To Journalists, Investors, Regulators, & Anyone Else Interested in Bitcoin & the Environment,
Thanks for your inquiry. I thought I would share a few high level thoughts on Bitcoin Mining & the Environment.
1. Bitcoin Energy Utilization: Bitcoin runs on stranded, excess energy, generated at the edge of the grid, in places where there is no other demand, at times when no one else needs the electricity. Retail & commercial consumers of electricity in major population areas pay 5-10x more per kwH (10-20 cents per kwH) than bitcoin miners, who should be thought of as wholesale consumers of energy (normally budgeting 2-3 cents per kwH). The world produces more energy than it needs, and approximately a third of this energy is wasted. The last 15 basis points of energy power the entire Bitcoin Network - this is the least valued, cheapest margin of energy left after 99.85% of the energy in the world is allocated to other uses.
2. Bitcoin vs. Other Industries: Bitcoin mining is the most efficient, cleanest industrial use of electricity, and is improving its energy efficiency at the fastest rate across any major industry. Our metrics show ~59.5% of energy for bitcoin mining comes from sustainable sources and energy efficiency improved 46% YoY. No other industry comes close (consider planes, trains, automobiles, healthcare, banking, construction, precious metals, etc.). The bitcoin network keeps getting more energy efficient because of the relentless improvement in the semiconductors (SHA-256 ASICs) that power the bitcoin mining centers, combined with the halving of bitcoin mining rewards every four years that is built into the protocol. This results in a consistent 18-36% improvement year after year in energy efficiency. More details on this are included in the BMC Presentation.
3. Bitcoin Value Creation & Energy Intensity: Approximately $4-5 billion in electricity is used to power & secure a network that is worth $420 billion as of today, and settles $12 billion per day ($4 trillion per year). The value of the output is 100x the cost of the energy input. This makes Bitcoin far less energy intensive than Google, Netflix, or Facebook, and 1-2 orders of magnitude less energy intensive than traditional 20th century industries like airlines, logistics, retail, hospitality, & agriculture.
4. Bitcoin vs. Other Cryptos: The only proven technique for creating a digital commodity is Proof of Work (bitcoin mining) deployed in a fair, equitable fashion (i.e. no pre-mine, no ICO, no controlling foundation, no primary software development team, no series of forced hard fork upgrades that materially change the monetary protocol). If we remove the dedicated hardware (SHA-256 ASICs) and the dedicated energy that powers those mining rigs, we are left with a network secured by proprietary software running on generic computers. That places all security & control of the network in the hands of a small group of software developers, who must create virtual machines doing virtual work with virtual energy in a virtual world to create virtual security. All attempts to date have resulted in a digital asset that meets the definition of an investment contract (i.e. digital security, not digital commodity). They all pass the Howie test and therefore look more like equities than commodities.
Regulators & legal experts have noted on many occasions that Proof of Stake networks are likely securities, not commodities, and we can expect them to be treated as such over time. PoS Crypto Securities may be appropriate for certain applications, but they are not suitable to serve as global, open, fair money or a global open settlement network. Therefore, it makes no sense to compare Proof of Stake networks to Bitcoin. The creation of a digital commodity without an issuer that serves as “digital gold” is an innovation (we have accomplished this only once in the history of the world with Bitcoin). The creation of a digital security or digital coupon on a shared database is utterly ordinary (it has been done 20,000 times in the crypto world, and 100,000+ times in the traditional world).
5. Bitcoin & Carbon Emissions: 99.92% of carbon emissions in the world are due to industrial uses of energy other than bitcoin mining. Bitcoin mining is neither the problem nor the solution to the challenge of reducing carbon emissions. It is in fact a rounding error and would hardly be noticed if it were not for the competitive guerrilla marketing activities of other crypto promoters & lobbyists that seek to focus negative attention on Proof of Work mining in order to distract regulators, politicians, & the general public from the inconvenient truth that Proof of Stake crypto assets are generally unregistered securities trading on unregulated exchanges to the detriment of the retail investing public.
6. Bitcoin & Environmental Benefits: There is an increasing awareness that Bitcoin is quite beneficial to the environment because it can be deployed to monetize stranded natural gas or methane gas energy sources. Methane gas emissions' curtailment is particularly compelling and Dan Batten (https://batcoinz.com/) has written some impressive papers on this subject. It has also become clear that energy grids that rely primarily on sustainable power sources like wind, hydro, & solar can be unreliable at times due to lack of water, sunlight, or wind. In this case, they need to be paired with a large, flexible electricity consumer like a bitcoin miner in order to develop grid resilience & finance the buildout of additional capacity necessary to responsibly power major industrial/population centers. The recent example of major Bitcoin energy curtailment on the ERCOT grid in Texas is an example of the benefits of bitcoin mining to sustainable power providers. No other industrial energy consumer is so well suited to monetize excess power as well as curtail flexibly during periods of energy shortfall & production volatility.
7. Bitcoin & Global Energy: Bitcoin maximalists believe that Bitcoin is an instrument of economic empowerment for 8 billion people around the world. This is supported by the ability of a bitcoin miner to monetize any power source, anywhere, anytime, at any scale. Bitcoin mining can bring a clean, profitable and modern industry that generates hard currency to a remote location in the developing world, connected only via satellite link. All that is needed is some excess electricity generated from a waterfall, geothermal source, or miscellaneous excess energy deposit. Google, Netflix, and Apple won’t be setting up data centers in Central Africa that export services to their wealthy western clients anytime soon due to constraints on bandwidth, privacy, & requirements for consistent power flow, but bitcoin miners are not hampered by these constraints. They can utilize erratic power supplies with low bandwidth in remote locations and generate valuable bitcoin without prejudice, just as if they were in a suburb of NYC, LA, or SF. Even now, Bitcoin miners are everywhere and will continue to spread (though Africa, Asia, South America, etc.) wherever there is excess energy and anyone with aspirations for a better life. Bitcoin is an egalitarian financial asset offering financial inclusion to all, and bitcoin mining is an egalitarian technology industry offering commercial inclusion to anyone with the energy & engineering capability to operate a mining center.
