Top Clean Energy Startups in 2026

Thank for you taking interest in our Startup, we are still keeping in Stealth mode and we will be launching the site and start Digital Marketing pretty soon. We at Ramanujan Inc, are creating an Advanced Energy Platform, which is first of its kind in the world. We are solving some key challenges faced by the Energy service providers and consumers. To put in a nutshell we are launching a) Connectivity from Device to enabling energy service for Utilities and Consumers b) APIs, for the length and breadth of Energy Sector over which various energy services, analytics and market place will be provided. The idea is already validated and extremely well accepted by the clients and we are in the process of signing up large deals based on our PoC and soon to be launched beta version. For the launch of platform we are looking for few key resources to work on the Platform. There are multiple reasons to look at our startup, some of them are – - Idea validated by customers and ready for commercialization - The best brains from Bay Area, who have played key role at Netflix, Apple, FB , Yahoo and Symantec’s are leading the technology - Includes stock Options Let me know if you are excited to discuss with us.

Enurgen builds DUET, a 3D physics-based software platform for utility-scale solar and battery storage. DUET simulates what a plant should produce at every timestep of a 30-year life, compares it against what the field actually did, and attributes the gap down to the individual component. Conventional monitoring can tell you a plant is underperforming — working out why is the hard part, and that's the problem we solve. Every megawatt-hour a solar plant fails to produce is one that comes from somewhere else. Recovering it needs no new land, no new panels, and no new interconnection queue — just a correct answer about what went wrong and where. The model came out of SUNLAB at the University of Ottawa, with more than a decade of research behind it. It runs across the asset lifecycle: - Design — terrain-aware 3D modelling to establish a realistic performance baseline before anything is built. - Construction — analysis from the moment equipment comes online, so issues surface before commercial operation rather than years into it. - Operations — minutely, string-level analysis with automated root-cause loss detection, separating recoverable losses from the ones that aren't and routing the fixable ones into the maintenance system. We're a small, early-stage team with an office in Ottawa, Ontario. The engineering work is heavy on data: analytical queries over fleet-scale time-series, streaming pipelines feeding live analytics, on-prem software that keeps running when the WAN doesn't, and dashboards that stay fast at that scale. Research sits at the same table as engineering, so the physics and the software get built against each other. Hybrid-first, with remote on the table for any role. Every role includes an equity grant. You don't need a solar background — the domain is interesting, our customers are sophisticated, and you'll pick it up.

We are Nevados Engineering, an innovative startup based in the Bay Area that is pioneering in the solar industry. At Nevados, we believe that solar installations should fit to the earth instead of forcing the earth to fit to solar installations. We specialize in designing and selling mounting systems, typically called Single Axis Trackers, and other related innovative technology to elevate the solar industry. Our core product, the Nevados “All Terrain Tracker”, is unique in that it enables installation on ungraded terrain which triples the amount of land available for developers, reduces construction costs, and reduces construction labor on flat, sloped, and rolling terrain.

kWh Analytics is the market leader in solar risk management. By leveraging the most comprehensive performance database of solar assets in the United States (20% of the U.S. asset class) and the strength of the global insurance markets, kWh Analytics’ customers are able to minimize risk and increase equity returns of their solar portfolios. kWh Analytics is backed by private venture capital and the US Department of Energy.

15+ years of leading the electric jet age. Our propulsors are the culmination of these years of research and development, resulting in the safest, quietest, most efficient electric propulsion technology now available. Whisper Aero is pioneering a more compelling and connected future by delivering cleaner, quieter, and more efficient propulsion solutions. Today’s open rotor propulsion systems are challenged by safety, noise, and performance limitations at all scales. Whisper’s breakthrough technologies allow aircraft to fly anywhere at any time without disturbing communities, at greater speeds, and with incredible improvements in efficiency and cost. Their innovations also enable a new generation of air moving products that can blend into the soundscapes of daily life. Whisper was founded by industry veterans, Mark Moore and Ian Villa, and continues to innovate a future that’s as considerate as it is compelling with its world-class team in Tennessee. We’re accelerating the adoption of everyday flight and looking for likeminded pioneers to join us on our journey. Whisper’s team brings together diverse perspectives with prior experience from Uber Elevate, NASA, and Northrop Grumman amongst many others. With a track record of maturing nascent R&D concepts to full-scale products, we’re keen to make ultra-quiet the new norm in aviation and beyond. We are always on the look for superstars. If none of these positions feel like a fit, but you feel strongly about our mission and our team, we encourage you to still connect with us and join our talent community! Chances are that we’ll have a role that might fit your experience in the future. We look forward to hearing from you!

Data centers and cloud providers consume 6% of the global electricity (more than India) and generate 4% of the global CO2 emissions (more than 2 times commercial air travel). They expect to consume 20% of the electricity worldwide by 2025. Submer (submer.com) develops a highly efficient, ultra-dense and eco-friendly, computing immersion cooling technology (submer.com/what-is-immersion-cooling) that saves 50% of this electricity, 85% of the real estate, and it can be placed anywhere, even without the expensive buildings. Making it also perfect for low latency applications and edge-computing. Submer has renown customers all over the world like some of the top 5 hyper-scale cloud providers, Airbus, the European Commission, the CERN Large Hadron Collider and more. Submer believes our digital world can be more efficient, cost-effective, scalable and eco-friendly. The Submer solution happens to be the best way to get there.
