Lithium-ion dominates the global clean energy transition. Africa's off-grid solar market still relies on lead-acid batteries. ETA explains why affordability, not technology, is keeping older battery chemistry alive, and what must change before households can switch.
Sub-Saharan Africa is now home to 563 million of the world's 655 million people without electricity, and the gap is becoming more concentrated. ETA Analysis examines what the 2026 SDG7 Energy Progress Report reveals about Africa's energy access challenge, and why current progress is still off track.
Africa recorded the world's fastest improvement in energy transition readiness in 2026. Yet grid reliability declined, infrastructure remained the weakest of any region, and system performance barely improved. ETA Analysis examines what the data actually shows.
Nigeria's solar expansion relies heavily on lead-acid batteries that typically fail within a few years. Yet nobody can say with confidence where most are recycled or disposed of. ETA Analysis examines the growing waste stream, health risks and governance gap behind off-grid energy access.
South Africa has opened the door to new oil and gas development. Guyana shows what happens next: growing dependence on hydrocarbon revenues, difficult policy trade-offs and shrinking room to change course. ETA Analysis on the risks policymakers should confront now.
Nigeria wants its most sensitive data stored at home. The problem is that data centres need reliable electricity, and the grid cannot consistently provide it. Vincent Egoro on the hidden energy challenge behind Nigeria's push for data sovereignty.
1,500+ Nigerian clinics are electrified. Vaccines still spoil. A new ETA policy brief identifies the market design failures — and three reforms NERC can implement now.
