GerberSummary: The use of conventional forms of energy in Ghana has compounded problems for the Ghanaian economy due to unaffordability by both urban and rural poor, insufficiency or limitations due to the possible drastic fall of the water level of the Akosomo Dam. The Ghana Government Integrated Rural Energy and Environmental Project of the Ministry of Energy and Mines seeks to resolve these problems with the introduction of biogas generation in Ghana, as one of the alternative renewable energy sources to eliminate the problems in the forceable future. The anaerobic digestion of waste which yields biogas, is being utilised in Ghana for the following purposes: 1.generation of electricity for villages far from the National Grid; 2.Generation of gas for cooking as a better substitute for fuel wood; 3.Solving of sanitation problems; 4.Positive environmental measures, and 5.The prevention of massive loss of soil fertility and promotion of high yield of crops through the application of it's by product,"slurry", as an excellent,treated organic fertiliser. To talk of biogas is to talk of agriculture, since biogas generation starts with agricultural waste produce, such as cow dung, husk, straw etc. and ends with agricultural produce,- use of slurry on crops. Slurry is one of the most environmentally sound organic fertilisers in use today. It does not pollute the atmosphere during it's application and does not pose health hazards to the user and animals around. The paper presents the result of the study on the slurry.
