As observed in day-to-day life, driving on a bumpy road generates vibrational energy in an automobile which is then dissipated by the shock absorbers. But lately, as we progress into the energy-depleting, energy concern awake era, energy efficiency has been a serious concern within the automobile manufacturing industry since the production within the 1900s, researchers realized that the energy dissipated in traditional hydraulic shock absorbers is merit being recovered only within the middle of 1990s. Unlike traditional suspension systems which suppress the vibrations by dissipating the vibration energy into waste heat, the regenerative suspension with energy harvesting shock absorbers can convert the traditionally wasted energy into electricity. Several different techniques followed for the energy harvesting are listed and Two main devices namely rotary and linear electromagnetic generators are analyzed for comfort and handling, body acceleration with and without a generator, and also attempts is made to enunciate the importance of energy conservation techniques in an automobile.
