Bitcoin Mining and Climate Change: Why ESG Experts Say the Story Is Wrong

Bitcoin mining is often seen as harming the environment, straining grids, and wasting energy.

Takeaways

New research challenges the idea that Bitcoin (BTC) mining is a major climate threat, citing outdated assumptions and flawed comparisons.
ESG expert Daniel Batten says evidence shows Bitcoin mining can support grid stability and renewable energy use.
Data from universities and power grids suggest mining may even help lower system-wide energy costs in some regions.

For years, Bitcoin mining has been portrayed as a major environmental problem. Critics have argued that it wastes vast amounts of energy, strains power grids, and works against global climate goals. These claims have shaped public debate and influenced policy discussions around digital assets.

However, this long-standing narrative is now being questioned as more data and academic research come to light. According to ESG analyst Daniel Batten, many of the most common criticisms of Bitcoin mining are not supported by evidence and continue to circulate due to outdated assumptions.

Challenging Common Myths About Bitcoin Mining

Batten points out that a key misunderstanding lies in how Bitcoin’s energy use is measured. He explains that claims about energy, water, or electronic waste “per transaction” are misleading. Research from Cambridge University shows that Bitcoin’s energy consumption is not driven by transaction volume. This means the network can process more transactions without increasing its use of energy, hardware, or water.

According to Batten, the “per transaction” narrative can be traced back to a 2018 commentary by Alex de Vries, which was later challenged by peer-reviewed studies but continued to be widely cited. This, he says, created long-lasting misconceptions.

On electronic waste, Batten refers to Cambridge findings published in 2025, which revealed that earlier estimates overstated Bitcoin’s e-waste by more than 1,200%. These newer figures suggest the environmental impact of mining hardware has been significantly exaggerated.

Grid Stability, Not Grid Stress

Another frequent criticism is that Bitcoin mining destabilizes electricity grids. Batten disputes this, citing a growing body of independent research showing the opposite. Studies from Duke University and others indicate that Bitcoin mining can support grid stability because it operates as a flexible and interruptible load.

Real-world data from Texas backs this up. Records from ERCOT, which manages the state’s power grid, show that Bitcoin miners regularly participate in demand response and frequency regulation. During the July 2022 heatwave, mining operations reduced consumption to help stabilize the grid, with only one minor destabilizing incident recorded.

Electrified, Flexible, and Cost-Effective

Batten also challenges the idea that Bitcoin mining raises electricity prices for consumers. He points to US and Texas data between 2021 and 2024, which show no unusual price increases in regions with high mining activity. In some cases, such as Norway and Kenya, mining has even been linked to lower electricity prices.

He argues that Bitcoin mining can reduce system costs by using excess renewable energy, cutting curtailment, delaying expensive grid upgrades, and reducing the need for gas-powered peaker plants. Batten also notes that Bitcoin mining is fully electrified and can help reduce methane emissions.

Cambridge estimates put Bitcoin’s annual emissions at around 39.8 MtCO₂e, all from electricity use. Importantly, global Bitcoin mining has now crossed a 50% sustainable energy threshold, further weakening claims that it has an unusually high carbon footprint.
