The environmental impact of cryptocurrency is a critical issue as the market is expanding globally. While cryptocurrencies are an essential technology that provides decentralized financial systems, their energy consumption and ecological footprint raise concerns.
How Does Cryptocurrency Affect the Environment?
Cryptocurrencies are built on blockchain technology. A decentralized ledger system that uses a consensus mechanism to store and record transactions across multiple computers. Cryptocurrencies like Bitcoin use “Proof-of-work” for transaction validation, where miners solve complex mathematical problems to add new blocks to the blockchain. The entire process requires high computational power and energy.
Bitcoin is the most valuable cryptocurrency; it is famous for its massive power consumption. According to recent estimates, Bitcoin consumes more electricity annually compared to some small countries like Argentina or the Netherlands.
The demand for power results in increased carbon emissions every year, which directly impacts global climate change. Digiconomist estimates that the bitcoin network is responsible for 55 million tons of carbon dioxide emissions per year, which is equal to the amount generated by Singapore. Ethereum produced a total of 35.4 million tons of carbon dioxide emissions before dropping its amount, influenced by its transition to proof of stake. The carbon emission is a real issue considering metrics that state Bitcoin and Ethereum alone contribute millions of CO2 annually, which is equivalent to millions of cars on the road. It is a critical problem that reflects on the already Worse environmental issues like global warming and air pollution.
Environmental Impact of Crypto Mining
Crypto mining is a very energy-consuming and tedious process where miners do different tasks to add new tokens to their respective blockchains. Beyond energy consumption, cryptocurrency mining also generates tons of electronic waste every year. Mining rigs and computers have a limited lifespan as they run day and night at high processing power to complete the process of mining the coin. Disposing of such electronic waste improperly can plant the seed for the destruction of natural resources.
There are many instances where cryptomining has affected the economy in several regions. For instance, excessive water use for cooling mining equipment and noise pollution affect the wildlife and communities living nearby. As of May 2021, bitcoin mining is estimated to generate 30.7 metric kilotons of e-waste annually.
Emerging Solutions and Sustainable Practices
The crypto community, along with the environmental advocates, is constantly finding sustainable solutions to the challenges regarding e-waste and high energy consumption.
- Ethereum is a popular cryptocurrency that recently transitioned from proof of work to proof of stake and thereby drastically reduced the amount of energy consumption by up to 99%. PoS algorithms can maintain blockchain security with minimal computational costs, giving a solid solution for future cryptocurrencies.
- Crypto mining using renewable energy resources like solar, wind, and hydro power sources can help reduce the carbon footprint and present a green mining architecture.
- Governments have begun to regulate cryptocurrency mining activities through energy consumption reporting and carbon pricing. This growing concern has driven the crypto community towards projects that prioritize sustainability. This shift has also encouraged developers and investors to pursue more eco-friendly solutions.
BItcoin Environmental Impact vs banking
| Feature | Bitcoin | Traditional banking systems |
|---|---|---|
| Energy consumption mechanism | Works on the Proof of Work consensus mechanism. Where powerful computers compete to mine new coins. | Has a massive global infrastructure, including bank branches, ATMs, data centers, etc. |
| Annual energy consumption | Estimates depend on the time frame and methodology, but some analysts say 113 TWh per year is the total electricity usage. | Banking has a massive network and complexity; a comprehensive and standardized figure is difficult to calculate, but some analysts predict that traditional banking uses more energy overall than the Bitcoin network. |
| Environmental footprint | Concerns mainly regarding the high energy usage of PoW mining and associated carbon emissions. Millions of metric tons of carbon emissions annually. | Requires energy for the construction of buildings, fuel for vehicles transporting cash, and resource consumption for printing money and making coins. And the energy required for the global IT infrastructure. |
| Source of energy | Mainly utilize fossil fuels, particularly in regions with cheaper, carbon-intensive electricity. | Mixed sources, including fossil fuels, renewable energy sources like solar for branches and data centers. |
| Transparency | The initiative, like the Cambridge Bitcoin Electricity Consumption Index (CBECI), tracks this data. Hence, it is relatively transparent and easy to track the energy consumption and carbon emissions. | There is no single point of data collection. Its energy usage is fragmented across the countless institutions and activities, making a transparent tracking mechanism impossible |
| Potential improvements | Some cryptocurrencies have moved to less energy-consuming models, such as Proof of Stake, to drastically reduce the energy consumption | The banking industry can focus on improving its digital footprint by investing in renewable energy to conduct its operations. |
Final Thoughts – Environmental Impact of Crypto Mining
Cryptocurrencies like Bitcoin require large amounts of energy, and they create electronic waste every year. Bitcoin and other cryptocurrencies bring financial systems to millions of people around the world who don’t have access to loans, banking, or other financial services. Some believe that cryptocurrencies have no value as they don’t have any tangible property, some have doubts that crypto is only for those who can afford expensive mining equipment and high market values, notably businesses and the already wealthy.
To summarize, cryptocurrency has an environmental impact. The system is designed in such a way that the energy and equipment required to run its system take a high toll on the planet’s ecosystem. It consumes fossil fuels and generates a million metric tons of CO2 each year.
