Paris | October 10: In an important development for the worldwide energy transition, the International Energy Agency (IEA) confirmed that renewable energy technologies accounted for more than 85% of all new commercial electricity generating capacity added globally over the past year. Driven by falling manufacturing costs for solar photovoltaic panels, policy incentives across major manufacturing economies, and expanding grid-scale battery storage deployments, renewable generation outpaced traditional fossil fuel additions worldwide.
Solar Photovoltaics Lead Worldwide Additions Utility-scale solar installations accounted for the vast majority of the record growth, with distributed rooftop solar in residential and industrial zones also recording historic deployment rates across North America, Europe, and Asia. Technological advances in tunnel oxide passivated contact (TOPCon) and perovskite-tandem solar cells have increased electrical generation efficiency while lowering per-watt panel costs.
Simultaneously, offshore and onshore wind installations showed sustained recovery as supply bottlenecks eased and transmission projects were completed. Energy researchers noted that in multiple regional energy markets, generating electricity from new solar and wind installations has become substantially cheaper than maintaining existing coal and natural gas thermal power plants, driving market adoption independent of government subsidies.
Overcoming Modern Grid Transmission Bottlenecks Despite record additions in clean generation capacity, energy analysts warn that municipal power grid modernizations must accelerate to prevent renewable curtailment. National utility providers must invest in high-voltage direct current (HVDC) cross-border interconnections and large-scale battery energy storage systems (BESS) to balance intermittency and store daytime solar power for night-time peak demands.
International climate diplomats preparing for upcoming multilateral environmental summits emphasized that sustaining this rollout pace is essential to keeping international warming limits within reach. Global clean technology investments are projected to increase further into the coming fiscal year.
