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.
I would assume it means that the more efficient it is, the less energy it intakes and the more efficient the system is at retaining the energy it intakes.
Gas-fired, storage-based water pumps are the most energy efficient type.
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
A fan
A perfectly efficient machine, which doesn't exist in the natural world. The reason it doesn't exist is because any kind of work gives off energy byproducts (for instance, heat differential, friction, so on and so forth). Kind of like a perpetual motion device (which you could make by linking the outputs to the inputs on a perfectly efficient machine).ideal machine
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.
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
Most modern fridges are designed to be energy-efficient, meeting strict energy efficiency standards. However, older fridges may not be as efficient, leading to higher energy consumption. It's important to look for the Energy Star label when purchasing a new fridge to ensure it is energy-efficient.
