Renewables Key to Energy Security Amid Global Supply Disruptions, According To IRENA

A new advisory from the International Renewable Energy Agency highlights renewable energy as a strategic solution to ongoing global energy market instability. Geopolitical tensions in the Middle East continue to disrupt oil and gas supplies, driving price volatility and affecting transport, food systems, and broader economic stability—particularly in energy-importing nations.

The agency emphasises that renewables are now central to energy security, not just decarbonisation.
In the short term, IRENA calls for the rapid deployment of decentralised renewable systems to protect critical services. Solar PV and battery-backed mini-grids can reduce reliance on diesel, particularly in remote and underserved areas. Governments are urged to fast-track permitting, remove trade barriers on clean energy technologies, and implement demand-side management to curb peak electricity use.

Over the medium term (six to twelve months), the focus shifts to grid resilience and flexibility. Continued investment in transmission infrastructure and modernisation is essential, despite inflationary pressures. Scaling battery storage, expanding demand response programmes, and integrating variable renewable sources such as wind and solar are key priorities. The advisory also highlights the role of renewable-based heating solutions, including heat pumps and solar thermal systems, in reducing gas dependence.

Looking ahead, stable policy frameworks will be critical to unlocking large-scale investment. Transparent regulation and clear procurement pipelines can help de-risk projects and attract private capital. IRENA also stresses the importance of developing regional supply chains for clean energy technologies to reduce import dependence. Any ongoing fossil fuel support, it notes, should be tied to measurable renewable energy targets.

The economics of renewables continue to strengthen. In 2025, around 692 GW of new capacity was added globally, bringing renewables close to half of installed power capacity. Solar PV costs have fallen by approximately 87% since 2010, while battery storage costs are down by 93%, making most new renewable projects more cost-effective than fossil fuel alternatives.

Countries including Spain and Portugal have improved resilience through wind and solar expansion, while China and Vietnam are reducing oil dependence via electric mobility.
IRENA concludes that renewables, electrification and storage offer the most reliable pathway to long-term price stability and energy security.
