Interesting Electrical Energy Facts:

  • Most forms of electrical energy in objects must be confined by wire when being used.
  • Lightning is an example of electrical energy found in nature.
  • Although electricity is neither a renewable nor nonrenewable source of energy, it often comes from both renewable and nonrenewable sources.
  • Electricity has been around for centuries but it was not until late 19th century that it was actually utilized.
  • Static electricity occurs when the electrons from one object jump to another object.

  • Electrical energy is the most widely used form of energy.
  • In order for electric energy to be utilized, it must act through a conductor.
  • Power plants that generate electrical energy actually change other forms of energy into electricity.
  • Electricity is generated when the electrons in a substance are passed along a conductor such as a metal wire.
  • Water, wind, and fossil fuels are all sources of electrical energy.
  • The two types of electrical charge in electrical energy are positive and negative.
  • If an object contains more electrons or negatively charges particles, it is said to be a negatively charged object.
  • When two charged objects are brought near each other, they either attract or repel each other which generate electrical energy.
  • Most of the time, electrical energy is viewed as power or the rate at which energy flows.
