FOREWORD The global energy system continues to undergo a profound transformation,with renewables as its driving force. Global renewable power capacityadditions continue to set new records, and renewable energy overtook coalto become the world's largest source of installed power capacity in 2025. Cost competitiveness remains the defining characteristic of renewable power.In 2025, more than 90% of newly commissioned utility-scale renewableprojects delivered electricity at a lower cost than the cheapest new fossil-fuel-fired alternative. Onshore wind remained the most affordable new powersource, with a global weighted-average levelised cost of electricity (LCOE)of USD 33 per megawatt hour (MWh), followed by solar PV at USD 44/MWhand offshore wind at USD 78/MWh. Meanwhile, gas-fired generation becamemore expensive, reinforcing the advantage of renewables over fossil fue
