useful things, such as heating greenhouses.

Staying on the subject of renewable energy for mining, de Vries points out that the use of renewables has actually gone backward, at least on the BTC network. After the mass exodus of miners from China, many relocated to places likeKazakhstan, where energy is still mostly coal-powered. He says he doesnt know if thats also true for BSV as he has never examined it.

Is a ban on proof-of-work an effective solution?

Thompson then poses whether a ban on proof-of-work would solve the problems many politicians deem it to have? De Vries answers that there is no perfect solution and that miners will simply move to other jurisdictions. He reiterates that whenChina banned it, the carbon footprint went up, opposite the intended consequence.

Wuckert follows this by pointing out that when one jurisdiction bans something, it creates an opportunity elsewhere. He points out that the ban in China created opportunities in North America, and if New York bans it, it will create opportunities in Texas. This regulatory arbitrage will always be a factor, so bans are largely ineffective in the grand scheme of things.
