Global data-center electricity in 2024
About 1.5% of global electricity use. This covers all data centers—not AI alone. IEA 2025 report.

Understand the electricity, water, materials, infrastructure, and uncertainty behind AI—and ask better questions about local impact.
Mississippi communities do not have identical needs, infrastructure, histories, or access. Use the evidence and tools as a starting point, then let local people shape the purpose, examples, pace, safeguards, and measures of success.
Does a number describe AI alone or all data-center activity?
Is it a measurement, estimate, modeled projection, or company claim?
Does water use mean withdrawal or consumption—and is it direct or indirect?
What electricity sources, equipment, and local infrastructure are involved?
Are claimed environmental benefits actually measured against a realistic alternative?
These figures describe different years, geographies, and scopes. Projection is not observation, and data-center totals are not AI-only totals.
About 1.5% of global electricity use. This covers all data centers—not AI alone. IEA 2025 report.
The IEA’s 2026 update projects global data-center electricity use roughly doubling from 485 TWh in 2025. This is modeled, not measured.
Lawrence Berkeley National Laboratory’s 2026 update estimates a 9.5%–15.3% range for all U.S. data-center electricity use.
A 2025 LBNL-led study found enormous variation across scenarios, driven by servers, grids, cooling, climate, utilization, and refresh cycles.
The research shows fast growth and real resource use, but also wide uncertainty and enormous variation by equipment, grid, cooling, climate, and workload. This playbook teaches readers to preserve those distinctions.
International Energy Agency
IEA estimates data centers used about 415 TWh in 2024—around 1.5% of global electricity—and models multiple future scenarios because AI uptake, hardware efficiency, and energy constraints remain uncertain.
We use it for the 2024 baseline and to teach that projections are scenarios, not observations or promises.
International Energy Agency
IEA’s update projects global data-center electricity use rising from about 485 TWh in 2025 to about 950 TWh in 2030 while emphasizing bottlenecks, efficiency gains, and continuing uncertainty.
We use it to show why dates matter and why a newer projection may differ from an earlier report without making either one dishonest.
Lawrence Berkeley National Laboratory
LBNL’s reference case estimates data centers could use 11.8% of U.S. electricity in 2030, with a 9.5%–15.3% scenario range driven by equipment shipments, utilization, chip lifetimes, and cooling.
We use it to demonstrate how assumptions create a range and why total data-center demand must not be mislabeled as AI-only demand.
Lawrence Berkeley National Laboratory researchers
The study finds workload-level water use can vary by more than 10,000 times because server efficiency, grid water intensity, utilization, cooling, climate, and refresh cycles differ.
We use it to reject a universal per-prompt water number and to teach readers which local and technical details change the result.
Nature Sustainability
The study models energy, water, and carbon together and finds that location, grid change, efficiency, server utilization, and expansion scale create deep uncertainty and different tradeoffs.
We use it to connect operational and indirect impacts and to show why local infrastructure and assumptions belong beside any headline result.
U.S. Environmental Protection Agency
EPA places waste prevention, longer product life, reuse, repair, refurbishment, and then recycling within a whole-lifecycle approach to electronics.
We use it to expand sustainability beyond electricity and water to procurement, equipment life, reuse, and end-of-life decisions.
Mississippi Department of Environmental Quality
MDEQ provides environmental permit programs, applications, public notices, permit-board information, and guidance for groundwater and surface-water withdrawals.
We use it to give residents a direct place to investigate a Mississippi proposal and identify the permits, water questions, and public participation opportunities that may apply.
Mississippi Public Service Commission
The Public Service Commission publishes current and archived utility dockets that document matters before the commission.
We use it to help readers move from general energy claims to the actual utility record for a Mississippi project or proceeding.
Sources and requirements can change. Check the publication date, read the original material, and confirm the rules that apply locally before making a consequential decision.
Use these six ideas to compare environmental claims, understand what is known, and spot what is still uncertain.
AI runs on physical infrastructure. Electricity powers computing, storage, networking, and cooling. Water may be used directly for cooling and indirectly for electricity and chip manufacturing. Hardware depends on semiconductors, metals, minerals, global supply chains, and eventual reuse or disposal.
Model size, type of task, server efficiency, utilization, cooling, local climate, electricity mix, and facility design all change the result. A fixed energy or water claim for every prompt conceals this variation.
Efficiency measures how much computing is achieved with a unit of electricity. Carbon intensity describes emissions associated with that electricity. A facility may become more efficient while total demand rises because the facility or workload grows.
AI is used for electricity forecasting, building management, maintenance, research, and process efficiency. These are potential wider benefits, not automatic net reductions. Compare measured results with a credible alternative.
A new data center can affect utility planning, infrastructure, water, land use, public costs, and employment. The Commons does not take a predetermined position; it helps residents investigate evidence.
Students can compare AI with other approaches; educators can teach facts versus projections; universities can evaluate vendors and hardware lifecycles; small businesses can demand measurable value; startups can design for model efficiency; nonprofits can balance mission benefit with resources; and residents can use public records to participate in local decisions.
✓ Teaching data literacy with real energy and water evidence
✓ Comparing model or hosting efficiency during product design
✓ Using public records to ask informed local planning questions
× Repeating one fixed water or energy number for every AI prompt
× Treating all data-center demand as AI-specific
× Assuming a projected benefit has already produced a measured reduction
Use these tools to compare evidence, ask better questions, and discuss tradeoffs without overstating what the numbers prove.
A printable guide to the system behind the headline.
Test the quality and boundaries of an environmental claim.
Find records that can answer questions about a specific proposal.
Sort environmental claims by the evidence they actually provide.
Read each claim and underline the number, place, date, system, and source.
Label it measured fact, estimate, modeled projection, company-reported figure, misleading statement, or unknown.
Check whether it covers AI alone or all data-center activity.
Name the assumptions or missing information that could change the conclusion.
Rewrite the claim so a community member can understand both the finding and its limits.
Which missing detail most changed how you interpreted the claim?
Share the plan with the people responsible for the work and the people who may be affected. Confirm local rules, protect private information, and name the person who can answer questions or correct a problem.
