Data were collected from 84 households under three household land categories – poor (land area &lt;0.10 acre), middle (land area 0.10-0.25acre) and well-off household (land area &gt;0.25 acre). Households were found to depend largely on biomass fuel including firewood, branches, leaves and twigs, bamboo, agricultural residue (rice husk, rice straw) and cow dung mainly for cooking. Firewood was the dominant biomass fuel for well-off and middle households (28% and 25%) and branches of the tree were dominant fuel for poor households (24%). More than 40% well-off households collect major amount of fuelwood from their own homestead forests while 32% middle and 37% poor households collect tree biomass from agricultural lands. Villagers preferred mostly <em>Albizia procera, Mangifera indica, Cocos nucifera, Tamarindus indica</em> as fuelwood tree species. Households across three categories (poor, middle, well-off) spend 19%, 12% and 11% of their total income for buying biomass fuels, respectively. All of the three households used a traditional wood-burning oven. Among them 39% well-off households and 18% middle households used LPG. Decreasing forest resources impose threats on the availability of biomass fuels. About 70% of households think that fuelwood was a scarce resource because of the degradation of homestead forest and fuelwood production unsustainability. Villagers suggested for alternative fuel items to decrease the pressure on biomass fuel energy sources. They also prescribed inclusion of fast-growing tree species into plantation program at the homestead level. Moreover, they demanded their involvement in this plantation program. The outcome of this study might be helpful to formulate policies to meet future challenges in fuel consumption and their sustainable utilization.</p> 2020-01-06T00:00:00+00:00 ##submission.copyrightStatement## http://journaljenrr.com/index.php/JENRR/article/view/30116 Techno-Economic Analysis of a Hybrid Mini-grid in Rural Areas: A Case Study of Bangladesh 2020-01-17T15:04:30+00:00 Tausif Ali tausif.ali@hhu.edu.cn Hongzhong Ma Ahmed Jaudat Nahian <p>A techno-economic analysis of a hybrid PV-Diesel mini-grid system in rural Bangladesh is presented in this study. The case-study is done using data from Patar Char village in Patuakhali district of Bangladesh, considering non-electrified households. HOMER simulation compares three system designs: Hybrid PV-Diesel-Battery, PV-Battery, and Diesel-Battery. Hybrid PV-Diesel-Battery system yielded optimum results in terms of the lower cost of energy (COE) of around USD 0.182/kWh. Overall carbon emission of this system is around 307 kg/year, which is lower than the Diesel-Battery system, but higher than PV-Battery system. A sensitivity analysis of PV-Diesel-Battery system is performed, by considering and varying some of the indicators to prove system sustainability and feasibility. The impact of price variability in diesel price, discount rate on COE, and total net present cost (TNPC) showed that PV-Diesel-Battery system is the most feasible option. Finally, a SWOT analysis is also presented to address participatory planning strategy of developing the hybrid energy system.</p> 2020-01-16T00:00:00+00:00 ##submission.copyrightStatement##
