In general, data centers are buildings which house computer systems, such as servers. All internet activity requires the use of servers, to some extent–some more than others. Website hosting and social media usage require relatively little computing power, while activities like bitcoin mining and using AI prompts uses considerably more. Computer systems require electricity for power and water for cooling, so the more computing power required, the more water and electricity the data center consumes.
AI data centers are a new type of data center, specifically designed to process vast quantities of data in order to run artificial intelligence systems. Instead of the Central Processing Units (CPUs) which power standard data centers, AI data centers use Graphics Processing Units (GPUs); these generate significantly more heat. As a result, AI data centers require significantly more water for cooling and significantly more energy than their non-AI counterparts.
