Because the sun is up, we will turn on fewer lights in our homes. Thus, we actually use less energy in the morning. In the winter, the afternoon Daylight Saving Time advantage is offset by the morning's need for more lighting. In spring and fall, the advantage is less than one hour. This means that less electricity would be used for lighting and appliances late in the day.
Most people plan outdoor activities in the extra daylight hours.
When we are not at home, we don't turn on the appliances and lights. There is a small public health benefit to Daylight Saving time. Occasionally people complain about daylight saving time. A frequent complaint is the inconvenience of changing many clocks, and adjusting to a new sleep schedule. For most people, this is a mere nuisance, but some people with sleep disorders find this transition very difficult.
