Global renewable energy capacity must expand sevenfold to meet climate imperatives, IRENA reports

The International Renewable Energy Agency has outlined an urgent agenda for energy system transformation, calling for installed renewable power to reach 38.2 terawatts by 2050 as part of a coordinated global transition away from fossil fuels.
The International Renewable Energy Agency has released its 2026 World Energy Transition Outlook, presenting a comprehensive analysis of the systemic reforms required to realign the global energy transition with pathways compatible with limiting temperature increases to 1.5 degrees Celsius. The report emphasises that whilst renewable energy additions continue to establish new records, the acceleration of electrification powered by clean sources must become the defining priority for the decade ahead.
According to the analysis, global installed renewable power capacity must expand from the current 5.2 terawatts to approximately 38.2 terawatts by 2050. This expansion forms part of a broader transformation in which electricity’s share of final energy consumption would rise to 35 per cent by 2035, climbing to over 50 per cent by mid-century, with solar and wind sources providing more than 80 per cent of electricity supplies.
The report identifies a critical tension within the contemporary energy landscape: renewable capacity additions continue to accelerate, yet grid enhancements have failed to maintain comparable momentum, whilst global energy demand continues to surge with considerable velocity. Furthermore, energy efficiency improvements remain significantly below the rates required to offset expanding power consumption.
Francesco La Camera, Director-General of IRENA, articulated the essential shift in perspective required: electrification, grids, storage, flexibility and energy efficiency represent not peripheral elements but rather the fundamental backbone of genuine energy system transformation. He stressed that displacing fossil-fuel systems demands far more than simply introducing additional renewable capacity into existing infrastructure; it requires comprehensive reforms to construct an entirely new energy architecture.
The economic dimensions of this transition present compelling opportunities. Under IRENA’s 1.5-degree scenario, global economic output would expand by 1.1 per cent annually above business-as-usual projections, generating cumulative societal gains approximating USD 46 trillion by 2050. Employment within renewable energy sectors could increase more than fivefold from current levels exceeding 16 million positions, whilst increasing electricity market competitiveness could reduce end-user power prices by approximately 15 per cent by mid-century.
Realising this transformation requires substantial financial commitment. Cumulative annual investment must reach approximately USD 10.3 trillion across the 2026 to 2050 period, concentrated primarily in renewable power, grid modernisation, system flexibility and end-use electrification applications.
The report identifies seven priority actions for governmental implementation across the coming decade: integrated energy and market planning aligned with country-specific roadmaps; modernised grid infrastructure; strengthened industrial and investment strategies; advanced social and environmental policies designed to maximise transition benefits; and deepened international cooperation frameworks. Policymakers bear primary responsibility for orchestrating this transformation in a manner that preserves reliability, affordability and energy security whilst accelerating deployment of clean alternatives.
