Data centers have become an important part of the modern economy. Every time you ask a chatbot a question, stream a video, or save a photo to the cloud, a data center somewhere is burning electricity to make it happen. In 2025, the United States’ data centers accounted for roughly 5% of total electricity consumption in the country. That was much higher than the global average of 1.5%. China and Europe also have large data-center industries, but their share of electricity consumption was lower.
Key Takeaways
- The United States data centers eat up 5% of all the electricity the country uses, more than three times the global average.
- Europe is sitting at 2%, while China, despite building enormous numbers of data centers, is still only at 1%.
- Most of the developing world barely registers yet — the Middle East, Africa, and Central & South America are all under half a percent.
Data Center Electricity Use as a Share of Total Consumption (2025)
The table below shows how much of total electricity consumption is used by data centers across major regions in 2025. The data is based on estimates and analysis from the International Energy Agency (IEA) and Ember.
| Country / Region | Share of Electricity Consumed by Data Centers (2025) |
|---|---|
| United States | 5.0% |
| Europe | 2.0% |
| Global | 1.5% |
| China | 1.0% |
| Middle East | 0.3% |
| Africa | 0.2% |
| Central & South America | 0.1% |
United States
In America data centers now use 5% of all the electricity the country consumes, and that number is climbing quickly. Big tech companies have been building huge AI computing campuses across the country. A handful of regions — mostly in Virginia, Texas, and a few other hotspots — now host nearly half of all US data center capacity. That concentration is part of why local power grids in those areas are under real pressure.
Europe
Europe sits at 2%, well above the global average but still far behind the US. Growth in electricity consumption by data centers has been slower and more gradual in Europe. The one reason is that Europe has less of the AI computing boom happening on its own soil compared to America.
Additionally energy costs have also been higher in Europe for years, making large, power-hungry data centers more expensive to operate. Even so, the share is expected to keep climbing as more cloud and AI infrastructure gets built in countries like Ireland, Germany, and the Netherlands.
China
China is the second-largest data center market in the world by total electricity used. However, China’s overall economy and electricity grid are so massive, data centers still only make up about 1% of its total consumption. China has also been getting more efficient with its cooling and computing setups, which has helped keep this share from growing as fast as America’s, even as the country keeps building new facilities.
Middle East
The Middle East sits at just 0.3% for now, but countries like the UAE and Saudi Arabia have been investing heavily in becoming AI and cloud computing hubs.
Africa
In Africa, data centers account for just 0.2% of total electricity consumption. This shows both a smaller digital infrastructure footprint overall and the fact that most African countries still don’t have the reliable, large-scale power grids that big data centers need. As internet access and cloud services expand across the continent, this number will likely creep upward.
United States vs. China:
The US uses five times more of its own electricity on data centers than China does, even though China is home to more people and a huge amount of global manufacturing. The difference comes down to where the AI computing boom is actually happening. Most of the world’s largest AI companies, cloud providers, and AI training facilities are based in the US, and they’ve been racing to build capacity as fast as possible.
U.S. vs China: Energy Consumption Per Person (2000–2024)
China is building data centers too, and is projected to add more new data center electricity demand than almost any other country over the next few years. China is starting from a much lower base, and its enormous overall electricity consumption keeps the percentage share small for now.
The Bottom Line
The United States is already feeling the pressure of powering the AI boom, Europe isn’t far behind, and China is quietly building up the capacity. Regions like Africa, the Middle East, and Latin America are still on the sidelines, but that will likely change as more of the world plugs into cloud computing and AI.
