Data centers consume just two to three percent of the planet’s total electricity usage. So reducing data centers’ climate footprint may not seem, at first blush, to be a high priority as world leaders gather in New York next week to consider practical climate change solutions at the UN Climate Action Summit.
However there are at least two reasons why data centers will likely play a key role in any attempt to curb global emissions. First, as cloud computing becomes more energy-efficient and increasingly relies on renewable sources, other sectors such as manufacturing, transportation, and buildings could turn to green data centers to reduce their own emissions. For example—a car manufacturer might outsource all of its in-house computing to zero-emission data centers.
Even without such partnerships, though, data centers will likely play an important part in the climate’s future. The rise of AI, machine learning, big data, and the Internet of Things mean that data centers’ global electricity consumption will continue to increase. By one estimate, consumption could jump to as much as 13 percent of the world’s total electricity demand by 2030.
For these reasons, says Johan Falk, senior innovation fellow at the Stockholm Resilience Center in Sweden, data centers will have outsized importance in climate change mitigation efforts. And the more progress society makes in the near term, the sooner the benefits will begin to multiply.
