Answer:
True
Explanation:
An efficiency rating refers simply to how efficient a machine is at using energy to do what it is supposed to do. Basically, you would divide the energy output by the total energy consumption. For example, a perfect efficiency washer would use 100% of the energy used to wash clothes. However, due to several reasons, machines cannot reach 100% efficiency but you can have higher efficiency ratings. While these machines may be more expensive upfront, overtime they end up saving money since they consume less energy to do the same amount of work as lower efficiency rated machines.
