Interesting Facts About Energy

Interesting Facts About Energy




The use of the word ‘energy’ dates all the way back to the 4th century BC. The word energy comes from a Greek word ‘energeia’ which means ‘activity’. We use energy to do everything. There are numerous types of energy but they can be classified into 2 main types namely potential energy and kinetic energy. Potential energy is energy stored in an object when it is at rest whereas kinetic energy is energy in motion.

Most types of energy are either a form of potential energy or kinetic energy. Some common examples of energy include elastic potential energy, chemical energy, heat energy, nuclear energy, geothermal energy, sound energy, and gravitational energy. Energy can neither be created nor be destroyed, it can only be transferred into one form to another. Some interesting facts about energy are given in the points mentioned below.

  • Energy is usually measured in a unit called as joule.
  • During the process of photosynthesis, plants use energy from the sunlight.
  • During a chemical reaction, the chemical energy is often transformed into heat or light energy.
  • When energy or power is generated from moving or running water, it is known as hydropower.
  • When an object is stretched, for example, a trampoline or a rubber band, energy is produced.
  • Solar energy is produced when the sunlight is transformed into electricity.
  • A wind turbine is used to convert the wind energy into other forms of useful energy like electricity.
  • The largest solar power plant in the world is located in the Mojave Desert in the United States of America.
  • Nuclear power plant produces around 13% of the world’s electricity
  • Food gives us energy. Some foods give us more energy more than other food.
  • 83% of the world’s air pollution comes from the production and use of electricity.
  • A heavy coat of dust on a light bulb can block up to half of the light.
  • Refrigerators account for 7% of the nation’s total energy use.
  • Compressed springs and stretched rubber bands are examples of elastic potential energy.
