Cryptocurrencies have become an increasingly popular form of investment in recent years, but there is growing concern about the environmental impact of the industry. Many people are worried that the energy required to mine and trade cryptocurrencies is contributing to climate change. However, not all cryptocurrencies are created equal, and some are much more energy-efficient than others. In this article, we’ll take a look at the most environmentally-friendly cryptocurrencies on the market.

Do Cryptocurrencies Use a Lot of Energy?
Yes, cryptocurrencies use significant amounts of energy. The process of mining cryptocurrency involves solving complex mathematical equations that require a large amount of computational power to support computers and cooling systems. As the difficulty of mining increases and more miners enter the market, the energy consumption of the cryptocurrency network also grows. This has led to concerns about the environmental impact of cryptocurrencies and their contribution to climate change.
Why Is Crypto Bad for the Environment?
The main environmental concern associated with cryptocurrencies is the high energy consumption necessary for mining and trading. The vast majority of cryptocurrencies use a proof-of-work (PoW) consensus mechanism, which requires powerful computers to solve complex mathematical equations in order to validate transactions and mine new coins. This process uses a huge amount of electricity, much of which comes from non-renewable sources like coal and gas.
According to the Cambridge Bitcoin Electricity Consumption Index, Bitcoin alone currently consumes 127 TWh of electricity per year. That’s roughly the equivalent of the energy consumed by the entire country of Norway.
Why Are NFTs Bad for the Environment?
Non-fungible tokens (NFTs) are a type of digital asset that applies blockchain technology to verify ownership and authenticity. Just like with other types of cryptocurrencies, it takes a serious amount of energy to produce and trade NFTs. However, the environmental impact of NFTs is often compounded by the fact that they are frequently associated with high-value, high-transaction-volume industries like art and music, which means that their energy consumption can be particularly high.
Why Is Bitcoin So Bad for the Environment?
While Bitcoin is the most well-known and widely-used cryptocurrency, it is also one of the least energy-efficient. As mentioned earlier, Bitcoin currently consumes over 125 TWh of electricity per year, thus exceeding the consumption levels of many small countries. This is because Bitcoin uses a notoriously energy-intensive PoW consensus mechanism. The fossil fuels consumption associated with Bitcoin has been widely criticized by environmentalists and has led to calls for more energy-efficient alternatives.
Is DOGE Energy Efficient?
Dogecoin is another popular cryptocurrency that has been in the news recently. While it is not as energy-intensive as Bitcoin, it still requires a substantial amount of electricity for mining and trading. Like Bitcoin, Dogecoin uses a PoW consensus mechanism, which means that it consumes more energy than some of the newer, more energy-efficient cryptocurrencies. Dogecoin presently ranks far from the most energy-efficient cryptocurrency, with an estimated 0.12 kWh of energy used in each transaction.
Overall, the energy usage associated with cryptocurrencies and their related technologies is a major environmental concern that must be addressed to mitigate their impact on the planet.
What Are the Most Environmentally Friendly Cryptocurrencies?
There are many cryptocurrencies on the market, but not all of them are environmentally friendly. Below, we’ll explore some of the most energy-efficient cryptocurrencies available.
Chia (XCH)
Chia is a low-energy cryptocurrency that uses a new consensus algorithm called proof-of-space and time (PoST). This algorithm consumes way less energy than PoW and PoS algorithms. Chia’s unique approach to mining requires the use of hard drive space rather than high-end GPUs to maintain the decentralized network. It drastically lowers the cost of energy per transaction to just 0.023 kilowatt-hours (kWh), solidifying Chia’s position as a low-energy cryptocurrency choice.
IOTA (MIOTA)
IOTA is a cryptocurrency that applies a unique consensus algorithm called Tangle. It is a DAG (Directed Acyclic Graph) that doesn’t require miners, making it energy-efficient. Transactions on IOTA’s Tangle network are free and can be processed quickly without any fees.

It uses smart contracts to track the production and transfer of energy from one node to another, letting households buy and sell renewable energy at lower rates than traditional energy companies.
Hedera (HBAR)
Hedera (HBAR) is a carbon-negative public distributed ledger technology platform. It offers fast, secure, and fair services for businesses of all sizes to use in their digital assets and applications.
Using just 0.001 kWh per transaction, as opposed to 250 kWh for Bitcoin (Digiconomist estimates it to use 950 kWh), 55 kWh for Ethereum, and 0.003 kWh for Visa, the Hedera Hashgraph platform is 250,000 times more energy efficient than Bitcoin, according to the green website LeafScore. HBAR is considered the most energy-efficient crypto.
SolarCoin (SLR)
SolarCoin is a relatively new cryptocurrency that was created specifically to incentivize the adoption of solar power. The project rewards solar energy generation contributors with SolarCoins, which can be traded on cryptocurrency exchanges. Unlike many other cryptocurrencies, SolarCoin uses a proof-of-stake (PoS) consensus mechanism, which requires much less energy than PoW. This makes it one of the most energy-efficient cryptos available.
BitGreen (BITG)
BitGreen is another PoS-based cryptocurrency that aims to promote sustainable practices. The project encourages users to engage in environmentally-friendly activities like recycling and reducing their carbon footprint and rewards them with BitGreen coins. BitGreen also uses a unique “mint-and-burn” mechanism to control the supply of coins, which helps to lessen inflation and maintain price stability.
How Does a Cryptocurrency Become Energy Efficient?
A cryptocurrency can become energy efficient by using alternative consensus mechanisms that are more energy-efficient than traditional Proof of Work (PoW) mechanisms. For example, some cryptocurrencies use Proof of Stake (PoS) or Proof of Authority (PoA) mechanisms, which require much less computational power and energy to verify transactions and maintain the network.
Other strategies that will drop power consumption include using more energy-efficient protocols and algorithms, improving hardware and software efficiency, and adopting renewable energy sources for mining and network operations.
Cryptocurrency developers can also focus on enhancing scalability and lowering transaction fees, which can help attract more users and reduce the overall energy usage of the network.
Ultimately, a cryptocurrency becomes energy-efficient when its developers prioritize sustainability and actively work towards lessenning its energy consumption and environmental impact.
