In Bangladesh, despite available feedstock for producing biogas, the development of biogas production has been very slow. The objective of this research was to study the drivers for and barriers to biogas technology implementation in the country. As the research involved different types of stakeholders related to biogas production, the outcome provides clarity about the factors influencing the profusion of biogas production in Bangladesh. The outcome of the study identifies poor research and development, lack of coordination among stakeholders, an immature biogas market, lack of awareness and no feed-in tariff policy as the main barriers. In the case of drivers, the motivation of producing biogas as an efficient way of using waste, the availability of local experts, the attractiveness of a growing renewable energy market and the contribution of biogas technology in adaptation to climate change were found to be the most important factors. The study’s outcomes are found to be similar to other studies from developing countries with similar socio-economic status. In accordance with the important drivers and barriers identified in this study, recommendations for increasing the diffusion of biogas in Bangladesh are also presented at the end of the article.

Bangladesh faced a substantial growth in primary energy demand in the last few years. According to several studies, energy generation is not the only means to address energy demand; efficient energy management practices are also very critical. A pertinent contribution in the energy management at the industrial sector ensures the proper utilization of energy. Energy management and its efficiency in the textile industries of Bangladesh are studied in this paper. The outcomes demonstrate several barriers to energy management practices which are inadequate technical cost-effective measures, inadequate capital expenditure, and poor research and development. However, this study also demonstrates that the risk of high energy prices in the future, assistance from energy professionals, and an energy management scheme constitute the important drivers for the implementation of energy efficiency measures in the studied textile mills. The studied textile industries seem unaccustomed to the dedicated energy service company concept, and insufficient information regarding energy service companies (ESCOs) and the shortage of trained professionals in energy management seem to be the reasons behind this. This paper likewise finds that 3–4% energy efficiency improvements can be gained with the help of energy management practices in these industries.
