January 15th through the 21st marks Energy Saving Week in the U.K., but its message can be applicable worldwide.
When did this observance begin? Who created it?
This campaign was established in 2008 by the Energy Saving Trust and Citizens Advice Bureau, aiming to bring awareness to energy saving in the United Kingdom.
What is energy?
Energy is defined as “power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.” (Oxford Dictionary). Energy surrounds us, especially in a modern world of technology that uses so much of it.
What types of energy are there?
Energy can be in two broad categories, kinetic and potential. There are various types:
Thermal: refers to the energy contained within a system that is responsible for its temperature
Electrical: energy transferred as electric charges move between points with different electric potential
Chemical: the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances
Radiant: the energy of electromagnetic waves
Nuclear: energy in the core of an atom
Light: a form of electromagnetic radiation of a wavelength, which can be seen by the human eye
Motion: the energy stored in moving objects
Elastic: energy stored in an object when there is a temporary strain on it
Sound: movement of energy through a substance – such as air or water – in the form of waves
Gravitational: energy an object possesses because of its position in a gravitational field.
