T-Mobile said it is using 100 percent of renewable energy for powering its mobile network by the end of 2021.

T-Mobile has developed a renewable energy strategy that includes eight virtual power agreements, 19 retail agreements, one Green Direct program, and unbundled Renewable Energy Certificates that support projects across the country.

“This was no easy task, but we set a goal and we achieved it. Today, thanks to amazing efforts from a team who was unwavering in our commitment to reduce our impact on the planet, the Un-carrier is powering America’s largest, fastest and most reliable 5G network with 100 percent clean electricity,” said Mike Sievert, T-Mobile CEO.

The company has invested in wind and solar power annually to account for every unit of electricity consumed. The nine large wind and solar farm projects alone (which include the virtual power agreements and Green Direct program) are contracted to provide T-Mobile with approximately 3.4 million MWh of clean energy annually — enough to provide electricity to over 313,000 homes per year.

Beyond agreements that directly contribute to T-Mobile’s energy matching efforts, the company also supports 37 community solar projects, which represent greening local energy grids with more than 2.1 million MWh over 25 years for Maine, Massachusetts, Minnesota, New York and Oregon.
