A device that consumes a lower amount of energy is typically referred to as an energy-efficient device. It can be either an electrical or electronic device, or even both. The terms "electrical" and "electronic" are often used interchangeably, but they have slightly different meanings.

"Electrical" generally refers to devices that operate using electricity, such as appliances, lighting fixtures, or power tools. "Electronic" typically refers to devices that utilize electronic circuits and components to perform specific functions, such as computers, smartphones, or televisions.

Therefore, an energy-efficient device can fall into either the electrical or electronic category, or it can be a device that combines both electrical and electronic components. The term "energy-efficient" focuses on the device's ability to minimize energy consumption while maintaining its functionality.
