Energy efficiency is a metric that can measure the percent of inputted energy that is used by the system. If a system has poor energy efficiency, the output of the system will be much less than the input, and vice versa.
Typically, the more energy efficient something is the better. The optimal scenario is the same amount of energy that is inputted is outputted, getting as close to that as possible is best.
No, energy efficiency can only go as low as zero, it can not be any less than that.
With the current technology that we have, there is no system or thing that can have 100% efficiency due to many different environmental factors that currently can not be escaped.
If something is 75% efficient, it is capable of converting 75% of the supplied power to actually output work.
