There are several kinds of energy. Kinetic energy always involves motion. The push of wind, the vibrations of sound, a moving automobile, a spinning top all have kinetic energy because of their motion. The fundamental unit of energy in the metric system is the joule which is the energy required each second to push an ampere of current through an ohm of resistance.
Heat is the energy of molecular motion.
Silver is the best conductor of heat. If you stir a cup of hot coffee or tea with a pure silver spoon, the handle gets hot very fast. Styrofoam is one of the worst conductors, therefore it is used as a heat insulator. Ceiling fans fight convection by blowing the hot air back down to the living space below. Most of the heat we get comes from the sun by radiation.
