T-Mobilewants to celebrateEarthDay with environmental — and customer — friendliness. This week, the self-styled “Un-carrier” inked a long-term partnership with a renewable energy company that it says will reduce power consumption across its U.S. operations. And it’s doling out Earth Day benefits to customers who take advantage of its weeklyT-Mobile Tuesdaygiveaways.

T-Mobile is teaming up with Enel Green Power North America on its 300 MW Red Dirt wind project. The investment, which T-Mobile said is the largest wind power investment by a U.S. wireless company, is expected to generate approximately 1,200 GWh of renewable energy annually — equivalent to the energy consumption needs of more than 97,000 U.S. households. T-Mobile said it will “increase efficiencies” and “power the company’s operations” across the U.S., including retail stores, call centers, and network operations.

T-Mobile is no stranger to green projects. In 2010, it launched its first solar-powered cell tower in Chalfont, Pennsylvania. Cellular base stations comprise as much as 80 percent of all energy consumption from cellular networks, T-Mobile estimated.

“For Earth Day 2017, we’re thanking customers with green gifts and making it easy for everyone to do their part for the planet” John Legere, president and CEO of T-Mobile, said in a statement. “On top of that — this week’s T-Mobile Tuesday gifts make it easy for our customers to help with reforestation projects around the world — all it takes is a few taps on your smartphone.”

T-Mobile’s other T-Mobile Tuesday benefits include a $25 Restaurant.com gift card, a free Vudu movie rental, $5 off eco-friendly Lyft Line ridesharing, and 50 percent off premium Paper Culture recycled paper cards.

T-Mobile joins its carrier competition in promoting sustainability. AT&T releases annual details about its carbon emissions and reduction plans. And Sprint is promoting “green handsets,” “green buildings” and “green information technology,” and has further pledged to improve its device recycling rate to 90 percent by 2020.
