In 2025, global investment in renewable energy reached a historic $1.5 trillion, marking a 20% increase compared to 2024, according to the International Renewable Energy Agency (IRENA). This surge is largely attributed to policy incentives, declining technology costs, and growing private sector commitments to sustainable energy.
Solar and wind power dominated new capacity installations, accounting for over 70% of all renewables added last year. The shift toward clean energy is accelerating universal access to affordable, reliable, and modern energy services, particularly in developing countries where off-grid solutions are expanding.
Despite this momentum, experts warn that investments must further scale up to meet the UN’s target of ensuring access to affordable, reliable, sustainable, and modern energy for all by 2030. Challenges remain in grid integration, energy storage, and ensuring equitable distribution of benefits. Policymakers and investors are urged to maintain ambitious climate-aligned energy strategies.
