With the expanding population, there is increase in an energy demand, which leads to the depletion of non-sustainable energy sources, for example; fossils. As the current situation speaks, the oil deposits are left for mere 53 years, likely with gas i.e. 52 years and with coal 150 years. So, there is an urgent need to find a sustainable source which is cheap and environment friendly, owing to the fact of current energy consumption level is left for merely 230 years.

... tive, for the future enhancement of the planet, the fossil fuel abandonment is required, and instigation of renewable resources such as Microbial Fuel Cell [MFCs] and Plant Microbial Fuel Cell [PMFCs] should be implemented. MFC is a visionary technique, as it converts wastage into the energy, whereas, PMFC is a new-fangled technique devoid of any climatic conditions and also it requires less investment. By scrutinizing this technique, Bacillus megaterium and sewage material is used in MFCs whereas Azolla and Trigonella foenum is used in PMFCs, which converts chemical energy into electrical energy with the help of electrons flowing from anode to cathode via circuit. The individual setup of each MFCs and PMFCs are examined diurnally for voltage and current gain proceeded by connection of both [MFC and PMFC] in series with LED in between thus gaining the luminance in LED. So assurance is gained by this technique of MFC and PMFC as distinctive energy harvesting technology equipped with; consistency, maintenance and free power for distant future.
