Analysis: mining bitcoin uses 91 TW/h of electricity annually, ~0.5% of all electricity consumed globally or 7x Google's total usage, and grew 10x in five years
This analysis is the moment bitcoin's energy use stopped being an enthusiast talking point and became a macro number: 91 TWh a year, roughly half a percent of all electricity on earth, seven times Google's total consumption, after growing tenfold in five years. It caps a decade-long arc that started with Chinese factory floors mining thousands of bitcoins a month and moved through early attempts to price the network's footprint per transaction.
The piece also lands mid-dispute over how these numbers are even measured — experts had already flagged that most projections traced back to a single source with questionable methodology — so the NYT's framing matters for what regulators and utilities do next.
Google becomes the reference point for scale — a comparison that drags big tech into the conversation about compute's power appetite, not just crypto's.
Second-order effects
Utilities and state policymakers gain a concrete constituency problem — ratepayers subsidizing industrial mining load — forcing siting rules, tariff designs, and moratoria debates around mine locations.
Per-transaction accounting sharpens as the political unit of criticism: earlier work pegged one Bitcoin transaction at roughly 215 KWh, about a week of household electricity, giving critics a household-relatable figure even as its methodology stays contested.
Third-order effects
Proof-of-work's energy intensity turns from a technical property into a regulatory variable: where mining physically sits increasingly follows cheap power and permissive rules rather than where coins are traded.
If large-scale computing keeps competing with households for grid capacity — first bitcoin, later other compute-hungry workloads — power access becomes the binding constraint on where digital infrastructure gets built, and utilities become de facto gatekeepers of the industry's growth.
The trend: Bitcoin mining has scaled from garage rigs to a utility-scale industry whose siting decisions are shaped by electricity costs, grid strain, and resource accounting.
Bitcoin's energy use is close to half-a-percent of all the electricity consumed in the world. This is more than seven times as much electricity as all of Google's global operations and is similar to Washington State's consumption. https://www.nytimes.com/... https://twitter.com/.…

By simply existing, Bitcoin, the most popular cryptocurrency, uses astonishing amounts of electricity. The Bitcoin network consumes around 91 terawatt-hours of electricity annually, more than the country of Finland. https://www.nytimes.com/... https://twitter.com/...

It's common to see comparisons of BTC's energy use to various countries/states, but “seven times as much electricity as Google” is a great comparison. Imagine what you could do with 7x Google's compute power instead of merely implementing a janky payment system. https://twitter.c…

I frequently feel like I'm the only one in crypto who thinks this is a legitimate and not necessarily overstated concern :( https://twitter.com/...

Whatever you think about Bitcoin, it is not providing .5% of the value produced by electricity consumption in the world. https://twitter.com/...

Great explanatory piece about the electric cost of Bitcoin, which uses more electricity than many nations. “That usage, which is close to half-a-percent of all the electricity consumed in the world, has increased about tenfold in just the past five years.” https://www.nytimes.com…

You know how sometimes your laptop or phone will get stuck in some process loop and just runs hotter and hotter and performance continues to degrade worse and worse hotter and hotter worse and worse. Imagine that as currency. https://twitter.com/...

And worse news: As long as Bitcoin's price is high, this consumption is inevitable. The system is deliberately anti-efficient. The only way to drop the power consumption by 90% is for the price to drop 90% Bitcoin really is a crime against humanity. https://twitter.com/...

The Bitcoin network uses about the same amount of electricity as Washington State does yearly, more than a third of what residential cooling in the United States uses up, and more than seven times as much electricity as all of Google's global operations. https://www.nytimes.com/.…

Mining activities for decentralized digital currencies (e.g. Bitcoin) consume massive amounts of electricity, mostly from fossil fuels, resulting in extraordinary carbon emissions. Sorry Elon, but the coins are just too costly. https://www.nytimes.com/... https://www.nytimes.com/…

This is a major concern: “The Bitcoin network uses more than 7x times as much electricity as all of Google's global operations. Could it be greener? Using renewables to power mining means it won't be available to power a home, a factory or an EV.” https://www.nytimes.com/...
