View a ranking of the countries with the largest helium reserves, led by the US

Learn how helium is used in the US, the world's largest producer of the noble gas

About 44% of the global supply comes from the US, as much as the next two biggest producers—Qatar and Russia—combined. According to the US Geological Survey, more than half of this helium is used in scientific and engineering equipment (22%), non-welding-related manufacturing and fabrication (17%), and as a lifting agent (17%).

As of 2025, the US and Qatar dominate global helium production

The US's 42.6% share includes helium imported from Canada and refined within the states. Geopolitical conflicts can cause supply disruptions that impact several advanced technologies, including semiconductor manufacturing, aerospace systems, and medical imaging.

Why stories about helium 'running out' indicate market volatility rather than scarcity

Only a few locations on Earth contain natural gas reserves with sufficiently high helium concentrations to make their extraction commercially viable, and geopolitical conflicts in these areas significantly affect helium production. This makes cost a major impediment to helium availability, particularly for scientific research, amid growing demand and ongoing depletion of reserves that took billions of years to form.

A visit to the Federal Helium Reserve, which once supplied up to 30% of US helium

The underground storage facility in Amarillo, Texas, was established by the Helium Act in 1925, when helium was viewed as a strategic resource whose export could enable other nations to use it for military airships. The Helium Privatization Act of 1996 instructed the Department of the Interior to begin selling off the facility and reserve, with the final sale occurring in 2024.

An overview of helium, the nonrenewable resource that's lighter than air

The second element in the periodic table naturally forms deep underground over the course of billions of years through the decay of radioactive elements, but it is used and lost to space at rates faster than it is generated. Because of this and its extensive applications in scientific technologies, scientists continue to seek avenues for its exploration, storage, and recycling.

As of 2024, the nation with the largest proven oil reserves is Venezuela

According to estimates derived from available geological and engineering data, the South American country possesses about 303 billion barrels of underground crude oil, followed by Saudi Arabia (267.2 billion) and Iran (208.6 billion). Many of the largest reserves are held by members of the Organization of the Petroleum Exporting Countries.

As of 2022, the US accounted for nearly one-fifth of global oil production

By 2022, the US had cemented its position as the world’s top oil producer with close to 18 million barrels per day. This eclipsed Saudi Arabia and Russia.

The industrial methods for recovering helium, including filters and cryogenic separation

Membranes with microscopic pores of varying sizes can be used to selectively filter out components of natural gas, including helium, which can then be concentrated. Because helium requires the lowest temperature of all elements to condense into a liquid, extracted natural gas can also be cooled until only helium remains as a gas.

Explore a map of data centers worldwide

As of February 2026, the US has more data centers (over 4,000) than the next 15 countries combined, thanks to years of investment by cloud service providers and technology companies. The next largest data center footprints come from the UK and Germany, with about 500 facilities each, followed by China with about 370.

About 10% of the world's crude oil and 32% of its natural gas is reached via fracking

Most of the world's shale oil resources—which are recoverable via fracking—are found in Russia, the US, China, Argentina, and Libya. The majority of equivalent shale gas resources are found in China, Argentina, Algeria, the US, Canada, and Mexico.

As of 2024, China is the largest overall contributor to global greenhouse gas emissions

Due to its large population, the nation's per capita emissions continue to lag behind those of the US, Canada, Russia, Australia, and Saudi Arabia. The Arab country has experienced the most significant increase in per capita greenhouse gas emissions since 1990, now leading the world at 22.8 metric tons of carbon dioxide equivalent per capita.

Visual Capitalist shows the top 50 countries by central bank reserves

As of 2024, China, Japan, and the United States held the top three spots in terms of the value of their respective central bank reserves.

As of 2022, China has the largest reserve of rare earth elements

At 37.9% of estimated global reserves, China possesses twice the amount of REEs as Vietnam, the next closest nation. REEs, or lanthanides, are a set of 17 elements on the periodic table, which, alongside scandium and yttrium, share similar chemical properties that make them difficult to separate from within ores.

The countries with the highest wealth per person, ranked

When looking at countries with the highest average wealth per person, the United States comes in at number three (with $564,862 per person). But the US doesn't even make the top 10 when looking at the median wealth per person rather than the average, which is perhaps a more accurate version of the data. Explore the numbers here.

See how global nuclear arsenals surged—then shrank—by country since 1945

Worldwide nuclear stockpiles peaked at over 60,000 warheads in the mid‑1980s during the US-Soviet arms race. Today, about nine nations collectively maintain roughly 12,000 warheads, with Russia and the US still holding the majority.

Learn how aquifers and wells provide the largest reserves of accessible freshwater on Earth

Roughly a third of Earth's freshwater is stored underground in aquifers—permeable and porous rock formations where water naturally flows from the Earth's surface and accumulates. About half of this groundwater is accessed through wells, a feat of engineering used for thousands of years.

The widespread need for rechargeable batteries has fueled surging lithium demand

As of 2025, the average person uses 27 times more mined lithium than they did in the 1990s, with the US ranking second globally in consumption despite producing less than 1% of global supply. However, potential alternative materials and boom-and-bust cycles have challenged the profitability of mines and future demand for the mineral.

Gulf nations produce about 40% of the world's desalinated water

According to a 2023 report, six Gulf states produced 1.9 trillion gallons of freshwater across more than 400 desalination plants along their coasts. These plants create water suitable for human consumption by boiling saltwater and collecting steam or using high-pressure pumps to push seawater through a filter that only allows water molecules through.

As of 2026, the majority of US states have unsafe radon exposure levels

Alaska, South Dakota, Pennsylvania, Ohio, and Washington top the list of states with exposure levels above 4 picocuries per liter for this naturally occurring radioactive gas.
