25 Largest Energy Companies by Market Cap

In the article, we discuss the 25 largest energy companies according to their market capitalization. You can skip the industry analysis and go directly to the 10 Largest Energy Companies In the World.

The energy sector is a $6 trillion industry that employed around 6.8 million people in the United States in 2022. The energy industry can be divided into two major subgroups, non-renewable or conventional energy, and renewable energy. The non-renewable energy sector includes petroleum and gas products, nuclear, and coal. Renewable energy sources include wind power generation, biofuels, hydroelectric power, and solar power.

Conventional Energy Market

In 2022, conventional energy with the exception of nuclear energy accounted for 85% of the global energy supply. According to a report by McKinsey, the global coal demand reached its peak in 2013 and saw a rise in demand again in 2021. However, it is expected to go in the downward direction from then onwards. Additionally, International Energy Agency (IEA) believes that electricity production from coal in the United States will reduce from 20% in 2022 to 17% in 2024.

When it comes to fossil fuels, oil, and natural gas are the most commonly used sources of energy. According to IEA, the global oil demand is expected to rise by 1.9 million barrels a day to a record 101.7 million barrels a day. The most significant demand will be seen by jet fuel at 840,000 barrels of oil per day. McKinsey believes that the global oil demand is expected to peak between 2023 and 2025. However, it will be 35% to 50% lower by 2050 due to the global transition toward renewable energy sources. A significant decline in demand is expected to be caused by the rise in electric vehicles, which according to IEA will account for 60% of new car sales by 2030.

According to the IEA, the global gas demand was 87.9 billion cubic feet per day. The McKinsey report states that it will grow by 10%-20% by 2035 and will likely experience a decline afterward.

Currently, the global market leaders in the conventional energy market are Exxon Mobil Corporation (NYSE:XOM), Chevron Corporation (NYSE:CVX), and Shell plc (NYSE:SHEL).

Effects of the Russian Invasion of Ukraine on the Conventional Energy Market

The Russian invasion of Ukraine was one of the most significant events that created uncertainty in the global conventional energy market as a huge part of Europe has been dependent on Russian fuel. The invasion led to the US President Joe Biden issuing an executive order to ban Russian imports and the United Kingdom took the same route. Due to the European Union's dependency on Russian fossil fuels, it did not cut off the imports entirely but decided to reduce them by around two-thirds, mostly due to Germany and Netherlands' reluctance. In 2021, Russia accounted for 13% of the global crude oil supply and 45% of the global natural gas imports, along with 40% of the European Union's demand. On top of that, the country was also responsible for almost 18% of global coal imports.

The aforementioned series of decisions led the global supply of fossil fuels to fall and demand to rise significantly. Consequently, crude oil prices went skyrocketing to $110 per barrel in March 2022 from $76 at the beginning of the year. For 2023, S&P Global forecasted that the global oil supply and demand will start to balance out. However, the effects of cutting off Russian oil had more severe repercussions than expected and the global market will take a few years to return to normal levels. The firm expects the growth to be slower in 2023 than in 2022 at 1.7 million barrels per day compared to the prior year's 4.5 million barrels per day. Nevertheless, the prices of fuel commodities are expected to alleviate over the year.

Renewable Energy Market

According to Allied Market Research, the global renewable energy market was worth $881.7 billion in 2020 and is expected to grow at a CAGR of 8.4% to almost $2 trillion by 2030. The previously mentioned McKinsey report states that due to the move towards renewable energy and decarbonization, the energy sector is expected to grow by 4% per annum and annual supply and production investments are most likely to reach $1.5 trillion to $1.6 by 2035.

Toward the decarbonization of the energy mix, electrification is considered the first step. Electricity generation through wind, solar, and hydrogen power is expected to account for almost 50% of the global power mix by 2035 and then increase to 85% by 2050. Moreover, among the renewable energy sources, green hydrogen is expected to cover 28% of the global power demand by the end of the forecasted period. In the article, we previously mentioned the fall in electricity production from coal. The IEA expects that to be counteracted by renewable energy sources as they rise from 22% in 2022 to 24% in 2024.

With the growing demand for renewable energy, even the big players in the conventional energy market are making a shift toward it. Even the oil supermajors have started to invest in renewable energy projects with BP p.l.c. (NYSE:BP) becoming the first one among them to invest a noteworthy amount.

At the moment the companies aiming toward becoming the global renewable energy giants include NextEra Energy, Inc. (NYSE:NEE), Enbridge Inc. (NYSE:ENB), and Duke Energy Corporation (NYSE:DUK) along with several others.
