Modular data centers can be transported on a truck for rapid deployment

Most data centers rely on the local power grid to feed power-hungry computer equipment

These facilities house rows of vertical racks containing multiple types of hardware, including servers that provide 24/7 access to online applications, services, and data. In a hyperscale center with thousands of these racks, the annual electricity used is estimated to equal that of 400,000 electric vehicles.

Today's massive data centers evolved from single-room mainframes

Punch card computers from the late 1940s were used to store and process a company's data locally before the advent of desktop computers. As the amount of data and company sizes increased alongside the miniaturization of technology, mainframes were replaced by local server rooms and external facilities with interconnected servers running cloud-based and AI software.

AI data center growth has created shortages and price hikes in computer parts

The parallel processing needed to power large language models for AI chatbots and other tools drove demand for high-speed graphics processing units to spike in 2025, enabling capital-rich technology companies to price out consumers.

Before installing racks of servers and other equipment, floors are raised beneath where they will be installed to create space for cold fluid to be pumped into the hardware and to facilitate cable management.

Data center power demands have delayed the retirement of coal plants

US data center power consumption is expected to triple by 2035 to meet the growing infrastructure needs of AI platforms. Longer construction times and higher startup costs for renewable energy systems such as wind and solar have led to at least 15 coal power plant closures being postponed.

Underwater data centers may provide an alternative to energy-intensive air cooling

By submerging electronic hardware into a non-conductive fluid, such as an oil with strong thermal transfer properties, significant thermal energy can be quickly drawn away from a chip and brought to the surface as warm materials rise. Thermal energy can then be removed from the fluid with a heat exchanger before it is recirculated.

Electrical grids worldwide must double their power delivery capacity by 2050 to meet surging demand from AI and electric vehicles.
