Solar-Rich Nations to Dominate Global Energy Growth by 2035
Paris, Friday, 14 November 2025.
The International Energy Agency forecasts that countries with abundant solar resources will drive 80% of worldwide energy growth by 2035, reshaping energy markets and global economic trends.
The Rise of Solar Power
The International Energy Agency’s World Energy Outlook 2025 emphasizes that nations rich in solar resources are poised to dominate energy growth. By 2035, these countries will contribute to 80% of the global energy expansion, primarily through solar power. This shift is driven by technological advancements and substantial investments in solar infrastructure, indicating a rapid acceleration in the global energy transition [1][2].
Economic and Policy Implications
The anticipated growth in solar energy has significant implications for global economic trends and policies. As countries increasingly rely on renewable energy sources, the traditional energy market dynamics will shift, affecting energy security and economic stability. The report highlights the importance of updating infrastructure, such as transmission and distribution networks, which have lagged behind the rapid increase in power generation investments [1][3].
Challenges and Opportunities
Despite the promising outlook for solar-rich nations, challenges remain, particularly in enhancing grid capacity and storage solutions to accommodate the growth in renewable energy. The IEA notes that while investment in power generation has surged nearly 70% since 2015, spending on transmission and distribution has not kept pace, which could hinder the effective integration of renewable energy into the grid [1].
Broader Impact on Global Energy Policy
The transition to a solar-dominated energy market also impacts global energy policy, particularly concerning energy independence and sustainable development. Nations are now tasked with balancing energy security with environmental goals, and the IEA’s projections suggest that policies must adapt to support this transition. This includes fostering innovation in energy technology and addressing critical mineral supply chain vulnerabilities, which are essential for clean technology and energy systems [2][3].
