    A brief review on renewable and sustainable energy resources in Bangladesh
    (Elsevier Ltd, 2021) Bhuiyan M.R.A.; Mamur H.; Begum J.
    The power sector in Bangladesh is dependent on fossil fuels like natural gas, furnace oil, diesel, and coal. In the fiscal year 2019-20, electricity generated in Bangladesh from natural gas about 71.82%, from furnace oil about 13.25%, from diesel about 0.20%, from coal about 4.16%, from renewable energy sources about 1.23%. Imported from the nearest country by having been connected to a grid line was about 9.34% of electricity within this year. A new record for the Bangladesh the power plants produced 12,893-MW (MW) electricity on 29 May 2019, the record-breaking generation took place against the forecasted demand of 14,796 MW. Generally, in the summer season, produced electricity cannot fulfill the country's demand as a barrier for industrial production and socio-economic infrastructure development. Overcome these problems the renewable energy sources can be more helpful for the electricity generation in Bangladesh. The government encourages people in rural areas to using renewable energy-based electricity like solar energy. Within the year 2021, they are planning to generate 10% of electricity from renewable energy sources. However, they have no success to generate a significant amount of total electricity from renewable energy sources in 2020. Herein, this review represents the present status, prospects, and update information about the renewable and sustainable energy source in Bangladesh. The review also discussed to provide the guideline for the government would successfully end their plan. © 2021 The Authors

    Thermoelectric generators act as renewable energy sources
    (Elsevier Ltd, 2021) Mamur H.; Dilmaç Ö.F.; Begum J.; Bhuiyan M.R.A.
    The thermoelectric generator (TEG) is a solid-state energy converting device that converts heat directly into electrical energy. TEGs are silent, scalable, and reliable, as they have no moving parts. The consciousness of surroundings pollution correlated with global warming has resulted in an upsurge of technological research to develop eco-friendly energy resources. TEG employs waste heat to generate power and thus can be the termed eco-friendly energy source. In the economic aspect, waste heat is a free source for generating electrical energy. It can handle the heat generated by the human body, computer chips, automobile engines, and industrial utilities. TEG used as a renewable energy source has been presented in this review article. It would help in the development of establishing a low-power solution and high-performance system. The present status, prospect, and update information about the TEG used as a renewable energy source has been discussed in detail. This review article also provides a recommendation, which system would be suitable for electrical energy generation by TEG through renewable energy resources. © 2021 Islamic University
