Behind a miles-long gray wall in the central Mexico town of Colón, a Microsoft data center portends the future for other data centers in the country. Like Mexico, countries around the world are scrambling to meet the rising energy demands of data centers, spurred by a boom in artificial intelligence and cloud computing. Worldwide, nearly 60% of the electricity used by data centers comes from fossil fuels including natural gas. There are 15 data centers of varying capacities operating in Querétaro today, with an energy requirement of 200MW — about 80% of the total requirement of data centers in the country. The Mexican Association of Data Centers estimates that over 70 additional data centers will be built in the country over the next five years.
