Comcast pledged Monday to double the energy efficiency of its vast national broadband system that funnels a torrent of cable and Internet data to millions of homes.

The Philadelphia-based global media and technology company said it plans to double the energy efficiency of its network by 2030, halving the electricity consumed per terabyte of data delivered. The pledge adds to Comcast’s goal set last year to reduce its net greenhouse gas emissions to zero by 2035 for direct and indirect emissions it owns and controls.

The engagement was timed to coincide with the opening of the Society of Cable Telecommunications Engineers exhibit at the Pennsylvania Convention Center. The annual SCTE Cable-Tec expo drew thousands of visitors before the event went virtual for the past two years due to the pandemic. This week’s event marks his return to a live venue. The company is based in Exton.

“We are on the path to a greener Internet,” Charlie Herrin, president of the technology, products and experience organization within Comcast Cable, said in a statement. “The intelligent technologies that drive our new network architecture are transforming the way data is delivered, providing the industry’s best combination of speed, coverage and control, all in a more sustainable way.”

Comcast, to underscore its commitment to sustainability, said it purchased renewable energy certificates to power the cable showroom with 100% renewable energy. Comcast is one of many companies that have touted their green credentials to meet their commitment to environmental, social and governance (ESG) criteria used by socially conscious investors.

The energy efficiency changes Comcast is making to its system will be invisible to retail customers. Comcast says it has been transforming its network to virtual cloud-based technologies that offer faster broadband speeds and greater reliability. The new virtualized platform includes more centralized locations for headends, hubs, and data centers that require less hardware, less space, and less power per byte.

From 2019 to 2021, Comcast said it improved energy efficiency by 30%.

The efficiency commitment covers only Comcast’s network and does not include set-top boxes in customers’ homes, those visible drains of electrical power in the home, even when the TV is off. New efficiency standards for set-top boxes took effect last year after environmental organizations pressured major cable providers to supply more efficient devices to their customers.
