The stacked bar chart illustrates the average electricity consumption (in watts) across five different categories in a typical household at two-hour intervals throughout a single day.
Overall, electricity usage fluctuates significantly within a 24-hour period, remaining relatively low during the early morning and peaking sharply in the evening. Additionally, while some categories like heating, lighting, and entertainment show substantial variation, the energy consumed by cold appliances remains remarkably constant.
Between 02:00 and 06:00, total power consumption hits its lowest point, hovering at approximately 250 watts. During these hours, heating & lighting along with cold appliances constitute the bulk of the energy used. From 08:00 onwards, usage climbs sharply to over 500 watts, driven by an increase in cooking, washing & drying, as well as entertainment, as the household begins its daily routines. This level remains relatively stable, fluctuating slightly between 500 and 600 watts until 16:00.
The peak period occurs in the evening, with consumption surging dramatically to hit the highest point of just over 800 watts at 18:00. This spike is predominantly caused by a massive increase in heating & lighting, which peaks at this time, alongside heightened entertainment and cooking activities. After 20:00, total wattage begins to decrease, dropping to around 650 watts by 22:00 as cooking and other activities wind down, though heating, lighting, and entertainment remain substantial contributors. Notably, cold appliances maintain a steady consumption of roughly 50 watts across the entire 24-hour duration.
