Consumption vs Major Industries

Bitcoin’s annual energy consumption is estimated at 173 TWh in 2025, while gold mining uses roughly 240 TWh per year, making gold ~39% higher.
Global data centers consume around 415 TWh annually (for all services), about 1.5% of global electricity, with the U.S. making up 45% of this share.
Oil and gas industries use thousands of terawatt-hours, orders of magnitude more than Bitcoin; e.g., ExxonMobil alone consumed over 1,500 TWh in 2024.
Steel and cement sectors each consume well over 2,000 TWh per year globally, over 10× Bitcoin’s usage.
The U.S. share of national electricity used by crypto mining is 0.6%–2.3% in certain states for 2025.
Gold mining emits 9 tons of CO₂ per Bitcoin’s worth of gold, while mining a single Bitcoin emits about 223 tons of CO₂, showing higher carbon intensity for Bitcoin.
Automotive (including EVs) and electronics manufacturing can match or top Bitcoin’s energy use locally, with certain EV gigafactories drawing 8–10 TWh yearly.
Bitcoin’s energy footprint is forecasted to grow faster than many traditional sectors due to scaling and price surges; a 400% price boom triggered a 140% rise in energy use from 2021-2022.

Hourly Electricity Use: Bitcoin Mining vs Appliances

Bitcoin mining uses 4.6 kWh per hour, close to a clothes dryer’s 5.0 kWh.
It consumes more than an electric kettle (3.5 kWh) and a leaf blower (2.5 kWh).
Appliances like ACs, dishwashers, and mowers use about 1.5 kWh, roughly one-third of Bitcoin mining.

Bitcoin vs Traditional Banking Energy Use

Global banking consumes 258.85 TWh annually, compared to Bitcoin’s 167.14 TWh, making banks use 35% more energy.
Some studies claim the banking sector is 56× more energy-intensive than Bitcoin when comparing all infrastructure layers.
The Visa network alone uses 7.81 TWh per year, while Bitcoin’s annual energy usage ranges from 88–150 TWh.
Global banking infrastructure, including ATMs and branches, consumes about 0.2% of worldwide electricity, similar to a small nation’s demand.
Bitcoin processes far fewer transactions, causing its energy per transaction to exceed banking by 2–3 orders of magnitude.
Bitcoin miners sustain a power draw, so network energy is not directly scaled by transaction count, unlike banking.
Physical bank branches add 22.68 TWh, and ATMs use 2.91 TWh yearly; continuous power sources are absent in Bitcoin.
Studies argue that infrastructure comparisons can be misleading; estimates vary 25–50× depending on modeling inclusions.
Some analyses suggest Bitcoin mining is a million times more efficient per payment in select metrics, but is limited by transaction scaling.
Global banks lack transparent public reporting, so consumption figures may be underestimated by 10–20%.

Other Cryptocurrencies (Energy Comparison)

Bitcoin, Proof of Work, generally consumes orders of magnitude more energy than Proof of Stake networks.
Ethereum’s shift to PoS in 2022 reduced its energy usage by over 99%, making Bitcoin much more energy‑intensive in contrast.
Some PoS blockchains claim energy usage that is negligible compared to the power draw in traditional finance or Bitcoin.
Litecoin, Monero, and Bitcoin Cash also share mining energy burdens, but their hashrates are lower, so their absolute consumption is smaller.
In cross‑crypto metrics, average energy per USD mined is ~5 kWh for Bitcoin, ~2 kWh for Ethereum pre‑merge.
Some hybrid or alternative consensus chains, e.g., DAG, aim for minimal energy consumption footprints.
The gap between Bitcoin and low‑energy cryptos may widen as Bitcoin demand rises and difficulty increases.

Critics question the consistency of renewable claims and whether miners displace other users of renewables.
Some subsidized or off‑grid mining connects directly to solar, wind farms, or geothermal sites to avoid grid carbon intensity.

Environmental Impact and Carbon Emissions of Bitcoin Mining

A single Bitcoin transaction in 2025 emits ~712 kg CO₂, roughly equal to 1.58 million Visa transactions.
The network’s total carbon emissions for 2025 are estimated to be ~98 million metric tons CO₂.
The mining industry contributes ~139 million tonnes CO₂‑eq if accounting for broader GHG sources.
Life‑cycle assessments suggest up to 80% of environmental impact may originate from mining hardware production rather than just operation.
Bitcoin’s e‑waste footprint is significant; decommissioned ASICs contribute to electronic waste streams.
Water consumption, land use, and local emissions, cooling, and diesel backup compound the footprint.
In regions with coal or gas electricity, displaced mining can increase net emissions elsewhere, carbon leakage, when bans push miners to dirtier grids.

Hardware Efficiency Trends

In 2025, top ASIC miners achieved ~46 J/TH, about a 12% improvement over 2024’s best models.
Some leading models now operate in the 25–30 J/TH range under ideal conditions.
The average mining farm’s PUE improved to ~1.18, down from ~1.23, meaning less overhead energy wasted on cooling.
Earlier ASICs often ran above 80–90 J/TH; the shift to modern 5nm and 3nm chip designs has driven efficiency leaps.
Some projections aim for ≤ 5 J/TH rigs by late 2025–2026 through chip innovations.
Efficiency gains are constrained by diminishing returns; improvements below ~10 J/TH require disproportionate cost.
Mining operators also refine thermal design, airflow, and cooling to reduce idle wattage lost per hash.
Efficiency wins in hardware only translate to real energy savings if deployed at scale; older rigs often operate inefficiently or retire early.

Hashrate Trends

Russia holds ~15.5% of mining capacity as of 2025.
Kazakhstan’s share dropped to ~2.1% in Q4 2025, reflecting stricter regulation and energy constraints.
Paraguay, leveraging >99% hydro, claims ~3.9% of global mining share.
Hashrate growth pressures all miners, pushing them toward more efficient machines or exiting.

Methods for Estimating Bitcoin’s Energy Consumption

Cambridge CCAF’s annual best-guess energy estimate for Bitcoin in 2025 is 95.5 TWh, with a daily power demand of about 13 GW.
Top-down models link mining revenues and energy demand, assuming electricity is 51.05% of total miner income.
Bottom-up methods add reported miner wattage and usage rates, but often under‑represent downtime, leading to 10–20% errors.
Cambridge’s hybrid models now adjust for hardware obsolescence and regional electricity mixes, yielding emission deviations up to 16%.
Using 25 J/TH versus 50 J/TH can halve or double a model’s estimated consumption, illustrating the critical impact of average efficiency assumptions.
Life cycle energy models, factoring in manufacturing and disposal, can raise total footprint estimates by 8–12%.
Satellite imagery and grid load data are used in 2025 to validate site activity and correct for opaque miner reporting.
Real-time telemetry and blockchain-based energy logs now cover at least 13 countries, improving reporting accuracy.
The kWh-per-transaction method is increasingly criticized, as network scaling and batching can skew averages by 2–3x.
