Africa Urged to Accelerate Energy Transition as Renewables Set New Global Record
The International Renewable Energy Agency (IRENA) has released its Renewable Capacity Statistics 2026 report, revealing that global renewable energy capacity surged to a record 5,149 gigawatts (GW) in 2025, following an addition of 692 GW. This growth underscores the increasing dominance of renewables, which accounted for 85.6 per cent of total capacity expansion worldwide, amid ongoing geopolitical tensions that highlight the vulnerabilities of fossil fuel-dependent systems.
Renewable Energy as a Path to Security and Resilience
IRENA emphasizes that renewable energy, being locally sourced, cost-effective, and rapidly deployable, offers countries a robust pathway to greater energy security and resilience. Francesco La Camera, Director-General of IRENA, noted that in these uncertain times, renewable energy remains consistent and steadfast in its expansion. He stated that nations investing in clean energy are better shielded from global shocks, benefiting from improved competitiveness and reduced exposure to volatile fuel markets.
Solar and Wind Lead Global Expansion
Solar energy led the global expansion, contributing 511 GW, which represents approximately 75 per cent of all renewable additions, largely driven by solar photovoltaics. Wind energy followed with 159 GW, meaning these two technologies together accounted for nearly 97 per cent of new renewable capacity in 2025. Other sources, such as bioenergy, hydropower, and geothermal energy, recorded comparatively modest growth.
Regional Disparities Highlighted
Despite global progress, the report highlights significant regional disparities. Asia dominated the renewable energy landscape, contributing 74.2 per cent of new capacity, with China alone responsible for a substantial share of solar and wind additions. Europe maintained its position as the second-largest region, while Central America and the Caribbean lagged behind.
Africa's Growth and Challenges
For Africa, the report shows that the continent recorded its highest-ever annual growth in renewable capacity, rising by 15.9 per cent with an additional 11.3 GW. This growth was largely driven by countries such as Ethiopia, South Africa, and Egypt. However, Africa's overall share of global renewable capacity remains marginal, underscoring persistent structural challenges including limited financing, weak infrastructure, and policy inconsistencies.
Nigeria's Slow Pace of Transition
While Nigeria had planned to ban solar imports, the report reinforces long-standing concerns about the country's slow pace of energy transition despite its vast renewable potential. As one of Africa's largest economies, Nigeria continues to rely heavily on gas-fired power generation while struggling with chronic electricity shortages. Stakeholders argue that scaling solar and off-grid solutions could significantly improve energy access, particularly in rural communities.
Off-Grid Renewable Growth
The report also notes growth in off-grid renewable electricity, which is critical for underserved regions, adding 1.7 GW globally, mostly from solar. This is particularly relevant for sub-Saharan Africa, where millions still lack access to reliable power, highlighting the urgent need for accelerated investment and policy support to bridge the energy gap and foster sustainable development across the continent.
