An incandesent light bulb is only about 5% efficent (the light), the other 95% of the energy is wasted on heat.
Thats why the push for the world to change to the new coiled floresent bulbs.
They are over twice as efficent putting about 12% of the power to light using less power (a 20W floresent puts out as much light as a 75W bulb) and last 5 times longer.

A semiconductor is an "active" device, the "work" they perform is the millions of logic gates inside a chip being switched on and off millions of times a second and held in a given state (on or off) the entire time.

Resistors are a "static" device that simply restricts the flow of DC current by disapating it as heat (in series), or redirects the current flow (and voltage) when in parallel.

Nothing involving electricity is 100% efficient, not even wire.
Buy using better materials and using lower voltages semiconductors are becoming more efficient, but they always produce some waste in the form of heat.
