Bitcoin’s energy efficiency has long been a topic of concern within the cryptocurrency community. As mining activities continue to grow, so does the amount of electricity consumed, raising questions about the environmental impact of Bitcoin mining. Primarily, the energy consumption is attributed to the mining machines used by miners, which are notorious for their high energy requirements.
According to a recent report by Coinmetrics, three specific Bitcoin mining rig models claim a significant share of the network’s computing power. These models, namely the Antminer S19j Pro, Antminer S19 XP, and Antminer A19, collectively account for an impressive 76% of the Bitcoin network’s computing power.
Among these models, the Antminer S19j Pro and Antminer S19 have emerged as the most widely used by Bitcoin miners since 2021. Coinmetrics reveals that the Antminer S19j Pro alone contributes to 34.3% of the network’s hashrate, with the S19 following closely at 28.1%. In contrast, the Antminer S19 XP represents a smaller portion, standing at 13.7% of the network’s hashrate. Interestingly, the report mentions that the hashrate of the MicroBT M50 remained below the detectable threshold.
An Innovative Approach to Determine Machine Usage
In order to identify the machines utilized in the Bitcoin network, the researchers at Coinmetrics employed a new methodology. They tracked the fingerprints of each machine, considering factors such as electricity consumption and computing power, which vary depending on the model. This approach allowed them to gain valuable insights into the energy efficiency of different Bitcoin mining equipment.
Throughout its existence, Bitcoin has been synonymous with energy inefficiency, largely due to the high energy requirements of mining operations. Nevertheless, Coinmetrics’ report brings promising news, indicating that the Bitcoin network’s energy efficiency has significantly improved over the past five years.
The report reveals that the Bitcoin network’s energy efficiency has witnessed a remarkable improvement of approximately 60% since July 2018, thanks to the introduction of more efficient mining machines. This positive shift is highlighted by the fact that the network now consumes an average of 33.6 joules per tetrahash (J/TH) of computing power. Comparing this to the 89.3 J/TH recorded on July 1, 2018, it represents a substantial 62% increase in network energy efficiency.
Karim Helmy, one of the report’s authors, emphasizes that the rate of change in energy consumption has been more aggressive in the past. This observation suggests that the Bitcoin network is heading in the right direction when it comes to energy efficiency.
The commonly cited Cambridge University Centre of Alternative Finance’s index often serves as a reference when discussing the Bitcoin network’s energy consumption. However, Coinmetrics’ study offers an interesting revelation. Contrary to popular belief, the study found that the Bitcoin network consumes 13.4 gigawatts (GW) of power, which is 13% lower than the Cambridge index suggests. This significant difference challenges the critics who argue that Bitcoin’s energy consumption is unreasonably high.
Acknowledging the potential environmental impact of Bitcoin mining, miners are increasingly turning to sustainable and green energy alternatives. An insightful report by CoinShares indicates that a significant 74.1% of Bitcoin mining power derives from renewable energy sources. This shift towards cleaner energy demonstrates the industry’s commitment to reducing its carbon footprint and ensuring a more sustainable future.
An exciting recent development comes in the form of the Volcano Energy project, initiated by a startup based in El Salvador. The project aims to establish a 241 MW renewable energy power generation park, requiring a total investment commitment of $1 billion. Remarkably, the project has already secured an initial funding round of $250 million, with support from various investors, including Tether, the issuer of the USDT stablecoin. Tether’s involvement in the project signifies their commitment to leveraging their expertise to promote sustainable energy solutions within the Bitcoin mining ecosystem.
Bitcoin’s energy efficiency has experienced a transformative journey over the years. As mining technology advances and more efficient machines enter the market, the environmental concerns associated with Bitcoin mining are being actively addressed. The growth in renewable energy adoption and the commitment of industry players to sustainability are paving the way for a greener future for Bitcoin and the broader cryptocurrency ecosystem as a whole.
