Abstract :
Limited amounts of fossil fuels and energy sources in addition to their high pollution potential, make it necessary to replace it by renewable sources. The contribution of this kind of energy in the world energy supply system is increasing. In order to worldwide sustainable development, International programs and policies including United Nations programs, has been assigned an essential role to renewable energy sources. So, new technologies inspired on nature, could be developed to produce electricity from sunlight by living plants action and photosynthesis. It’s based on cooperation and interaction between living plants, bacteria and a microbial fuel cell called Plant- MFC. In the Plant-MFC, living plants and bacteria were present to convert solar energy into green electricity. Microbial fuel cells could adsorb the energy produced from the reactions take place in rhizosphere by microbial actions and transformed it to the electricity. The main idea is that living plants produce rhizodeposites, mostly in the form of carbohydrates, and the bacteria convert these rhizodeposits into electrical energy via the fuel cell. This will not only provide the continuous use of solar energy in electricity generation, but also mitigate GHGs and other pollutants emission. In this article, the action of PMFCs in” green electricity” production from living plants, is explained.
