Visualizing the Power Consumption of Bitcoin Mining

Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.

Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.

Why Does Bitcoin Mining Require So Much Power?

When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.

Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.

These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.

Putting Bitcoin’s Power Consumption Into Perspective

On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.

NamePopulation Annual Electricity Consumption (TWh)
China1,443M6,543
United States330.2M3,989
All of the world’s data centers-205
State of New York19.3M161

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.

For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.

Where Does This Energy Come From?

In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.

Here’s how the share of cryptominers that use each energy type vary across four global regions.

Solar12%13%17%17%
Geothermal8%0%0%6%

Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.

Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.

Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.

Towards a Greener Crypto Future

As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.

Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.

“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry

This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.

4 Reasons Why You Should Invest in Lithium

Lithium’s importance in powering EVs makes it a linchpin of the clean energy transition and one of the world’s most precious minerals.

In this graphic, Visual Capitalist partnered with EnergyX to explore why now may be the time to invest in lithium.

1. Lithium Prices Have Dropped

One of the most critical aspects of evaluating an investment is ensuring that the asset’s value is higher than its price would indicate. Lithium is integral to powering EVs, and, prices have fallen fast over the last year:

DateLiOH·H₂O*Li₂CO₃**
Feb 2023$76$71
March 2023$71$61
Apr 2023$43$33
May 2023$43$33
June 2023$47$45
July 2023$44$40
Aug 2023$35$35
Sept 2023$28$27
Oct 2023$24$23
Nov 2023$21$21
Dec 2023$17$16
Jan 2024$14$15
Feb 2024$13$14

Note: Monthly spot prices were taken as close to the 14th of each month as possible.

**Lithium carbonate MB-LI-0029

2. Lithium-Ion Battery Prices Are Also Falling

The drop in lithium prices is just one reason to invest in the metal. Increasing economies of scale, coupled with low commodity prices, have caused the cost of lithium-ion batteries to drop significantly as well.

In fact, BNEF reports that between 2013 and 2023, the price of a Li-ion battery dropped by 82%.

YearPrice per KWh
2023$139
2022$161
2021$150
2020$160
2019$183
2018$211
2017$258
2016$345
2015$448
2014$692
2013$780

3. EV Adoption is Sustainable

One of the best reasons to invest in lithium is that EVs, one of the main drivers behind the demand for lithium, have reached a price point similar to that of traditional vehicle.

According to the Kelly Blue Book, Tesla’s average transaction price dropped by 25% between 2022 and 2023, bringing it in line with many other major manufacturers and showing that EVs are a realistic transport option from a consumer price perspective. 

ManufacturerSeptember 2022September 2023
BMW$69,000$72,000
Ford$54,000$56,000
Volkswagon$54,000$56,000
General Motors$52,000$53,000
Tesla$68,000$51,000

4. Electricity Demand in Transport is Growing

As EVs become an accessible transport option, there’s an investment opportunity in lithium. But possibly the best reason to invest in lithium is that the IEA reports global demand for the electricity in transport could grow dramatically by 2030:

Transport Type202220252030
Buses 🚌23,000 GWh50,000 GWh130,000 GWh
Cars 🚙65,000 GWh200,000 GWh570,000 GWh
Trucks 🛻4,000 GWh15,000 GWh94,000 GWh
Vans 🚐6,000 GWh16,000 GWh72,000 GWh

The Lithium Investment Opportunity

Lithium presents a potentially classic investment opportunity. Lithium and battery prices have dropped significantly, and recently, EVs have reached a price point similar to other vehicles. By 2030, the demand for clean energy, especially in transport, will grow dramatically. 

With prices dropping and demand skyrocketing, now is the time to invest in lithium.

EnergyX is poised to exploit lithium demand with cutting-edge lithium extraction technology capable of extracting 300% more lithium than current processes.
