Why is Bitcoin Bad for the Environment? Simple 2023 Guide

Why is Bitcoin Bad for the Environment

‍Bitcoin is one of the most popular cryptocurrencies in the world, but it has been criticized for its environmental impact. In this blog post, we’ll be discussing why Bitcoin is bad for the environment, as well as how it can be made more environmentally friendly in the future.

Bitcoin and its Impact on the Environment

Bitcoin is a digital currency that was created in 2009 and is used as a means of exchanging value between two parties. It is a decentralized form of currency, meaning that it is not regulated by any government or central bank. Instead, it is managed by a network of computers, known as miners, who use specialized software to process transactions and maintain the network’s security.

The problem with Bitcoin is that it requires a lot of energy to mine new coins. This energy comes from burning fossil fuels like coal and natural gas, which are both major contributors to climate change. The use of these fuels has led to an increase in greenhouse gas emissions, which have a direct effect on the environment.

Bitcoin Mining and its Environmental Impact

In order to understand why Bitcoin is bad for the environment, it’s important to understand how it is mined. Bitcoin mining is the process of using specialized computers to solve complex mathematical problems in order to verify and validate transactions on the Bitcoin network.

These computers consume a lot of energy in the form of electricity, which comes from burning fossil fuels. This process of burning fossil fuels releases carbon dioxide into the atmosphere, which is one of the major causes of climate change.

In addition to this, the mining process also requires a lot of computing power, which can lead to overheating of the computers. This means that the energy used for mining is not only wasted, but it can also have a negative impact on the environment.

The Pros and Cons of Bitcoin

While Bitcoin has some positive aspects, such as providing a secure, decentralized form of currency, it also has some negative effects on the environment. In order to understand why Bitcoin is bad for the environment, it’s important to weigh the pros and cons.

One of the major pros of Bitcoin is that it provides a secure and reliable form of currency. Transactions are encrypted and stored on the blockchain, making them virtually impossible to hack or counterfeit. This makes it a great choice for those who want to protect their money from fraud.

However, the downside is that the mining process can be extremely energy-intensive, which can lead to an increase in greenhouse gas emissions. This can have a detrimental effect on the environment, as it contributes to climate change.

What is Bitcoin’s Carbon Footprint?

The carbon footprint of Bitcoin is estimated to be around 36.95 million metric tons of CO2 per year. This is because the mining process requires a lot of energy, and most of this energy comes from burning fossil fuels.

This is a major problem, as it means that Bitcoin is contributing to climate change. As the amount of energy required for mining increases, so does the carbon footprint of Bitcoin. This is why it is important to find ways to reduce the energy consumption of Bitcoin mining.

Cryptocurrency Mining’s Environmental Impacts

Calculating cryptocurrency’s carbon impact is more difficult. Although fossil fuels are the most common source of energy in most nations where bitcoin is mined, miners must seek for the most cost-effective energy sources in order to remain profitable.

According to Digiconomist, the Bitcoin network emits approximately 73 million tons of CO2 per year, which is equivalent to Turkmenistan’s emissions.
According to data through September 2022, Ethereum created an estimated 35.4 million tons of CO2 emissions before decreasing to 0.01 million tons after switching to proof of work.

Countries with the Most Influence

According to the University of Cambridge researchers, the majority of Bitcoin mining takes place in the United States, China, and Kazakhstan. According to the Center for Strategic and International Studies, coal and crude oil account for around 76% of China’s energy consumption.

China accounts for 21% of the worldwide hash rate.

Approximately 38% of mining occurs in the United States. According to EIA data from 2019, the United States generates the majority of its electricity by burning fossil fuels.
Kazakhstan accounts for 13% of global Bitcoin mining and primarily uses fossil fuels.

As a result, three countries largely reliant on fossil fuels account for roughly 72% of global Bitcoin mining.

Electronics Waste

Cryptocurrency mining also generates a lot of electrical trash because mining hardware wears out quickly. This is especially true for ASIC miners, which are specialized equipment built to mine the most popular cryptocurrencies. The Bitcoin network generates around 38 thousand tons of electronic garbage per year, according to Digiconomist.

Could Bitcoin Mining Use Less Energy?

Large-scale bitcoin miners are frequently located in areas where energy is abundant, reliable, and inexpensive. However, bitcoin transactions and coin minting do not have to be energy-intensive.

The proof-of-stake (PoS) technique of authenticating cryptocurrency transactions and minting new coins is a low-computing-power alternative to cryptocurrency mining. Instead, the ability to validate transactions and operate the crypto network is based on the amount of bitcoin that a validator has “staked,” or pledged not to trade or sell.

Other validation methods are also being developed, such as proof of history, proof of elapsed time, proof of burn, and proof of capacity. While Ethereum’s developers have decommissioned the blockchain’s proof-of-work mechanism, with estimates claiming a 99.9% reduction in carbon emissions, the Bitcoin community has no such goal.
Because Bitcoin is the most popular cryptocurrency, mining, with its high energy costs, is almost certainly here to stay.

Is It Possible for Bitcoin to Become Environmentally Friendly?

In short, because the validation process is energy-intensive, competitive, and based on rewards, Bitcoin is unlikely to minimize its energy footprint. Even after the last bitcoin is awarded, the network will continue to demand significant amounts of electricity to validate transactions.

How Can Bitcoin Become More Environmentally Friendly?

There are a few ways that Bitcoin can become more environmentally friendly. One way is to switch from energy-intensive mining methods to renewable energy sources. This means that miners would use solar, wind, or hydropower instead of burning fossil fuels.

Another way to reduce the negative impact of Bitcoin on the environment is to switch to more energy-efficient mining hardware. This hardware is designed to use less energy, which can reduce the amount of energy needed for mining.

Finally, Bitcoin miners can also join a mining pool. This is a group of miners that share their computing power in order to reduce the energy consumption of the network. By joining a mining pool, miners can help reduce the carbon footprint of Bitcoin thereby reducing the negative impact on the environment.

How Much Cryptocurrency Is Renewable?

There is presently insufficient official data to estimate how much of the energy needed by cryptocurrency comes from renewable sources.

What are the Negative Effects of Cryptocurrency?

In addition to its environmental impact, cryptocurrency can also have some negative effects on society. One of the most common criticisms is that it can be used for illegal activities, such as money laundering or drug trafficking.

It can also be used to fund terrorist activities, as well as provide a form of payment for criminals. This has some serious implications, as it can lead to an increase in crime and corruption.

Finally, cryptocurrency can also be used to manipulate the market. This can lead to price manipulation, which can have a negative effect on investors.

What is the Biggest Problem with Cryptocurrency?

The biggest problem with cryptocurrency is its environmental impact. As mentioned above, the mining process requires a lot of energy and most of this energy comes from burning fossil fuels. This means that cryptocurrency is contributing to climate change and it is important to find ways to reduce the energy consumption of mining.

Facts About Bitcoin

#1. The value of cryptocurrencies and bitcoins has skyrocketed

In 2019, the first decentralized cryptocurrency, Bitcoin, was developed by pseudonymous developer Satoshi Nakamoto. Since its inception, the total cryptocurrency market cap has surpassed USD$3 trillion. Bitcoin’s price reached an all-time high in 2021, reaching USD$65,000 in value.

#2. Creating Bitcoin is a Difficult Process

New Bitcoins are generated through a process known as mining, which involves solving mathematical riddles. These puzzles became increasingly tough as competition for this coin increased, making them impossible to solve with standard computers (CPUs). Miners now use far more efficient computers known as ASIC systems, which demand significantly more electricity to operate. Bitcoin also employs a software code known as Proof of Work (PoW), which requires the utilization of large computer arrays to validate and protect the world’s ever-increasing number of transactions.

#3. Bitcoin Data Centers are Massive and Expensive to Maintain

Bitcoins are created in huge computer centers, which are referred to as’mining farms’. They are made up of thousands of ASIC servers that range in price from a few hundred dollars to around USD$10,000. Because they are constantly mining for Bitcoins, these servers are often kept running indefinitely. Massive cooling systems are required in mining farms to keep servers from overheating. However, this considerably raises the electrical costs associated with operating these enormous data centers.

#4. Bitcoin mining necessitates massive amounts of electricity.

Bitcoins need enormous quantities of energy. Each transaction requires approximately 2,100 kilowatt-hours, which is equal to what the average US household consumes in two months.

Furthermore, Bitcoin mining consumes 91 terawatt-hours of electricity each year, which is approximately seven times the amount required to power Google searches worldwide and accounts for about 0.5% of global electricity use. Finland, Sweden, the Netherlands, and Greece use nearly the same amount of energy in a year. Furthermore, crypto mining threatens some countries’ frail electricity infrastructures, which struggle to handle the power-intensive process. Several cities in Iran, Kazakhstan, and Kosovo have frequently experienced protracted blackouts as a result of Bitcoin mining activities.

#7. Bitcoin Has a Negative Impact on the Environment

According to calculations, Bitcoin emits approximately 57 million tons of CO2 each year, or nearly half a ton of CO2 for each transaction. Planting 300 million trees would be required to offset such massive emissions. Furthermore, according to a 2018 study published in Nature Global Change, the use of Bitcoin alone might push the world past the 2-degree Celsius warming threshold for climate catastrophe in 16 to 22 years.

Some countries have prohibited the use of Bitcoin or other cryptocurrencies. Altogether
Cryptocurrencies are now prohibited in nine countries: Algeria, Bangladesh, China, Egypt, Iraq, Morocco, Nepal, Qatar, and Tunisia. While several countries used environmental reasons to justify their decisions, many people believe that these actions are being taken to safeguard their banking systems. Following China’s Bitcoin ban, several operations relocated to the United States. Kentucky is by far the state that creates the most carbon from cryptocurrency mining, accounting for 18.7% of Bitcoin’s collective processing power, trailing just New York’s 19.9%.

#8. Most Bitcoin Farms in the World Count on Fossil Fuels

Environmentalists are concerned since bitcoin farms are frequently located in nations that rely significantly on fossil fuels, such as Kazakhstan, Iran, and Kosovo. The already energy-intensive process has an even greater environmental impact in this country than in countries that diversify their energy sources by employing renewables or even nuclear energy. Bitcoin miners in the United States frequently rehabilitate toxic coal plants on the point of bankruptcy, accounting for a massive increase in emissions and risking a partial revival of coal in the country. Others use fracked gas, another kind of energy that contributes to global warming.

Do We Have Bitcoin Alternatives, and Are They Any Better?

The quick answer is yes. There are plenty of superior alternatives to the world’s most popular cryptocurrency. Other cryptocurrencies consume 99% less electricity than Bitcoin on average. According to Greenpeace’s latest campaign, ‘Tweak the Code, Not the Climate,’ a simple change in Bitcoin’s software code may drastically reduce the energy required to create and utilize the currency. It would not be the first time this happened: one of Bitcoin’s key competitors, Ethereum, recently announced its shift to a less energy-intensive code, reducing its electricity usage by 99.9% and substantially reducing its environmental impact.

Is Bitcoin a Blessing or a Curse?

Whether Bitcoin is a blessing or a curse ultimately depends on how it is used. On the one hand, it provides a secure and reliable form of currency, which is great for those who need to protect their money from fraud. On the other hand, its environmental impact is concerning and there are some serious implications that come with using cryptocurrency.

Ultimately, it is up to individuals to decide if Bitcoin is a blessing or a curse. It is important to weigh the pros and cons and decide if the benefits of using Bitcoin outweigh the potential negative effects.


In conclusion, Bitcoin has both positive and negative effects on the environment. Its decentralized nature makes it a secure form of currency, but its energy-intensive mining process contributes to climate change.

In order to reduce the environmental impact of Bitcoin, it is important to switch to renewable energy sources and more energy-efficient mining hardware. It is also important to join a mining pool in order to reduce the energy consumption of the network.

Finally, it is up to individuals to decide if Bitcoin is a blessing or a curse. It is important to weigh the pros and cons and decide if the benefits of using Bitcoin outweigh the potential negative effects.
