Crypto Sustainability: How to Choose Eco-Friendly Cryptocurrencies

The idea of a digital currency that can be transferred anywhere in the world instantly and without any fees has changed the way we do business. It’s also created some major environmental problems. The rise of crypto has been accompanied by an increase in power consumption and waste and a growing problem with e-waste.

Crypto sustainability is an issue that needs to be addressed if we’re going to continue using cryptocurrencies. That’s why we’ve created this guide—to help you find eco-friendly cryptocurrencies that are truly sustainable and will help keep our planet healthy for future generations.

The Problem With Proof-Of-Work

In the world of cryptocurrency, “proof of work” is a system that is used to verify the validity of a transaction. It was invented by Adam Back in 1997 and it has become one of the most popular methods for securing blockchains.

However, proof-of-work mining has some serious drawbacks when it comes to sustainability:

  • It uses an incredible amount of electricity—more than 3% of all electricity worldwide!
  • It also produces toxic waste (and even kills animals). For example, Bitcoin mining uses more energy than 159 countries put together!


Proof-of-Stake (PoS) is an alternative to Proof-of-Work (PoW). PoS is a consensus mechanism that allows for the validation of transactions on a blockchain with no mining required. In simple terms, it means that users who own more cryptocurrency are rewarded more when they validate transactions. This method of validating transactions can be much more energy-efficient than PoW because there’s no need to expend any additional energy on the verification process.

It’s important to note that while this may sound like a great idea, in theory, it has some drawbacks as well. One is that larger holders would control which blocks get added to the chain instead of miners who work harder to solve difficult mathematical problems. Another is that larger holders have an incentive to maintain their stake and increase their value by selling off coins slowly over time due to inflation. 

Thirdly, suppose someone was able to gain a 51% majority of all stakes through large amounts of money invested. In that case, they could potentially double-spend the currency or steal funds from others without anyone being able to stop them. That’s because proof-of-stake doesn’t require any sort of computational power like proof-of-work does. So long story short, if you want maximum decentralization, then stay away from proof-of knowledge systems!

Green Crypto Mining

Some crypto miners are now using renewable energy sources to mine cryptocurrencies. This is called green mining, and it involves using a combination of solar power, hydroelectricity, and wind energy to mine cryptocurrency without producing carbon emissions or consuming non-renewable resources.

Green mining is not always possible for everyone, but it makes sense to use it as much as possible if you have access to clean energy. In some cases, this type of mining can also be more cost-effective than traditional mining methods because you won’t need expensive electrical equipment, and you don’t have to pay for any additional electricity costs associated with running your computer 24/7 at full capacity in order to generate revenue from your investment portfolio by mining altcoins like Ethereum Classic.

Crypto Sustainability at the Industry Level

Crypto sustainability at the industry level is another solution. As consumers and investors it’s up to us to demand sustainable cryptocurrencies from exchanges and wallets.

As the crypto industry grows fast, sustainability is one of the most important things to watch for. The industry is still in its infancy, which means that there’s a lot of room for improvement. This can be especially important if you’re looking for an investment opportunity that will pay off in the long term—you want to make sure that your money isn’t going towards something unsustainable.

There are many different kinds of crypto, and it’s hard to know which ones are more sustainable than others without doing some research first (which we hope this guide has helped with)! Thankfully though, many cryptocurrencies have community-driven initiatives that encourage users to take care of their coins and other components like mining rigs or wallets made out of sustainable materials like bamboo or recycled cardboard boxes rather than plastic bottles!

Top Green Cryptocurrencies

When looking at a cryptocurrency, the first thing to consider is its energy consumption. This is important because the more energy a coin consumes, the more money it costs to run and maintain, which can reduce its value in the long term.

The second thing is how much energy each transaction uses. The more transactions that happen on a network, the more electricity it needs to keep running smoothly. This can be particularly problematic for smaller coins or networks with less activity than others—they may need to pay higher fees in order to ensure that miners will continue mining their coins (and not switch over to another currency).

Energy per transaction: If you want an environmentally-friendly crypto investment option but don’t have time for research or don’t feel confident enough in your knowledge of blockchain technology yet, look for cryptocurrencies that have low energy consumption per transaction but high numbers of daily transactions (or vice versa). This combination will help keep both costs down while still allowing you access.


Ripple is a cryptocurrency that uses a slightly different consensus mechanism than Bitcoin. While Bitcoin works by having miners compete to solve mathematical puzzles, Ripple uses the process of “signing” transactions to confirm ownership. This means that miners in the Ripple network don’t have to use as much energy or hardware as their counterparts in Bitcoin, which makes it a more energy-efficient cryptocurrency.

Ripple is, therefore, potentially better for the environment than its most popular alternatives if you want your crypto investment to be sustainable. That said, there are other cryptocurrencies out there using even less energy and making even smaller carbon footprints — so if you’re looking for an environmental benefit from your crypto investments, it’s worth doing further research into what’s out there!


NEM is a peer-to-peer crypto platform that was designed to be used by both individuals and businesses. It uses a system called mosaic, which allows users to create custom tokens and use them on the NEM blockchain. NEM also provides an integrated decentralized exchange, which can be used by anyone who wants to buy or sell cryptocurrencies in a safe and secure manner.

NEM is one of the most eco-friendly coins available today because it uses proof of importance (POI) as its consensus algorithm instead of proof of work (PoW). POI is similar to PoS but requires more collateral in order for someone to become eligible for minting coins through mining or staking. This makes it less energy-intensive than other consensus algorithms because less processing power is needed for each transaction in order for it to go through successfully.


IOTA is a scalable, decentralized, feeless, and modular DLT. It’s a zero-fee transaction protocol for the Internet of Things (IoT), data integrity, micro-/nano payments, and other cases where transactions are not made by humans but by machines.

IOTA is environmentally friendly in that it does not use an energy-hungry proof of work mechanism. Instead, the network uses a consensus algorithm called Tangle, which requires you to actively participate in the network instead of being paid to do so (as is common with Bitcoin). 

This means that you can’t just buy your way into IOTA with computing power and electricity bills as high as they are now. You actually have to be doing something useful instead! This means that if your machine isn’t contributing anything meaningful or beneficial to society or anyone else on this planet, then it will simply be unable to participate in IOTA at all!

This makes it one of the most environmentally friendly cryptocurrencies out there right now because there are no additional costs associated with running nodes – aside from some hosting fees if your node needs remote storage space, etc.


Reddcoin is a cryptocurrency that is designed to make tipping on social networks as easy as possible. It also aims to be used as a payment method for social media platforms. The developers behind Reddcoin feel that it will become the most widely used cryptocurrency in this space because of its ease of use, low fees, and stable price.

Reddcoin was launched in 2014 and was meant to be used as a tipping currency on Reddit, one of the largest social networking sites on the internet. Because of this history, many people still use Reddcoin today—but unlike other cryptocurrencies like Bitcoin or Ethereum, it has not gained much popularity outside of its niche market (social media).

Cryptocurrencies are having a major impact on the environment. Proof-of-stake helps, but choose your cryptos carefully.
