Heat is always lost.
No not always necessarily, when energy changes form it usually is lost in the form of heat.

Total energy is always conserved. What is lost is that usually, some useful energy is converted into unusable energy - for example, heat that is spread out.
Usually some energy is wasted, yes. Energy is not "lost" in the sense of conservation of energy; energy is always conserved. However, useful energy gets converted into unusable energy all the time.

Heat is always lost.
Energy is never lost. It always transfers to something else.
thermal energy (heat)
light energy :) ANSWER: THERMAL ENERGY
Kinetic or potential energy are always present during energy transfers.
the simple answer no

well heres one easy answer to that- Just cut the freakin cables in half and you have lost your energy!
