IRENA 2025 Renewable Capacity Report: Record Growth, But 2030 Target Challenging

• Global renewable power capacity reached record growth in 2025, adding 693 gigawatts, according to the IRENA 2025 renewable capacity report.
• Renewables were the most cost-competitive new electricity source in most markets last year, saving nearly half a trillion dollars in fossil fuel costs.
• Despite this progress, the world remains 0.6 terawatts short of the 11.2 terawatt 2030 goal set at COP28, even if 2025's growth rate continues.
• Energy efficiency improvements are lagging, and global energy demand, driven by cooling, AI, and data centers, continues to rise.
• Fossil fuels still supplied 86 percent of global energy in 2025, with their absolute use continuing to grow.

For legal professionals advising clients in the energy sector, particularly those involved in project finance, infrastructure development, or managing large-scale energy consumption, the insights from the IRENA 2025 renewable capacity report are critical.

The International Renewable Energy Agency (IRENA) recently released its 2025 renewable capacity report, revealing a significant surge in global clean energy deployment. The report, published as world leaders convened for the United Nations General Assembly amidst a summer of unprecedented Northern Hemisphere heat, highlighted that global renewable power capacity experienced record growth last year. This expansion underscores the accelerating shift towards sustainable energy sources.

Specifically, the IRENA 2025 renewable capacity report indicated that 693 gigawatts (GW) of new renewable power were added in 2025. This substantial increase represents more than half of the total installed electricity capacity across the entire United States, demonstrating the scale of recent advancements. Furthermore, the report confirmed that renewable sources maintained their position as the most cost-competitive option for new electricity generation in the majority of markets throughout 2025.

Simon Stiell, the Executive Secretary of the U.N. Framework Convention on Climate Change (UNFCCC), lauded these developments, remarking on the "brute power of market forces" driving an irreversible transition to clean energy. Speaking at the Industry Acceleration Summit, Stiell pointed out the substantial economic benefits, noting that global renewables prevented nearly half a trillion US dollars in fossil fuel expenditures. He characterized this as a "mammoth decarbonization dividend," exceeding the national Gross Domestic Product of over three-quarters of the world's nations.

Despite the impressive growth detailed in the IRENA 2025 renewable capacity report, the world faces a considerable challenge in achieving its ambitious climate objectives. A key target established at the COP28 talks in 2023 calls for tripling global renewable energy capacity by 2030. This translates to reaching 11.2 terawatts (TW) of installed capacity, a significant leap from the current 5.15 TW. To meet this goal, the world must more than double its present renewable energy levels.

The report projects that if the renewable energy growth recorded in 2025 continues at the same pace, global capacity would reach 10.6 TW by 2030. While this trajectory shows positive COP28 renewable energy targets progress, it still leaves a shortfall of 0.6 TW against the 11.2 TW target. Encouragingly, this gap has narrowed from the 0.9 TW deficit identified in the previous year's assessment, indicating improved momentum in renewable energy growth.

However, the International Renewable Energy Agency report also highlighted areas where progress lags. The world remains significantly behind on its objective to double the rate of energy efficiency improvements by 2030. To accelerate the global clean energy transition, IRENA provided several recommendations, including critical upgrades to electric grids and the integrated deployment of solar, wind, and battery storage systems to ensure continuous, cost-competitive power supply.

While the expansion of renewables offers a positive outlook, experts caution that this progress is tempered by rising global energy demand. David Waskow, director of the international climate initiative at the nonprofit World Resources Institute, emphasized that renewable sources are not yet displacing fossil fuel consumption at a sufficient rate. He identified two primary drivers for this increasing demand: the growing need for cooling in a warming climate and the escalating energy requirements of artificial intelligence and data centers.

This perspective is reinforced by findings from the Energy Institute's Statistical Review of World Energy, published in June, which reported that fossil fuels continued to supply 86 percent of global energy in 2025. Moreover, the review indicated that the absolute use of fossil fuels continued to grow. Waskow stressed the dual necessity of accelerating renewable energy deployment and electrification while simultaneously reducing fossil fuel consumption to effectively address climate change.

For legal professionals advising clients in the energy sector, particularly those involved in project finance, infrastructure development, or managing large-scale energy consumption, the insights from the IRENA 2025 renewable capacity report are critical. This report signals an increasing impetus for policy changes and evolving regulatory frameworks. Clients should anticipate heightened pressure for compliance requirements related to energy efficiency and renewable procurement, necessitating strategic monitoring of investment incentives and grid modernization efforts aimed at achieving the ambitious 2030 global clean energy transition goals.
