One potential rephrasing: The environmental impact of cryptocurrencies has been a significant issue for investors and observers for some time. But can we create a “green” crypto that minimizes its ecological footprint?
An eco-friendly type of cryptocurrency, often referred to as green crypto, is creating quite a stir in the realm of blockchain technology. The reason for this buzz is primarily because Bitcoin (BTC), the most well-known cryptocurrency, uses an enormous amount of electricity – around 150 terawatt-hours. To put that into perspective, Argentina, a country with over 45 million inhabitants, consumes less electricity than Bitcoin does.
In a 2022 study published by Sciencedirect, it was found that the carbon footprint of the electricity used by the Bitcoin network grew from approximately 478.27 grams of CO2 per kilowatt-hour (kWh) in 2020 to around 557.76 grams of CO2 per kWh in August 2021. Ethereum‘s energy consumption is not far behind.
Considering these worries, it’s a common query: Can the crypto industry shift towards a more environmentally friendly and sustainable future?

What is green crypto?
Green crypto refers to the category of cryptocurrency projects that focus on sustainability and lessen the environmental footprint of blockchain technology, specifically targeting the energy-intensive proof-of-work (PoW) consensus mechanisms used by Bitcoin and Ethereum.
Supporters of eco-friendly cryptocurrencies propose the adoption of less power-hungry consensus methods like proof-of-stake (PoS) and proof-of-authority (PoA). Instead of relying on miners to solve intricate mathematical problems that consume vast amounts of energy, these mechanisms depend on validators or stakeholders. Consequently, they result in lower energy consumption.
An extra approach for eco-friendly cryptocurrency projects is to advocate for the use of renewable energy in mining processes, adopt energy conservation methods within blockchain systems, and compensate for the carbon footprint caused by crypto mining.
Promising green crypto projects: most energy efficient cryptocurrency
Reaching carbon neutrality in the crypto world is a realistic goal that some mining and cryptocurrency companies have already accomplished in more recent times.
In 2022, a hydropower plant located in Costa Rica gained attention for providing carbon-neutral cryptocurrency mining services. This plant powers approximately 650 computers, which mine cryptocurrencies for around 150 customers. It started offering these services during the COVID-19 pandemic and relies solely on clean energy.
Bitfarm, a Bitcoin mining company, asserted that at least 99% of the electricity they consume for cryptocurrency mining comes from renewable sources. According to their website, they utilize a total of 158 megawatts of clean energy. Similarly, Neptune, another digital asset platform, promotes its eco-friendliness by emphasizing its commitment to harnessing renewable energy such as solar, hydro, and wind for powering their Bitcoin mining activities.
The cryptocurrency ADA, which is native to the Cardano platform, is known for its eco-friendliness. This is because Cardano operates on a proof-of-stake (PoS) consensus mechanism, which is more energy efficient than other methods. In fact, Cardano processes around 1,000 transactions each second while using relatively low amounts of energy. According to studies, the entire Cardano network requires only 6 gigawatt-hours of power annually, making it a rather energy-efficient blockchain solution.
Ripple (XRP) is another digital currency that prioritizes the environment, boasting an average energy consumption per transaction of just 0.0079 kilowatt-hours. According to certain visual representations, XRP‘s power usage trails behind Bitcoin, Ether, and Visa. With a processing speed of 1,500 transactions per second, XRP significantly minimizes its carbon footprint.
Investing in green cryptocurrencies
In essence, investing in eco-friendly cryptocurrencies follows a comparable path to investing in regular cryptocurrencies. To get started, potential investors should conduct thorough research on green cryptos and related initiatives that match their environmental concerns. A valuable strategy could be to acquire a solid foundation of knowledge regarding the technological basis of more sustainable crypto solutions.
It’s important for investors to check if their preferred crypto exchange offers trading in eco-friendly digital currencies before transferring funds. After funding their account, they can then purchase the sustainable cryptocurrencies that align with their investment objectives.
Once you’ve bought some eco-friendly cryptocurrencies, it’s a good idea to move them into a safe digital wallet for safekeeping.
When considering investing in cryptocurrencies, keep in mind that they come with inherent risks. These risks include price fluctuations and regulatory uncertainty. Even if a specific cryptocurrency aligns with your sustainability values, it’s crucial to consider other factors such as your market knowledge, risk tolerance, and portfolio diversity before making a decision. As for the question at hand, the title “Can crypto go green?” implies a focus on the environmental impact of cryptocurrencies. However, the body of the text discusses risks related to investment, so it might be clearer to ask, “What are the sustainability considerations and risks when investing in cryptocurrencies?” instead.
The future of green crypto
In the coming years, numerous companies, with a particular focus on the mining sector, are working diligently to minimize cryptocurrency’s carbon footprint. What are some ways the broader crypto community could eventually go green?
Changing the consensus algorithms
Above it has been explained that Proof of Work (PoW) involves miners carrying out intricate computations to generate new coins, which consume substantial energy and have a large carbon footprint due to the power-hungry nature of these cryptographic calculations. Even advanced machinery like application-specific integrated circuits (ASICs), designed to enhance energy efficiency in mining processes, require vast amounts of electricity.
On the other hand, newer cryptocurrencies are adopting advanced and less energy-consuming methods for validation. Proof of Stake (PoS) is a common choice, as it requires minimal power usage for block creation and rewards are based on the amount of stake held by network participants.
Proof of Stake (PoS) has been improving with advanced versions such as Delegated PoS, Nominated PoS, and Mutualized PoS. Networks including Cardano, Polygon (MATIC), and Polkadot (DOT) employ different forms of PoS consensus. In September 2022, Ethereum underwent an update called the Ethereum Merge, transitioning from a Proof of Work (PoW) to a Proof of Stake (PoS) system. This shift was anticipated to significantly decrease Ethereum’s energy consumption by approximately 99%.
Alternative energy sources
An eco-friendly alternative for cryptocurrencies is harnessing renewable energy from sources like sunlight, wind, and water currents instead of relying on traditional power sources.
SolarCoin rewards solar energy production with 1 coin for every megawatt hour generated. Powerledger is a platform that enables direct energy trading between individuals.
Just like the previously mentioned Costa Rican plant, Genesis Mining is a cloud mining service based in Iceland that runs its mining operations using only renewable energy.
Conclusion
Putting money into eco-friendly cryptocurrencies allows you to combine your financial ambitions with a commitment to the environment. With increasing worldwide emphasis on sustainability, there’s a strong likelihood that interest in eco-friendly crypto projects will surge, possibly leading to profitable investment possibilities.
Yet, it’s important to exercise caution when investing in cryptocurrencies. Consider if the investment aligns with your financial situation and environmental values. Also, be mindful not to risk more funds than you’re prepared to potentially lose.
