PHILADELPHIA—Comcast is reporting that it has reduced the electricity it takes to deliver each byte of data across its network by 36% since 2019. The 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 company said.
More specifically, Comcast decreased the electricity per consumed byte from 21.2 kilowatt-hours (kWh) per terabyte (TB) in 2019 to 13.6 kWh/TB in 2022. Ongoing investments in innovation, software, AI, and other virtual and physical critical infrastructure require less hardware, less space, and less energy per byte than previous technologies.
