Hey Mr? Whats efficiency mean?

    Heya there, Machine Whisperer back again, and pondering the idea of efficiency.  I often get asked to define efficiency and to help other folks understand what it means and why it matters. I hope this can clarify a bit more for those of you who have asked or just wondered about it.  
    We hear about fuel efficiency in cars, high efficiency washers and high efficiency LED lighting in the home- how does it all tie together?  Simply put, efficiency is the amount of energy you get out of a system compared to the amount of energy that had to be put in.  When we use energy in whatever form, some of it gets lost in conversion.
