Sustainable Development Goal 7 (SDG 7) is all about ensuring access to affordable, reliable, sustainable, and modern energy for all. Energy is the heartbeat of human progress — from lighting up our homes and powering schools, to fueling industries and supporting hospitals. Yet, even today, millions of people around the world live without electricity, especially in rural areas of developing countries. This lack of energy access limits education, healthcare, economic development, and safety. SDG 7 focuses on changing that. It aims to increase the share of renewable energy in the global energy mix and improve energy efficiency by 2030. Clean energy sources like solar, wind, hydro, and geothermal are not just good for the environment — they also reduce air pollution, create jobs, and empower communities. But to achieve this goal, the world needs major investments, smart policies, international cooperation, and a commitment to leave no one behind. When energy is clean, affordable, and accessible, it fuels opportunity — lighting the way to a more sustainable and equal world for everyone.
