Introduction to the Challenge

As the world grapples with the urgent need to transition to renewable energy sources, the G20+ countries have emerged as crucial players in this endeavor. These nations, which include the G20 members plus several additional countries in Asia and Central America, are not only significant contributors to global energy consumption but also major emitters of CO2. The International Renewable Energy Agency (IRENA) has emphasized that achieving the global goal of tripling renewable electricity capacity by 2030 hinges on the progress made by these countries[1][2].

The Importance of G20+ Countries

G20 nations alone account for 80% of global energy consumption and are responsible for over 80% of global energy-related CO2 emissions. This places them at the forefront of efforts to reduce emissions and transition to cleaner energy sources. The G20+ group, which includes countries like Malaysia, Philippines, Thailand, Vietnam, Cambodia, Laos, Myanmar, Singapore, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and Belize, must collectively provide as much as 80% of the total installed renewable electricity capacity by 2030 to meet global targets[1][2].

Current Progress and Challenges

Despite the importance of this transition, progress remains uneven across different economies. IRENA's data highlights that while renewables accounted for almost 90% of the world's total power capacity additions in recent years, more ambitious action is needed to achieve the 1.5°C goal. The agency stresses that bold policies, scaled-up investments, and innovative financial mechanisms are essential to overcome current barriers[1][2].

Key Challenges:

• Financing Gap: The need for significant investment to support renewable energy projects.
• Policy Frameworks: Strengthening regulatory environments to mitigate risks and ensure energy security.
• Technological Advancements: Further development of clean technologies like hydrogen and energy efficiency measures.

Recommendations for 2025

To keep the 1.5°C goal within reach, IRENA has outlined several priority actions for 2025:

• Electrification of Key Sectors: Developing grids, digitalization, and flexibility solutions for sectors like mobility, heating, and cooling.
• Direct Use of Renewables: Targeted investments and policy interventions for sectors such as shipping and aviation.
• Energy Efficiency: Doubling efficiency and advancing clean hydrogen technologies[1][2].

Science-Based Targets for G20 Countries

A recent report by The Foundations Platform (F20) and the University of Technology Sydney recommends that G20 states set ambitious renewable energy targets:

• Renewable Electricity Target: 70% by 2030.
• Renewable Final Energy Target: 60% by 2030.
• Renewable Heating Target: 55-60% by 2030[3][4].

These targets are crucial for ensuring that the G20 countries contribute effectively to limiting global warming to 1.5°C. Establishing legally binding targets can enhance investment security and encourage global financial support for renewable energy projects[3][4].

Conclusion

The success of the global renewable energy transition by 2030 depends heavily on the actions of G20+ countries. With their significant share of global energy consumption and emissions, these nations must lead the way in adopting ambitious renewable energy targets and implementing policies that support energy efficiency and clean technologies. As the world moves towards a more sustainable future, the commitment and progress of these countries will be pivotal.
