Press play above to watch how per capita solar energy consumption increases over 54 years.

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.

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.

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
Bitcoin network -129 
Norway5.4M124
Bangladesh165.7M70
Google-12
Facebook-5
Walt Disney World Resort (Florida)-1

Note: A terawatt hour (TWh) is a measure of electricity that represents 1 trillion watts sustained for one hour.

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.

Natural gas38%33%17%44%

Solar12%13%17%17%
Geothermal8%0%0%6%

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.

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 
🇨🇳 ChinaSinopec Group2$443B
🇨🇳 ChinaChina National Petroleum Corporation (CNPC) 4$379B
🇸🇦 Saudi ArabiaSaudi Aramco6$330B

🇻🇪 Venezuela Petróleos de Venezuela (PDVSA)Not listed$23B (2018)

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.
