What is the term for the act of using energy or power?

• A. Power usage
• B. Energy consumption
• C. Energy efficiency
• D. Fuel consumption

Answer: (B)

When we talk about using energy, the idea captured is energy consumption—the total amount of energy used over a period. It describes the act of consuming energy, not how fast you use it. Power, on the other hand, is the rate at which energy is used at a moment, so it’s about speed rather than total amount. Energy efficiency refers to doing the same work with less energy, not the act of using energy itself. Fuel consumption is specific to fuels like gasoline, rather than energy use in general. So, the term that best fits “the act of using energy or power” is energy consumption.
