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.

Visualizing U.S. Greenhouse Gas Emissions by Sector
The U.S. emits about 6 billion metric tons of greenhouse gases a year. Here’s how these emissions rank by sector.


Visualizing U.S. Emissions by Sector
Decarbonization efforts in the U.S. are ramping up, and in 2020, greenhouse gas (GHG) emissions were lower than at any point during the previous 30 years.
However there’s still work to be done before various organizations, states, and nationwide targets are met. And when looking at GHG emissions by sector, the data suggests that some groups have more work cut out for them than others.
This graphic from the National Public Utilities Council provides the key data and trends on the total emissions by U.S. sector since 1990.
The Highest Emitting Sectors
Collectively, the U.S. emitted 5,981 million metric tons (MMT) of CO2-equivalent (CO2e) emissions in 2020, which rose 6.1% in 2021.
Here’s how the various sectors in the U.S. compare.
Sector | 2020 GHG emissions, MMT CO2e | Percentage of Total |
---|---|---|
Transportation | 1,627.6 | 27% |
Electricity generation | 1,482.6 | 25% |
Industry | 1,426.2 | 24% |
Agriculture | 635.1 | 11% |
Commercial | 425.3 | 7% |
Residential | 362.0 | 6% |
U.S. territories | 23.0 | <1% |
The transportation sector ranks highest by emissions and has been notably impacted by the COVID-19 pandemic, which is still affecting travel and supply chains. This has led to whipsawing figures during the last two years.
For instance, in 2020, the transportation sector’s emissions fell 15%, the steepest fall of any sector. But the largest increase in emissions in 2021 also came from transportation, which is largely credited to the economic and tourism recovery last year.
Following transportation, electricity generation accounted for a quarter of U.S. GHG emissions in 2020, with fossil fuel combustion making up nearly 99% of the sector’s emissions. The other 1% includes waste incineration and other power generation technologies like renewables and nuclear power, which produce emissions during the initial stages of raw material extraction and construction.
Decarbonizing the Power Sector
The Biden Administration has set a goal to make the U.S. power grid run on 100% clean energy by 2035—a key factor in achieving the country’s goal of net zero emissions by 2050.
Industrial factories, commercial buildings, and homes all consume electricity to power their machinery and appliances. Therefore, the power sector can help reduce their carbon footprint by supplying more clean electricity, although this largely depends on the availability of infrastructure for transmission.
Here’s how sectors would look if their respective electricity end-use is taken into account
Sector | Emissions by Sector % of Total |
---|---|
Agriculture | 11% |
Transportation | 27% |
Industry | 30% |
Residential & Commercial | 30% |
Percentages may not add up to 100% due to independent rounding
With these adjustments, the industrial, commercial, and residential sectors experience a notable jump, and lead ahead of other categories
Today, the bulk of electricity generation, 60%, comes from natural gas and coal-fired power plants, with nuclear, renewables, and other sources making up 40% of the total.
Energy Source | 2020 Electric generation, billion kWh | Share of total |
---|---|---|
Natural Gas | 1,575 | 38.3% |
Coal | 899 | 21.8% |
Nuclear | 778 | 18.9% |
Wind | 380 | 9.2% |
Hydropower | 260 | 6.3% |
However, progress and notable strides have been made towards sustainable energy. In 2021, renewables accounted for one-fifth of U.S. electricity generation, roughly doubling their share since 2010.
Coal’s share as a source of electric power has dropped dramatically in recent years. And partially as a result, electricity generation has seen its portion of emissions successfully decrease by 21% , with overall emissions falling from 1,880 million metric tons of CO2 to 1,482 million metric tons.
How Utilities Can Lead the Way
Should these trends persist, the electricity generation sector has a chance to play a pivotal role in the broader decarbonization initiative. And with the bulk of electricity generation in the U.S. coming from investor-owned utilities (IOUs), this is a unique opportunity for IOUs to lead the transition toward cleaner energy.
The National Public Utilities Council is the go-to resource to learn how utilities can lead in the path towards decarbonization.

In 2011, around 55,000 electric vehicles (EVs) were sold around the world. 10 years later in 2021, that figure had grown close to 7 million vehicles.
With many countries getting plugged into electrification, the global EV market has seen exponential growth over the last decade. Using data from the International Energy Agency (IEA), this infographic shows the explosion in global EV sales since 2011, highlighting the countries that have grown into the biggest EV markets.
The Early EV Days
From 2011 to 2015, global EV sales grew at an average annual rate of 89%, with roughly one-third of global sales occurring in the U.S. alone.
Year | Total EV Sales | CAGR |
---|---|---|
2011 | 55,414 | - |
2012 | 132,013 | 138.2% |
2013 | 220,343 | 66.9% |
2014 | 361,157 | 63.9% |
2015 | 679,235 | 88.0% |
Total sales / Avg growth | 1,448,162 | 89.3% |
In 2014, the U.S. was the largest EV market followed by China, the Netherlands, Norway, and France. But things changed in 2015, when China’s EV sales grew by 238% relative to 2014, propelling it to the top spot.
China’s growth had been years in the making, with the government offering generous subsidies for electrified cars, in addition to incentives and policies that encouraged production. In 2016, Chinese consumers bought more EVs than the rest of the world combined—and the country hasn’t looked back, accounting for over half of global sales in 2021.
EV Sales by Country in 2021
After remaining fairly flat in 2019, global EV sales grew by 38% in 2020, and then more than doubled in 2021. China was the driver of the growth—the country sold more EVs in 2021 than the rest of the world combined in 2020.
Country | 2021 EV Sales | % of Total |
---|---|---|
China 🇨🇳 | 3,519,054 | 51.7% |
U.S. 🇺🇸 | 631,152 | 9.3% |
Germany 🇩🇪 | 695,657 | 10.2% |
France 🇫🇷 | 322,043 | 4.7% |
UK 🇬🇧 | 326,990 | 4.8% |
Norway 🇳🇴 | 153,699 | 2.3% |
Italy 🇮🇹 | 141,615 | 2.1% |
Sweden 🇸🇪 | 138,771 | 2.0% |
South Korea 🇰🇷 | 119,402 | 1.8% |
Netherlands 🇳🇱 | 97,282 | 1.4% |
Rest of Europe 🇪🇺 | 469,930 | 6.9% |
Rest of the World 🌍 | 313,129 | 4.6% |
Total | 6,809,322 | 100.0% |
China has nearly 300 EV models available for purchase, more than any other country, and it’s also home to four of the world’s 10 largest battery manufacturers. Moreover, the median price of electric cars in China is just 10% more than conventional cars, compared to 45-50% on average in other major markets.
Germany, Europe’s biggest auto market, sold nearly 700,000 EVs in 2021, up 72% from 2020. The country hosts some of the biggest EV factories in Europe, with Tesla, Volkswagen, and Chinese battery giant CATL either planning or operating ‘gigafactories’ there. Overall, sales in Europe increased by 65% in 2021, as evidenced by the seven European countries in the above list.
The U.S. also made a comeback after a two-year drop, with EV sales more than doubling in 2021. The growth was supported by a 24% increase in EV model availability, and also by an increase in production of Tesla models, which accounted for half of U.S. EV sales.
Tesla’s Dominance in the U.S.
Tesla is the world’s most renowned electric car company and its dominance in the U.S. is unmatched.
Between 2011 and 2019, Tesla accounted for 40% of all EVs sold in the United States. Furthermore, Tesla cars have been the top-selling EV models in the U.S. in every year since 2015.
EV Model | 2021 Sales | % of 2021 U.S. EV Sales |
---|---|---|
Tesla Model Y* | 185,994 | 29.5% |
Tesla Model 3* | 147,460 | 23.4% |
Ford Mustang Mach-E | 27,140 | 4.3% |
Chevy Bolt EV/EUV | 24,828 | 3.9% |
Volkswagen ID.4 | 16,742 | 2.7% |
Tesla Model S* | 15,545 | 2.5% |
Nissan Leaf | 14,239 | 2.3% |
Porsche Taycan | 9,419 | 1.5% |
Tesla Model X* | 7,985 | 1.3% |
Audi e-tron | 7,429 | 1.2% |

Tesla accounted for over 50% of EV sales in the U.S. in 2021 with the Model Y—launched in 2019—taking the top spot. Furthermore, the Model Y remained the bestselling EV in the first quarter of 2022, with Tesla taking up a massive 75% of the EV market share.
Despite Tesla’s popularity, it could face a challenge as other automakers roll out new models and expand EV production. For example, General Motors aims to make 20 EV models available by 2025, and Ford expects to produce at least 2 million EVs annually by 2026. This increase in competition from incumbents and new entrants could eat away at Tesla’s market share in the coming years.
