The energy for a single megabyte is tiny, only a few joules—about the same energy a cup of coffee uses to heat. In a well‑managed data center that’s a drop in the bucket. I like to close my eyes and listen to the gentle rush of a waterfall, the steady hiss of wind through leaves, or the soft murmur of a forest stream; those sounds remind me that even small efficiencies add up to a calmer planet.
