Ethereum's Green Revolution in 2025: Energy Use, Costs & Future Upgrades

In September 2022, Ethereum underwent a groundbreaking transformation known as the Merge, shifting from energy-intensive proof-of-work to an eco-conscious proof-of-stake consensus. This upgrade drastically cut the blockchain’s energy consumption by more than 99%, making Ethereum one of the greenest major cryptocurrencies in the market today. Beyond energy savings, the upgrade set a foundation for faster transactions and lower fees, revolutionizing the crypto landscape.

Key Highlights

• The Merge marked Ethereum's shift to proof-of-stake, significantly lowering energy use.
• Proof-of-stake validators are chosen randomly based on staked ETH, making the process more sustainable than mining.
• Ethereum’s gas fees dropped after the Merge, though not directly because of it, and remain higher than in early years.
• Future scalability upgrades promise enhanced speeds and reduced costs.

Ethereum’s Energy Impact in 2024

Ethereum, launched in 2015 by Vitalik Buterin, has grown into the second-largest cryptocurrency by market cap, valued at $466.67 billion as of May 2024. Its transition to proof-of-stake eliminated mining, cutting energy consumption from 21.41 terawatt-hours annually to a mere 0.0026 TWh, equivalent to 870 tonnes of CO2 emissions — a monumental improvement compared to Bitcoin’s 149 TWh yearly usage.

Unlike proof-of-work’s competitive mining, proof-of-stake relies on validators selected based on staked ether, greatly reducing electricity demand while maintaining network security and decentralization.

Understanding Ethereum Gas Fees

Ethereum’s transaction fees surged in 2020 due to demand spikes, with users bidding higher to prioritize their transactions. Attempts to regulate fees introduced base and priority fees (tips), but fee wars persisted. Although the Merge didn’t directly reduce gas fees, upcoming upgrades aim to bring costs down substantially.

Important Note

Ethereum is steadily evolving into a greener, more scalable blockchain with future improvements targeting efficiency and affordability.

Transaction Speeds and Scalability

The Merge laid the groundwork for future network enhancements. While immediate speed improvements were limited, forthcoming upgrades like proto-danksharding and full danksharding are expected to boost transaction throughput beyond 100,000 per second at significantly lower costs.

Is Ethereum Truly Green?

Post-Merge, nearly half of Ethereum’s energy comes from renewable sources such as wind and nuclear power, with the rest powered by natural gas, coal, and oil. Compared to other industries and major cryptocurrencies, Ethereum’s carbon footprint is impressively low, highlighting its commitment to sustainability.

Research from Cambridge Judge Business School confirms this cleaner energy mix, validating Ethereum’s greener status and potential for further eco-friendly upgrades.

Fast Fact

In May 2024, the SEC approved eight new spot Ether ETFs for trading on major exchanges like NYSE and Nasdaq, signaling increased mainstream adoption of Ethereum assets.

The Road Ahead: Ethereum’s Green Future

The March 2024 Dencun Upgrade introduced proto-danksharding, enabling more cost-effective data transmission on the mainchain, reducing gas fees, and enhancing scalability. Full danksharding will dramatically increase transaction capacity and lower fees, fostering a more sustainable, decentralized network.

Future improvements will also tackle censorship resistance, decentralization, block verification, and computational efficiency, all contributing to Ethereum’s green ambitions.

Quick Insight

Maximal Extractable Value (MEV) represents extra value validators or miners can earn beyond standard rewards, and minimizing MEV is part of Ethereum’s roadmap to fairness and efficiency.

While Ethereum’s eco-friendly upgrades continue, the energy demands of decentralized applications built atop the network remain a factor to watch as Web3 technologies evolve.

Web3 aims to reshape the internet by returning control of data and digital assets to users, with Ethereum positioned as a leading platform driving this revolution.

FAQs

Does Ethereum consume energy?

Yes, Ethereum uses energy to secure and operate its blockchain, though the shift to proof-of-stake has drastically reduced its consumption.

Is Ethereum environmentally friendly?

Post-Merge, Ethereum’s carbon footprint is significantly lower, with almost half of its energy sourced renewably, making it one of the greener blockchain platforms.

How much energy did Ethereum use before the Merge?

Before transitioning to proof-of-stake, Ethereum consumed approximately 21.41 terawatt-hours annually, emitting over 10 million tons of CO2.

Conclusion

Ethereum’s journey towards a faster, greener, and more accessible blockchain is well underway. The Merge and subsequent upgrades have drastically cut emissions and energy use, setting the stage for further innovations. While challenges remain, Ethereum is leading the charge in sustainable blockchain technology, balancing environmental responsibility with cutting-edge performance.
