It's a device that can convert energy of one form into another efficiently. Like a lightbulb for example, an energy efficient one would use less electricity but still produce as much light as one that is less efficient. It's a measure of what you get out versus what you put in.
An example of an energy efficient device includes an energy efficient light bulb.

An electric heater ( the only known 100% efficient device ).
Energy efficient devices need not look much different to those that aren't. It really depends what device you are talking about, though.
A device that makes energy easier to use could be a power converter or energy transformer that changes the form of energy (such as from mechanical to electrical) for more efficient use.
if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes
Leave the jar inside the refrigerator or freezer at least one hour for An obvious example of an automatic timer as a home energy saving device is a pool.
The most energy-efficient device often varies based on context, but generally, LED light bulbs are considered among the top choices for energy efficiency in lighting. They use up to 80% less energy than traditional incandescent bulbs while providing the same amount of light. In broader terms, Energy Star-rated appliances, like refrigerators and washing machines, are also highly energy-efficient, significantly reducing energy consumption compared to non-rated models.
An energy efficient motor.
Any dishwasher that is Energy Star Rated is energy efficient.
Any heater that has the Energy Star label will be very energy efficient. The Honeywell eco line, for instance, are very energy efficient.
yes, the Frigidaire FDF70S1 energy efficient
