The new virtualized platform includes more centralized locations for headends, hubs, and data centers that are more efficient than previous technologies, requiring less hardware, less space, and less energy per byte.

These efficiency gains are a critical part of our plan to grow the Xfinity 10G Network more sustainably and put us on the path to a cleaner, greener internet.
Charlie Herrin
President of the Technology, Product, Experience organization within Comcast Cable

Comcast decreased the electricity per consumed byte from 18.9 kilowatt-hours (kWh) per terabyte (TB) in 2019 to 12.1 kWh/TB in 2022, reducing the electricity it takes to deliver each byte of data across its network by 36%.

These efficiency gains have been achieved through a reduction in total energy use across network facilities and operations while at the same time delivering more data, faster broadband speeds, and greater reliability.

The network has an essential role to play for the planet. Driving energy efficiency across the business and sourcing more clean and renewable electricity are paramount to achieving our climate goals.

Comcast has set a goal to be carbon neutral by 2035 for Scope 1 and 2 emissions, or the direct and indirect emissions it owns and controls, across its global operations. With purchased electricity accounting for the majority of its emissions, Comcast is investing in clean, renewable energy to power its network and operations, as well as shifting to newer, more energy-efficient technologies and facilities to deliver more data with less energy per byte.
