From rot to revenue: How solar energy is cutting post-harvest losses in Nigeria's fishing village

The Barkum Women Rice Processors Association in rural Kano, Nigeria, secured a collective ₦8.8 million loan through cooperative action and training, enabling 38 women to build profitable rice-processing businesses that have financed their children's education and generated monthly incomes for members.

Solar-powered cold storage units operated through Farmer Producer Organizations in India have reduced post-harvest losses from as high as one-third of crops to minimal levels. This enables smallholder farmers to save on storage and transportation costs while gaining control over when to sell their produce at better prices.

A team of engineers at IIT Madras, a public university in India, has partnered with local utilities and the national Ministry of Power to bring sustainable, low-cost electricity to off-grid rural villages in the northwestern state of Rajasthan. With solar power supplied by DC microgrids, these poor rural communities are experiencing transformations to increase quality-of-life: affordable fridges that aid in food preservation, fans which mitigate heat and repel mosquitoes, and battery-powered phones connecting them to public emergency services.

In Dandabazar, a community-wide shift to commercial cauliflower farming was supported by local government seed distribution and subsidies for modern tools. This transformed a food-insecure hill village into a recognized vegetable-producing hub, enabling individual farmers to grow their businesses.

The SunZia project (a 916-turbine, 550-mile transmission wind energy system in New Mexico) now delivers up to 3.65 gigawatts of clean electricity to Arizona and California. Since testing began in April 2026, it's already driven record-breaking wind power generation five times on California's grid.

The failure of India's Zero Energy Cool Chambers to gain farmer adoption reveals that effective post-harvest storage solutions must match farmers' immediate cash needs, work across diverse climates with minimal maintenance, and points toward community cold storage with flexible rentals as a more promising approach.

Over 3,000 tribal farmers in Odisha are using the System of Rice Intensification (SRI)—an organic method that uses 92% less seed, no standing water, and traditional formulations—to double their rice yields, increase incomes, eliminate dependence on expensive chemicals and moneylenders, and revive 70+ indigenous rice varieties while improving soil health.

Sage Geosystems has developed a geopressured geothermal battery system in Texas that uses oil-drilling techniques to store energy underground for 4-6 hours—longer than lithium-ion batteries. This is one stage in a plan to replace an aging coal plant with renewable energy, though the system is not yet operational or connected to the grid.

Tribal nations across the U.S., supported by the Intertribal Buffalo Council and adaptive federal grants, have rebuilt bison herds totaling roughly 25,000 animals on tribal lands—restoring a critical food source, with programs distributing tens of thousands of pounds of buffalo meat annually to tribal communities.

The Perinjanam Solar Initiative successfully combined government subsidies, cooperative bank financing, and a community-governed consumer committee to bring rooftop solar to over 1,000 households. Altogether, this cut monthly electricity bills by up to 80% and reduced carbon emissions by 192,000 kilograms, however such initiatives have failed elsewhere in Kerala due to the absence of government mandates, standardized financing frameworks, and the political will needed to scale the model statewide.
