Community development and energy equality: Experiences from micro hydro implementation in a tribal settlement in India

Mapping national information and communication technology (ICT) infrastructure to the requirements of potential digital health interventions in low- and middle-income countries

“…In the techno-economic studies of hybrid renewable energy that we identified across the five countries (Appendix 3 in the Online Supplementary Document), 47 studies reported the potential to generate 6.55-30 kWh/d off-grid electricity in rural areas, that could support digital health applications such as mHealth and a remote clinic as well as enable basic mobile signal transmission (see Appendix 3 in the in the Online Supplementary Document, 72-118 renewable energy category). By reducing energy insecurity, such schemes have multiple other socio-economic benefits for local households [34], mitigating electricity costs, greenhouse gas emissions, and (in Bangladesh) improving political trust [35].…”

Computational and Experimental Investigation of Runner for Gravitational Water Vortex Power Plant

“…Moreover, these plants have a common problem of very low utilization of electricity generation during off peaks hours resulting in the low plant factor. Using a Micro-Grid (also called local grid), the issue of loss of plant efficiency as a result of under-utilization of electricity generation during off peak hours can also be addressed [26]. The speed of rotation for this turbine is very slow at its maximum efficiency point, therefore matching it to a standard generator to produce 50 or 60 Hz output frequency will require a step-up in speed through either a gearbox or belt drive system.…”

“…Micro hydro is in most cases "run-of-river", with no dam or water storage, and is one of the most cost-effective and environmentally benign energy technologies to be considered for rural electrification. For economic viability of rural electrification, expansion of productive use of electricity is essential [26]. Studies in Nepal have shown that rural electrification alone has had minimal negative impact on agricultural or industrial production but has provided a cost-effective way to provide mechanical enduses to improve the lives of rural communities [7].…”
