Summary of Bracing for Climate Impact: Renewables as a Climate Change Adaptation Strategy

Core Content

This report, authored by Jinkyung Jeong and Hyun Ko of IRENA, examines the role of renewable energy in climate change adaptation and outlines a framework for integrating renewable energy into broader climate strategies. It highlights the growing recognition of climate adaptation as a critical component of climate action, alongside mitigation, and emphasizes the potential of renewable energy to provide both energy and non-energy services that enhance resilience to climate impacts.

Main Points and Key Information

1. Climate Change Adaptation: A Growing Priority

• Climate change is causing increasingly frequent and severe impacts, such as extreme weather events, temperature rise, and altered precipitation patterns.
• Adaptation is now a key pillar of climate response, alongside mitigation, with a growing flow of international and national finance directed towards adaptation.
• The Paris Agreement (2015) and other international frameworks, such as the Cancun Adaptation Framework (2010), have formalized the inclusion of adaptation in climate action plans.
• The concept of climate adaptation is defined as the process of adjusting to actual or expected climate changes and their effects, aiming to reduce vulnerability and enhance resilience.

2. Renewables as a Climate Adaptation Tool

• Renewable energy technologies (e.g., solar, wind, hydropower, bioenergy) are not only essential for mitigation but also offer significant potential for adaptation.
• Renewables can support energy-intensive adaptation measures (e.g., desalination, irrigation, air conditioning) with net-zero emissions, enabling "sustainable win-win" solutions.
• Distributed renewable energy solutions (DRES) are especially beneficial for vulnerable communities, such as those in coastal or rural areas, by providing reliable, affordable, and decentralized energy access.
• Renewables can deliver non-energy services that contribute to adaptation, such as solar shading, water harvesting, and organic fertilizer production.

3. Key Sectors for Renewables-Based Adaptation

• Water: Renewables can support desalination, wastewater treatment, and water pumping, particularly through solar and wind technologies.
• Food, Agriculture, and Forestry: Renewable energy can enable agro-photovoltaics, vertical farming, and reduce the need for deforestation by providing alternative energy sources.
• Natural Disaster Response: Renewable energy systems can provide rapid, reliable power during and after disasters, enhancing emergency response and recovery.
• Oceans, Coasts, and Small Islands: Renewables can help small island developing states (SIDS) address water security, coastal erosion, and energy access.
• Human Health: Renewable energy can support healthcare infrastructure, especially in remote or disaster-affected areas, by providing clean and reliable power.

4. Benefits of Renewables-Based Adaptation

• Reduced Vulnerability: By providing reliable energy access, renewables help communities withstand and recover from climate-related shocks.
• Enhanced Adaptive Capacity: Access to renewable energy improves the ability of communities to respond to climate change, especially in areas with limited infrastructure.
• Synergies with Mitigation: Renewables can simultaneously support mitigation and adaptation efforts, avoiding trade-offs and promoting integrated strategies.
• Multifunctionality: Renewable technologies can provide multiple benefits, including energy, water, and agricultural services, thereby contributing to sustainable development.

5. Planning and Financing for Renewables-Based Adaptation

• Many countries have incorporated renewable energy into their Nationally Determined Contributions (NDCs) and National Adaptation Plans (NAPs).
• As of 2020, 64 out of 190 countries had included renewable energy in their adaptation strategies.
• Climate finance for adaptation has increased, with the Green Climate Fund (GCF) allocating up to 50% of its portfolio to adaptation projects.
• Private finance is increasingly being leveraged through corporate environmental, social, and governance (ESG) practices, and green finance mechanisms are supporting the integration of adaptation and mitigation.

6. The Way Forward

• A holistic and integrated approach is necessary to ensure the effective deployment of renewable energy for adaptation.
• Cross-sectoral planning and stakeholder engagement are critical for identifying synergies, avoiding conflicts, and improving project outcomes.
• Renewable energy must be mainstreamed into short- and long-term decision-making processes.
• Monitoring, evaluation, and learning are essential to adapt to evolving climate risks and improve the effectiveness of adaptation projects.
• IRENA emphasizes the need for clear policy frameworks, financial support, and international collaboration to scale up renewables-based adaptation initiatives.

Conclusion

Renewable energy is a versatile and essential resource for climate change adaptation, offering both energy and non-energy services that can enhance resilience and sustainability. The report calls for stronger integration of renewable energy into national adaptation strategies, supported by robust policy frameworks, cross-sectoral collaboration, and innovative financing mechanisms. As climate risks continue to evolve, the role of renewable energy in adaptation will become even more critical for ensuring the resilience of vulnerable communities and ecosystems.
