Data Centers
Facilities housing computing infrastructure, including the servers and GPUs used for AI training and inference, which are significant and growing consumers of copper, gallium and other metals for power and cooling systems.

Overview
Data centers are the buildings that house the physical servers, storage and networking equipment behind cloud computing, corporate IT and, increasingly, AI. As a category distinct from data center infrastructure firms or cloud software providers, "data centers" generally refers to the industry of owning and running these facilities as a service — leasing space, power and connectivity to tenants who bring their own equipment, or in the case of hyperscalers, running facilities purely for internal use. The industry has shifted rapidly from a fairly steady, predictable business tied to enterprise IT growth into one of the fastest-expanding parts of the global economy, as demand for AI computing has pushed electricity and space requirements up faster than new capacity can be built.
Key Metals & Materials Used
Copper dominates a data center's material list, running through power distribution, grounding systems and the miles of network cabling that connect racks to switches. Lead remains the standard chemistry for the batteries in uninterruptible power supply systems that bridge the gap between a utility outage and generator startup, though lithium-ion battery racks are gaining ground for their smaller size and longer cycle life. Aluminum appears in server chassis, cable management and cooling components, while steel forms server racks and the building structure itself. Server hardware layers on additional demand for gold-plated connectors, silver in some electrical contacts, and rare earth elements in the magnets used inside hard drives and cooling fans.
How the Industry Operates
Facilities are engineered around redundancy, typically rated on a tier system from Tier I (basic) to Tier IV (fully fault-tolerant, no single point of failure). Utility power feeds the building through substations, with backup power supplied first by battery banks that hold the load for seconds to minutes, then by diesel or gas generators that can run indefinitely with enough fuel. Cooling systems keep server rooms within a narrow temperature and humidity band, since even brief overheating can force automatic shutdowns to protect hardware. Operators monitor power usage effectiveness, a ratio of total facility energy to energy actually used by computing equipment, as their core efficiency benchmark, and the best modern facilities push that ratio close to 1.1, meaning very little energy is lost to overhead like cooling and power conversion.
Byproducts & Waste Streams
Waste heat is the largest and least-used byproduct in most facilities, simply exhausted outdoors even though it could theoretically warm nearby buildings. Water consumption from evaporative cooling towers is a growing concern in water-stressed regions, prompting some operators to shift toward air-cooled or closed-loop systems that use far less. Retired servers and networking gear, typically replaced every three to five years, generate a steady flow of electronic waste rich in recoverable copper, aluminum and precious metals, handled through certified IT asset disposition vendors. Backup batteries reaching end of life — whether lead-acid or lithium-ion — require separate hazardous-material recycling streams, and diesel generator testing produces periodic exhaust emissions subject to local air permits.
Who It Serves
Enterprises of every size rent colocation space rather than build their own facilities, paying for power, cooling, physical security and network connectivity. Cloud providers use both owned and leased data centers to deliver their platforms to millions of end customers. Financial services firms depend on data centers for latency-sensitive trading systems as well as standard back-office computing, while healthcare, government and telecom organizations use them to meet strict uptime and compliance requirements. Content and streaming companies lease space specifically to position servers close to end users, cutting the delay in delivering video and other high-bandwidth content.
Role in Everyday Life
Every text message, video call, cloud photo backup and mobile app login depends on a data center somewhere finishing the request and sending a response back, usually within a fraction of a second. Online shopping checkouts, ATM withdrawals and hospital medical records all run through facilities like these, which is why their reliability is treated as critical infrastructure rather than ordinary business real estate. Most people never see a data center or know which one handles their data, but a facility going offline can knock out banking apps, streaming services or work email for millions of people at once, which is exactly why the industry invests so heavily in backup systems most people never notice are there.

Michael Burry Bets on Copper Over AI, Citing a Widening Supply-Demand Gap
Data centers are the demand-side subject of Burry's thesis, consuming large volumes of copper for power and cooling infrastructure, though the article doesn't suggest a direct cost or supply risk to data-center construction itself.

Data centers' own electricity costs and supply security are the subject of the House vote driving this trade, tying data-center economics directly to nuclear-sector sentiment.
AI Data Centers Help Push Uranium's Long-Term Price to an 18-Year High
Data center operators securing nuclear power to meet AI-driven electricity demand are now facing the same tightening uranium market as traditional utilities, at prices not seen in nearly two decades.
AI Data Centers' Shift to 800-Volt Power Could Cut Copper Use 45% While Boosting Gallium Chip Demand
800VDC architecture reduces copper costs and conversion losses for data center operators building AI infrastructure, but requires new capital investment in different power hardware -- a genuine tradeoff rather than a clear net positive or negative for the industry.
China's Grip on Indium Phosphide Squeezes AI Chipmakers as Wafer Prices Surge 250%
AI data-center operators depend on indium-phosphide-based optical transceivers to scale their networks, and a global capacity shortfall of up to 70% threatens to slow buildouts or raise their cost.
Data Centers Are on Track to Use as Much Silver as an Entire Country Mines in a Year
Data center operators face growing exposure to silver supply and pricing as their silver consumption for chip packaging, connectors and thermal management scales with AI infrastructure buildout.
Copper's Record Run Reflects a Supply Squeeze That Could Take 17 Years to Fix, Sprott Says
AI data center buildout is itself a major source of copper demand, so a persistent supply deficit raises the metal cost of new capacity.
Battery Storage Overtakes EVs as Lithium's Fastest-Growing Demand Source
Data centers have emerged as a new, fast-growing battery storage buyer (45 GW of backup capacity in 2025, up 30%), but the story so far is about their role as an emerging demand source, not their own cost exposure.
