One of the main drivers for adoption of biodiesel is energy security. Adoption of biodiesel eventually would help decrease a nations dependence on oil, and substituted with use of locally available sources, such as coal, gas, or renewable sources. While the total energy balance is debated, it is clear that the dependence on oil is reduced. One example is the energy used to manufacture fertilizers, which could come from a variety of sources other than petroleum. Cultivation of plants like Jatropha curcas in wastelands needs to be propagated further which would generate earnings for...

There is an increasing interest in alternative energy sources as the fossil fuel reserves like petroleum, charcoal and natural gas are limited and utilization of these fuels creates environmental pollution. The microbial fuel cell (MFC) is a new form of renewable energy technology that can generate electricity from what would otherwise be considered waste. In an MFC, bacteria are separated from a terminal electron acceptor at the cathode so that the only means for respiration is to transfer electrons to the anode thus converting chemical energy to electrical energy by the catalytic...
