Cambridge Report: Ethereum Annual Power Use Fell to 7.87 GWh After the Merge
A report from the Cambridge Centre for Alternative Finance found that Ethereum’s annual electricity consumption dropped to 7.
A report from the Cambridge Centre for Alternative Finance found that Ethereum’s annual electricity consumption dropped to 7.87 GWh following the network’s transition from proof-of-work to proof-of-stake, known as the Merge.
What the Cambridge report found
The Cambridge report puts Ethereum’s post-Merge annual power consumption at 7.87 GWh. The figure represents a dramatic reduction from the energy-intensive proof-of-work consensus mechanism the network previously relied on.

KEY POINTS
- Cambridge researchers measured Ethereum’s annual electricity use at 7.87 GWh after the Merge.
- The Merge shifted Ethereum from proof-of-work mining to proof-of-stake validation.
- The report comes from the Cambridge Centre for Alternative Finance, which also tracks Bitcoin energy consumption.
The Merge, which took place in September 2022, eliminated the need for energy-intensive mining hardware. Validators now secure the network by staking ETH rather than competing to solve computational puzzles.

The Cambridge Centre for Alternative Finance has long been recognized for its work estimating cryptocurrency energy usage, most notably through its detailed methodology reports. Its Bitcoin Electricity Consumption Index remains one of the most widely cited benchmarks in blockchain sustainability research.

Why this figure matters for Ethereum’s narrative
Energy consumption has been one of the most persistent criticisms leveled at blockchain networks. Ethereum’s shift to proof-of-stake was explicitly designed to address that concern, and the Cambridge data provides an independent, institutional measurement of the result.
The 7.87 GWh figure gives Ethereum advocates a concrete, peer-reviewed reference point when responding to environmental critiques. For context, that level of annual consumption is orders of magnitude below what proof-of-work networks require to operate.
The report arrives as the broader crypto industry continues to face scrutiny over its environmental footprint. While Bitcoin’s energy debate remains active, Ethereum’s post-Merge efficiency has become a separate conversation within institutional circles evaluating blockchain infrastructure for enterprise adoption.
For investors and developers building on Ethereum, the Cambridge data reinforces the network’s positioning as an energy-efficient layer-1 platform, a factor that increasingly influences institutional and enterprise decisions around blockchain infrastructure.
