- Maintenance : Appliances using electrical energy are robust, smaller in size and need little maintenance.
- Illumination : The light provided by a bulb or fluorescent tube is greater than the light obtained from a candle, kerosene lamp or petromax.
- Magnet : Electromagnets are more stronger and powerful than other magnets
- Heating of non-conducting materials : Uniform heating of non-conducting materials such as bones, drying textiles, etc., is possible only with the help of electrical energy.
- Storage battery etc.: Electrical energy has made it possible to have electroplating, electrotyping and storing electricity in the form of chemical energy in storage batteries.
