Is lost as heat
Entropy.
Ice melts in the hot sun
there is an increase in entropy in the universe.
Because of the Law of Conservation of Energy, when you transform energy, any amount of energy that gets lost as one type of energy must needs appear - in the same amount - as another type of energy.

Is lost as heat
heat. when there is transformation of energy from one form to another, there is a loss of heat energy. even when a form of energy is changed to heat energy, not all of the energy is transformed to heat, energy transformation is never 100%
In an energy transfer, the energy moves from one object/material to another. In an energy transformation, one form of energy transforms into another. In both, the amount of energy does not change, but in an energy transformation, some energy is lost into the environment.

Nothing. 1st Law of Thermodynamics: energy cannot be created or destroyed, it can only change form.
They should not, but in real life conductors transform some energy and this is called "loss". E.g., electric wire heats up when the current runs through it, a little bit of electricity is lost (due to wire's resistance) in form of heat. Transformation of energy should be kept as low as possible since any transformation in a conductor is unwanted.

The second law of thermodynamics states that energy cannot be changed from one form to another without the loss of usable energy. Enargy is usually lost in the form of heat. This law essentially means that energy changing forms is never 100% efficient.
