We enable commercial building
owners to generate new income
from clean energy.

While technologies like solar, batteries, and energy efficiency improvements are increasingly affordable, the process of sizing, selecting, financing, permitting, and getting them installed has been confusing and painful. Lumen Energy applies technology and decades of expertise to make it simple. We do the hard work on behalf of building owners, and are here to help things go right over the long term. We offer personalized clean energy systems, under monthly energy subscriptions that deliver immediate value.

We build on decades of practical expertise deploying reliable onsite energy systems for buildings globally. Our core team has built technology products at companies like Google, Stripe, Intuit, and Shopify. Our team is global, with roots in San Francisco.

We don't have supercomputers, but our friends do. We collaborate with the brightest minds in building energy science at places like the National Renewable Energy Laboratory, Oak Ridge National Labs, and Lawrence Berkeley Labs.

When it's time to build, we partner with the very best installers near you. They know the local building inspectors, fire codes, and execute to permitted designs.
