Energy Efficiency




 What is energy efficiency???

There is a "main energy" a device is trying to create. 
For a hair dryer - it is heat and wind
Then there are other energies that are there, but are not the main job of the device. 
(Ex: the actual spinning of the fan doesn't dry your hair - the wind it creates does. The sound that you hear isn't drying your hair, that just happens "on accident"). 

When more energy goes to the main energy -- it's more efficient
When less energy goes to the main energy -- it's less efficient
