data center efficiency 3

We measure data center efficiency by how much computing power we get per watt of electricity, and it's been a huge focus lately because cooling and powering all those servers eats up a lot of energy. Modern designs use hot and cold aisle containment, variable-speed fans, and even liquid cooling to reduce waste, while software can shift workloads to times and places with cheaper or greener energy. Every improvement cuts costs and carbon emissions, making the whole operation leaner.
