Explain different types of energy dissipation in energy transformation. How can these dissipation reduced ?

Energy is dissipated in three forms of energy. They are:

1. Heat energy: When work is done some amount of energy is wasted due to friction or air resistance in the form of heat.

2. Light energy: In burning some amount of energy is wasted in the form the form of light

3. Sound energy: In friction and collision some amount of energy is wasted in the form of sound.

The methods to reduce the dissipation of energy:-

1. The home appliances like TV, microwave, washing machine must be kept in standby mode when not in use

2. Buying appliances with more star ratings to reduce electric consumption

3. Using CFLs and LEDs instead of bulbs and tubelights to reduce the energy consumption

4. Making the walls of the rooms with heat resistors to reduce the energy consumption of air conditioners
