Nigerian households use a range of energy, from wood to solar – green energy planning must account for this

Nigerian households use a range of energy, from wood to solar – green energy planning must account for this

LOW and middle-income countries generally lack access to renewable energy and rely excessively on traditional fuels like firewood and charcoal. In these countries, 2.6 billion people depend mainly on polluting fossil fuels (for electricity) and traditional biomass fuels (such as wood or charcoal for cooking) to meet their daily energy needs. In sub-Saharan Africa, about 67% of households depend primarily on traditional biomass fuels. This heavy dependence exposes people (especially young children) in the region to particulate matter 2.5 (tiny specks of dust, dirt, soot or smoke that people breathe in). About 70% of the population is exposed to this…

Jobs or just lights? Nigeria toils to power up its solar promise

Jobs or just lights? Nigeria toils to power up its solar promise

RICE farmer Danjuma Okuwa knows what he needs to do to boost his profits: use a machine to remove the husk from his grain and then sell it directly to buyers at the local market, instead of supplying his unmilled harvest to a global agribusiness nearby. A 50-kilowatt solar minigrid system, installed in his rural community of Rukubi in Nigeria's central Nasarawa state a year ago, now makes that possible at an affordable cost. Rice farmer Danjuma Okuwa stands next to bags of harvested paddy rice at his compound in Rukubi, Nasarawa, Nigeria, September 27, 2022. Thomson Reuters Foundation/Afolabi Sotunde…

Africa’s green energy potential lures crypto miners

Africa’s green energy potential lures crypto miners

NOMADIC crypto miners in search of affordable energy are eyeing Africa, with Ethiopia emerging as a prime location for blockchain mining. This pivot towards the continent is driven by its abundant renewable sources including solar, wind, and hydroelectric power. Ethiopia, with its colossal hydroelectric dam, has seen an increased inflow of bitcoin miners especially from China, who are dodging Beijing's tight controls on crypto activities. China has cracked down on the activity due to its high energy requirements. Bloomberg reported that "19 of 21 electricity-supply deals for mining struck so far are with Chinese companies." China has become an important…

Africa’s solar mini-grid explosion

Africa’s solar mini-grid explosion

CONRAD ONYANGO, BIRD STORY AGENCY FOR the past two decades, many rural homes in Africa have relied on solar home systems to meet their basic power needs, like lighting a few bulbs, charging the family's mobile phones and powering small appliances like radios and televisions. Now, larger off-grid systems known as mini-grids (MG's) capable of powering bigger appliances - like fridges, flour and maize mills and even welding equipment - are increasingly being installed in rural communities. “The mini-grid space continues to attract a lot of attention from development partners… There are already many MGs in operation and many more…

Why wind and solar would offer the DRC and South Africa better energy deals than Inga 3

Why wind and solar would offer the DRC and South Africa better energy deals than Inga 3

GRACE C WU, Smith Conservation Fellow, University of California, Santa Barbara RANJIT DESHMUKH, Assistant Professor in the Environmental Studies, University of California, Santa Barbara SEVEN years ago the Democratic Republic of Congo (DRC) proposed the Inga 3 – a 4.8GW hydropower project on the Congo River – with great fanfare. Third, in a series of dams that would form the Grand Inga complex on the Congo river, the project was touted as a solution to southern Africa’s energy deficit woes and a way for the DRC to participate in regional economic development. Seven years later, development of Inga 3 has…

Solar keeps lights, phones on

KAGONDU NJAGI WHEN Lucyline Wanja Silas installed a 12-volt solar power unit at her home to help her children study at night, little did she know it would become essential to her and her neighbours in Gakunga village, central Kenya, during the coronavirus pandemic. Wanja, a 48-year-old farmworker, said she had not made any money since the country's lockdown started in March, but the solar photovoltaic (PV) unit she purchased in January means she no longer needs to buy kerosene for lamplight. And she can also help others in her area who are without electricity, either because of faults on power…
