US data centers will account for approximately 20% of the nation's electricity consumption by 2035, more than tripling their current 5.9% share, according to analysis by BloombergNEF.
The projected surge in data center power consumption reflects the accelerating demand for cloud computing, artificial intelligence, and digital infrastructure across the economy.
Data centers currently consume roughly 5.9% of US electricity. By 2035, this figure will climb to around 20%, representing a dramatic shift in how the nation allocates its energy resources. This trajectory places data centers among the largest electricity consumers in the country, comparable to major industrial sectors.
The growth is driven by several factors. AI model training and inference require substantial computational power. Cloud services continue to expand as businesses migrate operations away from on-premises infrastructure. Cryptocurrency and blockchain applications add to demand, though at a smaller scale than cloud and AI workloads.
The power consumption surge presents challenges for grid operators and energy providers. Data centers require consistent, reliable power delivery, often necessitating new transmission infrastructure and generation capacity. The concentration of data center clusters in specific regions can strain local grids.
Data center operators are investing in efficiency improvements and renewable energy. Major technology companies have committed to powering facilities with wind and solar energy. Innovations in cooling systems, chip design, and power distribution aim to reduce energy waste. Liquid cooling and advanced chip architectures show promise in limiting consumption growth.
The timing matters critically. Grid capacity additions typically take years to plan and construct. Energy providers must begin infrastructure expansion now to accommodate 2035 demand projections. Regions with abundant renewable energy sources and available land increasingly attract data center investment.
The 20% projection assumes current technology and deployment trends continue. Significant breakthroughs in chip efficiency or AI model optimization could alter the trajectory. Conversely, faster AI adoption could push consumption higher.
Data center power demand will reshape US energy policy, infrastructure investment, and grid planning for years ahead.
Belgian prosecutors arrested a Belgian-Chinese man in May for allegedly stealing trade secrets from Belgan, a now-bankrupt gallium nitride semiconductor manufacturer. Prosecutors claim evidence suggests the suspect took a position at a tech company in China months after joining the defunct chipmaker.
Major smartphone manufacturers are failing to meet European Union repairability requirements that took effect this year, according to reports. The non-compliance suggests enforcement gaps in the EU's Right to Repair directive.
The US has raised censorship concerns over UK proposals requiring tech platforms to prominently feature vetted news providers in social and video feeds. The News Media Association warns the policy could harm the news sector.
TiVo is ending its free automatic commercial-skipping feature in November and replacing it with a paid premium service. Users who want to skip ads in their own recordings will need to pay extra.
