PHILADELPHIA--(BUSINESS WIRE)--Jul 7, 2025--

Comcast today announced that it is on the cusp of reaching the company’s goal to double its network energy efficiency, well ahead of its 2030 target.

“We’ve known for a long time that the future of connectivity is more – more gaming, more streaming, more video conferencing, and, in recent years, more AI,” said Elad Nafshi, Executive Vice President and Chief Network Officer at Comcast. “We’re delivering dramatically more data at faster speeds and greater reliability at the highest quality for our customers, all while conserving the amount of energy needed to power our network. With an ambitious roadmap to meet growing demand, I’m proud of our leadership and progress on network energy efficiency.”

Comcast reported an 11% reduction in energy used to power the network and business from 2019 to 2024, leveraging leaner and smarter technologies that process more customer traffic with less electricity. At the same time, Comcast’s network traffic has grown by 76% from 2019 to 2024, meeting increasing customer demand for data fueled by streaming, gaming, sports, and business. The energy savings combined with network growth have resulted in a 49% reduction in electricity per consumed byte since 2019 – nearing the company’s goal to double network energy efficiency by 2030.

Comcast decreased the electricity per consumed byte from 18.4 kilowatt-hours (kWh) per terabyte (TB) in 2019 to 9.3 kWh/TB in 2024.

The efficiency gains have been achieved through Comcast’s ongoing nationwide network transformation to virtualized, cloud-based technologies that deliver faster broadband speeds and greater reliability with less equipment, less space, and less energy per byte.

“Our network is being transformed to enable customers to seamlessly connect to the AI revolution and to leverage it in their day to day,” Nafshi said. “At the same time, we are building in cutting edge network AI to optimize how we deliver our services with sustainability in mind.”

Comcast is embedding AI and machine learning throughout the network to improve diagnostics and make smarter network performance decisions. This includes enhanced monitoring and issue detection using bandwidth-efficient telemetry data as well as improved network maintenance using real-time issue localization plus predictive and self-healing network intelligence – actions that increase efficiency and improve the customer experience.

Comcast is also driving improvement through accelerated decommissioning of legacy equipment and enhancement of technical facilities – for example, through temperature set point optimization and improved air flow at datacenters.

“Driving energy efficiency is a natural evolution of how we meet growing customer demand and makes great business sense, especially as we make significant investments into our network and collaborate with suppliers to deploy the latest technologies,” said Ryan Capone, VP of Network Facilities & Energy at Comcast. “We've now laid the technological groundwork to deliver a fast, efficient, and reliable customer experience, while preparing to leverage AI to further drive efficiency in the future.”

Comcast’s Network Traffic Increased More Than 75% While Energy Efficiency Nearly Doubled Over Past Five Years

ADEN, Yemen (AP) — Saudi warplanes have reportedly struck on Friday forces in southern Yemen backed by the United Arab Emirates, a separatist leader says.

This comes as a Saudi-led operation attempts to take over camps of the Southern Transitional Council, or STC, in the governorate of Haramout that borders Saudi Arabia.

Tensions between Saudi Arabia and the UAE rose after the STC moved last month into Yemen’s governorates of Hadramout and Mahra and seized an oil-rich region. The move pushed out forces affiliated with the Saudi-backed National Shield Forces, a group aligned with the coalition in fighting the Iran-backed Houthis in Yemen.

Meanwhile, the Saudi ambassador to Yemen accused the head of the STC of blocking a Saudi mediation delegation from landing in the southern city of Aden.

The STC deputy and former Hamdrmout governor, Ahmed bin Breik, said in a statement that the Saudi-backed National Shield Forces advanced toward the camps, but the separatists refused to withdraw, apparently leading to the airstrikes.

Mohamed al-Nakib, spokesperson for the STC-backed Southern Shield Forces, also known as Dera Al-Janoub, said Saudi airstrikes caused fatalities, without providing details. The Associated Press couldn’t independently verify that claim.

Al-Nakib also accused Saudi Arabia in a video on X of using “Muslim Brotherhood and al-Qaeda militias” in a "large-scale attack " early Friday that he claimed sepratists were able to repel.

He likened the latest developments to Yemen’s 1994 civil war, “except that this time it is under the cover of Saudi aviation operations.”

Salem al-Khanbashi, the governor of Hadramout who was chosen Friday by Yemen's internationally recognized government to command the Saudi-led forces in the governorate, refuted STC claims, calling them “ridiculous” and showing intentions of escalation instead of a peaceful handover, according Okaz newspaper, which is aligned with the Saudi government.

Earlier on Friday, al-khanbashi called the current operation of retrieving seized areas “peaceful.”

“This operation is not a declaration of war and does not seek escalation,” al-Khanbashi said in a speech aired on state media. “This is a responsible pre-emptive measure to remove weapons and prevent chaos and the camps from being used to undermine the security in Hadramout,” he added.

The Saudi-led coalition in Yemen demands the withdrawal of STC forces from the two governorates as part of de-escalation efforts. The STC has so far refused to hand over its weapons and camps.

The coalition's spokesperson Brig. Gen. Turki al-Maliki said Friday on X that Saudi-backed naval forces were deployed across the Arabian Sea to carry out inspections and combat smuggling.

In his post on X, the Saudi ambassador to Yemen, Mohammed al-Jaber, said the kingdom had tried “all efforts with STC” for weeks "to stop the escalation" and to urge the separatists to leave Hadramout and Mahra, only to be faced with “continued intransigence and rejection from Aidarous al-Zubaidi," the STC head.

Al-Jaber said the latest development was not permitting the Saudi delegation's jet to land in Aden, despite having agreed on its arrival with some STC leaders to find a solution that serves “everyone and the public interest.”

Yemen’s transport ministry, aligned with STC, said Saudi Arabia imposed on Thursday requirements mandating that flights to and from Aden International Airport undergo inspection in Jeddah. The ministry expressed “shock” and denounced the decision. There was no confirmation from Saudi authorities.

ِA spokesperson with the transport ministry told the AP late Thursday that all flights from and to the UAE were suspended until Saudi Arabia reverses these reported measures.

Yemen has been engulfed in a civil war for more than a decade, with the Houthis controlling much of the northern regions, while a Saudi-UAE-backed coalition supports the internationally recognized government in the south. However, the UAE also helps the southern separatists who call for South Yemen to secede once again from Yemen. Those aligned with the council have increasingly flown the flag of South Yemen, which was a separate country from 1967-1990.
