Deep dives

The Growth of Data Centers and Energy Demand

The expansion of data centers is poised to significantly impact global energy consumption, with estimates suggesting that they could account for a substantial portion of power usage in the near future. This trend parallels historical infrastructure build-outs, such as railways and electrification, where massive investments were required to support emerging technologies. As AI technology develops, the financial stakes in building data centers escalate rapidly, with projections indicating a need for trillions of dollars in investment to address both current and future electricity demands. This ongoing build-out highlights the complexities of forecasting demand and managing the associated overinvestment risks often seen in high-growth sectors.
