Why Bitcoin Is The Future Of Our Power Grid


Bitcoin’s distinctive power use incentives, means to retailer stranded power and extra make it the way forward for our power consumption as a planet.

Right here goes a full-length, easy-to-read article primarily based on my latest Twitter thread, half one on Bitcoin and the nuclear way forward for our power grid. Partially one, I breakdown the narratives round power markets on the whole and Bitcoin’s power utilization, cowl some trade info and insights and supply a few of my private opinions alongside the best way for a hopefully satisfying learn.

However earlier than I start, I wish to present my very own little background because it’s related to the subject immediately. I am a chemical engineer by diploma (BS and MS) and have been working as a lead engineer within the superior nuclear expertise area for the previous couple of years, so this matter seems like residence.

I wish to give a shoutout upfront to a few of the references I exploit and cite from under. None are larger or higher than Lyn Alden — I take charts and data from her latest e-newsletter to cowl part of this thread, everybody ought to go learn it right here.

The opposite sources I am going to cite from are the next (in no specific order):

  1. “Bitcoin Mining Council Q2 2021 Report
  2. Sq.’s paper on Bitcoin’s power utilization
  3. “Solely The Sturdy Survive” by Allen Farrington

Having obtained this out of the best way, let’s get into it by ranging from the fundamentals. What is the innovation in Bitcoin? Right here’s a listing I like, taken from Farrington’s latest article:=

  1. The proof-of-work algorithm
  2. The problem adjustment
  3. The native financial unit that is ready to endogenously emerge
  4. Socially, the innovation is an immutable and uncheatable distributed ledger

To realize this, Bitcoin must have a tie in to the bodily world: power. Power expenditure is the tie in between the true world and the digital world. Henry Ford proposed this in 1921, to have a foreign money backed by power for the world.

Ford proposed the next design criterion for a common cash which might free the world again in 1921:

  1. Backed by power
  2. Unconfiscatable
  3. Fastened provide
  4. Exterior authorities management

There was nothing that glad these design standards earlier than, till bitcoin got here alongside. Bitcoin is an engineering breakthrough. It will grow to be the best invention/discovery of human historical past as soon as we people catch as much as its brilliance. I deal with it as akin to the invention of fireplace by the early people which pushed civilization alongside.

Michael Saylor coated this with Robert Breedlove on the latter’s present. He went by means of human discoveries which have been essential to the development of civilization as an entire and put Bitcoin in that bracket.

Now that we have got that out of our approach, let’s undergo power first and put Bitcoin’s power utilization in relative phrases to the world’s whole power consumption. The world makes use of barely north of 173,000 terawatt hours (TWh) of power per yr. Is that each one the accessible power for us people?

No. Have a look under as U.S. power consumption in 2020, for instance. Out of 92.9 quads of power accessible, solely 30.6 quads get put to make use of for power providers. So nearly two-thirds is rejected power for a number of causes. If we change into extra environment friendly, we will extract much more.

Additionally, there are lots extra sources of power coming on-line and being labored upon, which will increase the whole accessible power provide sources much more. So, in a nutshell, there’s an honest quantity of power getting used, lots being wasted and extra to return on-line.

Now, how a lot is Bitcoin’s power expenditure used to keep up proof-of-work consensus? Per the College of Cambridge, Bitcoin’s (peak) annualized power consumption fee is round 103 TWh at the moment, and was as excessive as 190 TWh earlier within the yr, because of the exodus of bitcoin mining from China this yr.

How a lot is 103 TWh in comparison with 173,000 TWh? That is 0.06%. That is it. Even for those who take the 190 TWh from earlier within the yr, it is nonetheless solely about 0.1%. So, Bitcoin makes use of solely one-tenth of 1% of the world’s whole power. That is it. Let’s get this one reality proper.

Bitcoin’s power use is just a rounding error relative to international power utilization. Scientists who typically provide you with power utilization numbers for the world can simply be off by 1% to 2% in both path, and we’re speaking one-tenth of that right here. Merely little or no.

Would Bitcoin’s power utilization go up over time? Sure. If bitcoin turns into profitable in turning into the “power foreign money” of the world, it is power expenditure has to rise to defend the proof-of-work consensus and the community. If its worth to people will increase, so would its power use.

However Bitcoin’s power will without end be a rounding error relative to international power consumption numbers. We’ll undergo the mathematics later, however it’s power utilization will not exceed its long-run utility (nevertheless giant or small it turns into over time). Alden coated this in her article cited above amazingly.

Now, what is the mainstream media telling you? See under a telling excerpt. You see these kind of messages on a regular basis. We simply established above that they don’t seem to be true in any respect. If something, Bitcoin makes use of too little power for its relative utility for the world immediately as we’ll set up subsequent. The mainstream media is gaslighting you.


Earlier than we dive into a few of the power math, let’s level a few of bitcoin’s utility to the world immediately. Bitcoin gives:

  1. A hard and fast provide onerous asset that gives a retailer of worth/wealth
  2. Unconfiscatable personal property rights
  3. A censorship-resistant, permissionless, peer-to-peer medium of change
  4. Essentially the most decentralized financial community exterior of the management of any central authority or nation state (resilient to assaults)
  5. One of the best type of bearer asset (pristine collateral)
  6. A frictionless, borderless, immediate, low value, international funds community ( through the Lightning Community, a Layer 2 answer constructed on high of Bitcoin)

Do you assume one thing with these properties, the toughest type of cash backed by power, can have any type of utility for people going ahead on the planet we reside in immediately? If the reply is sure (which I hope it’s), than 0.1% of the world’s power utilization is nothing and is definitely justifiable.

Let’s transfer on then to a few of Bitcoin’s power math. First, let’s set up how bitcoin even consumes power. Like, how does this proof-of-work consensus mannequin work? What does it even imply to mine bitcoin? Like, WTF is all this?

Merely talking, bitcoin’s proof of labor is designed to provide one “block” each 10 minutes. A brand new block is produced by fixing a math puzzle, by brute forcing it utilizing computational work and due to this fact, you guessed it, electrical energy or power.

Power expenditure is vital to producing blocks and proof of labor. In a approach, Bitcoin is backed by power, expended to safe the community by the miners who go about producing these blocks. Though they do not management the community, as was demonstrated within the blocksize wars.

The puzzle is designed as such that one block is produced roughly each 10 minutes. If it takes much less time to provide a block, the puzzle will get more durable to unravel, whereas if it takes extra time to provide a block, the puzzle will get simpler. That is the “issue adjustment” innovation which is vital to Bitcoin. By no means in historical past have we had an asset whose provide is completely unbiased of demand, pre-programmed, engineered to precision and set in code, immutable by any central authority.

Now, because of the incentive mannequin constructed into the community, tens of millions of machines are deployed to “mine” Bitcoin blocks by providing computational energy to the community, or “power.” That is measured in one thing known as the “hash fee” which is at the moment at 166 exahashes per second (EH/s).

What do the miners get in return for offering this power? They get block rewards, which consists of two issues: the block subsidy and transaction (tx) charges. Bitcoin block subsidy follows a four-year halving cycle (one thing you might need heard of from the chart analysts).

The block subsidy was 50 bitcoin per block when it began again in 2009, and dropped to 25 bitcoin 4 yrs later, then 12.5 bitcoin 4 extra years later, and lately dropped to six.25 bitcoin final yr, in Could 2020. That is the one approach new bitcoin can come into existence, so take into consideration the availability shock.

The community instantly tells the miners seeking to mine bitcoin, “Hey, from immediately you may solely get one-half of what you used to get, and in 4 years it will be one half of that and so forth.” That is an incredible quantity of provide shock to the market itself.

We have seen prior to now that bitcoin’s value rise has been linked to those “halving cycles” due to the inherent provide shock that comes together with it. As some say, “quantity go up” is constructed into the consensus mannequin itself.

Now, sufficient of the mining rewards. We have been speaking power utilization, weren’t we? If we assume the market cap of bitcoin within the open market is how a lot worth is locked onto the community, which means that is how priceless bitcoin is to us people, then we will desk the power expenditure, or in different phrases “safety spending” (power) as a share of bitcoin’s market cap to see if the community is getting power environment friendly over time or not. The much less the proportion, the extra environment friendly the community is turning into, merely talking.

Let’s take the whole block reward, i.e., block subsidy and tx charges, as a proxy for safety spend on the community. This isn’t precisely true, because the safety spend is just the electrical energy value or power expenditure, which is a share of this reward. So, that is in reality an higher certain measure.

As we see, the annual safety spend has gone up over time in USD phrases, however as a share of bitcoin’s market cap, it’s been falling ever since 2011. Within the first half of 2021, it sat at lower than 2% of the market cap, as Alden identified in her article. That is precisely what the analysts don’t get.

Bitcoin is turning into extremely power environment friendly over time. It is utilizing actually fractions of the worth of the community to safe it (at the moment at 2%). There’s one other halving coming in 2024 which brings the block subsidy down to three.25 bitcoin, and the one in 2028 will convey it to 1.625 bitcoin.

As you see, the safety spend over the approaching decade will hold getting reduce quick by this halving of the block subsidy. For certain, extra of the spend will probably be coated by the tx charges going ahead. Alden’s expectation is to see the spend at 0.25% to 1%, relying on tx payment ranges.

Listed below are some projections for safety spend as a share of bitcoin’s market cap within the years to return. For instance bitcoin reaches $1 million (or a few $20 trillion market cap) by 2025, and after 2024, halving safety spend now goes right down to say 0.5%, in order that’s a spend of $100 billion. The present spend is $16.5 billion.

That will imply that Bitcoin’s whole power utilization in 2025 can be about 0.6%, or six occasions immediately’s utilization solely. And be mindful, safety spend shouldn’t be precisely the identical as power expenditure, which is a share of it and, secondly, the whole power utilization of the world goes to go up as nicely.

For a straightforward math equation, we’re nonetheless under about 1% of whole world power utilization to safe the community, even at some extent the place $20 trillion of world’s financial power will probably be secured within the community itself. That is tremendous low power utilization for one thing of such grand utility, wouldn’t you say?

Here’s a comparability of Bitcoin’s present power use to different industries and its CO2e emissions as nicely. As we have gone by means of the numbers earlier than, bitcoin’s power use is a rounding error as of now. Nothing so as to add right here.

Now, having established Bitcoin’s power use numbers, let us take a look at the power mixture of present utilization. As reported by the Bitcoin Mining Council’s quarter two report, Bitcoin’s power combine is probably the most sustainable on the market and is considerably extra so than most nations.

Mainstream media paints an image that bitcoin miners are competing with different industries for electrical energy, as if it might push another person out of their power utilization. This isn’t true. Bitcoin miners go in search of the most affordable supply of electrical energy on the market. Why? As a result of that’s nearly all of their every day operation prices of operating the miners. They merely can’t compete with the opposite miners on a world scale with moderate- to high-cost electrical energy costs charged for regular customers. So, they don’t seem to be your opponents.

Bitcoin miners search to seek out provide versus demand inefficiencies within the energy markets and search for underutilized or wasted sources of power to achieve a aggressive benefit over different miners by securing a low value of power. This can be a international hunt in all places.

People have by no means organized themselves round an power supply, at the very least that is not been the key driver of human settlements. You typically see power being transported and delivered to them, as an alternative of them settling round power.

Bitcoin miners are uncommon on this approach. They’ll go wherever the place the power is least expensive to mine. Listed below are some uncommon snippets about them:

  • They’ll collocate on the supply of electrical energy technology
  • They’ll devour intermittently with out harming their core enterprise
  • Power value is like 80% to 90% of their operations value
  • All they want is offered land and an web connection (mobile or satellite tv for pc)
  • They’re consumers of any stranded sources of power, something under 6 cents per kilowatt hour (kWh)
  • They’ll make new power tasks economically viable

That seems like an extremely fascinating bunch of individuals to review a bit of bit extra. Like, who’re these freaks? Any anecdotes? Okay let’s dig in a bit extra and get some proof of those uncommon set of people and why I name them “stranded power hunters.”

China had been the largest mining nation for a very long time till 2021 after the China mining ban and mass exodus of miners from their provinces over the previous couple of months. The province of Sichuan is exclusive. It has a ton of over-built hydroelectric capability which works wasted.

Through the moist season, it produces extra power than it could actually use. So, these Chinese language bitcoin miners flocked to Sichuan to seize that stranded or wasted power to mine bitcoin as an alternative. Just because, sure, there are incentives to seek out the most affordable power attainable to mine.

What would occur to this power if that they had not used it to mine bitcoin? It could have simply gone to waste. Bitcoin miners turned that stranded power right into a income. Most of those miners at the moment are flocking to the West in gentle of the mining ban in China.

Have a look at Bitcoin’s hash fee once more. See that huge drop of greater than 50% in hash fee after the China mining ban? Nicely, guess what: It’s nearly again as much as the place it was earlier than. Discuss how resilient this community is. No single level of failure, no single nation controls or governs it.

Here is one other instance: “flared gasoline mining.” Many oil fields have trapped pure gasoline related to them. Sometimes, these drilling websites are far out and don’t have any linked pipelines by means of which you’ll be able to transport and promote this gasoline, whether it is even in affordable portions to promote.

With pure gasoline costs so low, it doesn’t make sense to spend money on pipelines or associated infrastructure to move them. So, what are the choices? Vent it within the open ambiance or flare it. The primary choice vents methane, the latter, CO2. In what portions? 1.48 billion cubic toes, or 150 TWh per the U.S. EIA. And that is solely within the U.S. in 2019, not even worldwide.

Bear in mind how a lot power the Bitcoin community makes use of immediately? 100 TWh. So, you may energy your entire community and extra by merely capturing this stranded gasoline which is flared as an alternative. Would this even be useful to the atmosphere? Completely.

Now, here is an important one, which is my favourite: The idea of “Bitcoin as an power battery.” The primary time I heard of this was from this text. Nick Grossman wrote about how Iceland transports its huge quantities of geothermal power to the world by aluminum. Iceland makes use of its renewable geothermal power, which is in any other case stranded because it’s tough to construct pipelines to it underneath the Atlantic, to smelt aluminum, after which they transport aluminum to the world. So, in a approach, they’re transporting power. Aluminum serves because the battery.

Like, what’s even an power battery? One thing that may transport power throughout each area and time. Nicely, guess what? That is precisely what Bitcoin is. And it’s a lot better at it than actually anything on the planet. It’s probably the most liquid type of power battery, one thing that may run 24/7 in a permissionless, frictionless, borderless, unconfiscatable, resilient, power conserving, power-dense type of battery. Would not or not it’s clever for Iceland to mine bitcoin as an alternative of utilizing its geothermal for aluminum? Sure.

Electrical grids steadiness two issues: provide and demand. Only a few sources of power can run 24/7 uninterrupted. Nuclear energy is one of the best one. Photo voltaic, wind and hydro energy are all variable relying on climate circumstances. Because of this variability, grids are over constructed on the availability aspect.

Demand from the shoppers varies as nicely, particularly season to season and between day and evening. You get durations of peak calls for in between. So, you have to cater to this variable demand. Therefore, it’s at all times a steadiness that the grids want to keep up.

One large downside with intermittent sources of power like photo voltaic and wind is storage. They’re merely not dependable as base load with out power storage. And power storage shouldn’t be a straightforward downside to unravel. Guess what: We could have an engineering choice on our hand in Bitcoin.

The chart under reveals the power return on funding (EROI) for power sources. In case you can see how it’s at the moment, photo voltaic/wind don’t even meet the power threshold with storage prices included.

Nuclear energy has a 75-times EROI with no power storage value. It’s merely one of the best power supply we have now accessible on the planet, and but we hold shutting down our nuclear energy vegetation. Why? Once more, mainstream media narratives and sure accidents prior to now have modified public opinion. However the info are there.

Different renewable types of power might do with Bitcoin as their power storage choice to decrease their value of storage and change into economically extra viable as tasks for investments. Bitcoin miners will help make superior power expertise tasks economically-viable choices.

Bitcoin miners can function first prospects and consumers of final resort for these superior power expertise options and assist get them with long-term funding capital to make them succeed. As we have seen all alongside, Bitcoin and power are intricately intertwined.

For my part, Bitcoin will lead us right into a Kind I Kardashev civilization, one that may use and retailer all the power accessible on its planet. Immediately, we’re a Kind 0 Kardashev civilization, and this course of can take years to play out. I is probably not right here to see it in particular person.

Let’s do some fast takeaways then from this text earlier than we wrap up:

  1. Bitcoin has nice utility and is vital for people. Not everybody might use or admire its utility immediately, which is okay, however that doesn’t imply it doesn’t maintain utility to others. Presently, near $1 trillion of the world’s wealth is saved in it, that’s numerous financial power to ignore.
  2. Bitcoin makes use of solely about 0.1% of worldwide power. Present power utilization is between 100 TWh per yr to 200 TWh per yr and, per our projection’s math, Bitcoin’s power utilization will at all times be a rounding error close to international power consumption. It could probably be sub-1% for a very long time to return.
  3. Bitcoin, in reality, might use too little power for the worth it could retailer sooner or later. Contemplating bitcoin grows over this coming decade and shops $20 trillion of the world’s wealth, possibly even $50 trillion, or, dare I say, $100 trillion, that’s numerous financial power to be secured safely and guarded. We must always make investments and use extra power to guard the community than what we do at the moment.
  4. Bitcoin miners are extremely cellular and search for the most affordable and lowest-cost power to mine.
  5. Bitcoin miners don’t compete with different industries or your private use for power.
  6. Power utilization is an efficient factor. You in all probability wish to reside in a spot the place there’s a good quantity of power accessible to make use of and luxuriate in, somewhat than too little. We have to use and harness extra power to change into a Kind-I civilization, which is able to take a long time.

There are numerous gadgets that I didn’t cowl on this article, which I am planning to put in writing on as a extra detailed observe as much as this. I needed this to be an introductory article.

My focus of the following one can be a deep dive on power markets, power grid construction, the synergy between next-generation molten salt nuclear reactors and bitcoin mining, and an entire lot extra of Bitcoin power math and future projections. In case you favored studying this, do let me know on Twitter, I admire any suggestions. Thanks for spending time going by means of this.
