ABSTRACT
Information on energy wasting from a section of the book "Energy" is presented. It explains that one can measure how much energy is wasted by comparing the amount of useful work something does with the amount of energy in its fuel. It points out the energy efficiency of a bicycle, homes, and cars. It notes that the human body is only 25% efficient since most of the wasted energy is lost as heat. It is estimated that a light bulb wastes 90% of the electricity it uses by getting hot.
