Bitcoin (BTC) Mining Isn’t the Climate Villain Many Think: ESG Expert Says

Claims that Bitcoin mining wastes energy or destabilizes networks are contradicted by university research and real-world data.

Bitcoin mining has long been portrayed as damaging to the climate. Many argued that it wastes enormous amounts of energy, strains power grids and undermines global climate goals – claims that have become a common part of public debate.

However, this narrative is increasingly challenged as more data and analysis emerges. Claims that Bitcoin mining wastes energy or destabilizes networks are contradicted by university research and real-world data.

Debunking Bitcoin Mining Myths

ESG expert Daniel Batten has pushed back against the misconceptions surrounding Bitcoin mining, saying many claims are not supported by evidence and persist due to outdated assumptions. In his analysis of Bitcoin and energy consumption, Batten says explained that the idea that Bitcoin uses large amounts of energy, water or e-waste per transaction is incorrect, while pointing to multiple peer-reviewed studies and research from the University of Cambridge that have shown that BTC’s resource consumption is not determined by transaction volume.

As a result, transaction activities can scale without increasing energy, water, or hardware use. He traces the origins of the “per transaction” story to a 2018 comment by Alex de Vries, which he says was later debunked but widely quoted. This has led to long-standing misunderstandings.

As for e-waste specifically, Batten cited findings from Cambridge in 2025 showing that previous estimates overestimated Bitcoin’s e-waste by more than 1,200%. The researcher also disputed claims that Bitcoin mining destabilizes power grids. Instead, he cited a growing number of independent studies showing that mining can actually support grid stability because of its flexible and interruptible load profile, especially on grids with high levels of wind and solar energy.

Meanwhile, studies from Duke University and other researchers have shown that Bitcoin mining can provide network balancing and support services, a conclusion that Batten says is supported by real-world data from the ERCOT network in Texas. According to ERCOT data, BTC mining has contributed to near-daily grid stabilization through demand response and frequency regulation, including during extreme events such as the July 2022 Texas heat wave, while only one mild destabilizing incident has been documented.

Electrified, grid-friendly and cheaper

Batten even disputed the claim that Bitcoin mining increases electricity prices for consumers, while citing data on electricity costs in the US and Texas between 2021 and 2024 that show no abnormal increase in regions with high mining activity. He stated that BTC mining can reduce system costs by monetizing excess renewable energy, reducing curtailment, deferring network upgrades and replacing the need for additional gas peaker power plants.

Cases in Norway and Kenya show that Bitcoin mining has been linked to lower electricity prices. On broader energy comparisons, Batten echoes Cambridge University’s view that comparing BTC’s energy consumption with entire countries is misleading. He says climate policy is aimed at changing the way energy is produced and managed, not just reducing overall consumption.

He further noted that BTC mining is fully electrified, highly flexible and capable of reducing methane emissions. Batten disputed claims that the crypto asset has an unusually high carbon footprint, giving Cambridge estimates of around 39.8 MtCO2e of emissions, all from electricity consumption. Data also showed that Bitcoin mining has crossed the 50% renewable energy threshold globally.
