No two families will use the exact amount of electricity in a given time period. Many factors cause variances in the amount of electricity used by different customers. Some of these factors include the age of the home, the size of the home, the type of heating/cooling unit, the type of water heater, the efficiency of appliances, the type and amount of insulation and the type and number of windows in a home. Personal comfort levels can vary greatly, and since most energy is consumed from heating and cooling the home, thermostat settings can be a major factor in the amount of electricity consumed. For example, some people set their thermostat and don’t change it for the entire season while others move the thermostat up and down. The number of people in a home can also affect the amount of electricity consumed by more electronics and appliances being used, more baths or showers being taken, and more clothes being washed and dried, etc.
