3.6% annual growth in electricity demand between 2026 and 2030 in the United States and Europe. This figure from the International Energy Agency marks the end of a cycle. Since 2010, developed countries had stabilized their electricity consumption through energy efficiency gains and deindustrialization. Artificial intelligence, data centers, and the return of factories to Western soil are breaking this trajectory.
This acceleration — 50% faster than the past decade — confronts the energy transition with an unforeseen challenge: massively electrifying societies while meeting demand that is rising again. Electrical infrastructures, designed for stable consumption, must absorb the equivalent of several medium-sized economies in five years.
The essentials
- American and European electricity demand will grow 3.6% annually between 2026-2030, versus 2.4% for the 2010-2020 decade
- AI and data centers will represent 40% of this new growth according to the IEA
- Reindustrialization of semiconductors and batteries adds 25% to this increase
- Western electrical grids must integrate 800 TWh additional by 2030
Data centers explode base consumption
Microsoft, Google, Meta and Amazon are building the equivalent of ten nuclear power plants in data centers over five years. Training a model like GPT-4 consumes 50 GWh, equivalent to the annual electricity of 15,000 American households. ChatGPT processes 1.7 billion requests per day, each requiring ten times more energy than a standard Google search.
Nvidia delivers 3 million H100 chips per year, each consuming 700 watts continuously. Connected 24/7, these chips consume as much as a city of 2 million inhabitants. The California company plans to triple this production by 2027 with its B200 chips, which are even more power-hungry.
American electrical geography is being reconfigured. Northern Virginia, the global hub of data centers, sees demand surge 6% annually. The state now consumes more electricity than Greece. Phoenix, Las Vegas, and Austin are following the same curve, attracting technology giants with their low energy costs and robust networks.
Industry returns to Western soil
The revenge of Davids in the arena of artificial intelligence is also transforming traditional industry. Intel is investing 100 billion dollars in semiconductor factories on American soil. TSMC is establishing three mega-fabs in Arizona, each consuming as much as a city of 300,000 inhabitants.
Europe is accelerating its energy-intensive reindustrialization. The European battery plan mobilizes 200 billion euros to create 30 gigafactories by 2030. Each battery factory consumes 500 MW continuously, equivalent to the electricity of Toulouse. Northvolt in Sweden, BYD in Hungary, Tesla in Germany: the battery industry is redesigning the continental electrical map.
Steel manufacturing is adopting green hydrogen, quadrupling its electricity consumption. ArcelorMittal is converting its European blast furnaces to electrolysis by 2030. ThyssenKrupp in Germany, Salzgitter in the Netherlands: 40 Mt of steel will switch to electrolytic hydrogen, requiring an additional 300 TWh.
Electrical grids under structural strain
This new demand tests the physical limits of networks. PJM, the electrical operator of the American Northeast, is now refusing 30% of connection requests due to lack of capacity. Waiting lists are growing: four years to connect a medium-sized data center, versus eight months in 2020.
Europe faces the same bottleneck. RTE, the French operator, has identified 60 GW of industrial projects awaiting connection, equivalent to 40% of the country’s installed capacity. Germany is blocking new energy-intensive installations in the south, saturated by Bavarian renewables. TenneT, the Dutch operator, is imposing a moratorium on data centers in the Amsterdam region.
Electrical transformers are in short supply. ABB and Siemens are experiencing 18-month delivery delays compared to six months before 2022. The electrical substations required cost 50 million euros each and take three years to build. General Electric estimates the European deficit at 400 high-voltage transformers by 2028.
Renewable production accelerates but falls short
Offshore wind and solar are setting installation records. The United States is adding 30 GW of renewable capacity annually, Europe 40 GW. But this intermittent production complicates the equation. Data centers require constant power supply. The battery industry tolerates no outages.
Storage is progressing too slowly. Tesla is installing 15 GWh of grid-scale batteries annually in the United States, but backup demand reaches 200 GWh. Europe is deploying 8 GWh annually when 150 GWh would be needed. Long-duration storage technologies — hydrogen, compressed air — remain marginal and costly.
Coal is dead, long live coal reveals a cruel paradox: some American states are restarting their gas plants to meet AI demand peaks. Georgia, North Carolina, and Virginia are authorizing new fossil turbines, officially “transitional” but destined to operate for fifteen years.
European energy models face the American wall
Europe discovers its structural disadvantage. Industrial electricity costs 150 €/MWh compared to $80 in the United States. European technology giants — SAP, ASML, Spotify — lease their computing power across the Atlantic rather than developing it locally.
Microsoft is closing its AI training centers in Ireland and Denmark to relocate them in Virginia and Texas. Meta is concentrating its servers in North Carolina where Duke Energy guarantees 2 GW of dedicated capacity. Google is developing its Gemini AI from Oklahoma, powered by local wind energy at $30/MWh.
France is banking on nuclear to reclaim its electrical competitiveness. EDF is relaunching six EPRs by 2040, promising decarbonized electricity at €60/MWh. But these reactors will produce at the earliest in 2035. The United Kingdom, Poland, and the Netherlands are following with their nuclear programs, a race against the clock against digital exodus.
Germany is testing another path: hydrogen imported from North Africa and the Middle East. The SoutH2 corridor will transport 10 Mt of hydrogen per year via Italy starting in 2030. Riskier than French nuclear but potentially faster to deploy.
This electrical rupture is redefining Western industrial geopolitics. Countries that secure their electricity supply at competitive prices will keep their digital champions. The others will become technological peripheries, importing their artificial intelligence as they import their smartphones.
