Top Clean Energy 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.

Acculon Energy is a one-stop shop for energy storage programs. Developing and deploying lithium batteries requires systems-level, full stack engineering expertise and broad capabilities to execute. Our 300,000 hours of battery program experience enable vehicle and battery OEMs to go further, faster, safer.

Solar loses up to 15% of generated electricity from the panel to the consuming device. If you store your solar energy in a battery and use it, it can lose an additional 10%. With the world's emphasis to move from fossil fuels to clean energy, throwing 25% of it away is crazy. Enteligent is focused on making solar electricity nearly lossless. We have higher efficiency products that can be used immediately along with future products that will dramatically improve our future energy preservation.
