We need to tackle these environmental costs to make sure blockchain can grow and be adopted sustainably.
Energy Consumption and Greenhouse Gas Emissions
The Bitcoin mining network used 173.42 Terawatt hours of electricity in 2020-2021. That’s as much as the 27th largest country in the world. This led to 85.89 Mt of CO2 emissions, similar to burning 84 billion pounds of coal or running 190 natural gas plants.
The energy for Bitcoin mining mostly comes from fossil fuels. Coal makes up 45%, and natural gas 21%. Only a small part comes from renewable sources like hydropower, solar, and wind. This shows we need to act fast to make blockchain operations more sustainable.
Water and Land Footprints of Blockchain Mining
Blockchain mining also uses a lot of water and land. In the same time, it used enough water to fill over 660,000 Olympic-sized swimming pools. The land used was 1.4 times the size of Los Angeles.
“The environmental footprint of blockchain operations is a growing concern that must be addressed to ensure the sustainable development and adoption of this promising technology.”
As blockchain technology grows and gets more use, we must work together to lessen its environmental impact. We can do this by focusing on energy efficiency, using more renewable energy, and finding sustainable mining ways. This way, blockchain can reach its full potential without harming the environment too much.
Consensus Mechanisms and Environmental Impact
The consensus mechanism used by a blockchain network greatly affects its environmental impact. Traditional proof-of-work (PoW) mechanisms, like those used by Bitcoin, are very energy-intensive. They lead to large carbon, water, and land footprints for blockchain operations.
In contrast, proof-of-stake (PoS) mechanisms, such as Ethereum’s “The Merge,” are much more energy-efficient. They are also more sustainable.
Proof-of-Work vs. Proof-of-Stake: A Sustainability Comparison
The PoW mechanism verifies transactions through energy-intensive mining. Powerful computers compete to solve complex mathematical problems. This process uses a lot of electricity and produces a lot of greenhouse gas emissions.
The Bitcoin network alone uses more electricity each year than some countries. This is a big problem for the environment.
The PoS mechanism, on the other hand, verifies transactions by staking existing cryptocurrency holdings. This method is much more energy-efficient. It reduces environmental impact by up to 99.95% compared to PoW.
Blockchains like Cardano, Polkadot, and Ethereum 2.0 after its transition use PoS. They are better for the environment.
Other consensus mechanisms, such as Delegated Proof of Stake (DPoS) and Proof of Authority (PoA), also offer energy-efficient alternatives. DPoS selects a limited number of nodes for validating transactions. PoA uses a pre-selected group of validators known for their reputation and trustworthiness.
As blockchain networks evolve, choosing the right consensus mechanism is key to their sustainability. Researchers are looking into AI-enhanced and quantum state-based consensus protocols. These could further reduce the environmental impact of blockchain operations.
