100% renewable electricity.

Berry Gradient

We set a U.S. wireless first by joining the RE100 pledge and committing to source 100% of our total electricity usage with renewable energy by the end of 2021—a goal we achieved and have continued to maintain each year since.


Source 100% of our total electricity usage with renewable energy.

Through December 31, 2023, we have sourced 100% of our electricity usage from renewable sources and plan to continue to match future electricity consumption needs through renewable energy investments.

We’re going all in to mobilize for a thriving planet.

To change wireless for good, we must constantly look for ways to make sustainable choices that benefit our customers and the planet. Responsibly managing our energy use is an opportunity to make a huge difference for our environment and within our industry. Energy powers our entire business—including our Un-carrier network, our stores, our offices, and more. That’s why we’re committed to using energy more efficiently and sourcing it more sustainably.

When we source our electricity from renewable energy, like wind and sunlight, we know that not only will those sources never run out, but they also aren’t releasing harmful greenhouse gases in the process—and that’s good for people and the planet. Hitting our renewable energy goal is only one of the milestones on our path to building a more connected and sustainable future. And we won’t stop.

How do we achieve 100% renewable electricity?

Our energy comes from purchasing electricity from the U.S. electric grid, which is powered by a variety of energy sources, including renewable resources that are tracked using Renewable Energy Certificates (RECs). We are committed to funding the creation of new, clean power projects, including large-scale wind and solar farms—and acquiring RECs in a variety of ways. Our renewable energy portfolio included a mix of Virtual Power Purchase Agreements (VPPA), a green direct tariff, retail renewable agreements, community solar projects, and unbundled RECs to complement our energy reduction efforts.

Investing in renewable energy across the country.

Our VPPAs continue to make up a significant portion of our renewable energy work. One of the benefits of these investments is that our energy purchasing power is helping to drive demand for clean energy and bring more renewable energy to the U.S. power grid. We’ve also been growing our investment in community solar projects across the country.

The Un-carrier Network: Performance. Efficiency. Sustainability.

Our Un-carrier network uses up the biggest share of our total energy use. As we continue to expand our network footprint and improve performance, our energy team is continuously researching and designing innovative ways to boost its efficiency and optimize its operation.

As the data carried by our network continues to increase, we're rolling out more energy-efficient technologies, and our energy consumption per petabyte of data has steadily declined. Our low-band spectrum increases our service area, works better inside buildings than mid-band spectrum, and improves coverage, all while significantly increasing network efficiency.

And, we're implementing new technologies that reduce the demands of heating and cooling our cellular equipment.

We stand by our commitment.​​

Our goal is to achieve a 95% reduction in energy consumption (MWh) per petabyte (PB) of data traffic by 2030, from a 2019 baseline.​

​​We’ve achieved a 62% reduction in energy consumption (MWh) per petabyte (PB) of data traffic on our network since 2019, using 154 MWh per PB in 2023.​

Putting our energy into using less of it.

When it comes to optimizing our energy usage, we look at more than just our network—we are also driving reductions across our facilities. As we redesign and upgrade our buildings, we're installing energy-wise features, such as LED lighting, motion-activated lights, smart thermostats, and Energy Management Systems that allow us to make more data-driven decisions.


Building 2 of our Bellevue Campus has achieved LEED Silver® certification, which is an internationally recognized sustainability achievement that helps facility managers align buildings to a science-backed framework that prioritizes efficient use of natural resources, promoting sustainable materials, and enhancing human health. Plus, it's just really cool.
