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.
|Name||Population||Annual Electricity Consumption (TWh)|
|All of the world’s data centers||-||205|
|State of New York||19.3M||161|
|Walt Disney World Resort (Florida)||-||1|

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.

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.

How Affordable is Gas in Latin America?
This graphic looks at gas affordability in Latin America, showing how much a liter of gas costs in 19 countries, relative to average incomes.
How Affordable is Gas in Latin America?
As gas prices have risen around the world, not each region and country is impacted equally.
Globally, the average price for a liter of gas was $1.44 USD on June 13, 2022.
But the actual price at the pump, and how affordable that price is for residents, varies greatly from country to country. This is especially true in Latin America, a region widely regarded as one of the world’s most unequal regions in terms of its income and resource distribution.
Using monthly data from GlobalPetrolPrices.com as of May 2022, this graphic by Latinometrics compares gas affordability in different countries across Latin America.
Gas Affordability in 19 Different Latin American Countries
To measure gas affordability, Latinometrics took the price of a liter of gas in 19 different Latin American countries and territories, and divided those figures by each country’s average daily income, using salary data from Statista.
Out of the 19 regions included in the dataset, Venezuela has the most affordable gas on the list. In Venezuela, a liter of gas is equivalent to roughly 1.3% of the country’s average daily income.
|Country||Gas price as of May 2022 (USD)||% of average daily income|
|🇩🇴 Dominican Republic||$1.41||12.6%|
|🇸🇻 El Salvador||$1.14||9.2%|
|🇨🇷 Costa Rica||$1.42||5.9%|
|🇵🇷 Puerto Rico||$1.35||2.2%|
This isn’t too surprising, as Venezuela is home to the largest share of proven oil reserves in the world. However, it’s worth noting that international sanctions against Venezuelan oil, largely because of political corruption, have hampered the once prosperous sector in the country.
On the other end of the spectrum, Nicaragua has the least affordable gas on the list, with one liter of gas costing 14% of the average daily income in the country.
Historically, the Nicaraguan government has not regulated gas prices in the country, but in light of the current global energy crisis triggered in large part by the Russia-Ukraine conflict, the government has stepped in to help control the situation.
As the Russia-Ukraine conflict continues with no end in sight, it’ll be interesting to see where prices are at in the next few months.
Mapped: Which Ports are Receiving the Most Russian Fossil Fuel Shipments?
Russia’s energy exports have become a hot topic. See which ports received fossil shipments during the first 100 days of the Ukraine invasion
As the invasion of Ukraine wears on, European countries are scrambling to find alternatives to Russian fossil fuels.
In fact, an estimated 93% of Russian oil sales to the EU are due to be eliminated by the end of the year, and many countries have seen their imports of Russian gas plummet. Despite this, Russia earned €93 billion in revenue from fossil fuel exports in the first 100 days of the invasion.
While the bulk of fossil fuels travel through Europe via pipelines, there are still a number marine shipments moving between ports. The maps below, using data from MarineTraffic.com and Datalastic, compiled by the Centre for Research on Energy and Clean Air (CREA), are a look at Russia’s fossil fuel shipments during the first 100 days of the invasion.
Russia’s Crude Oil Shipments
Much of Russia’s marine shipments of crude oil went to the Netherlands and Italy, but crude was also shipped as far away as India and South Korea.
India became a significant importer of Russian crude oil, buying 18% of the country’s exports (up from just 1%). From a big picture perspective, India and China now account for about half of Russia’s marine-based oil exports.
It’s important to note that a broad mix of companies were involved in shipping this oil, with some of the companies tapering their trade activity with Russia over time. Even as shipments begin to shift away from Europe though, European tankers are still doing the majority of the shipping.
Russia’s Liquefied Natural Gas Shipments
Unlike the gas that flows along the many pipeline routes traversing Europe, liquefied natural gas (LNG) is cooled down to a liquid form for ease and safety of transport by sea. Below, we can see that shipments went to a variety of destinations in Europe and Asia.
Fluxys terminals in France and Belgium stand out as the main destinations for Russian LNG deliveries.
Russia’s Oil Product Shipments
For crude oil tankers and LNG tankers, the type of cargo is known. For this dataset, CREA assumed that oil products tankers and oil/chemical tankers were carrying oil products.
Huge ports in Rotterdam and Antwerp, which house major refineries, were the destination for many of these oil products. Some shipments also went to destinations around the Mediterranean as well.
All of the top ports in this category were located within the vicinity of Europe.
Russia’s Coal Shipments
Finally, we look at marine-based coal shipments from Russia. For this category, CREA identified 25 “coal export terminals” within Russian ports. These are specific port locations that are associated with loading coal, so when a vessel takes on cargo at one of these locations, it is assumed that the shipment is a coal shipment.
The European Union has proposed a Russian coal ban that is expected to take effect in August. While this may seem like a slow reaction, it’s one example of how the invasion of Ukraine is throwing large-scale, complex supply chains into disarray.
With such a heavy reliance on Russian fossil fuels, the EU will be have a busy year trying to secure substitute fuels – particularly if the conflict in Ukraine continues to drag on.
