Bitcoin mining is still huge in China despite new ban in Inner Mongolia
Today, Bitcoin consumes as much energy as a small country. This certainly sounds alarming — but the reality is a little more complicated. How much energy does an industry deserve to consume? Right now, organizations around the world are facing pressure to limit the consumption of non-renewable energy sources and the emission of carbon into the atmosphere. As cryptocurrencies, and Bitcoin in particular, have grown in prominence, energy use has become the latest flashpoint in the larger conversation about what, and who, digital currencies are really good for.
On the face of it, the question about energy use is a fair one. This certainly sounds like a lot of energy. But how much energy should a monetary system consume? How you answer that likely depends on how you feel about Bitcoin.
If you believe that Bitcoin offers no utility beyond serving as a ponzi scheme or a device for money laundering , then it would only be logical to conclude that consuming any amount of energy is wasteful. If you are one of the tens of millions of individuals worldwide using it as a tool to escape monetary repression , inflation , or capital controls , you most likely think that the energy is extremely well spent. Specifically, there are a few key misconceptions worth addressing. While determining energy consumption is relatively straightforward, you cannot extrapolate the associated carbon emissions without knowing the precise energy mix — that is, the makeup of different energy sources used by the computers mining Bitcoin.
For example, one unit of hydro energy will have much less environmental impact than the same unit of coal-powered energy. But its carbon emissions are much harder to ascertain. Mining is an intensely competitive business, and miners tend not to be particularly forthcoming around the details of their operations. The best estimates of energy production geolocation from which an energy mix can be inferred come from the CCAF, which has worked with major mining pools to put together an anonymized dataset of miner locations.
Based on this data, the CCAF can guess about the energy sources miners were using by country, and in some cases, by province. Furthermore, many high profile analyses generalize energy mix at the country level, leading to an inaccurate portrait of countries such as China, which has an extremely diverse energy landscape.
As a result, estimates for what percentage of Bitcoin mining uses renewable energy vary widely. Almost all of the energy used worldwide must be produced relatively close to its end users — but Bitcoin has no such limitation, enabling miners to utilize power sources that are inaccessible for most other applications. Hydro is the most well-known example of this.
In the wet season in Sichuan and Yunnan, enormous quantities of renewable hydro energy are wasted every year. In these areas, production capacity massively outpaces local demand, and battery technology is far from advanced enough to make it worthwhile to store and transport energy from these rural regions into the urban centers that need it. Another promising avenue for carbon neutral mining is flared natural gas. The process of oil extraction today releases significant amount of natural gas as a byproduct — energy that pollutes the environment without ever making it to the grid.
But Bitcoin miners from North Dakota to Siberia have seized the opportunity to monetize this otherwise-wasted resource, and some companies are even exploring ways to further reduce emissions by combusting the gas in a more controlled manner.
To be fair, the monetization of excess natural gas with Bitcoin does still create emissions, and some have argued that the practice even acts as a subsidy to the fossil fuel industry, incentivizing energy companies to invest more in oil extraction than they otherwise might.
But income from Bitcoin miners is a drop in the bucket compared to demand from other industries that rely on fossil fuels — and that external demand is unlikely to disappear anytime soon. Given the reality that oil is and will continue to be extracted for the foreseeable future, exploiting a natural byproduct of the process and potentially even reducing its environmental impact is a net positive.
Interestingly, the aluminum smelting industry offers a surprisingly relevant parallel. Regions with the capacity to produce more energy than could be consumed locally, such as Iceland , Sichuan, and Yunnan, became net energy exporters through aluminum — and today, the same conditions that incentivized their investment in smelting have made those locations prime options for mining Bitcoin.
There are even a number of former aluminum smelters, such as the hydro Alcoa plant in Massena, NY, that have been directly repurposed as Bitcoin mines. How energy is produced is one piece of the equation. Once coins have been issued, the energy required to validate transactions is minimal. And that leads us to the final critical misconception: that the energy costs associated with mining Bitcoin will continue to grow exponentially. This was the premise of a widely-reported study that was recently cited in the New York Times , making the shocking claim that Bitcoin could warm the earth by two degrees Celcius.
First, as has become common in many industries, the energy mix of Bitcoin grows less reliant on carbon every year. In the U. And of course, as renewable options such as solar grow more efficient and thus more viable for mining, Bitcoin could end up serving as a serious incentive for miners to build out these technologies.
In addition, miners are unlikely to continue expanding their mining operations at the current rates indefinitely. The Bitcoin protocol subsidizes mining, but those subsidies have built-in checks on their growth.
However, the protocol is built to halve the issuance-driven component of miner revenue every four years — so unless the price of Bitcoin doubles every four years in perpetuity which economics suggests is essentially impossible for any currency , that share of miner revenue will eventually decay to zero. We can expect some miners to continue operating regardless, in exchange for these transaction fees alone — and in fact, the network depends on that to keep functioning — but if profit margins fall, the financial incentive to invest in mining will naturally decrease.

Energy Consumption of Bitcoin Mining
An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency. One mining operation in central New York came up with a novel solution that has alarmed environment alists. It uses its own power plant. Greenidge Generation runs a once-mothballed plant near the shore of Seneca Lake in the Finger Lakes region to produce about 44 megawatts to run 15, computer servers, plus additional electricity it sends into the state's power grid. The megawatts dedicated to Bitcoin might be enough electricity to power more than 35, homes.
Bitcoin Uses More Electricity Than Many Countries. How Is That Possible?
The year-long bear market finally forced many Bitcoin miners to capitulate by either scaling down or shuttering their operations. However, with the decrease in difficulty, some of these smaller establishments might want to get back into the business seeing as it is now easier to mine the top-ranked cryptocurrency. Back in , the cryptocurrency market was on a high. Almost everything from ICOs to miners was riding high on the back of steadily increasing virtual currency prices. Things even when several notches higher in Q4 as prices increased massively leading to all-time highs for many coins. However, winter came for the market, and a prolonged winter at that.
Some locals say a bitcoin mining operation is ruining one of the Finger Lakes. Here's how.
With their abundant renewable energy resources, Iceland, Sweden and Norway have all been popular locations for eco-friendly Bitcoin mining. But per the Economic Times , this could be set to change. As a result of rising climate challenges, these countries might soon turn their back on the crypto industry, as renewable energy is redirected to face more pressing challenges in the quest for a smaller carbon footprint. Sweden, Norway and Iceland have an abundance of geothermal, hydro, and wind power—energy sources that have long been touted as cheap renewable options for Bitcoin miners. In contrast, Chinese mining is dominated by coal. In fact, the decline in Bitcoin mining is already evident in Norway. Bitcoin mining is the process by which new Bitcoin is created.
5 Popular ASIC Miners for Bitcoin Mining in 2019
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity.
A technician works at the Bitfarms bitcoin mine in Magog, Que. As the price of bitcoin soared over the past 14 months, Hut 8 was suddenly swimming in far more revenue than it ever had, opening up new doors for one of the oldest and largest digital asset miners to innovate, Ms. Leverton told The Globe and Mail in a recent interview. Many have seen their stock prices skyrocket, revenue and profits soar, prompting a healthy inflow of capital that is subsequently deployed into various new ventures in the cryptosphere. In a way, the maturation of crypto miners makes sense — it corresponds to the explosive, unbridled growth of anything associated with blockchain technology, a mania that some have previously termed speculative, geared just for the rich , and even worthless.
