An example of an energy efficient device includes an energy efficient light bulb.
The lower the amount of fuel the device uses to do a specific task the more efficient it is.
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.

Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
Energy efficient devices need not look much different to those that aren't. It really depends what device you are talking about, though.
To invite more efficient device, reduction in cost for products, easy maintanence and weights less device......etc......
carburetter
Even the best screws only have a mechanical advantage of twenty percent. Therefore, the screw is not a very efficient lifting device.
An electric heater ( the only known 100% efficient device ).
It depends on how efficient sed transportation device is
Yes, it is, as all the water that enters it, quickly flows out.
