The global electricity demand is predicted to rise significantly in the coming years, primarily due to the growing need from tech companies for data centers to support high-energy technologies like artificial intelligence (AI). Current climate policies and investments in renewable energy may face challenges as this demand increases unless stricter international regulations are established to ensure tech firms utilize clean energy rather than fossil fuels. The International Energy Agency (IEA) published a report indicating that investment in data centers has surged, especially in the U. S. , indicating a trend that is expected to continue. Specifically, annual investments in U. S. data center construction have doubled recently, with similar increases observed in China and the European Union.
In 2023, the total capital investment in data centers by major tech companies, such as Google, Microsoft, and Amazon, exceeded that of the U. S. oil and gas sector, accounting for about 0. 5 percent of the U. S. GDP. The tech industry anticipates broader deployment of AI technologies in the future. The IEA forecasts that global electricity demand may increase by 6,750 terawatt-hours (TWh) by 2030 due to factors like digital advancements, economic growth, electric vehicles, and electricity-intensive manufacturing. Currently, data centers in the U. S. , China, and the EU account for about 2 to 4 percent of total electricity usage, but some states in the U. S. report levels exceeding 10 percent. In Ireland, this figure is over 20 percent of total electricity consumption.
Although the speed and growth of AI remains uncertain, the demand for electricity from data centers and technologies like cryptocurrencies could reach 1,000 TWh by 2026, akin to current total electricity usage in Japan. The IEA advocates for increased dialogue between policymakers, tech developers, and the energy sector to manage energy expectations and consumption. There are pressing concerns that, without regulation, electricity needs from data centers might surpass those of some U. S. cities or states, raising challenges for land availability and clean energy supply.
Tech companies are reportedly engaged in intense competition for global dominance, necessitating continued investment in data centers, leading to increasing pressure on energy resources. While many current data centers function with around 40 MW capacity, “campuses” with capacities of 250 MW or more are anticipated to become more common soon, potentially consuming electricity equivalent to double the residential usage of Pittsburgh. The U. S. is likely to experience the most growth in data centers, with European power consumption expected to nearly triple by 2030, while China has made significant investments in developing its data centers.
To address the anticipated rise in electricity demand, a coordinated regulatory strategy is essential. Governments must set clear energy use limitations for tech firms to align with global climate commitments, like those in the Paris Agreement. One potential method involves mandating that tech companies meet their energy needs with renewable or nuclear power and possibly decelerating the deployment of energy-intensive technologies.
