Question

when energy is changed from one form to another, some of the energy is lost to the surroundings as waste thermal energy. the more steps needed to arrive at the desired energy or the more types of energy that are generated, the more energy is wasted. which object would likely have the least amount of wasted energy? a hairdryer a solar cell a car engine a hydroelectric dam

Explanation:

A solar - cell directly converts sunlight into electricity with relatively few energy - conversion steps, minimizing waste energy compared to a hairdryer (electrical to heat with losses), a car engine (fuel to mechanical with many losses), and a hydroelectric dam (water to mechanical to electrical with some losses).

Answer:

A solar cell
