Environment devastation, global warming issues, energy security, and rising energy cost are among present energy challanges which stimulate renewable energy development. New sources for sustainable bioenergy production must be found. The Plant Microbial Fuel Cell (PMFC) generates electricity without harvesting the biomass. The PMFC can be applied in wetlands and generated up to 0.24W/m2 for-over two weeks. Recent research has shown that PMFC can be integrated in wetlands, potentially at large scale, producing electricity and protect the environment from devastation.
