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 Solar Energy is Consumed Per Capita? (1965-2019)

This visualization highlights the growth in solar energy consumption per capita over 54 years. Which countries are leading the way?

How Much Solar Energy is Consumed Per Capita?

The long history of solar energy use dates as far back as 4,000 B.C.—when ancient civilizations would use solar architecture to design dwellings that would use more of the sun’s warmth in the winter, while reducing excess heat in the summer.

But despite its long history, we’ve only recently started to rely on solar energy as a renewable power source. This Our World in Data visualization pulls data from BP’s Statistical Review of World Energy to highlight how solar energy consumption per capita has grown in countries around the world over 54 years.

Solar Success: The Top Consumers Per Capita

Solar energy consumption is measured in kilowatt hours (kWh)—and as of the latest estimates, Australia leads the world in terms of highest solar energy consumption per capita at 1,764 kWh in 2019. A combination of factors help achieve this:

  • Optimal weather conditions
  • High gross domestic product (GDP) per capita
  • Tariffs incentivizing the shift to solar

In fact, government subsidies such as financial assistance with installation and feed-in tariffs help bring down the costs of residential solar systems to a mere AUD$1 (US$0.70) per watt.

#10🇪🇸 Spain7972.34%

Source: Our World in Data, BP Statistical Review of World Energy 2020
Note that some conversions have been made for primary energy consumption values from Gigajoules (GJ) to kWh.

Coming in second place, Japan has the highest share of solar (3.59%) compared to its total primary energy consumption per capita. After the Fukushima nuclear disaster in 2011, the nation made plans to double its renewable energy use by 2030.

Japan has achieved its present high rates of solar energy use through creative means, from repurposing abandoned golf courses to building floating “solar islands”.

Solar Laggards: The Bottom Consumers Per Capita

On the flip side, several countries that lag behind on solar use are heavily reliant on fossil fuels. These include several members of OPEC—Iraq, Iran, and Venezuela—and former member state Indonesia.

This reliance may also explain why, despite being located in regions that receive the most annual “sunshine hours” in the world, this significant solar potential is yet unrealized.

Interestingly, Iceland is on this list for a different reason. Although the country still relies on renewable energy, it gets this from different sources than solar—a significant share comes from hydropower as well as geothermal power.

The Future of Solar

One thing the visualization above makes clear is that solar’s impact on the global energy mix has only just begun. As the costs associated with producing solar power continue to fall, we’re on a steady track to transform solar energy into a more significant means of generating power.

All in all, with the world’s projected energy mix from total renewables set to increase over 300% by 2040, solar energy is on a rising trend upwards.

Mapped: The World’s Largest State-Owned Oil Companies

State-owned oil companies control roughly three-quarters of global oil supply. See how these companies compare in this infographic.

Mapped: The World’s Largest State-Owned Oil Companies

Oil is one of the world’s most important natural resources, playing a critical role in everything from transportation fuels to cosmetics.

For this reason, many governments choose to nationalize their supply of oil. This gives them a greater degree of control over their oil reserves as well as access to additional revenue streams. In practice, nationalization often involves the creation of a national oil company to oversee the country’s energy operations.

What are the world’s largest and most influential state-owned oil companies?

Editor’s Note: This post and infographic are intended to provide a broad summary of the state-owned oil industry. Due to variations in reporting and available information, the companies named do not represent a comprehensive index.

State-Owned Oil Companies by Revenue

National oil companies are a major force in the global energy sector, controlling approximately three-quarters of the Earth’s oil reserves.

As a result, many have found their place on the Fortune Global 500 list, a ranking of the world’s 500 largest companies by revenue.

CountryNameFortune Global 500 Rank2019 Revenues

China is home to the two largest companies from this list, Sinopec Group and China National Petroleum Corporation (CNPC). Both are involved in upstream and downstream oil operations, where upstream refers to exploration and extraction, and downstream refers to refining and distribution.

It’s worth noting that many of these companies are listed on public stock markets—Sinopec, for example, trades on exchanges located in Shanghai, Hong Kong, New York, and London. Going public can be an effective strategy for these companies as it allows them to raise capital for new projects, while also ensuring their governments maintain control. In the case of Sinopec, 68% of shares are held by the Chinese government.

Saudi Aramco was the latest national oil company to follow this strategy, putting up 1.5% of its business in a 2019 initial public offering (IPO). At roughly $8.53 per share, Aramco’s IPO raised $25.6 billion, making it one of the world’s largest IPOs in history.

Geopolitical Tensions

Because state-owned oil companies are directly tied to their governments, they can sometimes get caught in the crosshairs of geopolitical conflicts.

The disputed presidency of Nicolás Maduro, for example, has resulted in the U.S. imposing sanctions against Venezuela’s government, central bank, and national oil company, Petróleos de Venezuela (PDVSA). The pressure of these sanctions is proving to be particularly damaging, with PDVSA’s daily production in decline since 2016.

State-Owned Oil Companies - Venezuela example

In a country for which oil comprises 95% of exports, Venezuela’s economic outlook is becoming increasingly dire. The final straw was drawn in August 2020 when the country’s last remaining oil rig suspended its operations.

Other national oil companies at the receiving end of American sanctions include Russia’s Rosneft and Iran’s National Iranian Oil Company (NIOC). Rosneft was sanctioned by the U.S. in 2020 for facilitating Venezuelan oil exports, while NIOC was targeted for providing financial support to Iran’s Islamic Revolutionary Guard Corps, an entity designated as a foreign terrorist organization.

Climate Pressures

Like the rest of the fossil fuel industry, state-owned oil companies are highly exposed to the effects of climate change. This suggests that as time passes, many governments will need to find a balance between economic growth and environmental protection.

Brazil has already found itself in this dilemma as the country’s president, Jair Bolsonaro, has drawn criticism for his dismissive stance on climate change. In June 2020, a group of European investment firms representing $2 trillion in assets threatened to divest from Brazil if it did not do more to protect the Amazon rainforest.

These types of ultimatums may be an effective solution for driving climate action forward. In December 2020, Brazil’s national oil company, Petrobras, pledged a 25% reduction in carbon emissions by 2030. When asked about commitments further into the future, however, the company’s CEO appeared to be less enthusiastic.

That’s like a fad, to make promises for 2050. It’s like a magical year. On this side of the Atlantic we have a different view of climate change.

— Roberto Castello Branco, CEO, Petrobras

With its 2030 pledge, Petrobras joins a growing collection of state-owned oil companies that have made public climate commitments. Another example is Malaysia’s Petronas, which in November 2020, announced its intention to achieve net-zero carbon emissions by 2050. Petronas is wholly owned by the Malaysian government and is the country’s only entry on the Fortune Global 500.

Challenges Lie Ahead

Between geopolitical conflicts, environmental concerns, and price fluctuations, state-owned oil companies are likely to face a much tougher environment in the decades to come.

For Petronas, achieving its 2050 climate commitments will require significant investment in cleaner forms of energy. The company has been involved in numerous solar energy projects across Asia and has stated its interests in hydrogen fuels.

Elsewhere, China’s national oil companies are dealing with a more near-term threat. In compliance with an executive order issued by the Trump Administration in November 2020, the New York Stock Exchange (NYSE) announced it would delist three of China’s state-run telecom companies. Analysts believe oil companies such as Sinopec could be delisted next, due to their ties with the Chinese military.
