An anonymous reader quotes a report from Broadband TV News: The National Association of Broadcasters (NAB) has filed a petition with the Federal Communications Commission (FCC) urging the agency to establish a clear, industry-wide transition plan for the full deployment of Next Gen TV (ATSC 3.0). The proposal outlines a two-phased transition while modernizing regulatory requirements to support consumer access and innovation. [...] Under the plan, stations in the top 55 markets, covering 70% of the US population, would transition by February 2028, with all remaining full-power and Class A stations following in or before February 2030. The petition also calls for updates to FCC rules to ensure television reception devices support Next Gen TV, maintain existing MVPD carriage obligations and eliminate regulatory hurdles that could slow adoption. To clarify, ATSC 1.0 is the current standard for free over-the-air (OTA) TV. While ATSC 3.0 (also called NextGen TV) is its intended replacement, it's not backward-compatible, meaning consumers need new equipment to receive it. NAB's petition is to allow a complete shutdown of ATSC 1.0 to accelerate the transition to ATSC 3.0, meaning older TV setups relying on free OTA signals would stop working unless consumers upgrade their equipment. Their argument is that ATSC 3.0 adoption has been slow, and networks would benefit more from shifting away from OTA broadcasting entirely.

Reddit user bshensky argues that shutting down OTA TV would benefit large media corporations and harm independent stations. It's also worth noting that OTA TV operates on valuable spectrum, which could be repurposed for mobile broadband (this has happened before), benefiting cellular providers.

"Wind and solar energy generated more electricity in the U.S. than coal for the first time last year," reports the Wall Street Journal, "according to analysis from clean-energy think tank Ember.

"The two renewable energy sources accounted for 17% of the country's power mix while coal fell to a low of 15%, it said."

Solar was the fastest-growing energy source, according to Ember's analysis of data from the U.S. Energy Information Administration, increasing 27% from the year before, while wind rose 7%... Natural gas generation increased 3.3% in 2024, according to Ember, and remains by far the largest source of electricity in the U.S., accounting for 43% of the mix...
California and Nevada both surpassed 30% annual share of solar in their electricity mix for the first time last year (32% and 30%, respectively). California's battery growth was key to its solar success. It installed 20% more battery capacity than it did solar capacity, which helped it transfer a significant share of its daytime solar to the evening. Texas installed more solar and battery capacity than even California.

Yet the growth of solar was uneven — 28 states generated less than 5% of their electricity from solar in 2024, highlighting significant untapped potential — even before adding battery storage.
The article includes this observation from Dave Jones, chief analyst at Ember. "The fall in battery costs is a gamechanger for how much solar the U.S. electricity grid could integrate in the near future."

Electrek notes that "After being stagnant for 14 years, electricity demand started rising in recent years and saw a 3% increase in 2024, marking the fifth-highest level of rise this century..."

Natural gas grew three times more than the decline in coal, increasing power sector CO2 emissions slightly (0.7%). Coal fell by the second smallest amount since 2014, as gas and clean energy growth met rising electricity demand, whereas historically, they have replaced coal. Despite growing emissions, the carbon intensity of electricity continued to decline. The rise in power demand was much faster than the rise in power sector CO2 emissions, making each unit of electricity likely the cleanest it has ever been.
