The 2025 report from the International Renewable Energy Agency (IRENA) showcases the significant impact of renewable energy on global energy access, with solar energy emerging as a key driver of this shift. The report highlights the rapid expansion of solar technology in developing regions across Africa, Asia, and South America, enabling millions of people to access electricity and improving their lives. Solar lights and Solar Home Systems (SHS) have been particularly successful, providing basic illumination and powering household equipment.
The widespread adoption of solar lights and SHS has been instrumental in expanding energy access, with small-scale solar lights providing basic lighting and larger systems offering more extensive power capacity. Solar mini-grids have also become crucial for community-level energy access, providing reliable electricity to entire villages. Beyond individual homes, solar energy is being used in various applications, including agriculture, health, and education. Solar water pumps are helping farmers irrigate crops more efficiently, while specialized solar systems are powering clinics and schools.
The IRENA report notes that regional trends show strong progress in Africa and Asia, with countries like Kenya, Ethiopia, and Tanzania reporting high numbers of people served by solar products. In Asia, nations like India and Bangladesh have large-scale off-grid solar operations, reaching millions of households. Even in areas with access to other renewables like hydropower, solar often acts as a faster and more flexible option, particularly in remote communities where grid extension is difficult or costly.
The report highlights that off-grid solar has become a central part of global energy strategies, providing clean, scalable, and affordable electricity. With declining costs and advancing technologies, solar power is improving health, education, and economic opportunities for millions of people worldwide. The ability of solar energy to provide reliable and quick power makes it a critical pillar in the pursuit of a sustainable and equitable energy future. Overall, the 2025 IRENA report demonstrates that solar energy is no longer a niche technology but a key tool for achieving universal energy access.
