Investment in solar-and-storage hybrid projects reached a record $25 billion in the first half of 2026 — nearly double the total recorded in the second half of 2025 and three times the amount invested in the first half of that year. This data strongly demonstrates that solar-storage integration has become the core growth engine of global renewable energy investment.
The United States and Australia led investment in this rapidly growing segment, setting benchmarks for the industry.
BNEF analysts note that this shift reflects an upgrade in how the industry values renewable energy assets — hybrid configurations offer operators the flexibility to store excess generation and dispatch electricity at more favorable times, delivering higher asset value and more stable returns.
The United States emerged as the second-largest renewable energy investment market globally, trailing only China but surpassing the European Union. US investment jumped 54% year-on-year as developers accelerated project financing to meet tax credit deadlines and respond to surging electricity demand, driven in part by data centers.
US solar investment rose 41% to a record $45.8 billion**, while wind investment more than doubled to **$13.8 billion. Projects that remain eligible for tax credits are expected to sustain construction activity through 2030.
Global renewable energy investment is increasingly characterized by greater diversification and balance across regions:
This diversified investment landscape demonstrates that the global adoption of renewable energy is accelerating, with more countries and regions joining the clean energy transition.
While global wind investment moderated year-on-year, bright spots emerged across key segments. Europe performed particularly well — Germany, Romania, and Serbia all recorded record investment levels following recent auctions, showcasing the region's strong commitment to energy transition.
Onshore wind maintained a robust fundamental position, with global investment reaching $80.7 billion, continuing to provide solid support for global clean energy supply.
BNEF anticipates that as market adjustments settle and hybrid project investment continues to accelerate, 2027 will usher in a new wave of robust growth. The solar-storage co-location model is rapidly becoming the new standard for global renewable energy investment.
The record investment in co-located solar-storage projects sends a clear signal: renewable energy is entering a smarter, more flexible, and more resilient new era. The industry is no longer simply about adding capacity but about building quality assets capable of efficiently navigating the challenges of modern power markets.
The global energy transition is an irreversible megatrend, and solar-storage integration will undoubtedly be one of the most promising growth forces in this journey.
