The Energy Efficiency Formula: How to Calculate Energy Efficiency …
First, you need to measure the energy going into the system you''re evaluating, as expressed in watts or joules. Next, you need to measure the useful energy output of the system, as expressed in the same units of measurement. Then you take the energy output and divide it by the energy input. This is your energy efficiency ratio.
