An example of an energy efficient device includes an energy efficient light bulb.
A motor is one example of a device that converts electrical energy into mechanical energy.
One example is an electric motor, which turns electrical energy into kinetic energy.
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.
A glow stick is one example.
Same as a modern one. Thay are no more energy effecient.
An active device is a device that takes input energy to operate. The only energy a diode uses is from the signal applied to it (it has one input, one output, and no other terminals), so it is a passive device. To be an active device, a separate power source must be applied to it - such as the case for operation amplifiers, for example.
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.

one and one-half or two ton, depending on how new your unit is. older models are not as energy effecient.
A device that transmits energy from one device to another.
A device that heats a home by removing thermal energy from one location and transferring it to another location is a heat mover. An example of a heat mover is a refrigerator.
We transform energy because we need it in a specific form - either for the end-user device (for example, for the radio, we want sound energy), or to transport energy from one place to another (electrical energy is quite useful for this purpose).
