Diving into the heart of one of the 5 oil supermajors, TOTAL. The company with 1,000 subsidiaries, which has built its empire in 130 countries by producing oil and gas, has become TotalEnergies in this year 2021 with a change of name and logo. But how does an oil company become an energy company ?  Can TotalEnergies really be a credible player in the energy transition? From the company's French headquarters to the wind farm in New Mexico, people believe in it, convinced that this transformation is real. The company's engineers and CEO Patrick Pouyanné assure us that this is not greenwashing, that our future and that of the planet are now inseparable from the company's development. But from Texas to Uganda, including the Gulf of Mexico, oil and gas are still at the heart of this multinational company’s activities, which raises doubts about the effectiveness of the ecological transition announced and carried out with great fanfare.
