An instrument designed to estimate the total electrical energy used by a residence over a specific period. These tools often require input data such as the quantity and wattage of appliances, usage frequency, and duration. For example, entering data for a refrigerator, including its wattage and daily operating hours, allows the instrument to approximate the electrical energy the appliance will consume.
Accurately assessing power use is valuable for budgeting, identifying energy inefficiencies, and promoting conservation. Understanding energy expenditures allows occupants to make informed decisions about appliance usage, potentially reducing expenses and environmental impact. Historically, these assessments were manual and time-intensive, but technological advancements have led to user-friendly online and software-based options, enhancing accessibility and accuracy.
