Top Energy Efficiency Startups in 2027

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.

Skyven Technologies is an Energy-as-a-Service company which funds and de-risks capital projects to reduce carbon emissions caused by process heat.

TerraVerde Renewable Partners, LLC (“TerraVerde”) develops energy management programs and distributed solar generating facilities for local and state governments, school districts, non-profits and commercial real estate owners. We advise our clients on the project development process, performing quantitative cost-avoidance analyses, holding financing and procurement bid processes, overseeing project construction, and performing continued project management. Our energy management and solar energy facilitates allow our clients to replace traditional electricity purchases with a long-term, inflation-hedged energy supply.

Tetra is leading the clean energy transformation by adding transparency and efficiency into a forgotten industry. Home improvement contractors are left in the past, lacking automation and technology to run and scale their small business. This leaves homeowners without the necessary information to make easy, fast decisions and creates a painful buying process. Homeowners are unaware they can reduce carbon emissions and lower their utility bills. We provide the most efficient and affordable options to homeowners, improve their experience, and coordinate the installation of home improvement projects. In doing so, we're “super powering” contractors by automating admin tasks and allowing them to focus on installation excellence and customer happiness. We’re starting by transforming heating and cooling replacements, a $120 billion industry which makes up 12% of total energy usage in the US. Federal and state government agencies allocate billions of dollars in incentives to help homeowners choose high-efficiency systems—now at unprecedented levels thanks to the Inflation Reduction Act of 2022—but the dollars are historically underutilized due to lack of customer awareness. We’re democratizing and unlocking those incentive dollars. We started in Massachusetts, where we’re now 4%+ of the heat pump replacement market, and launched in New York in mid-2024, where we’re already seeing great traction, validating that our model has the potential to scale nationwide. With backing from the likes of Lerer Hippeau, Gutter Capital, Greycroft, and others, we’re now preparing to do exactly that.

Aeroseal is a creator of duct sealing technology aimed at lowering building carbon emissions. By sealing all the gaps in the building envelope, air ducts, and vents using the company's non-toxic, water-based compound, consumers can improve the comfort and health of their homes and workplaces while also helping to maintain a cleaner environment.

Crux OCM is a venture capital backed seed stage start-up on a mission to enhance control room operations in the $87.5 trillion dollar per year oil and gas industry to enhance safety and efficiency through autonomous capabilities. Although we are a young company, our team is comprised of industry veterans that have already made their mark in control system, commissioning, and advanced process control. In two short years we have progressed from concept, to MVP, to commercial-scale POC ‘s. Our key short term KPI is to add new logos via facilitating additional POCs. Crux OCM was born with the belief that control room operators should have better tools to perform their daily jobs. Control room operations directly impact safety, environmental, and bottom line revenue for energy operating companies. We thought, if pilots have auto-pilot software - why don’t control room operators? We are proud to help operating energy companies control rooms operate in the safest, most efficient way possi

Ultracapacitors with * 4x higher power density * 2x higher energy density than any competitor. This means we lower the costs 50-80% by using less materials, while at the same time offering our customers 2-4x smaller and lighter devices. This will solve crucial energy storage problems by re-generating energy, that would otherwise be lost, or providing peak or backup power in transportation, renewable energy, power quality and industrial sectors. Technology based on patented materials.
