Solar-powered cookers improving the daily lives of communities in Rwanda

Coventry College researchers are easing entry to cooked meals in Rwanda by introducing solar-powered cookers to households with restricted power entry.

The cookers are a substitute for the normal firewood or charcoal stoves. The advantages embody improved air high quality in houses and lowered environmental influence by decreased deforestation and decrease emissions.

Round 30% of the world’s inhabitants lacks entry to scrub cooking amenities, whereas round 10% lack entry to electrical energy, with each disproportionately affecting ladies and kids. As energy systems grow to be extra reliant on superior digital applied sciences, underserved communities face heightened dangers of inequality.

A Photo voltaic Vitality Transitions (SET) venture led by Dr. Jonathan Nixon and Dr. Alison Halford from Coventry College’s Middle for Computational Science and Mathematical Modeling goals to bridge these gaps by co-designing solar-powered digital cooking programs in collaboration with the local people.

Working alongside trade and native power specialists Richard Mori from MeshPower, and Kabananiye Janvier and Habyarimana Cyprien from the Analysis and Improvement group at Rwanda Vitality Group, the analysis group put in photo voltaic digital cookers in 20 households.

Over seven months, the group monitored power use, air high quality and cooking habits utilizing greater than 100 sensors. Households considerably lowered firewood consumption, from 3.4 kg per day to only 0.86 kg per day, whereas kitchen air high quality improved by over 70%, contributing to more healthy dwelling environments.

Cooking instances additionally lowered considerably, releasing up hours beforehand spent gathering wooden or making ready meals. Group members of East Kayonza, an space the place many expertise power challenges, reported profound life-style enhancements, with one stating, “I no longer run in fields looking for firewood. We eat on time and children go to school on time.”

The SET venture enhanced community engagement by participatory workshops. This co-creation strategy has not solely fostered technological literacy but additionally amplified ladies’s roles as decision-makers within the design and improvement course of, so the top product responded and mirrored their particular wants and contexts.

Findings from the venture are already informing future e-cooking insurance policies and product improvement, whereas knowledge generated by the analysis are openly available for additional exploration.

Assistant Professor Alison Halford, co-investigator, Analysis Middle for Computational Science and Mathematical Modeling, mentioned, “Our findings demonstrate the tangible health, economic and environmental benefits that solar e-cooking can bring. This project shows the potential of clean cooking solutions to improve lives in even the most remote communities.”

Dr. Jonathan Nixon, principal investigator, affiliate director for analysis and engagement, added, “This project highlights how community-driven innovation can address global challenges like energy inequality and indoor air pollution. By working together with local households in East Kayonza, we’ve seen how solar e-cooking not only transforms daily life but also builds resilience and hope for a more sustainable future.”
