The Energy Exchange - How Do We Power Our Energy Hungry World?

As global electricity demand enters an unprecedented phase of acceleration, driven by the electrification of uses and the rise of artificial intelligence, energy systems face a dual challenge: meeting rapidly growing demand while significantly reducing CO₂ emissions.

In this context, electricity is emerging as an essential pillar of tomorrow's energy system, both as a driver of decarbonization and a lever for energy security. However, this transformation is putting increasing pressure on existing infrastructures, particularly power grids, and calls for a fundamental rethink of the balance between generation, flexibility and consumption.

In this second episode of Energy Exchange, three experts share their perspectives on the new challenges facing electricity:

• Sophie Chevalier (Senior Vice President Flexible Power & Integration at TotalEnergies)
• Elisabeth Cremona (Senior Energy Analyst at Ember)
• Simon Flowers (Chairman and Chief Analyst at Wood Mackenzie)

A surge in global electricity demand

Global electricity demand is entering a phase of strong acceleration, with expected growth of 35-40% over the next decade. In 2025 alone, demand increased by 850 TWh, equivalent to Brazil's annual electricity consumption.

This trend is driven by structural factors: rising incomes are boosting demand for electrical equipment and cooling, while developing countries require increasing amounts of energy to support economic growth and improve living standards.

Finally, this growth is largely driven by the electrification of uses - transport, industry and buildings - which are the main CO₂-emitting sectors. As a result, electrification is emerging as a central lever for decarbonizing the energy mix.

The expansion of data centers: a new challenge for power systems

The growth of data centers, driven by the rise of artificial intelligence, is a rapid and large-scale phenomenon. Demand is increasing faster than supply capacity, and the entire electricity value chain must adapt to keep pace.

Data centers are highly energy-intensive and require a reliable, continuous and secure power supply, often ensured through long-term electricity purchase agreements (PPAs).

The scale of this expansion is particularly visible in the United States, where demand could increase fourfold in the coming years. In this context, in 2026 TotalEnergies signed long-term power purchase agreements (PPAs) with Google to supply more than 30 TWh of renewable electricity to its data centers located in Texas.

Strained grids: the challenge of adaptation

Originally designed for a centralized and relatively stable system, power grids must now evolve to adapt to a deeply transformed environment. The rise of renewables is leading to a more decentralized and variable production, significantly increasing system complexity: maintaining the balance between supply and demand at all times is becoming more challenging.

At the same time, infrastructure development struggles to keep pace. High-voltage power lines can take 10 to 12 years to build in Europe, while new uses such as data centers can come online in just a few years.

As the energy mix evolves, it is essential to adapt both the grid and its operations, in order to maintain system stability and avoid major disruptions.

The complementarity of renewables and flexible assets

Electricity is now emerging as a key pillar of energy security, enabling countries to diversify their energy mix and reduce their dependence on energy imports. In this context, the development of energy systems relies on scaling up renewables and strengthening power grids.

At the same time, the growth of low-carbon electricity is accelerating rapidly. Its production has not only kept pace with rising demand but has at times exceeded it. Solar power alone covered nearly 75% of the new demand recorded.

This increase in capacity comes with a key challenge: the variability of production. Flexible assets, such as gas power plants and battery storage systems, are essential to ensure the balance between supply and demand at all times. Batteries also play a crucial role, helping both to better integrate renewable energy and to optimize the use of power grids.

It is this complementarity between renewables and flexible capacity that makes it possible to reconcile the three key objectives of the power system: reliability, affordability and decarbonization.

TotalEnergies' Integrated Power strategy: addressing the new challenges of electricity

TotalEnergies is deploying an integrated approach to electricity, with the objective of meeting this fast-growing demand with more reliable, more sustainable and more affordable power.

This Integrated Power model combines renewable generation, flexibility, storage and digital optimization to deliver solutions tailored to customer needs.

By 2030, the Company aims to reach a net electricity production of 100 to 120 TWh per year, with around 70% from renewable sources and 30% from flexible generation.
