Mayo Nissen’s poster visualizes a home’s power usage over 24 hours and compares it to an average of data collected over four days. The point is not simply to understand energy-usage patterns but also to give narrative shape to our everyday activities. The power data on the graph, which was recorded at one-minute intervals, reconstructs the activities of a given day in its spikes and lulls; the designer muses, “Was that spike at 3am a one-off nighttime cup of tea…and can boiling the kettle just once really use so much power? That consistent peak must be dinnertime. Is that wave in the graph, visible at night, the fridge on its cycle, running all day every day?” The chart’s light gray lines show each minute of each day; the thick black line represents the average energy used over four days; and the red line is what is known in statistics as a “smoothed average,” revealing broader usage patterns.
