Over the last 50 years, the world has seen a colossal increase in energy consumption—and with the ongoing transition to renewable energy, it’s interesting to look at how these sources of energy have been evolving over time.

While some countries continue to rely heavily on fossil fuels like oil, coal, and natural gas, others have integrated alternative energy sources into their mix.

This visualization comes to us from Brian Moore and it charts the evolution of energy consumption in the 64 countries that have data available for all of the last 50 years.

Tera-What? The Most Prominent Sources of Energy (2009-2018)

First, let’s take a look at which sources have produced the most energy over the last decade of data. Energy consumption is measured in terawatt-hours (TWh)—a unit of energy equal to outputting one trillion watts for an hour.

Energy Source% of Total Energy Consumption
(2009-2018)
Sum of Total Energy
(2009-2018) (TWh)
Oil34.3%509,800
Coal29.2%434,300
Gas22.8%339,300
Hydropower6.7%99,200
Nuclear4.6%68,800
Wind1.3%18,700
Geothermal/Biomass/Other0.9%12,700
Solar0.4%5,700
Total100.0%1,389,300 TWh

Looking at this data, it’s clear that fossil fuels have been used much more than alternative sources. A deeper dive into the topic helps explain why.

Fossil Fuels: What the Data Shows

As the predominant source of energy, fossil fuels collectively accounted for a massive 86.2% of total energy consumption over 2009-2018, or roughly 1.2 million TWh. If you’re wondering, that’s enough to power the equivalent of 109 billion U.S. homes with electricity for a year.

Among fossil fuel sources, oil emerges as the clear leader, responsible for 34.3% or 509,800 TWh of energy consumption over 2009-2018. Apart from being the primary fuel for transportation throughout history, oil remains relatively affordable—making it an easy choice for producers and consumers alike.

Closely following oil is coal, which countries rely on for its abundance, low costs, and low infrastructure requirements. Over the last decade of data, 29.2% of total energy came from coal, amounting to a substantial 434,300 TWh.

As a cleaner alternative to coal, natural gas has increased in popularity. Gas accounted for 22.8% or 339,300 TWh of energy consumed between 2009-2018, mainly attributed to its ample supply and affordability.

What About Renewables?

Only 13.8% of energy consumption over 2009-2018 came from renewable or alternative sources of energy, and hydropower accounts for nearly half of it. Why has the use of environmentally-friendly energy sources been so low?

Setting up alternative power plants—especially wind, solar, and nuclear—requires significant capital investment, while facing competition from cheaper and more convenient fossil fuels. The barriers to adopting renewable energy have been weakening, but still remain quite high for low-income countries.

Wind and solar energy were responsible for a mere 1.7% of energy consumption. Compared to fossil fuels like oil and coal, this percentage seems even more minuscule than it does on its own—mainly attributable to the high costs traditionally associated with wind and solar energy.

The Top 10 Countries Relying on Fossil Fuels

Fossil fuels have been the predominant source of energy over the years. After all, 43 of these 64 countries sourced more than 80% of their energy from fossil fuels over 2009-2018.

Here are the ones that come out on top:

Country% of Energy Consumed From Fossil Fuels
(2009-2018)
Most Used Fossil Fuel
(2009-2018)
Oman 🇴🇲100%Gas
Saudi Arabia 🇸🇦100%Oil
Trinidad and Tobago 🇹🇹100%Gas
Kuwait 🇰🇼100%Oil
Qatar 🇶🇦99.9%Gas
United Arab Emirates 🇦🇪99.9%Gas
Hong Kong 🇭🇰99.9%Oil
Algeria 🇩🇿98.8%Gas
Singapore 🇸🇬98.8%Oil
Israel 🇮🇱98.1%Oil

Although it is startling to see that several countries were 100% reliant on fossil fuels, it comes as no surprise that these are countries with abundant reserves of oil or natural gas. Not only are fossil fuels central to certain economies in Middle Eastern and North African (MENA), but they also remain highly affordable for consumers in these places.

On a broader scale, developing and low-income countries are heavily dependent on fossil fuels such as coal for access to cheap electricity and ease of installation.

The Top 10 Countries Using Alternative Energy Sources

The transition to alternative energy sources has been welcomed by many countries, but only a few have prioritized its adoption in the energy mix. Here’s a look at the top 10:

Country% of Energy From Alternative Sources
(2009-2018)
Most Used Alternative Energy Source
(2009-2018)
Iceland 🇮🇸81.6%Hydropower
Norway 🇳🇴67.5%Hydropower
Sweden 🇸🇪65.3%Hydropower
Switzerland 🇨🇭50.5%Hydropower
France 🇫🇷47.0%Nuclear
Finland 🇫🇮39.5%Nuclear
New Zealand 🇳🇿37.2%Hydropower
Brazil 🇧🇷37.2%Hydropower
Canada 🇨🇦34.8%Hydropower
Austria 🇦🇹31.7%Hydropower

Iceland is the only country to have sourced over 80% of its energy from alternative sources over 2009-2018. In general, developed European countries are leading the charge—with Iceland, Norway, Sweden, Switzerland, and France making the top five.

The dominance of hydropower is notable, and so is the lack of wind and solar energy sources. Denmark had the highest percentage of wind energy in its mix, with 14.5%, whereas Italy had the highest percentage of solar, with just 2.4%.

It should be kept in mind that this percentage does not account for population differences. For example, although Italy boasted the highest percentage of solar in its energy mix with 2.4%, China consumed the most amount of energy from solar sources—despite it accounting for only 0.3% of total Chinese energy consumption.

Nevertheless, the costs of solar and wind energy have been falling continuously, and the potential for growth in the renewable energy sector is higher than ever.

The Transition to Renewables: Are We On Track?

Since the Industrial Revolution, fossil fuels have been the primary source of energy worldwide. More recently, the use of renewable energy sources has increased, but not substantially enough.

This predominant reliance on fossil fuels is not doing the transition to renewable energy any favors, but it shines a light on the massive untapped potential for alternative energies, especially in the developing world.

With the prices of renewable energy at record lows and increasing investment flows, the next decade will be a defining one for the global transition to clean energy.

How Much Does the U.S. Depend on Russian Uranium?

How Much Does the U.S. Depend on Russian Uranium?

This was originally posted on Elements. Sign up to the free mailing list to get beautiful visualizations on natural resource megatrends in your email.

The U.S. House of Representatives recently passed a ban on imports of Russian uranium. The bill must pass the Senate before becoming law.

In this graphic, we visualize how much the U.S. relies on Russian uranium, based on data from the United States Energy Information Administration (EIA).

U.S. Suppliers of Enriched Uranium

After Russia invaded Ukraine, the U.S. imposed sanctions on Russian-produced oil and gas—yet Russian-enriched uranium is still being imported.

Currently, Russia is the largest foreign supplier of nuclear power fuel to the United States. In 2022, Russia supplied almost a quarter of the enriched uranium used to fuel America’s fleet of more than 90 commercial reactors.

Most of the remaining uranium is imported from European countries, while another portion is produced by a British-Dutch-German consortium operating in the United States called Urenco.

Similarly, nearly a dozen countries around the world depend on Russia for more than half of their enriched uranium—and many of them are NATO-allied members and allies of Ukraine.

In 2023 alone, the U.S. nuclear industry paid over $800 million to Russia’s state-owned nuclear energy corporation, Rosatom, and its fuel subsidiaries.

It is important to note that 19% of electricity in the U.S. is powered by nuclear plants.

The dependency on Russian fuels dates back to the 1990s when the United States turned away from its own enrichment capabilities in favor of using down-blended stocks of Soviet-era weapons-grade uranium.

As part of the new uranium-ban bill, the Biden administration plans to allocate $2.2 billion for the expansion of uranium enrichment facilities in the United States.
