Concept of Energy Conversion

Energy is the ability to do work.

Energy exists in various forms. Some of these are:

  I ) Mechanical energy

  ii) Chemical energy

  iii) Light energy

  iv)  Electrical energy

  v ) Heat energy

  vi) Nuclear energy; and

   vii) Solar energy.

Energy can be changed from one form to another.

The two forms of energy from the sun – heat and light, exist naturally and can thus be used directly. Other forms do not occur naturally and have to be obtained by conversion from other types, for example, electrical energy has to be obtained by conversion from chemical, mechanical or heat energy.
