12 Investors Predict Climate Tech’s 2026 Future

Contrary to widespread predictions of a downturn, climate tech investment has demonstrated remarkable resilience this year. Venture funding in the sector remained stable, defying expectations of a significant decline. This staying power stems from two powerful forces: the undeniable urgency of the climate crisis and the fact that many clean technologies are now either cheaper or more effective than their fossil fuel counterparts. The dramatic cost reductions in solar, wind, and battery storage serve as a powerful blueprint, proving that fossil fuels aren’t invincible and that substantial opportunities exist for funding cleaner, more economical alternatives.

Data centers continue to dominate the energy conversation, a trend investors unanimously expect to intensify in 2026. The insatiable electricity demands of artificial intelligence have created a powerful financial ecosystem. “They are creating their own financial ecosystem, and there is enough actual momentum in current AI efforts that I don’t see the hyperscalers pulling back in 2026,” observed Tom Chi of At One Ventures. The focus, however, is evolving. Lisa Coca from Toyota Ventures predicts, “The 2026 data center energy conversation is likely to shift from demand to resilience and the need to accelerate plans to decouple from the grid.” This move toward self-reliant power solutions aims to address growing public and regulatory pushback against grid strain and rising electricity costs.

The quest for reliable, clean power is fueling a renaissance in several generation technologies. Nuclear fission startups are particularly in vogue, having raised billions recently, with many eyeing public markets in 2026. Geothermal energy is also poised for a breakthrough, seen as a mature technology ready for larger-scale deployment. “Geothermal will be hot on solar’s heels in terms of new generation,” said Joshua Posamentier of Congruent Ventures. While these sources offer long-term solutions, solar and grid-scale batteries remain the immediate, cost-effective workhorses for meeting soaring demand, with new chemistries like sodium-ion poised to drive costs down further.

Investors are also looking beyond the AI hype to broader applications and necessary infrastructure. Reindustrialization—rebuilding domestic supply chains for complex systems like robotics and power electronics—will gain prominence. Grid modernization and execution have emerged as a critical, if less flashy, category. “The quiet winners are companies that make interconnection, planning, and deployment faster,” noted Amy Duffuor of Azolla Ventures. This includes software and hardware solutions that help utilities actually build projects, alongside physical innovations like robotics for burying transmission lines to mitigate wildfire risks.

Other sectors are attracting keen interest. Electric trucking, particularly with the anticipated release of the Tesla Semi, is seen as a potential industry disruptor. The intersection of AI and the physical world promises to transform manufacturing and logistics. Furthermore, technologies for climate adaptation and resilience are becoming urgent priorities. Perhaps the most contrarian view comes from Po Bronson of SOSV, who suggests that real breakthroughs often happen when investor enthusiasm wanes. “When investors finally get tired of a sector and come to the conclusion it won’t pan out, that’s when the real breakthroughs finally happen,” he remarked.

While the specter of an AI bubble bursting exists, most believe the underlying demand for power is fundamental and unstoppable. The spending for massive infrastructure is already committed. “The train has left the station,” said Kyle Teamey of RA Capital. The collective outlook from investors points to a sector that, far from dying, is entering a new phase of maturation, driven by hard economic realities and an urgent need to rebuild the world’s energy and industrial foundations.
