<p>Energy crisis issue is appearing. The fact that there will no longer be enough unrenewable energy sources to fulfill global energy demand forces us to come up with some initiatives to overcome this. One way to do it is by trying to conserve energy in any way possible, such as in the production of reliable water sources. Microbial desalination cells (MDC) is one of the methods used in salt water desalination process. It runs on bioelectric potential produced because of the metabolism done by

... icrobes. The results of more recent findings shows that wastewater-based three-chambered MDC offers a new solution to resolve both issues concering energy and water crisis, also with higher efficiency than other common desalination process such as reverse osmosis, electrodialysis, thermal distillation, and freezing. Indonesia's nature as an archipelago country that is surrounded by enormous amount of salt water held the potential of MDC implementation to become a solution of energy crisis caused by the upcoming extinction of fossil fuel. <br /><strong></strong></p><p><strong>Keywords</strong>: Energy conservation; microbial desalination cells; seawater</p>
