Capital Rebalancing Beneath the Surface of Resilience
Global energy transition investment is entering a new, more complex phase. According to GlobalData's latest report, "Energy Transition Investment Trends 2026," despite a tightening macro environment, policy fluctuations, and frequent supply chain bottlenecks, clean energy investment continues to show "resilience"—but this resilience is not linear; rather, it is accompanied by a significant rebalancing of capital across different technologies and regions.
"Although the growth rate has slowed compared to the early 2020s, investment continues to expand in both existing and emerging technology areas," noted Alex Phillips, GlobalData's energy transition analyst. Electrification, energy security concerns, and demand growth driven by AI and data centers constitute the core drivers of current investment. However, a counterintuitive phenomenon is that the same drivers are also fueling a revival of coal investment. "This proves that energy security does not automatically equate to clean energy," Phillips added.
Technology Tracks: Solar Deceleration, Nuclear Revival, and the Hydrogen Dilemma
In power generation technologies, renewables continue to dominate new investment, but the internal landscape is undergoing profound changes.
**Solar** remains the biggest magnet for capital, but its growth has become uneven and increasingly exposed to risks from highly concentrated supply chains (mainly dependent on the Asia-Pacific region) and policy shifts. In the latter half of this decade, solar investment growth is expected to slow noticeably.
**Nuclear** is showing a clear revival. Driven by rising demand for low-carbon baseload power—especially the thirst from AI and data centers for reliable clean electricity—nuclear investment is projected to increase significantly before 2030. Notably, the project focus is shifting from the Asia-Pacific region to Europe and the United States, with small modular reactors acting as a key catalyst. Phillips pointed out: "Data center demand has become a catalyst for new nuclear investment in North America, altering the locational logic for this technology."
**Biomass and geothermal**, long marginalized, have gained new attention in this round of transition. The Asia-Pacific region will remain the main driver of geothermal investment, but data center demand in North America has also sparked additional capital inflows, turning these two technologies into "small but beautiful" investment niches.
**Hydrogen** has the most complex investment outlook. Phillips describes it as "the most confusing," citing a huge gap between planned capital expenditure and actual project deployment. High capital costs and technological uncertainty expose hydrogen investment to extremely high execution risks.
Cost of Capital: A Wall Between Technology and Implementation"High interest rates increase borrowing costs, and energy transition technologies are typically capital-intensive, so they are particularly severely affected," Phillips warned. Interest rates not only push up financing costs but also transmit to emerging technologies through risk premiums: the higher uncertainty in execution and revenue for new technologies leads investors and lenders to price in higher risk, further raising the cost of capital. This dynamic is clearly visible in project cost expectations—especially for technologies still in their early stages, where cost reductions will be slower.
Regional Perspective: Asia-Pacific's Dominance Loosens, Europe and the US Rise in Nuclear Investment
Historically, the Asia-Pacific region (especially China) has been the absolute center of energy transition investment. But this landscape is shifting. The regional shift in nuclear investment is the most typical example: in the late 2020s, nuclear projects in Europe and the United States will increase significantly, while Asia-Pacific's relative share will decline. Small modular reactors (SMRs) are seen as a key technology for Europe and the US to reshape their competitive advantage in this field.
At the same time, the urgent demand for clean electricity from data centers in North America is driving a recovery in investment in geothermal, biomass, and even natural gas power generation from a policy perspective. Phillips expects that investment in natural gas power generation will rebound in the second half of the year, filling the gap left by the slowdown in renewable energy growth alongside nuclear power.
Outlook for 2030: Grid Modernization Becomes a Core Investment Priority
For the power generation industry, Phillips's primary advice is: "Treat transmission and grid modernization as core investment priorities." He points out that without increasing grid capacity, all the technology cost reductions discussed earlier "cannot be translated into reliable electricity on the system."
Looking ahead to the second half of this decade, renewable energy will continue to grow but at a slower pace; natural gas power generation investment will recover; nuclear investment will steadily strengthen. The capital flow of the entire energy transition is shifting from pure generation expansion to a system-level investment that coordinates generation, storage, and grid. Investment resilience remains, but the logic of capital allocation has shifted from a "scale race" to "quality and balance."
