Right this minute; a woman somewhere in rural sub-Saharan Africa is on a long trek. Not because she’s part of a nomadic tribe or visiting a neighbouring village but because she has to do something that many of us with modern conveniences take for granted – cook for her family. This woman represents the reality of about 3 billion of the world’s population who cook meals over an open fire everyday. People who just need an easier way to get things done. Showcased in the Network’s Solutions Database along with other low-tech projects, the Ezy stove does just that.
Kenya is a first in many a renewable energy innovation. The country houses a number of solar-energy innovations that touch on, among other sectors, agriculture and the retail sector. Agriculture, being the backbone of the Kenyan economy, and an employer of 75% or thereabouts of the entire country’s workforce, remains an important sector in the country. The IEA observes that by 2050, solar energy could be the top source of electricity, generating up to 16% of the world's electricity - Kenya is certainly not an exception to these statistics.
Living off the grid, without access to stable electricity, carries consequences beyond simply not being able to switch on the lights at night. In hospitals and clinics across developing regions, the inability to rely on electricity — or a complete lack thereof — translates into profound shortcomings in the provision of life-saving treatments. William Steel interviewed Julia Römer for Cleanleap, Julia co-founded Coolar in 2014, with the goal to develop a better solution for off-grid refrigeration of medical supplies.
Intasave, a not-for-profit and environmental enterprise is planning to use scalable nanogrid solar power systems to bring clean, reliable and affordable power to about 500 communities and 250,000 people in Kenya, South Africa and Mozambique within three years. After raising the initial US$100,000 through crowdfunding, construction of the hubs is already underway in villages in Kenya.
Smallholder farming is primarily characterized by differentially low incomes, in particular the poor sub-Saharan African farmers. Closely tied to this are the high proportion of farmers income spent on their energy needs, both at the domestic and crop-production level. There is essentially a correlation between income levels and access to clean modern energy. In Kenya, the energy situation could be getting better, with a social enterprise that invests in an end-to-end solution for smallholder farmers, Takamoto Biogas is tackling the fundamental global problems of deforestation and climate change.
In Kenya 17.3 million people lack access to clean water with water borne diseases like diarrhea and Cholera being the leading cause of death for children under five years. But a group of women have found a low cost method of purifying water, which is now backed by science - embracing seeds from the wonder tree Moringa oleifera.
In late 2004, Kisumu bay, Lake Victoria, was covered in a blue-green hue. The algal bloom - a proliferation of cyanobacteria – demarcated an area of low oxygen and eventually decomposing algae, causing fish to suffocate or flee and contaminating the drinking water- a dead zone. Adapt-N, a software programme developed by researchers at Cornell University seeks to solve this problem.
