At the start of the 20th century, a quiet boy in a small French town fell in love with light. Not sunsets or candles, but wires, switches, and the strange new glow of electricity. He believed that if you controlled energy, you could rebuild a country.
That boy was Ernest Mercier’s son to a modest tradesman in Vienne, near Lyon. By the time he was an adult, France had been torn apart by World War I, and his country was desperate for someone who could help it stand on its own feet again.
Mercier had a simple belief that guided his life: "Electricity is civilization in motion." For him, this was not poetry, it was a mission. His obsession with power, first in the form of electricity and later oil, would lead to the creation of the company that eventually became TotalEnergies.
In this story, you’ll see how a curious child became an engineer, how that engineer was asked to secure France’s energy future, how a national project grew into one of the world’s biggest energy companies, and how that company is now trying to shift from crude oil to cleaner power.
From flickering lamps to billion-dollar oil fields, this is how one person’s vision helped power a nation back to life, then reached across the globe.
Ernest Mercier's Early Years: A Spark of Genius
Childhood in Rural France
Ernest Mercier was born in 1878 in Vienne, a riverside town near Lyon. It was a place where factories and farmland sat side by side. You could hear both the clatter of machines and the quiet of the countryside in a single walk.
His father was a modest tradesman. From a young age, Ernest watched machines reshape the world around him. He was drawn to gears, wires, and the invisible forces that made things move. While other children played outside, he was often more interested in how engines turned and why lights stayed on.
That curiosity, patiently focused on how things worked, became the foundation for the rest of his life.
Elite Education and Early Career
Mercier’s talent took him far beyond his small town. He earned a place at École Polytechnique, one of France’s top engineering schools, then continued at École Supérieure d'Électricité, the leading school for electrical engineering.
His professors saw more than a bright student. They saw someone who thought in systems and futures, not just machines. Some of them later said he looked less like a student, and more like a person who would someday help shape the country.
After graduating, he entered the French power industry. At that time, electricity in France was messy and fragmented. Small regional grids, scattered plants, and little coordination.
Mercier quickly stood out. He worked on both hydroelectric and thermal power plants, and by his early 30s he was already managing major projects across the Rhône Valley. He helped bring steady electricity to communities that had never had reliable light after sunset.
He became known as a calm, methodical leader. Colleagues said he spoke less than most, but when he did, people listened. They trusted that if he made a promise about power or timelines, he would keep it.
The Visionary Engineer
By the time World War I erupted, Mercier was not just an engineer who knew his craft. He was already a strategist who understood that energy meant independence.
People around him often described three core traits:
- He spoke less, but achieved more than most.
- He cared more about France’s future than about money or status.
- He saw technology as a tool for freedom, not just profit.
The war would prove him right. When the guns finally fell silent, France’s weakness in energy supply was impossible to ignore. The country needed someone to rebuild its power base from the ground up. That person turned out to be Ernest Mercier.
For more background on his life and career, you can explore the detailed Ernest Mercier biography.
The Call to Rebuild a War‑Torn Nation
France After World War I
World War I left France deeply wounded. Around 1.4 million French soldiers had died. Towns were shattered, railways torn up, and factories either destroyed or barely running.
Even the plants that survived had a deeper problem. They were starved of coal and oil, the fuel that powered every machine. Britain and the United States dominated global oil production, so France, once proud and independent, now had to import energy just to keep lights on and trains moving.
Prime Minister Raymond Poincaré understood the danger. In his view, political freedom meant little if the country had to beg others for oil. Energy dependence was a risk France could not carry again.

Mercier’s Big Opportunity
In 1923, Poincaré turned to Ernest Mercier. By then, Mercier was respected across the electricity sector and had already helped modernize parts of the power grid.
But this time, the task was bigger. Poincaré did not want Mercier to only manage plants. He wanted him to build an oil company that could stand toe‑to‑toe with British and American giants.
The challenge was huge:
- France had almost no meaningful domestic oil reserves.
- The country had very little experience in oil exploration or refining.
- The economy was still shaken after years of war.
Still, Mercier did not hesitate. He later wrote a line that captured his thinking: “A nation that cannot control its own sources of power cannot control its destiny.”
So he started to act. Over the next months, he pulled together a powerful consortium of bankers, industrialists, and engineers. To them, this was more than a business. It was a national project.
The goal was clear. Build a French oil company that could secure supplies for industry and transport, and protect the country from being dependent on others ever again.
If you want to see how the company itself tells these origins, the official TotalEnergies history of its pioneers is a useful companion to this story.
Birth of Compagnie Française des Pétroles (CFP)
Founding in 1924
In March 1924, Ernest Mercier did something many thought was impossible in that climate. He founded Compagnie Française des Pétroles (CFP), backed by 90 banks and major industrial players across France.
This company was born out of need, not greed. France desperately required its own oil supply to keep factories running and to rebuild the economy.
Mercier also negotiated hard with the government to secure France’s 25 percent stake in the Turkish Petroleum Company, a key outcome of the 1920 San Remo Oil Agreement. That stake gave France access to oil fields in Mesopotamia, in what is now Iraq, especially around the rich deposits near Kirkuk.
For the first time, France had a foothold in the global oil race.
Early Challenges and Strategy
CFP’s launch was bold, but the early years were rough. The company had:
- No refineries of its own.
- Limited in‑house drilling experience.
- Powerful rivals like Royal Dutch Shell and British Petroleum surrounding it.
Mercier’s answer was strategy, not size. He believed CFP needed to control every step of the chain. From extraction, to shipping, to refining, to the final sale of fuel. Today we call this vertical integration.
In 1932, CFP opened its first refinery in Normandy. This plant allowed the company to bring in crude oil from the Middle East and turn it into gasoline and other products for France’s rising motor industry.
Those smokestacks in Normandy became a symbol of France’s recovery. Iron towers rising from farmland, showing that the country could rebuild with its own hands.
Key early milestones included:
- Securing Middle Eastern oil through the Turkish Petroleum Company stake.
- Opening the Normandy refinery to process imported crude.
- Beginning to sell products not just in France, but across several continents.
By the early 1930s, CFP was already exploring, refining, and selling oil in multiple regions. What began as a patriotic experiment was turning into a serious contender.
Mercier’s Philosophy
Mercier never saw oil as just another product. To him, it was a cornerstone of national sovereignty.
In a letter to his board, he wrote, "France must not depend on the charity of others for her energy. She must master it herself."
That belief guided every decision he made inside CFP.
Surviving World War II and Riding the Post‑War Boom
Defiance During World War II
The 1930s were tense across Europe, and soon war returned. When World War II broke out and France fell, the German‑backed Vichy regime tried to control many aspects of the economy, including supplies and distribution.
Ernest Mercier was ordered to distribute American Red Cross supplies under Vichy authority. He refused to cooperate. His quiet refusal came at a high price. In 1940, he was forced to step down as chairman of the company he had built.
Despite his departure, CFP survived under new leaders such as Jules Meny, Marcel Chamontin, and later Victor de Metz. The company endured occupation, bombing, and the general collapse of much of France’s industrial base, but it did not disappear.
Victor de Metz and the Expansion Era
When peace returned in 1945, France once again turned to oil as a key tool for rebuilding. Under Victor de Metz, who would lead CFP for about 25 years, the company entered a long phase of expansion.
CFP extended its reach across North Africa, especially into Algeria, which at that time was still a French colony. These fields became another important source of supply.
In 1954, CFP launched a new retail brand: Total. The name was short and confident. It hinted at completeness and modern life. Service stations across France and Africa were repainted in Total’s red, white, and blue. Filling up the car became tied to a sense of French identity.
Total did not stay within Europe and Africa for long. Through Total Petroleum North America Limited, the company moved into the United States and Canada. Within two decades, it owned hundreds of refineries and service stations across both countries.
By the 1980s, the red Total sign had become familiar along highways from Paris to Oklahoma.
Name Changes and Growing Reach
As the company grew, its name evolved to reflect its wider reach:
- 1985: It became Total CFP, combining the heritage of the original CFP with the public strength of the Total brand.
- 1991: It simplified to just Total.
From a country that once depended heavily on imported coal and foreign goodwill, France was now backed by a company that could supply roughly a fifth of its fuel needs.
At this point, the foundation was set for Total to step fully onto the global stage. A good overview of this phase can be found in the TotalEnergies company profile.
From National Dream to Global Powerhouse
Major Mergers and Acquisitions
By the 1990s, Total had grown far beyond its original role as a national safeguard. It now stood alongside giants like Shell, BP, and ExxonMobil.
A big turning point came in 1999, when Total merged with the Belgian oil company Petrofina. The new company was called TotalFina and instantly became a strong European force in refining and distribution.
Then, in 2000, TotalFina acquired another French oil heavyweight, Elf Aquitaine, in a deal worth more than 50 billion dollars. Overnight, TotalFinaElf (as it was then known) became one of the largest integrated oil and gas companies on earth.
In 2003, the company settled on the name Total SA and introduced the now familiar Total globe logo, a colorful sphere that signaled global reach and motion.
Key expansion steps included:
- Launching major exploration projects in Saudi Arabia’s Rub al Khali desert.
- Signing a big refining partnership with Saudi Aramco.
- Moving deeper into natural gas, chemicals, and early alternative energy projects.
If you are interested in how ownership and structure shifted through these phases, the breakdown in who owns TotalEnergies gives more context.
2000s–2010s Growth
By the 2000s and 2010s, Total looked very different from Mercier’s original CFP. It was a global group operating in around 130 countries, employing close to 100,000 people, and managing more than 900 subsidiaries.
The company continued to grow through bold acquisitions:
- 2016: It bought French battery maker Saft Group for 1.1 billion dollars, gaining deeper battery expertise.
- 2016: It acquired Belgian renewable energy supplier Lampiris, gaining more presence in green power retail.
- 2017: It purchased Maersk Oil in a 7.4 billion dollar deal, expanding in the North Sea and strengthening its upstream portfolio.
By 2017, Total SA reported about 171 billion dollars in revenue and 242 billion dollars in assets. It was firmly counted among the world’s seven "super majors" in oil and gas.
A Timeline of a Growing Giant
Here is a brief snapshot of key corporate milestones:
| Year | Milestone |
|---|---|
| 1924 | CFP founded under Ernest Mercier |
| 1932 | First refinery opened in Normandy |
| 1954 | Total retail brand launched |
| 1985 | Name changed to Total CFP |
| 1991 | Name simplified to Total |
| 1999 | Merger with Petrofina to form TotalFina |
| 2000 | Acquisition of Elf Aquitaine |
| 2003 | Name changed to Total SA, globe logo introduced |
From this point on, the question was no longer whether Total could compete. It was how it would adapt to a world that was beginning to demand cleaner energy.
TotalEnergies: A Giant in Transition
Name Change and New Vision
In January 2021, the company changed its name from Total to TotalEnergies SE. This was more than a cosmetic rebrand. It signaled a shift from being mainly an oil and gas company to a broader "multi‑energy" company focused on renewables, electricity, and low‑carbon solutions.
Under CEO Patrick Pouyanné, TotalEnergies began one of the most ambitious transformations any large energy company has attempted. It had to keep supplying the energy the world still used every day, while also building the systems that might replace oil and gas in the future.
The timing was intense. The world was emerging from the pandemic. Energy prices were jumping around. The Russian invasion of Ukraine pushed demand for oil and gas to record levels.
In the middle of all this, TotalEnergies recorded a profit of about 36.2 billion dollars in 2022, about double the year before. At the same time, it was putting billions into wind farms, solar plants, and new technologies.
Investing in the Future While Running the Present
In 2023, TotalEnergies announced plans to invest around 18 billion dollars, including about 5 billion just for low‑carbon projects.
Some of the major projects include:
- The 20.5 billion dollar Mozambique LNG project, focused on liquefied natural gas.
- A planned 30 gigawatt solar and wind complex in India, aimed at serving huge power needs with cleaner sources.
- A growing US renewable energy portfolio in Texas, expected to reach 25 gigawatts of capacity by 2030.
- Heavy investment in carbon capture and storage (CCS), with a goal to capture at least 10 million tons of CO₂ per year by 2030.
- In France, experimental direct air capture projects that use advanced absorbent materials and machine learning to pull CO₂ straight from the air.
Pouyanné summed up the company’s approach in a simple line: "There is no sustainability without profitability." In plain terms, if green projects are not financially sound, they will not last.
TotalEnergies is trying to prove that a company built on crude oil can also succeed in clean power.
Mercier’s Legacy in a Carbon‑Conscious Age
Echoes of the Original Mission
A century after Ernest Mercier began his work, his company is still shaped by his core idea: control your own energy, control your own future.
His original mission was national independence. Today, the mission feels bigger: planetary survival.
TotalEnergies has set several key goals for the coming years:
- Produce and store renewable power on a global scale.
- Capture around 10 million tons of CO₂ each year by 2030.
- Make at least one‑fifth of its operations low‑carbon by 2035.
To support these goals, its research teams are exploring hydrogen, biomass, and next‑generation battery systems. Several refineries are being redesigned as bio‑refineries, which can process sustainable fuels instead of only crude oil.
In more and more regions, solar arrays and offshore wind farms with the TotalEnergies logo are taking the place of traditional oil rigs as the most visible sign of the company’s presence.
For a broad view of this shift, the TotalEnergies overview offers helpful context.
Balancing Profit and Purpose
Pouyanné has been open about a key tension. The world will not stop needing energy. But it has to learn to produce and use that energy more responsibly.
His line captures this: "We are not abandoning oil. We are expanding energy."
That idea fits well with the life story that started in Vienne. Ernest Mercier’s childhood passion for light gave France tools to stand on its own feet. His successors now try to give the world the tools to power itself without breaking the climate.
Would Mercier be proud of how TotalEnergies balances profit and sustainability? Or would he feel the company has drifted from his original vision of independence? That is a question worth asking in any serious conversation about energy.
Conclusion
From a small boy fascinated by electric lamps to a global group investing billions in renewables, this story comes full circle. What began as one engineer’s mission to free France from energy dependence has grown into a company trying to help the world shift to cleaner, smarter power.
Ernest Mercier’s life reminds us that big changes often start with quiet curiosity and a clear purpose. TotalEnergies shows how that purpose can stretch across a century, through wars, mergers, oil booms, and now the push for low‑carbon energy.
What do you think he would say if he could see the company today? Would he see his dream alive in solar farms, LNG plants, and carbon capture labs?
Share your thoughts, keep asking hard questions about how we power our lives, and use this story as a reminder that vision, patience, and courage can reshape not only one nation, but the way the world uses energy.
