Cryptocurrency is a digital currency that can be used to purchase goods and services, but uses an online ledger with strong cryptography to secure transactions. Cryptocurrencies work within a so-called “Blockchain‘, which is essentially a huge database of information that cannot be changed or manipulated.
There are many, many different cryptocurrencies including Dogecoin, Ripple, Ethereum, etc., but Bitcoin is the largest. It was the first decentralized cryptocurrency launched in 2009. Bitcoin has inspired hundreds of imitators but remains the largest cryptocurrency by market capitalization, a distinction it has held throughout its more than decade-long history.

Public blockchains like Bitcoin are extremely transparent. The nature of blockchain technology means that all data is immutable, traceable and permanent, meaning anyone can see the balance and transactions of any wallet address. No one, not the government, not even advanced hackers, can question, change or delete what you own on the blockchain.
When you purchase any type of cryptocurrency, store it in a digital wallet that uses advanced encryption rather than a standard bank account.
In the world of cryptocurrency, “mining” is performed by complex, high-performance computers. Bitcoin Miners operate complex computing facilities to solve complicated mathematical puzzles, called proof-of-work (PoW), to confirm groups of transactions called blocks; If successful, these blocks are added to the blockchain record and miners are rewarded with a small number of Bitcoins. Other participants in the Bitcoin market can buy or sell tokens through cryptocurrency exchanges or peer-to-peer.
Bitcoin is booming and its price exceeded $60,000 in October 2021, but is considered the least efficient due to its uncontrollable need for computer hardware and energy.
Below are some reasons why Bitcoin is bad for the environment.
Consumes an enormous amount of energy
To quote Elon Musk: “The energy consumption trend of the last few months in cryptocurrencies is crazy.” Musk was referring to the amount of energy required to “mine” Bitcoin. Mining is done by powerful computers that compete to solve complex mathematical puzzles in an energy-intensive process. In most cases, this process is often based on fossil fuels, particularly coal. To put things into perspective, analysts at Deutsche Bank estimated that if Bitcoin were a country, it would use about the same amount of electricity per year as Ukraine.
As of March 2021, Bitcoin’s electrical footprint was just over 75% of the Netherlands’ total energy production and about 9% of Russia’s. Similarly, various other researchers claim how devastating the virtual coin is to the environment. A Bitcoin transaction reportedly consumes 1,544 kWh of energy, which is the same amount of power an average can hold US Budget has been running for 53 days.
Bitcoin’s energy consumption figures are very worrying as the numbers are increasing rapidly.
Produces more electronic waste
Due to the high energy consumption, a large amount of electronic waste (electronic waste) is generated when mining the virtual currency. E-waste is a leading cause of water and soil pollution as discarded electronic devices, toxic chemicals and metals are deposited in water and soil.
Due to the limited availability of resources used in the production of chips such as silicon and quartz, e-waste becomes problematic. Additionally, since the lifespan of the devices that Bitcoin miners use is only about 18 months, a lot of hardware is quickly consumed and ultimately ends up in e-waste. The researchers claim that the e-waste produced by Bitcoin per year (24 kilotons) is the same as the e-waste produced in an entire country (Netherlands).
Larger carbon footprint

Bitcoin mining uses enormous amounts of energy, resulting in a larger carbon footprint every year. As Bitcoin’s value increases, so does its mining, meaning the puzzles become more complex and companies invest in computing power.
Since only a limited amount of Bitcoin can be produced each day, miners compete online in PoW mining, making the puzzle more difficult and production slower, making them extremely energy inefficient.
In research, the numbers were shocking, with the carbon footprint of a single virtual coin equivalent to that of 1,879,709 Visa transactions.
Lower consumption of renewable energy
Bitcoin has long been criticized for its negative impact on the environment. Proponents still say that switching to renewable energy would reduce carbon emissions, but the truth is that Bitcoin still uses massive amounts of energy.
According to reports, only 39% of PoW mining of virtual coins is carried out using renewable resources. Miners are still moving to different parts of the world where fossil fuels are still used on a large scale. Many private companies are buying decommissioned coal-fired power plants and turning them into a power plant-cryptocurrency mining hybrid. Environmentalists fear that waste coal left over from coal mining can release harmful chemicals into surrounding soil and water sources. And combustion still produces carbon dioxide.
A Columbia Business School researcher quoted: “There is a new generation of cryptocurrencies coming to market that will move away from Proof of Work (PoW) for several reasons, one of which is the environmental impact, as most of them are. “created by young programmers. They are certainly more environmentally conscious and hope to understand the impact of the work beyond what they are building and consider the complexities of today’s world.”
Cryptocurrencies need to be more sustainable. They cannot ignore environmental considerations if they want to achieve wider adoption, keeping in mind that newer and greener cryptocurrencies will eventually eclipse Bitcoin.
