In recent times, the concerns raised by Elon Musk, a former supporter of cryptocurrencies, about the environmental cost of Bitcoin, have created quite a stir among crypto enthusiasts.
Elon Musk Twitter the following on Twitter,
He Says, "Cryptocurrency is a good idea on many levels.We believe it has a promising future but this cannot come at great cost to the environment."
Musk's statement has triggered a debate across the internet over Bitcoin's environmental effect and its possible ramifications for the future of the crypto tech revolution.In this post, we will look into the energy usage of Bitcoin mining to better comprehend its influence on our world.
But How Exactly does Bitcoin Contribute to Carbon Emissions?
After reading this, you guys may wonder how a digital currency such as Bitcoin can even have a carbon footprint, right?. Isn't it just "fake internet money"? However, the environmental impact of traditional tender, such as banknotes made from deforestation or coins minted from extracted gold, may intuitively seem worse. To unravel this conundrum, let's examine the fundamental problem that Bitcoin aims to solve.
All digital currencies face the challenge of the "double spending problem" during their development. For example,if I wanted to buy a car using digital currency, the car salesman of the car would have no way of knowing if the same currency is simultaneously being used to purchase a boat or something else. If both transactions are somehow legitimized by any means, I could walk away with both the car and the boat, leaving the sellers in the dark.
With conventional credit cards, all transactions are centrally logged and verified, preventing the same money from being spent twice. However, Bitcoin takes a different approach as it is said to be decentralized. The Creator of Bitcoin, Satoshi Nakamoto introduced the revolutionary concept of Blockchain, which is the cornerstone of Bitcoins value.
The blockchain operates through network computers worldwide racing to verify the legitimacy of recent Bitcoin transactions by solving complex mathematical puzzles known as "hashing". A machine is paid with Bitcoins when it correctly validates a block of transactions. This procedure generates a validated record of transactions, which forms a part of the decentralised Blockchain.
No individual can tamper with the blockchain directly, ensuring its reliability. In the case of our example, the first verified transaction, either the car or the boat, wins, while the other is automatically rejected. The computer that successfully verifies the block is rewarded with bitcoins. This confirmation mechanism, called "proof of work," maintains the integrity of the Blockchain very effectively. But the main problem is that it also consumes a significant amount of computing power in the process.
The Energy Consumption Challenge
To maximize their chances of solving the complex hash and earning bitcoins, miners need to operate numerous computers, often in large server farms. The more computers running, the higher the statistical likelihood of success. Although the energy bills associated with mining are substantial, they are outweighed by the rising value of Bitcoin.
Larger mining farms operate thousands of computers, each one burning energy in an attempt to solve the hash. This process consumes an enormous amount of computing power, which clearly leads to a significant carbon footprint. In fact,Data says that Bitcoin mining currently consumes approximately 129 terrawatt hours of Electricity per year in the world which surpassed the energy consumption of major tech organizations like Google, Microsoft, Amazon Etc.
As Bitcoin's popularity grows, so does its carbon impact. Bitcoin mining has raised emissions by nearly 40 million tonnes in the last two years alone, comparable to the emissions of 8.9 million vehicles. Bitcoin now emits more carbon than American Airlines and is fast approaching the carbon footprint of the entire Federal US government.
The Concerns Raised by Elon Musk
Elon Musk's recent intervention regarding Bitcoin's environmental impact further amplified the debate. Tesla, a company known for its commitment to sustainability, suspended vehicle purchases using Bitcoin due to concerns about the increasing use of fossil fuels for mining and transactions. Musk specifically pointed out the reliance on coal, which has the highest emissions among all fuels.
Critics have raised questions about the inconsistency of Tesla's decision. In 2020, the company received $1.5 billion in environmental subsidies funded by taxpayers, only to invest the same amount in Bitcoin, a currency primarily mined using electricity generated from coal. According to observers, such subsidies should be scrutinised more rigorously. While the IT sector has made some steps to address the environmental challenges related with cryptocurrencies, there is still much more that needs to be done.
Alternatives and Potential Solutions
Not all cryptocurrencies have the same environmental impact as Bitcoin. For example, Cardano, a rival to Bitcoin, uses a "proof of stake" consensus instead of "proof of work." Miners in the Cardano network stake their own coins as collateral while validating transactions and receive rewards accordingly. This approach significantly reduces energy consumption, with Cardano mining requiring as little as 6 gwh.
Another cryptocurrency, Chia, employs a unique "proof of space" validation system. Users offer empty space on their hard drives to the network, which requires less energy compared to traditional mining. However, Chia's popularity has led to physical shortages of hard drives in some regions.
While Bitcoin is frequently chastised for its environmental effect, other cryptocurrencies, such as Ethereum, also contribute to carbon emissions. Ethereum's carbon footprint is as significant as that of Hong Kong. Bitcoin proponents argue that the conventional banking system is even more environmentally damaging, consuming over 260 terrawatt hours. However, considering the large user base of conventional banking compared to the limited number of Bitcoin users, such comparisons become less relevant.
The Future of Bitcoin and Environmental Sustainability
We hope that Bitcoin will eventually recognize the need for change and adopt alternative approaches that reduce the environmental impact by mining process. Renewable energy sources could also play a crucial role in tackling with the carbon emissions associated with the mining. Although, these solutions require honest efforts and commitment to sustainability.
While the energy consumption of Bitcoin mining is undeniably substantial, it is important to prioritize the challenges and address them one by one. Elon Musks intervention has worked as a fuel to the discussion, which obviously raise questions about potential market manipulation like such.

In Conclusion
Bitcoin mining's energy consumption has raised concerns about its environmental impact. The carbon footprint associated with mining has grown significantly, leading to emissions comparable to those of major industries. Elon Musk's recent remarks regarding Bitcoin's environmental cost have intensified the debate, calling for alternative approaches and greater sustainability. While other cryptocurrencies offer more energy-efficient solutions, Bitcoin's dominance necessitates a closer examination of its environmental practices. By exploring renewable energy sources and adopting innovative consensus mechanisms, the crypto industry can strive for a greener future.
