"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.

An anonymous reader quotes a report from Fortune: Younger Americans don't have enough saved to cover a single month of spending, showcasing their vulnerability should the economy head into a downturn. Members of the Gen Z generation -- people born after 1995 -- were spending twice the amount they had in savings on average in February, according to Bank of America Institute analysis of internal account and card data released Friday. The ratio has increased in the past two years, and is much higher than for other generations. In part that's because Gen Z consumers, many of whom still hold entry-level positions and make less than their older peers, tend to spend a bigger share of their incomes on necessities including rent and utilities. But they're also more likely to shell out on discretionary categories like travel and entertainment. Spending in non-essentials among that cohort is up more than 25% from a year ago -- substantially above the overall rate.

While the report noted that Gen Z workers are still garnering robust pay gains compared to older groups, it showcases a point of vulnerability as households' views of the economy dim. [...] The Bank of America report also pointed to a worsening labor market for younger Americans. The number of Gen Z households receiving unemployment benefits rose by nearly a third in the past year -- the most of any generation. It also noted that, with underemployment on the rise, that could have long-term career effects for that cohort.

The US government's tariff announcements have become a "big headache" for technology companies such as iPhone maker Apple and cloud service provider Amazon, their manufacturing partner Foxconn said on Friday, in a rare public admission of the disruption caused by President Donald Trump's erratic trade policy. Financial Times: "The issue of tariffs is something that is giving the CEOs of our customers a big headache now," chief executive Young Liu told investors on an earnings call. "Judging by the attitude and the approach we see the US government taking towards tariffs, it is very, very hard to predict how things will develop over the next year. So we can only concentrate on doing well what we can control."

Liu said the company's customers were "one after another" hatching plans for co-operating with Foxconn on manufacturing in the US. He declined to give details as those plans were not yet finalised, but said there should be "more and more" manufacturing in the US.

Breakthrough Energy, the climate group founded by Bill Gates, has laid off dozens of employees in the U.S. and Europe, eliminating its public policy and partnerships teams as it shifts away from advocacy work. Its investment and grantmaking divisions will remain unaffected. The Detroit News reports: Breakthrough Energy is an umbrella organization founded by Gates that houses various initiatives aimed at accelerating the clean energy transition. It also encompasses Breakthrough Energy Ventures, one of the biggest investors in early-stage climate technologies with stakes in more than 120 companies, as well as a grantmaking program for early-seed stage company founders and Breakthrough Catalyst, a funding platform focused on emergent climate technologies. None of those divisions of the group were impacted by cuts, which were reported earlier by the New York Times.

[...] "In the United States especially, the conversation about climate has been sidetracked by politics," Gates wrote in the introduction to his 2021 book. "Some days, it can seem as if we have little hope of getting anything done." The climate pullback is happening at the same time as the US cuts foreign aid, a field where Gates is also a major donor. His nonprofit, the Gates Foundation, operates with a budget of billions and has a strong focus on overseas development. "Bill Gates remains as committed as ever to advancing the clean energy innovations needed to address climate change," a Breakthrough Energy spokesperson said in an emailed statement. "His work in this area will continue and is focused on helping drive reliable affordable, clean energy solutions that will enable people everywhere to thrive."

On Wednesday, the EPA announced the agency will "undertake 31 historic actions in the greatest and most consequential day of deregulation in U.S. history..."

A new study published in the Journal of Geophysical Research Planets reveals that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. Phys.Org reports: The study applied methods developed to explore Earth's atmosphere to quantitatively estimate the influence of gravity waves on Mars' planetary circulation. [...] "On Earth, large-scale atmospheric waves caused by the planet's rotation, known as Rossby waves, are the primary influence on the way air circulates in the stratosphere, or the lower part of the middle atmosphere. But our study shows that on Mars, gravity waves (GWs) have a dominant effect at the mid and high latitudes of the middle atmosphere," said Professor Kaoru Sato from the Department of Earth and Planetary Science. "Rossby waves are large-scale atmospheric waves, or resolved waves, whereas GWs are unresolved waves, meaning they are too fine to be directly measured or modeled and must be estimated by more indirect means."

Not to be confused with gravitational waves from massive stellar bodies, GWs are an atmospheric phenomenon when a packet of air rises and falls due to variations in buoyancy. That oscillating motion is what gives rise to GWs. Due to the small-scale nature of them and the limitations of observational data, researchers have previously found it challenging to quantify their significance in the Martian atmosphere. So Sato and her team turned to the Ensemble Mars Atmosphere Reanalysis System (EMARS) dataset, produced by a range of space-based observations over many years, to analyze seasonal variations up there.

"We found something interesting, that GWs facilitate the rapid vertical transfer of angular momentum, significantly influencing the meridional, or north-south, in the middle atmosphere circulations on Mars," said graduate student Anzu Asumi. "It's interesting because it more closely resembles the behavior seen in Earth's mesosphere rather than in our stratosphere. This suggests existing Martian atmospheric circulation models may need to be refined to better incorporate these wave effects, potentially improving future climate and weather simulations."

Yale University has suspended a law scholar and pro-Palestinian activist after an AI-generated article from Jewish Onliner falsely linked her to a terrorist group. Gizmodo reports: Helyeh Doutaghi, the scholar at Yale Law School, told the New York Times that she is a "loud and proud" supporter of Palestinian rights. "I am not a member of any organization that would constitute a violation of U.S. law." The article that led to her suspension was published in Jewish Onliner, a Substack that says it is "empowered by A.I. capabilities." The website does not publish the names of its authors out of fear of harassment. Ironically, Doutaghi and Yale were reportedly the subject of intense harassment after Jewish Onliner published the article linking Doutaghi to terrorism by citing appearances she made at events sponsored by Samidoun, a pro-Palestinian group. [...]

Jewish Onliner is vague about how it uses AI to produce its articles, but the technology is known for making lots of mistakes and hallucinating information that is not true. It is quite possible that Jewish Onliner relied on AI to source information it used to write the article. That could open it up to liability if it did not perform fact-checking and due diligence on its writing. Besides the fact that Doutaghi says she is not a member of Samidoun, she attended events it sponsored that support Palestinian causes, Yale Law School said the allegations against her reflect "potential unlawful conduct."

Mozilla is urging Firefox users to update their browsers to version 128 or later (or ESR 115.13 for extended support users) before March 14, 2025, to avoid security risks and add-on disruptions caused by the expiration of a key root certificate. "On 14 March a root certificate (the resource used to prove an add-on was approved by Mozilla) will expire, meaning Firefox users on versions older than 128 (or ESR 115) will not be able to use their add-ons," warns a Mozilla blog post. "We want developers to be aware of this in case some of your users are on older versions of Firefox that may be impacted." BleepingComputer reports: A Mozilla support document explains that failing to update Firefox could expose users to significant security risks and practical issues, which, according to Mozilla, include:

- Malicious add-ons can compromise user data or privacy by bypassing security protections.
- Untrusted certificates may allow users to visit fraudulent or insecure websites without warning.
- Compromised password alerts may stop working, leaving users unaware of potential account breaches.

It is noted that the problem impacts Firefox on all platforms, including Windows, Android, Linux, and macOS, except for iOS, where there's an independent root certificate management system. Mozilla says that users relying on older versions of Firefox may continue using their browsers after the expiration of the certificate if they accept the security risks, but the software's performance and functionality may be severely impacted.

Ancient Slashdot reader Alain Williams shares a report from the BBC: Meta has won an emergency ruling in the US to temporarily stop a former director of Facebook from promoting or further distributing copies of her memoir. The book, Careless People by Sarah Wynn-Williams, who used to be the company's global public policy director, includes a series of critical claims about what she witnessed during her seven years working at Facebook.

Facebook's parent company, Meta, says the ruling -- which orders her to stop promotions "to the extent within her control" -- affirms that "the false and defamatory book should never have been published." The UK publisher Macmillan says it is "committed to upholding freedom of speech" and Ms Wynn-Williams' "right to tell her story." [You can also hear Ms Wynn-Williams interviewed in the BBC Radio 4 Media Show on March 12.]

An anonymous reader shares a report: Germany's foreign intelligence service in 2020 put at 80%-90% the likelihood that the coronavirus behind the COVID-19 pandemic was accidentally released from China's Wuhan Institute of Virology, two German newspapers reported on Wednesday.

According to a joint report by publications Die Zeit and Sueddeutscher Zeitung, Germany's spying agency BND had indications that the institute had conducted gain-of-function experiments, whereby viruses are modified to become more transmissible to humans for research purposes.

It also had indications that numerous violations of safety regulations had occurred at the lab, the papers said. The spy agency assessment's was based on an unspecified intelligence operation code-named "Saaremaa" as well as on publicly-available data. It had been commissioned by the office of Germany's chancellor at the time, Angela Merkel, but never published, the report said.

Mozilla has warned that the U.S. Department of Justice's proposed remedies in its antitrust case against Google would harm independent browsers and reduce competition in the browser market. The DOJ and several state attorneys general last week filed revised proposed remedies in the U.S. v. Google search case that would prohibit all search payments to browser developers, a move Mozilla says would disproportionately impact smaller players.

"These proposed remedies prohibiting search payments to small and independent browsers miss the bigger picture -- and the people who will suffer most are everyday internet users," said Mark Surman, President of Mozilla. Unlike Apple and Microsoft, which generate revenue from hardware and operating systems, Mozilla relies primarily on search revenue to fund browser development. Mozilla argues that cutting these payments would not solve search dominance but would instead strengthen the position of tech giants.

Mozilla also warned that the proposal threatens its ability to maintain Gecko, one of only three major browser engines alongside Google's Chromium and Apple's WebKit. "If we lose our ability to maintain Gecko, it's game over for an open, independent web," Surman said, noting that even Microsoft abandoned its browser engine in 2019. "If Mozilla is unable to sustain our browser engine, it would severely impact browser engine competition and mean the death of the open web as we know it -- essentially, creating a web where dominant players like Google and Apple, have even more control, not less."

Firefox serves 27 million monthly active users in the U.S. and nearly 205 million globally.

Britain's competition watchdog has concluded that Apple and Google are stifling competition in the UK mobile browser market, following an investigation by the Competition and Markets Authority (CMA). The inquiry found Apple's iOS policies particularly restrictive, requiring all browsers to use its WebKit engine while giving Safari preferential access to features.

Apple's practice of pre-installing Safari as the default browser also reduces awareness of alternatives, despite allowing users to change defaults. Google faces similar criticism for pre-installing Chrome on most Android devices, though investigators noted both companies have recently taken steps to facilitate browser switching. The probe identified Apple's revenue-sharing arrangement with Google -- which pays a significant share of search revenue to be the default iPhone search engine -- as "significantly reducing their financial incentives to compete."

Google says its new open-source AI model, Gemma 3, achieves nearly the same performance as DeepSeek AI's R1 while using just one Nvidia H100 GPU, compared to an estimated 32 for R1. ZDNet reports: Using "Elo" scores, a common measurement system used to rank chess and athletes, Google claims Gemma 3 comes within 98% of the score of DeepSeek's R1, 1338 versus 1363 for R1. That means R1 is superior to Gemma 3. However, based on Google's estimate, the search giant claims that it would take 32 of Nvidia's mainstream "H100" GPU chips to achieve R1's score, whereas Gemma 3 uses only one H100 GPU.

Google's balance of compute and Elo score is a "sweet spot," the company claims. In a blog post, Google bills the new program as "the most capable model you can run on a single GPU or TPU," referring to the company's custom AI chip, the "tensor processing unit." "Gemma 3 delivers state-of-the-art performance for its size, outperforming Llama-405B, DeepSeek-V3, and o3-mini in preliminary human preference evaluations on LMArena's leaderboard," the blog post relates, referring to the Elo scores. "This helps you to create engaging user experiences that can fit on a single GPU or TPU host."

Google's model also tops Meta's Llama 3's Elo score, which it estimates would require 16 GPUs. (Note that the numbers of H100 chips used by the competition are Google's estimate; DeepSeek AI has only disclosed an example of using 1,814 of Nvidia's less-powerful H800 GPUs to server answers with R1.) More detailed information is provided in a developer blog post on HuggingFace, where the Gemma 3 repository is offered.

According to The Verge, Sonos has abandoned its plans to release a streaming video player this year. From the report: The news was announced by the company's leadership during an all-hands call today. That product, codenamed Pinewood, was set to be Sonos' next major hardware launch. It was already deep into development and has spent months in beta testing. But now the team behind it will be reassigned to other projects as interim CEO Tom Conrad reprioritizes the company's future roadmap and continues what he hopes will be a turnaround from a bruising 2024. He told employees that a push into video from Sonos is off the table "for now." [...]

Pinewood was designed to offer many of the same streaming video apps as other devices on the market along with deep universal search and content aggregation. But as I reported last month, Sonos also intended for it to double as an HDMI switcher and support passthrough functionality for gaming consoles, 4K Blu-ray players, and more. The box was also set to allow new configurations of surround sound systems using Sonos' many speakers.

An anonymous reader quotes a report from the EFF: EFF is deeply saddened to learn of the passing of Mark Klein, a bona fide hero who risked civil liability and criminal prosecution to help expose a massive spying program that violated the rights of millions of Americans. Mark didn't set out to change the world. For 22 years, he was a telecommunications technician for AT&T, most of that in San Francisco. But he always had a strong sense of right and wrong and a commitment to privacy. When the New York Times reported in late 2005 that the NSA was engaging in spying inside the U.S., Mark realized that he had witnessed how it was happening. He also realized that the President was not telling Americans the truth about the program. And, though newly retired, he knew that he had to do something. He showed up at EFF's front door in early 2006 with a simple question: "Do you folks care about privacy?"

We did. And what Mark told us changed everything. Through his work, Mark had learned that the National Security Agency (NSA) had installed a secret, secure room at AT&T's central office in San Francisco, called Room 641A. Mark was assigned to connect circuits carrying Internet data to optical "splitters" that sat just outside of the secret NSA room but were hardwired into it. Those splitters -- as well as similar ones in cities around the U.S. -- made a copy of all data going through those circuits and delivered it into the secret room. Mark not only saw how it works, he had the documents to prove it. He brought us over a hundred pages of authenticated AT&T schematic diagrams and tables. Mark also shared this information with major media outlets, numerous Congressional staffers, and at least two senators personally. One, Senator Chris Dodd, took the floor of the Senate to acknowledge Mark as the great American hero he was.

Schools across the United States are increasingly using artificial intelligence to monitor students' online activities, raising significant privacy concerns after Vancouver Public Schools inadvertently released nearly 3,500 unredacted, sensitive student documents to reporters.

The surveillance software, developed by companies like Gaggle Safety Management, scans school-issued devices 24/7 for signs of bullying, self-harm, or violence, alerting staff when potential issues are detected. Approximately 1,500 school districts nationwide use Gaggle's technology to track six million students, with Vancouver schools paying $328,036 for three years of service.

While school officials maintain the technology has helped counselors intervene with at-risk students, documents revealed LGBTQ+ students were potentially outed to administrators through the monitoring.

AmiMoJo shares a report from Electrek: The U.S. installed 50 gigawatts (GW) of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades. That's enough to power 8.5 million households. According to the U.S. Solar Market Insight 2024 Year in Review report (PDF) released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, solar and storage account for 84% of all new electric generating capacity added to the grid last year.

In addition to historic deployment, surging U.S. solar manufacturing emerged as a landmark economic story in 2024. Domestic solar module production tripled last year, and at full capacity, U.S. factories can now produce enough to meet nearly all demand for solar panels in the U.S. Solar cell manufacturing also resumed in 2024, strengthening the U.S. energy supply chain. [...] Total US solar capacity is expected to reach 739 GW by 2035, but the report forecasts include scenarios showing how policy changes could impact the solar market. [...] The low case forecast shows a 130 GW decline in solar deployment over the next decade compared to the base case, representing nearly $250 billion of lost investment.

An anonymous reader quotes a report from TechCrunch: There's a power crunch looming as AI and cloud providers ramp up data center construction. But a new report suggests that a solution lies beneath their foundations. Advanced geothermal power could supply nearly two-thirds of new data center demand by 2030, according to an analysis by the Rhodium Group. The additions would quadruple the amount of geothermal power capacity in the U.S. -- from 4 gigawatts to about 16 gigawatts -- while costing the same or less than what data center operators pay today. In the western U.S., where geothermal resources are more plentiful, the technology could provide 100% of new data center demand. Phoenix, for example, could add 3.8 gigawatts of data center capacity without building a single new conventional power plant.

Geothermal resources have enormous potential to provide consistent power. Historically, geothermal power plants have been limited to places where Earth's heat seeps close to the surface. But advanced geothermal techniques could unlock 90 gigawatts of clean power in the U.S. alone, according to the U.S. Department of Energy. [...] Because geothermal power has very low running costs, its price is competitive with data centers' energy costs today, the Rhodium report said. When data centers are sited similarly to how they are today, a process that typically takes into account proximity to fiber optics and major metro areas, geothermal power costs just over $75 per megawatt hour. But when developers account for geothermal potential in their siting, the costs drop significantly, down to around $50 per megawatt hour.

The report assumes that new generating capacity would be "behind the meter," which is what experts call power plants that are hooked up directly to a customer, bypassing the grid. Wait times for new power plants to connect to the grid can stretch on for years. As a result, behind the meter arrangements have become more appealing for data center operators who are scrambling to build new capacity.

Spain's government has approved legislation imposing substantial fines of up to 35 million euros or 7% of global turnover on companies that fail to clearly label AI-generated content. Reuters reports: The bill adopts guidelines from the European Union's landmark AI Act imposing strict transparency obligations on AI systems deemed to be high-risk, Digital Transformation Minister Oscar Lopez told reporters. "AI is a very powerful tool that can be used to improve our lives ... or to spread misinformation and attack democracy," he said. Spain is among the first EU countries to implement the bloc's rules, considered more comprehensive than the United States' system that largely relies on voluntary compliance and a patchwork of state regulations. Lopez added that everyone was susceptible to "deepfake" attacks - a term for videos, photographs or audios that have been edited or generated through AI algorithms but are presented as real. [...]

The bill also bans other practices, such as the use of subliminal techniques - sounds and images that are imperceptible - to manipulate vulnerable groups. Lopez cited chatbots inciting people with addictions to gamble or toys encouraging children to perform dangerous challenges as examples. It would also prevent organizations from classifying people through their biometric data using AI, rating them based on their behavior or personal traits to grant them access to benefits or assess their risk of committing a crime. However, authorities would still be allowed to use real-time biometric surveillance in public spaces for national security reasons.

Southwest Airlines boasts that its passengers' "bags fly free" -- but not for long. From a report: Starting May 28 -- just in time for the busy summer travel season -- only Southwest's most elite Rapid Rewards A-List Preferred members and passengers who book their top-tier Business Select fares will receive two free checked bags. Frequent flyer A-List Members, Southwest-branded credit card holders and other select customers will be allowed one checked bag.

Everyone else will be charged for their first and second checked bags on flights booked on or after May 28, the carrier says. It's a break with Southwest's 54 year history -- one that could undermine customer loyalty to the carrier, according to experts. "This is how you destroy a brand. This is how you destroy customer preference. This is how you destroy loyalty. And this, I think, is going to send Southwest into a financial tailspin," airline industry analyst Henry Harteveldt, of Atmosphere Research Group, told CBS News senior transportation correspondent Kris Van Cleave. "Southwest, with these changes, becomes just another airline."

Nearly every country on Earth has dirtier air than doctors recommend breathing, a report has found. From a report: Only seven countries met the World Health Organization's guidelines for tiny toxic particles known as PM2.5 last year, according to analysis from the Swiss air quality technology company IQAir. Australia, New Zealand and Estonia were among the handful of countries with a yearly average of no more than 5ug of PM2.5 per cubic metre, along with Iceland and some small island states.

The most polluted countries were Chad, Bangladesh, Pakistan, the Democratic Republic of the Congo and India. PM2.5 levels in all five countries were at least 10 times higher than guideline limits in 2024, the report found, stretching as much as 18 times higher than recommended levels in Chad. Doctors say there are no safe levels of PM2.5, which is small enough to slip into the bloodstream and damage organs throughout the body, but have estimated millions of lives could be saved each year by following their guidelines. Dirty air is the second-biggest risk factor for dying after high blood pressure.
