At its most simple, wasted electricity.

Because they dont use supersonductiors, so pretty much 99% of energy is lost as heat

because there are resistance in conductors
P(power loss, or heat) = I^2(current squared) R(resistance)

-sigh- feeling like I'm being too negative lately

Because no conversion of energy from one form to another is 100% efficient.  This is why everything makes heat or vibration no matter what it is.  This is like, 10th grade science class material.

Joule's first law :

Q = I2*R*t

Where Q is the amount of heat , I is the intensity of the electrical current flowing through a conductor with resistance R , and t is the unit of time.

Don't kill an i7! Kill an FX instead!

Yeah umm you learn this in Physics....

Electronic uses energy, the energy won't be loss, it's just converted from one form to another form. 

So energy to heat.

Law of conversation of energy...

Is it possible to get 0 resistance?

No, but you can get pretty close using superconductors, but that's very expensive and a new technology.

As much as I understood, if it draws no power, it won't generate any heat.
