Which of the following is a common unit of measurement for energy consumption?

Kilowatt-hours are a standard unit of measurement for energy consumption, particularly in the context of electricity usage. This unit expresses the amount of energy used over time, specifically the energy used when powering a device that consumes 1,000 watts for one hour. It is a practical measurement for both consumers and utility companies, allowing for easy billing and understanding of energy usage over time.

In residential settings, kilowatt-hours are commonly used in electric meters, making it easier for individuals to track and manage their energy consumption for heating, cooling, and other electrical devices. Other units like Joules, foot-pounds, and BTUs are certainly associated with energy but are less common in the everyday context of measuring electricity usage. Joules are a smaller unit used in scientific contexts, foot-pounds relate to work done, and BTUs (British Thermal Units) are primarily used for heating and cooling calculations, but kilowatt-hours remain the most straightforward and widely recognized unit for measuring and billing energy consumption in homes and businesses.
