Abstract.
Energy is one of the basic ingredients required to alleviate poverty and socio-economic development. The energy prospect is generally assessed on the basis of available
commercial sources of energy i.e., fossil fuel like gas, coal, oil etc. Worldwide, there is a major transition underway in the energy sector. Biogas can be a potential source of renewable energy, Residues from biogas also proven as a significant source of organic fertilizer. If there is proper policy and implementation, Bangladesh’s energy crisis and organic fertilizer demand can be control through biogas plant.
1. Introduction
By 2020, the world is throwing into turmoil as demand for energy begins to greatly exceed the supply - crippling many economies and triggering widespread social unrest. Many countries in the West may experience a decline in living standards - with oil rationing and conservation measures introduced by governments and substantial reductions in travel, tourism and aviation. The crisis plays out for nearly two decades, gradually being resolved by a switch to renewable energy and alternative fuel technologies.
In Bangladesh context, neither the decision-makers nor the experts pay due importance on proper extraction and use of renewable energy. Here grater population is using natural gas and imported oil, with the present rate of consumption, natural energy resources like gas will be exhausted shortly and this is high time to derive policy and practice for exploration and use of alternative renewable sources if we want to meet energy crisis in near future. Biogas has been found to be a proven renewable energy option.
2. Biogas
Biogas, a cheap secondary renewable energy, is a gaseous fuel obtained from biomass by the process of anaerobic digestion or fermentation. Biogas
