Electricity is much more important for the development of a country & its countryman. Electricity is the key to development. Most of the people in Bangladesh are migrating from rural areas to urban areas in search of a better life. As a result the demand of electricity in urban areas in Bangladesh is increasing day by day. But the Govt. has less alternative to meet up the huge demand of electricity in urban areas. In this paper a comparative study is taken to generate electricity from municipal waste which is also in an increasing rate in urban areas because of over population. By sorting out the municipal solid waste and through anaerobic process we can generate biogas which will lead to generate electricity. In this paper, this electricity generation process is described along with annual municipal waste data in different urban areas in Bangladesh to give a road map to the proper authority so that they may find it helpful to meet up the increasing demand of electricity in urban Bangladesh.
