In today’s fast-growing world, the rate of energy consumption is rising at unexpected rates with each passing day. Ethiopia has also part of this global trend particularly over the last decade. To meet its growing energy requirements, the country has been investing hugely in developing its hydroelectric power generating capacity from water source like Gelgel Gibe dam, Abay River dam, Fincha dam and the like. Besides, the country also relies substantially on the fuel it imports to meet its energy demand. Development of renewable and sustainable energy source is the best solution to the country’s energy demands. It is much desirable that the renewable energy to be developed has no adverse effects on the environment. Surely, productions of renewable energy from materials that are readily and locally available are extremely advantageous and reduce the cost of its production. Environmentally friendly individuals may choose to compost their food waste to acquire a useful fertilizer or soil amendment; however, this process does not allow a means to capture the energy that is locked up in waste.
