About

Rahul Iyer grew up in Chennai and studied electrical engineering before completing a postgraduate diploma in development economics in London. His career sits at the intersection of energy technology and global equity — a space he believes is critically underreported. While most energy journalism focuses on the transition happening in wealthy nations, Rahul writes about solar microgrids in rural India, clean cooking technologies in sub-Saharan Africa, and the innovators building energy systems for people who have never had reliable power. He is convinced that the clean energy revolution's most important stories are not being told in the places where they matter most. He lives in London and travels regularly across South Asia and East Africa.
