Your energy usage depends on factors like the size of your home, number of occupants, appliances, and climate. Monitoring your electricity usage through smart meters or energy monitoring devices can help you track and manage your energy consumption. Making small changes like using energy-efficient appliances, turning off lights when not in use, and insulating your home can help reduce your energy usage.

Factors that affect how much energy you use include the type of appliances and electronics you use in your home, as well as your energy consumption habits such as how often you use these devices and for how long. Additionally, weather conditions like extremes of temperature can impact how much energy you use for heating or cooling.
Incandescent light bulbs are not energy efficient, as much of the energy they use is converted into heat rather than light. Only about 10% of the energy they consume is actually turned into light.
The number that tells you how much electrical energy a machine will use in one year of average use is called the annual energy consumption in kilowatt-hours (kWh). It is a measure of the total energy the machine consumes over the course of a year if used normally.
Most dishwashers use around 1-2 kWh of energy per cycle and around 4-6 gallons of water per cycle. Newer energy-efficient models may use less energy and water.
