Visualizing Countries by Share of Earth’s Surface

There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.

Today’s visualization uses data primarily from the United Nations Statistics Division (UNSD) to rank the world’s countries by their share of Earth’s surface.

Breakdown of Countries Share of Earth’s Surface

The largest countries by surface area are Russia (3.35%), Canada (1.96%), and China (1.88%).

Together they occupy roughly 7.2% of Earth’s surface. Russia is so big that even if we divided the country between its Asian and European sections, those new regions would still be the largest in their respective continents.

Antarctica, although not a country, covers the second largest amount of land overall at 2.75%. Meanwhile, the other nations that surpass the 1% mark for surface area include the United States (1.87%), Brazil (1.67%), and Australia (1.51%).

The remaining 195 countries and regions below 1%, combined, account for the other half of Earth’s land surface. Among the world’s smallest countries are the island nations of the Caribbean and the South Pacific Ocean. However, the tiniest of the tiny are Vatican City and Monaco, which combine for a total area of just 2.51 km².

The remaining 70% of Earth’s surface is water: 27% territorial waters and 43% international waters or areas beyond national jurisdiction.

Areas Beyond National Jurisdiction

In the past, nations adhered to the freedom-of-the-seas doctrine, a 17th century principle that limited jurisdiction over the oceans to a narrow area along a nation’s coastline. The rest of the seas did not belong to any nation and were free for countries to travel and exploit.

This situation lasted into the 20th century, but by mid-century there was an effort to extend national claims as competition for offshore resources became increasingly fierce and ocean pollution became an issue.

In 1982, the United Nations adopted the Law of the Sea Convention which extended international law over the extra-territorial waters. The convention established freedom-of-navigation rights and set territorial sea boundaries 12 miles (19 km) offshore with exclusive economic zones up to 200 miles (322 km) offshore, extending a country’s influence over maritime resources.

Does Size Matter?

The size of countries is the outcome of politics, economics, history, and geography. Put simply, borders can change over time.

In 1946, there were 76 independent countries in the world, and today there are 195. There are forces that push together or pull apart landscapes over time. While physical geography plays a role in the identity of nations, Sheikh Zayed bin Sultan Al Nahyan, the former ruler of UAE, a tiny Gulf nation, put it best:

“A country is not measured by the size of its area on the map. A country is truly measured by its heritage and culture.”

Visualizing the Depth of the Great Lakes

The five Great Lakes account for 21% of the world’s total freshwater. This bathymetric visualization dives into just how deep they are.

Published

Visualized: The Depth of The Great Lakes

Click here to view the interactive version of the visualization on Tableau.

As the seasons change, it’s natural to want to enjoy the outdoors to the fullest. The Great Lakes, a distinct geographical region sandwiched between the U.S. and Canada, provides immense opportunity for millions of tourists to do just that every year.

But did you know that altogether the Great Lakes contain 21% of the world’s surface freshwater by volume—or 84% of the surface freshwater in North America?

This bathymetric visualization, created by Alex Varlamov, helps put the sheer size and depth of all five of the Great Lakes into perspective.

What is Bathymetry?

Bathymetry is the study of the underwater depth of ocean or lake floors, a geographical science that falls under the wider umbrella of hydrography.

In essence, it is the underwater equivalent of topography. Contour lines help to represent and study the physical features of bodies of water, from oceans to lakes.

Most bathymetric studies are conducted via sonar systems, transmitting pulses that ‘ping’ off the ocean and lake floor, uncovering what lies below.

The Depth of the Great Lakes, Compared

High on the list of the world’s largest lakes, the five Great Lakes altogether account for over 244,700 km² (94,250 mi²) in total surface area. That’s bigger than the entire United Kingdom.

Lake Superior emerges, well, superior in terms of total surface area, water volume, and both average and maximum depth.

(1,333 ft)

Lake Erie is by far the shallowest of the lakes, with an average depth of just 19 meters (62 ft). That means on average, Lake Superior is about eight times deeper.

With that in mind, one drawback of the visualization is that it doesn’t provide an accurate view of how deep these lakes are in relation to one another.

For that, check out this additional visualization also created by Alex Varlamov, which is scaled to the same 20 meter step—in this view, Lake Erie practically disappears.

More than Meets the Eye

The Great Lakes are not only notable for their form, but also their function—they’re a crucial waterway contributing to the economy of the area, supporting over 50 million jobs and contributing $6 trillion to gross domestic product (GDP).

Together, the five Great Lakes feed into the Atlantic Ocean—and when we expand the scope to compare these lakes to vast oceans, trenches, and drill holes, the depth of the Great Lakes barely scratches the surface.

Visualizing the Power Consumption of Bitcoin Mining

Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?

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.

Editor’s note: Numbers in each column are not meant to add to 100%

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.
