For most of the 20th century, oil supermajors defined themselves purely as fossil fuel companies. ExxonMobil, Chevron, BP, Shell, and TotalEnergies built vast global empires extracting, refining, and selling petroleum products. Today, they face an existential question: can they transform themselves into diversified energy companies before the energy transition erodes their core business?
The answer, watching how these companies have behaved over the past decade, is: "it's complicated." There have been ambitious pledges, significant investments in solar and wind, and genuine strategic pivots — but also quiet retreats, greenwashing accusations, and a return to fossil fuel emphasis driven by energy security concerns and shareholder pressure for returns.
The European vs American Divide
The most striking pattern in Big Oil's renewable energy response is the sharp divergence between European and American supermajors. BP, Shell, and TotalEnergies have pursued renewable energy investments far more aggressively than ExxonMobil and Chevron — reflecting different regulatory environments, investor expectations, and corporate cultures.
BP — The Most Aggressive Pivot (Then a Retreat)
Under CEO Bernard Looney (2020-2023), BP made the most radical public commitment to energy transition of any supermajor — pledging to cut oil and gas production 40% by 2030 and invest heavily in offshore wind, solar, and EV charging. The market punished the stock relative to US peers, who continued returning more cash to shareholders. By 2023, BP under new CEO Murray Auchincloss walked back many targets — the 40% production cut became 25%, offshore wind ambitions were scaled back. BP remains more focused on transition than ExxonMobil but has pulled back from its 2020 ambitions.
Shell — Balanced Portfolio Approach
Shell has built one of the largest EV charging networks in the world (Shell Recharge), invested in LNG as a "bridge fuel," and developed significant renewable power generation assets. However, Shell also won a landmark UK North Sea drilling license in 2023 and continues significant fossil fuel investment. In 2021, a Dutch court ordered Shell to cut emissions 45% by 2030 — a ruling Shell has appealed. Shell's approach is to be a "broad energy company" rather than transitioning away from oil and gas.
TotalEnergies — The Integrated Energy Vision
France's TotalEnergies has arguably made the most coherent transition strategy among the majors, renaming itself from Total to emphasize this vision. The company has become one of the world's largest solar and wind developers, targets 35% of energy sales from low-carbon sources by 2030, and has maintained its oil and gas business to fund the transition. CEO Patrick Pouyanné argues that the transition requires oil revenue to finance the renewables buildout — a controversial but financially rational position.
ExxonMobil — Doubling Down on Oil and Gas
ExxonMobil has been the most skeptical of the energy transition majors. Rather than pivoting to renewables, Exxon has focused on becoming the lowest-cost producer of oil and gas, arguing that fossil fuel demand will remain robust for decades and that renewables investments would destroy shareholder value. Exxon's major strategic bet on clean energy is carbon capture and sequestration (CCS), where it is the industry's largest investor — a technology that extends the life of fossil fuels rather than replacing them.
Saudi Aramco — A Different Kind of Transition
Saudi Aramco, the world's largest oil company by production, has a distinctly different transition strategy: maximize production of the cheapest and lowest-carbon-intensity oil (Saudi conventional crude has a very low production carbon footprint per barrel) while investing in blue hydrogen and carbon capture. The company argues that the world will need its low-cost, low-emission-intensity oil well into the energy transition and that stranded asset risk is minimal for barrels that cost $3-4 to produce.
"Every dollar we invest in renewables is a dollar not invested in oil and gas that the world still needs. The question is the pace of transition, not the direction." — Energy industry perspective
Where Are Renewables Investments Actually Going?
Looking at actual capital allocation rather than press releases, Big Oil's renewable spending remains modest relative to total capex. According to Wood Mackenzie data, the five largest oil supermajors allocated approximately 15-25% of their capital expenditure to low-carbon investments in 2022-23 — up from virtually zero in 2015, but still dominated by fossil fuel investment.
The renewable investments that have proceeded most successfully are those in sectors adjacent to existing oil and gas businesses: LNG (liquefied natural gas), where companies leverage existing trading, shipping, and project management expertise; carbon capture and storage, which uses geological expertise and can be bolted onto existing industrial sites; and offshore wind, where subsea engineering skills from deepwater oil transfer usefully.
Pure solar and wind generation has proven more difficult for oil majors to compete in. These businesses require different skills (power trading, grid management, regulatory relationships with utilities regulators) and offer lower returns — typically 6-8% unlevered returns vs. 12-15% for top-tier oil projects — making the capital allocation math challenging for companies facing activist shareholders demanding oil-like returns.
The Greenwashing Question
Several major oil companies have faced legal challenges and regulatory scrutiny over their climate messaging. The UK's Advertising Standards Authority banned Shell and BP advertisements for misleading renewable energy claims. Multiple cities and states have sued ExxonMobil for allegedly knowingly misleading the public about climate science. The EU's "green claims" directive, coming into force by 2026, will impose strict standards on corporate environmental marketing.
The most persistent criticism is that companies announce headline-grabbing net-zero targets while their actual capital expenditure plans imply continued fossil fuel growth. The IEA found in its Net Zero by 2050 report that no new oil and gas fields should be approved for development after 2021 in a path consistent with 1.5°C warming. Major oil companies continue approving new projects.
What the Energy Transition Actually Requires from Oil Majors
A coherent view of what the energy transition needs from the oil industry involves two seemingly contradictory things simultaneously: continued investment in existing low-cost oil and gas fields to meet near-term demand without price spikes, while rapidly scaling down new long-cycle investment in high-cost reserves that won't produce for 10+ years and may not be needed.
The oil majors most likely to succeed through the transition are those that can: produce remaining demand at low cost and carbon intensity; pivot capital allocation toward genuinely competitive clean energy businesses where their skills add value; return surplus capital to shareholders rather than investing in stranded assets; and build the cultural and technical competencies for an energy system where their core skills in project management, trading, and large-scale engineering remain valuable even as fuels change.
Whether any of the current oil supermajors will successfully make this transition remains genuinely uncertain. History suggests that industry incumbents rarely lead the transitions that disrupt their core businesses. The most likely long-term scenario is significant consolidation in the oil industry combined with the emergence of new energy companies — and possibly the disappearance of some current giants — as the energy system reorganizes around lower-carbon fuels.
