The International Renewable Energy Agency (IRENA) has warned that global renewable energy deployment remains behind the pace required to meet the target of tripling installed renewable power capacity by 2030. In its October 2025 assessment, released with the Brazilian COP30 Presidency and the Global Renewables Alliance, the agency highlighted a gap between record annual installations and the much faster expansion needed over the remainder of the decade. The findings indicate that growth in renewable generation alone will not be sufficient without coordinated improvements in infrastructure, investment and national policy commitments.
Global renewable power capacity reached 5,149 gigawatts (GW) at the end of 2025 after 692 GW was added during the year, representing annual growth of 15.5%, according to IRENA's April 2026 statistics. Although this marked another record, the 2030 objective requires capacity to rise to approximately 11.2 terawatts (TW). The difference between the current trajectory and the target highlights the scale of the deployment challenge: countries must sustain and accelerate additions rather than rely on the record growth already achieved.
IRENA's assessment identifies uneven progress across countries as a central concern. A large share of new renewable capacity is concentrated in a relatively small number of major markets, particularly China, the European Union and the United States. This concentration means that global totals can improve while many countries continue to face barriers to deployment, including limited access to affordable capital, inadequate grid infrastructure and insufficient project development capacity. The agency has called for more countries to establish clear renewable energy roadmaps and incorporate stronger targets into their national climate commitments.
Investment requirements remain substantial. IRENA estimated that average annual investment in renewable power generation across G20 and other key economies would need to exceed US$1.08 trillion between 2024 and 2030 to support the global tripling objective. For comparison, renewable power generation investment in G20 countries reached US$547 billion in 2023. Meeting the target will require greater mobilization of public and private capital, with governments, development finance institutions and industry coordinating to reduce project risks and expand financing opportunities, particularly in emerging and developing economies.
The agency has also emphasized that renewable generation targets cannot be achieved through solar and wind installations alone. Electricity grids, digital systems and flexibility resources must expand in parallel to accommodate variable generation and move electricity to areas of demand. Storage, improved grid planning and stronger interconnections can help reduce bottlenecks, while electrification of transport, heating and cooling can increase the use of renewable electricity. These supporting investments are essential to ensure that additional generation capacity translates into reliable electricity supply.
Progress in energy efficiency and clean technologies presents another challenge. IRENA's recommendations call for faster electrification across major end-use sectors, greater direct use of renewable energy where appropriate, and improvements in energy efficiency. The agency has also highlighted the need to advance clean hydrogen, electrolyzer deployment and other emerging technologies. These priorities broaden the transition beyond power generation and require governments to coordinate electricity planning with industrial, transport and building-sector policies.
The employment outlook illustrates another dimension of the transition. IRENA and the International Labour Organization reported in January 2026 that global renewable energy employment reached 16.6 million in 2024, an increase of 2.3% from 2023. This was the first reported slowdown in job growth despite expanding renewable installations. The agencies pointed to factors including geopolitical and geoeconomic pressures, automation and the concentration of manufacturing and deployment in a limited number of economies. The findings underline that rising capacity does not automatically produce employment growth at the same pace in every market.
For governments, the challenge is now to convert renewable energy ambitions into investment-ready programmes with measurable milestones. Stronger national targets, predictable policy frameworks, faster permitting, modernized grids and accessible financing will be important to closing the deployment gap. IRENA's findings show that the global transition is advancing, but the pace and distribution of progress remain critical to whether the 2030 tripling goal can be achieved.
