Summary of Key Points
Global energy investment continues to reach record levels (estimated at $3.4 trillion in 2026, with clean energy accounting for $2.3 trillion), yet the progress of energy transition has almost come to a standstill—the Global Energy Transition Index (ETI) increased by only 0.03% in 2026 compared to 2025. The critical issue lies in the "preparedness for transformation," which refers to the underlying conditions necessary to support the transition, such as policies, infrastructure, and an innovative environment. For the first time in over a decade, these factors have declined. Coupled with geopolitical conflicts, grid bottlenecks, and fragmented policies, the energy transition process has become fragmented: countries are progressing at varying speeds (Northern Europe leading the way, China and Asia ranking high, the United States declining, and Saudi Arabia standing out in the Middle East). Energy security risks have also increased, with deteriorating system reliability and supply conditions. The report outlines three key approaches to overcome these challenges: integrating safety and resilience into planning, upgrading grids, and using stable policies to guide capital towards emerging markets.
Detailed Analysis
1. More Investment, Yet Slower Progress?
Global energy investment is set to reach $3.4 trillion in 2026, of which $2.3 trillion will be invested in clean energy (renewable energy and nuclear power accounting for 42% of electricity generation, with nearly 800 gigawatts of new capacity added). However, this investment has not fully translated into tangible progress. The reason is simple: the underlying conditions are holding back the transition.
For example, grid congestion prevents the transmission of electricity generated by new wind and solar power plants; approval processes are too slow (it can take years to build a power station); trade barriers make it difficult to import essential equipment; and disruptions in supply chains due to geopolitical conflicts result in a shortage of raw materials. These issues have turned massive investments into an unfulfilled promise. Although the current energy system's performance has improved slightly (by 0.43%), the foundation for future transformation has weakened by 0.76%, akin to building a house with only bricks without a solid foundation.
2. Fragmented Global Transition
The pace of energy transition varies significantly among countries, resembling a uneven marathon:
- Northern Europe Leading the Way: Sweden, Finland, and Denmark rank among the top three, thanks to their robust infrastructure (capable of integrating large amounts of renewable energy), diverse low-carbon systems (wind, hydro, and nuclear power), and long-term stable policies (clean energy subsidies that have remained unchanged for decades).
- China and Asia in the Lead: China ranks 14th, with the highest investment in clean energy globally (US$627 billion in 2025) and the largest installed capacity of photovoltaic and wind power.
- India Making Rapid Progress: India has risen two places to 70th, as it has improved energy accessibility, increased energy efficiency, and accelerated the deployment of solar energy.
- The United States Declining: It has dropped from a previous high position to 19th; although its existing energy system (a mix of oil and gas and renewable energy) is still stable, frequent policy changes (such as new subsidies under the incoming government) and concerns about fossil fuel shortages have undermined the transition momentum.
- Divided Middle East: Most countries in the region are regressing, due to weak policies and significant infrastructure gaps; however, Saudi Arabia stands out, with a 1.5% improvement in its score, thanks to substantial investments in renewable energy and storage technologies and strong financial support.
- Regional Differences: Sub-Saharan Africa has made the greatest progress (more countries have adopted clean energy), while Latin America's readiness for transformation has weakened due to unstable policies.
3. Energy Security Warnings: Even Developed Countries Are Vulnerable
Energy security is the biggest risk factor, as it is the only indicator that has decreased (by 0.9%). This assessment focuses on three aspects: whether there is enough energy, the stability of supply, and the reliability of power grids.
The decline is caused by geopolitical conflicts and supply chain issues—events like the 2026 Hormuz Strait crisis, which threatened oil transportation routes, and the US-Iran conflict have increased the uncertainty of energy supplies. Even countries with mature energy systems, such as the United States and Iceland, have seen declines in their scores, indicating that no country is immune to these challenges.
Worse still, countries are adopting trade protectionist measures (e.g., restricting exports of essential equipment). In 2025, global trade restrictions amounted to $2.64 trillion, three times the level of 2024. Fragmented policies and markets have made the transition even more difficult to advance.
4. Three Steps to Overcome Challenges
The report proposes three solutions that need to be implemented simultaneously for effective results:
- Plan for Safety in Advance: Consider disaster resistance when building grids, rather than waiting until a crisis occurs; diversify energy supplies to avoid dependence on a single source.
- Upgrade Grids: Grids are the lifeline of energy transition; new renewable power plants must be connected to existing grids to be effective. This requires expanding grid capacity and improving integration capabilities (e.g., linking electricity from different regions).
- Use Stable Policies to Attract Capital to Emerging Markets: Emerging markets will drive future energy demand, but they often lack investment. Governments should introduce long-term, stable policies (such as subsidies and tax incentives) to encourage capital flows.
Countries that successfully implement these measures can turn the pressures of energy transition into competitive advantages in the complex global landscape. For example, mastering clean energy technologies will give them a foothold in future energy markets.
Conclusion
The global energy transition is currently facing three major obstacles: weak foundations, fragmented progress, and high security risks. Despite substantial investment, true acceleration of the transition requires addressing these underlying issues—stable policies, reliable grids, and secure supply chains. For ordinary citizens, this means that future energy prices and the availability of cleaner electricity will depend on how effectively these challenges are addressed.
