Solana Network Can Run For An Hour On Less Energy Than Is Required For A Single Bitcoin Transaction: Report – Solana (SOL/USD)

Ethereum ETH/USD has no shortage of supporters in the Web3 world, but the award for “most unexpected endorsement” goes to Greenpeace for endorsing Ethereum based on the Merge which moves it to a more environmentally friendly Proof-of-Stake (POS) validation system vs. the original Proof-of-Work (POW) system. If you’ve not been following the significance of POW vs. POS, the tl;dr version is POW simply requires more computational power than POS. So the world will have fewer cryptographic computations and more energy for bunnies and flowers. 

But before we send Greenpeace invitations to our discord servers, note that they are quite critical of Bitcoin BTC/USD. Greenpeace stated in their press release, “Ethereum’s long-awaited ‘merge’ to a proof of stake consensus mechanism uses 99.95% less energy, leaving Bitcoin as the largest cryptocurrency using the outmoded high-energy proof of work consensus mechanism.”

Scott Melker, crypto analyst, writer, and podcaster, observed in his newsletter “The Wolf’s Den” that the funding behind the $1 million campaign against Bitcoin suggests certain conflicts of interest.

“I’m all for miners cleaning up their operations, but that’s not what this campaign is about. Greenpeace’s crypto campaign started in March, backed by crypto billionaire Chris Larson, Ripple’s executive chairman. Ripple is funding the environmental campaign against Bitcoin,” Melker wrote.

Serendipitously, the Solana SOL/USD Foundation has released its second yearly report on the carbon footprint of the Solana blockchain

Solana uses a unique approach, with a proof-of-history (POH) protocol which makes block confirmation faster than POS. The POH-based Solana is also far more energy efficient. In fact, their home page has graphics (without citation) that tell the tale poignantly – Solana is just short of being 50 times more efficient than Ethereum and thousands of times more efficient than Bitcoin.

In their latest report, based on a “novel dataset and analysis” by Othersphere, led by Robert Murphy, they conducted a carbon assessment.


Some highlights of this report include:

The assessment of the overall carbon footprint of the network is 3,412 tons of CO2 per year, up 26% from 2,707 tons of CO2 per year in March 2022.

  • The overall carbon footprint is measured by adding emissions due to power consumption (1,772 tons CO2 per year) with emissions due to hardware production, also known as e-waste (1,639 tons CO2 per year).
  • The primary reasons for the changes are:

    • The incorporation of emissions due to hardware production (e-waste) into the energy use report, which added 1,639 tons of CO2 per year.
    • Decreased emissions, resulting from a reduction in the estimated power consumption per validator node, which fell 48 percent from 984W to 509W per validator node.
    • Inclusion of data center-specific renewable energy utilization, which lowered average network carbon intensity by roughly 10% from 198 to 180 g of CO2 per KWh.

The report also states: “While there are always improvements to be made, when it comes to emissions reduction, it’s important to note that Solana remains an incredibly energy-efficient blockchain and that the network is carbon neutral due through the Foundation’s purchase of offsets. This analysis found that running the entire Solana network for an hour uses less energy than a single Bitcoin transaction.”

The Solana Foundation stated in the report that they continue to look for ways to improve their energy efficiency, including:

  • The use of compressed NFTs, which make it possible to mint 8 to 10 NFTs in a single transaction.
  • Doubling of Transaction Size, which increases the per-block efficiency of the chain and enables the network to accomplish more in a single transaction for a minimal increase in computing power. 

The last word

If we hope to reach a mainstream buying audience, the crypto world needs to address concerns about carbon footprint. We can speculate all we like about whether refrigerators or washing machines use more energy – that isn’t really the point. The point is the bull run that we enjoyed for nearly two years relies on mainstream investment, and mainstream investors want environmental impact addressed. 

Addressing the environmental concerns of crypto, as projects like Solana seek to do, is future-proofing against public opinion. Buyers want carbon-neutral, and, ultimately, they will have it. Bitcoin will never change its consensus mechanism, but there are some Bitcoin supporters who have suggested that Bitcoin mining can become carbon negative. Environmental Analyst Daniel Batten suggested Bitcoin mining can become carbon negative by Q4 of 2024 by “burning previously vented methane.”
