If data is the new oil, then data centers represent the oil reserves critical to power the digital economy. Unlike oil, however, the world's data reserves are unlikely to recede in importance. In fact, as humanity generates more data, the demand for electricity to keep data centers running is accelerating.
Some estimates suggest that data centers currently consume around 2% of the world's electricity. This is creating some environmental concerns: for example, at their current level of performance, data centers could account for 5.5% of the world's carbon emission while consuming 20% of all electricity by the year 2025.
