An LED lightbulb has an energy efficiency of 89%. This means that 11% of the electrical energy that goes into an incandescent lightbulb is used to produce light energy.
Which statement best explains what happens to the other 11% of the electrical energy that goes into the lightbulb?
The leftover electrical energy is destroyed
The leftover electrical energy is transferred into heat energy
