Question

during every energy transformation, some energy is lost as heat. how does this affect the amount of electrical energy made by a power plant? energy output is less than energy input. energy output is more than energy input.

Explanation:

The law of energy conservation (and the concept of energy efficiency in energy transformations) states that energy is neither created nor destroyed, but during transformations (like in a power plant), energy is lost as heat. So the electrical energy output (energy made) will be less than the total energy input, because some energy is lost as heat and not converted to electrical energy.

Answer:

Energy output is LESS than energy input.
