Question: 1 / 400

Which technology is commonly used to monitor energy usage in buildings?

Smart meters

Smart meters are commonly used for monitoring energy usage in buildings due to their advanced capabilities in providing real-time data on energy consumption. Unlike standard light bulbs, which only serve the purpose of lighting and do not provide any data, smart meters actively track and report energy usage patterns. They can communicate with utility providers for billing purposes and can also help building managers and occupants make informed decisions about energy consumption.

Furthermore, analog clocks and manual energy logs lack the efficiency and accuracy of smart meters. Analog clocks simply tell time and do not relate to energy monitoring, while manual energy logs require human input, are prone to errors, and do not provide instantaneous feedback on energy usage. Therefore, smart meters stand out as the most effective and practical technology for monitoring energy usage in buildings.
