How will cities cope with the surging power demand due to data centers?
Susanna Kass: The keys are to shift data centers from fossil-based power to clean energy, and to recover and re-use heat waste so that it becomes a resource, rather than a byproduct.
Data centers run 24 hours a day, and their cooling systems continuously generate warm water that can be captured and pumped through underground pipes to serve nearby buildings such as offices, residences, or factories. This "district heating" approach is already well established in the Nordic countries. It serves about 40% of the roughly 100,000 homes in Espoo, Finland, a city near Helsinki. In Sweden, facilities south of Stockholm feed recovered heat waste into systems serving about 100,000 homes. These cities are turning heat waste from data servers into a primary energy source.
