An example of an energy efficient device includes an energy efficient light bulb.
Woodway Treadmills claim to be the most energy efficient.
LEDs are the most energy-efficient lights as of 2016.
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.

In recent years, LG appliances have been made to be energy efficient. LG claims that it's third generation refrigerator compressor is the most energy efficient in the world.
Any dishwasher that is Energy Star Rated is energy efficient.
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.
ATP is the most efficient molecule
Any heater that has the Energy Star label will be very energy efficient. The Honeywell eco line, for instance, are very energy efficient.
No, but it is one of the most energy-efficient cities in the United States.
