Challenges related to energy shortages are increasingly frequent both at the local and global scale due to population growth and the desire for a greater standard of living. The growing demand for oil and natural gas caused by high consumption levels is one of the current major problems faced by the world population. Therefore, new forms of energy generation must be investigated that would eventually allow the diversification of the present energy matrix, which has an almost 90% dependence on fossil fuels the world over. This coupled with long-term economic and environmental concerns have resulted in a great amount of research in the past decades on renewable sources of liquid fuels to replace fossil fuels. Burning fossil fuels such as coal and oil releases carbon dioxide (CO2), which is a major cause of global warming. It is anticipated that not a single source of alternative energy but a mix of various energy sources and carriers will contribute to the energy system of the future. Among the various sources been explored, biogas offer one of the best alternative options as they present a viable option for improving sustainable development through energy security and reducing the emission of greenhouse gases. This paper elaborates on Biogas production as the alternative source of fuel. The paper also studies the importance of Biogas production as a means of reducing problem of power energy, environmental vandalism, loss of resources, climate change and also reduce environmental pollution caused by burning of woods, cars, motorcycle and industrial activities.
