The pandemic brought strong headwinds for the oil and gas industry, and oil majors felt the blow.
Global primary energy consumption fell by 4.5% relative to 2019 and oil demand declined by 9%. For a brief period in April 2020, the price of West Texas Intermediate (WTI) crude futures went subzero, marking the largest one-day price plunge since 1983.
Some expected the demand crash to have a lasting impact on the industry, but it’s safe to say that 2021 has proved otherwise.
Oil Resurfaces as Energy Crisis Deepens
The world is facing a shortage of energy, and peak winter is yet to hit most parts of the globe.
Pandemic-induced supply restraints from producers, in addition to rising energy demand from recovering economies, have sent nations scrambling for petroleum products. Consequently, oil prices are resurfacing to pre-pandemic levels.
As of today, prices of WTI crude futures are at their highest levels in the last five years at over $80 per barrel. Furthermore, U.S. natural gas prices hit a 7-year high of $6.5 per million British thermal units (BTU) earlier this month. Elsewhere, European benchmark natural gas futures have surged 1,300% since May 2020.
Of course, the largest oil and gas companies are riding this wave of resurgence. Using data from CompaniesMarketCap.com, the above infographic ranks the top 20 oil and gas companies by market cap as of October 7, 2021.
Big Oil: The Largest Oil and Gas Companies by Market Cap
Given that we often see their logos at gas stations, the largest oil and gas companies are generally quite well-known. Here’s how they stack up by market cap:
Rank | Company | Market Cap* (US$, billions) | Country |
---|---|---|---|
1 | Saudi Aramco | $1,979 | Saudi Arabia 🇸🇦 |
2 | ExxonMobil | $257.30 | U.S. 🇺🇸 |
3 | Chevron | $205.29 | U.S. 🇺🇸 |
4 | Shell | $175.28 | Netherlands 🇳🇱 |
5 | PetroChina | $162.55 | China 🇨🇳 |
6 | TotalEnergies | $130.56 | France 🇫🇷 |
7 | Gazprom | $121.77 | Russia 🇷🇺 |
8 | ConocoPhillips | $95.93 | U.S. 🇺🇸 |
9 | BP | $93.97 | U.K. 🇬🇧 |
10 | Rosneft | $84.07 | Russia 🇷🇺 |
11 | Equinor | $83.60 | Norway 🇳🇴 |
12 | Enbridge | $82.82 | Canada 🇨🇦 |
13 | Sinopec | $80.48 | China 🇨🇳 |
14 | Novatek | $79.18 | Russia 🇷🇺 |
15 | Duke Energy | $78.08 | U.S. 🇺🇸 |
16 | Petrobras | $69.91 | Brazil 🇧🇷 |
17 | Southern Company | $66.64 | U.S. 🇺🇸 |
18 | Lukoil | $64.70 | Russia 🇷🇺 |
19 | CNOOC | $52.04 | China 🇨🇳 |
20 | Enterprise Products | $50.37 | U.S. 🇺🇸 |
*As of October 7, 2021.
Saudi Aramco is one of the five companies in the trillion-dollar club as the world’s third-largest company by market cap. Its market cap is nearly equivalent to the combined valuation of the other 19 companies on the list. But what makes this figure even more astounding is the fact that the company went public less than two years ago in December 2019.
However, the oil giant’s valuation doesn’t come out of the blue. Aramco was the world’s most profitable company in 2019, raking in $88 billion in net income. Apple took this title in 2020, but high oil prices could propel Aramco back to the top in 2021.
Although Standard Oil was split up a century ago, its legacy lives on today in the form of Big Oil. ExxonMobil and Chevron—the second and third-largest companies on the list—are direct descendants of Standard Oil. Furthermore, Shell and BP both acquired assets from Standard Oil’s original portfolio on the road to becoming global oil giants.
The geographical distribution of the largest oil and gas companies shows how global the industry is. The top 20 oil and gas companies come from 10 different countries. The U.S. hosts six of them, while four are headquartered in Russia. The other 10 are located in one of China, Brazil, Saudi Arabia, or Europe.
Big Oil, Bigger Emissions
Due to the nature of fossil fuels, the biggest oil and gas companies are also among the biggest greenhouse gas (GHG) emitters.
In fact, Saudi Aramco is the world’s largest corporate GHG emitter and accounts for over 4% of the entire world’s emissions since 1965. Chevron, Gazprom, ExxonMobil, BP, and several other oil giants join Aramco on the list of top 20 GHG emitters between 1965 and 2017.
Shifting towards a low-carbon future will undoubtedly require the world to rely less on fossil fuels. But completely shunning the oil and gas industry isn’t possible at the moment, as shown by the global energy crisis.

Energy independence is top of mind for many nations as Russia’s invasion of Ukraine has prompted sanctions and bans against Russian coal and crude oil imports.
Despite being the world’s largest oil producer, in 2021 the U.S. still imported more than 3 billion barrels of crude oil and petroleum products, equal to 43% of the country’s consumption.
This visualization uses data from the Energy Information Administration (EIA) to compare U.S. crude oil and refined product imports with domestic crude oil production, and breaks down which countries the U.S. imported its oil from in 2021.
U.S. Crude Oil Imports, by Country
The U.S. imports more than 8 million barrels of petroleum products a day from other nations, making it the world’s second-largest importer of crude oil behind China.
America’s northern neighbor, Canada, is the largest source of petroleum imports at 1.58 billion barrels in 2021. These made up more than 51% of U.S. petroleum imports, and when counting only crude oil imports, Canada’s share rises to 62%.
Rank | Country | U.S. Oil Imports (2021, in barrels) | Share |
---|---|---|---|
#1 | 🇨🇦 Canada | 1,584 million | 51.3% |
#2 | 🇲🇽 Mexico | 259 million | 8.4% |
#3 | 🇷🇺 Russia | 254 million | 7.9% |
#4 | 🇸🇦 Saudi Arabia | 156 million | 5.1% |
#5 | 🇨🇴 Colombia | 74 million | 2.4% |
#6 | 🇪🇨 Ecuador | 61 million | 2.0% |
#7 | 🇮🇶 Iraq | 57 million | 1.9% |
#8 | 🇧🇷 Brazil | 52 million | 1.7% |
#9 | 🇰🇷 South Korea | 48 million | 1.6% |
#10 | 🇳🇱 Netherlands | 46 million | 1.5% |
#11 | 🇳🇬 Nigeria | 45 million | 1.5% |
Other countries | 459 million | 14.7% | |
Total | 3,091 million | 100.0% |
The second-largest contributor to U.S. petroleum imports was another neighbor, Mexico, with 259 million barrels imported in 2021—making up a bit more than 8% of U.S. petroleum imports.
Russia was the third-largest exporter of crude oil and petroleum products to the U.S. in 2021, with their 254 million barrels accounting for almost 8% of total imports.
U.S. Crude Oil and Petroleum Imports from OPEC and OPEC+
Only about 11% of U.S. crude oil and petroleum product imports come from OPEC nations, with another 16.3% coming from OPEC+ members.
While imports from OPEC and OPEC+ members make up more than a quarter of America’s total petroleum imports, this share is fairly small when considering OPEC members currently control nearly 80% of the world’s oil reserves.
Which Countries are Part of OPEC and OPEC-Plus?
The Organization of Petroleum Exporting Countries (OPEC) is a group of 13 petroleum producing nations that formed in 1960 to provide steady prices and supply distribution of crude oil and petroleum products.
In 2016, OPEC-plus was formed with additional oil-exporting nations in order to better control global oil supply and markets in response to a deluge of U.S. shale supply hitting the markets at that time.
OPEC members:
- 🇮🇷 Iran*
- 🇮🇶 Iraq*
- 🇰🇼 Kuwait*
- 🇸🇦 Saudi Arabia*
- 🇻🇪 Venezuela*
- 🇩🇿 Algeria
- 🇦🇴 Angola
- 🇬🇶 Equatorial Guinea
- 🇬🇦 Gabon
- 🇱🇾 Libya
- 🇳🇬 Nigeria
- 🇨🇩 Republic of the Congo
- 🇦🇪 United Arab Emirates
* Founding members
OPEC+ members:
- 🇷🇺 Russia
- 🇲🇽 Mexico
- 🇰🇿 Kazakhstan
- 🇲🇾 Malaysia
- 🇦🇿 Azerbaijan
- 🇧🇭 Bahrain
- 🇧🇳 Brunei
- 🇴🇲 Oman
- 🇸🇩 Sudan
- 🇸🇸 South Sudan
Although OPEC and OPEC+ members supply a significant part of U.S. crude oil and petroleum imports, America has avoided overdependence on the group by instead building strong ties with neighboring exporters Canada and Mexico.
Crude Oil Imports Capitalize on U.S. Refineries
While the U.S. has been a net exporter of crude oil and petroleum products the past two years, exporting 3.15 billion barrels while importing 3.09 billion barrels in 2021, crude oil-only trade tells a different story.
In terms of just crude oil trade, the U.S. was a significant net importer, with 2.23 billion barrels of crude oil imports and only 1.08 billion barrels of crude oil exports. But with the U.S. being the world’s largest crude oil producer, why is this?
As noted earlier, neighboring Canada makes up larger shares of U.S. crude oil imports compared to crude oil and petroleum product imports. Similarly, Mexico reaches 10% of America’s crude oil imports when excluding petroleum products.
Maximizing imports from neighboring countries makes sense on multiple fronts for all parties due to lower transportation costs and risks, and it’s no surprise Canada and Mexico are providing large shares of just crude oil as well. With such a large collection of oil refineries across the border, it’s ultimately more cost-efficient for Canada and Mexico to tap into U.S. oil refining rather than refining domestically.
In turn, Mexico is the largest importer of U.S. produced gasoline and diesel fuel, and Canada is the third-largest importer of American-produced refined petroleum products.
Replacing Russian Crude Oil Imports
While Russia only makes up 8% of American petroleum product imports, their 254 million barrels will need to be replaced as both countries ceased trading soon after Russia’s invasion of Ukraine.
In an effort to curb rising oil and gasoline prices, in March President Joe Biden announced the release of up to 180 million barrels from the U.S. Strategic Petroleum Reserves. Other IEA nations are also releasing emergency oil reserves in an attempt to curb rising prices at the pump and volatility in the oil market.
While the U.S. and the rest of the world are still managing the short-term solutions to this oil supply gap, the long-term solution is complex and has various moving parts. From ramping up domestic oil production to replacing oil demand with other cleaner energy solutions, oil trade and imports will remain a vital part of America’s energy supply.

Wind and solar generate over a tenth of the world’s electricity. Taken together, they are the fourth-largest source of electricity, behind coal, gas, and hydro.
This infographic based on data from Ember shows the rise of electricity from these two clean sources over the last decade.
Europe Leads in Wind and Solar
Wind and solar generated 10.3% of global electricity for the first time in 2021, rising from 9.3% in 2020, and doubling their share compared to 2015 when the Paris Climate Agreement was signed.
In fact, 50 countries (26%) generated over a tenth of their electricity from wind and solar in 2021, with seven countries hitting this landmark for the first time: China, Japan, Mongolia, Vietnam, Argentina, Hungary, and El Salvador.
Denmark and Uruguay achieved 52% and 47% respectively, leading the way in technology for high renewable grid integration.
Rank | Top Countries | Solar/Wind Power Share |
---|---|---|
#1 | 🇩🇰 Denmark | 51.9% |
#2 | 🇺🇾 Uruguay | 46.7% |
#3 | 🇱🇺 Luxembourg | 43.4% |
#4 | 🇱🇹 Lithuania | 36.9% |
#5 | 🇪🇸 Spain | 32.9% |
#6 | 🇮🇪 Ireland | 32.9% |
#7 | 🇵🇹 Portugal | 31.5% |
#8 | 🇩🇪 Germany | 28.8% |
#9 | 🇬🇷 Greece | 28.7% |
#10 | 🇬🇧 United Kingdom | 25.2% |
From a regional perspective, Europe leads with nine of the top 10 countries. On the flipside, the Middle East and Africa have the fewest countries reaching the 10% threshold.
Further Renewables Growth Needed to meet Global Climate Goals
The electricity sector was the highest greenhouse gas emitting sector in 2020.
According to the International Energy Agency (IEA), the sector needs to hit net zero globally by 2040 to achieve the Paris Agreement’s goals of limiting global heating to 1.5 degrees. And to hit that goal, wind and solar power need to grow at nearly a 20% clip each year to 2030.
Despite the record rise in renewables, solar and wind electricity generation growth currently doesn’t meet the required marks to reach the Paris Agreement’s goals.
In fact, when the world faced an unprecedented surge in electricity demand in 2021, only 29% of the global rise in electricity demand was met with solar and wind.
Transition Underway
Even as emissions from the electricity sector are at an all-time high, there are signs that the global electricity transition is underway.
Governments like the U.S., Germany, UK, and Canada are planning to increase their share of clean electricity within the next decade and a half. Investments are also coming from the private sector, with companies like Amazon and Apple extending their positions on renewable energy to become some of the biggest buyers overall.
More wind and solar are being added to grids than ever, with renewables expected to provide the majority of clean electricity needed to phase out fossil fuels.
