A crucial insight into your household energy habits can come from comparing your peak and minimum energy usage over the course of the day. Most households consume the most power during the evening, from around 5 to 8 p.m., when people are making dinner, turning up the heat, turning on all the lights and using their home entertainment. Find out how your household’s consumption fluctuates hour by hour. Choose ‘Custom’ under the period bar to set the parameters, or just click on the vertical bar representing any one day in the bar graph. Note the difference between your peak hours and the times of lowest usage, when everyone is asleep. You may want to consider ways to cut this always-on consumption – for example, by lowering the nighttime temperature and unplugging unused electronics and appliances that draw standby power.
