According to the Solar Energy Industries Association (SEIA), the U.S. has officially surpassed 5 million solar installations. "The 5 million milestone comes just eight years after the U.S. achieved its first million in 2016 -- a stark contrast to the four decades it took to reach that initial milestone since the first grid-connected solar project in 1973," reports Electrek. From the report: Since the beginning of 2020, more than half of all U.S. solar installations have come online, and over 25% have been activated since the Inflation Reduction Act became law 20 months ago. Solar arrays have been installed on homes and businesses and as utility-scale solar farms. The U.S. solar market was valued at $51 billion in 2023. Even with changes in state policies, market trends indicate robust growth in solar installations across the U.S. According to SEIA forecasts, the number of solar installations is expected to double to 10 million by 2030 and triple to 15 million by 2034.

The residential sector represents 97% of all U.S. solar installations. This sector has consistently set new records for annual installations over the past several years, achieving new highs for five straight years and in 10 out of the last 12 years. The significant growth in residential solar can be attributed to its proven value as an investment for homeowners who wish to manage their energy costs more effectively. California is the frontrunner with 2 million solar installations, though recent state policies have significantly damaged its rooftop solar market. Meanwhile, other states are experiencing rapid growth. For example, Illinois, which had only 2,500 solar installations in 2017, now boasts over 87,000. Similarly, Florida has seen its solar installations surge from 22,000 in 2017 to 235,000 today. By 2030, 22 states or territories are anticipated to surpass 100,000 solar installations. The U.S. has enough solar installed to cover every residential rooftop in the Four Corners states of Colorado, Utah, Arizona, and New Mexico.

Kylie Robison reports via The Verge: Hugging Face, one of the biggest names in machine learning, is committing $10 million in free shared GPUs to help developers create new AI technologies. The goal is to help small developers, academics, and startups counter the centralization of AI advancements. [...] Delangue is concerned about AI startups' ability to compete with the tech giants. Most significant advancements in artificial intelligence -- like GPT-4, the algorithms behind Google Search, and Tesla's Full Self-Driving system -- remain hidden within the confines of major tech companies. Not only are these corporations financially incentivized to keep their models proprietary, but with billions of dollars at their disposal for computational resources, they can compound those gains and race ahead of competitors, making it impossible for startups to keep up. Hugging Face aims to make state-of-the-art AI technologies accessible to everyone, not just the tech giants. [...]

Access to compute poses a significant challenge to constructing large language models, often favoring companies like OpenAI and Anthropic, which secure deals with cloud providers for substantial computing resources. Hugging Face aims to level the playing field by donating these shared GPUs to the community through a new program called ZeroGPU. The shared GPUs are accessible to multiple users or applications concurrently, eliminating the need for each user or application to have a dedicated GPU. ZeroGPU will be available via Hugging Face's Spaces, a hosting platform for publishing apps, which has over 300,000 AI demos created so far on CPU or paid GPU, according to the company.

Access to the shared GPUs is determined by usage, so if a portion of the GPU capacity is not actively utilized, that capacity becomes available for use by someone else. This makes them cost-effective, energy-efficient, and ideal for community-wide utilization. ZeroGPU uses Nvidia A100 GPU devices to power this operation -- which offer about half the computation speed of the popular and more expensive H100s. "It's very difficult to get enough GPUs from the main cloud providers, and the way to get them -- which is creating a high barrier to entry -- is to commit on very big numbers for long periods of times," Delangue said. Typically, a company would commit to a cloud provider like Amazon Web Services for one or more years to secure GPU resources. This arrangement disadvantages small companies, indie developers, and academics who build on a small scale and can't predict if their projects will gain traction. Regardless of usage, they still have to pay for the GPUs. "It's also a prediction nightmare to know how many GPUs and what kind of budget you need," Delangue said.

Longtime Slashdot reader necro81 writes: The U.S. Federal Energy Regulatory Commission (FERC), which controls interstate energy infrastructure, approved a rule Monday that should boost new transmission infrastructure and make it easier to connect renewable energy projects. (More coverage here, here, and here.)

Some 11,000 projects totaling 2,600 GW of capacity are in planning, waiting to break ground, or connect to the grid. But they're stymied by the need for costly upgrades, or simply waiting for review. The frustrations are many. Each proposed project undergoes a lengthy grid-impact study and assessed the cost of necessary upgrades. Each project is considered in isolation, regardless of whether similar projects are happening nearby that could share the upgrade costs or auger different improvements. The planning process tends to be reactive -- examining only the applications in front of them -- rather than considering trends over the coming years. It's a first-come, first-served queue: if one project is ready to break ground, it must wait behind another project that's still securing funding or permitting.

Two years in development, the dryly-named Improvements to Generator Interconnection Procedures and Agreements directs utility operators to plan infrastructure improvements with a 20-yr forecast of new energy sources and increased demand. Rather than examining each project in isolation, similar projects will be clustered and examined together. Instead of a First-Come, First-Served serial process, operators will instead examine First-Ready, allowing shovel-ready projects to jump the queue. The expectation is that these new rules will speed up and streamline the process of developing and connecting new energy projects through more holistic planning, penalties for delays, sensible cost-sharing for upgrades, and justification for long-term investments.

Researchers believe they've discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging. The new find needs optimization but has the potential to help power electric vehicles. * An anonymous reader shared this report from Popular Mechanics: In a study published in Science, lead author Sang-Hoon Bae, an assistant professor of mechanical engineering and materials science, demonstrates a novel heterostructure that curbs energy loss, enabling capacitors to store more energy and charge rapidly without sacrificing durability... Within capacitors, ferroelectric materials offer high maximum polarization. That's useful for ultra-fast charging and discharging, but it can limit the effectiveness of energy storage or the "relaxation time" of a conductor. "This precise control over relaxation time holds promise for a wide array of applications and has the potential to accelerate the development of highly efficient energy storage systems," the study authors write.

Bae makes the change — one he unearthed while working on something completely different — by sandwiching 2D and 3D materials in atomically thin layers, using chemical and nonchemical bonds between each layer. He says a thin 3D core inserts between two outer 2D layers to produce a stack that's only 30 nanometers thick, about 1/10th that of an average virus particle... The sandwich structure isn't quite fully conductive or nonconductive.

This semiconducting material, then, allows the energy storage, with a density up to 19 times higher than commercially available ferroelectric capacitors, while still achieving 90 percent efficiency — also better than what's currently available.

An anonymous reader shared this report from the Register: The co-author of SQL, the standardized query language for relational databases, has come out in support of the NoSQL database movement that seeks to escape the tabular confines of the RDBMS. Speaking to The Register as SQL marks its 50th birthday, Donald Chamberlin, who first proposed the language with IBM colleague Raymond Boyce in a 1974 paper [PDF], explains that NoSQL databases and their query languages could help perform the tasks relational systems were never designed for. "The world doesn't stay the same thing, especially in computer science," he says. "It's a very fast, evolving, industry. New requirements are coming along and technology has to change to meet them, I think that's what's happening. The NoSQL movement is motivated by new kinds of applications, particularly web applications, that need massive scalability and high performance. Relational databases were developed in an earlier generation when scalability and performance weren't quite as important. To get the scalability and performance that you need for modern apps, many systems are relaxing some of the constraints of the relational data model."

[...] A long-time IBMer, Chamberlin is now semi-retired, but finds time to fulfill a role as a technical advisor for NoSQL company Couchbase. In the role, he has become an advocate for a new query language designed to overcome the "impedance mismatch" between data structures in the application language and a database, he says. UC San Diego professor Yannis Papakonstantinou has proposed SQL++ to solve this problem, with a view to addressing impedance mismatch between heavily object-based JavaScript, the core language for web development and the assumed relational approach embedded in SQL. Like C++, SQL++ is designed as a compatible extension of an earlier language, SQL, but is touted as better able to handle the JSON file format inherent in JavaScript. Couchbase and AWS have adopted the language, although the cloud giant calls it PartiQL.
At the end of the interview, Chamblin adds that "I don't think SQL is going to go away. A large part of the world's business data is encoded in SQL, and data is very sticky. Once you've got your database, you're going to leave it there. Also, relational systems do a very good job of what they were designed to do...

"[I]f you're a startup company that wants to sell shoes on the web or something, you're going to need a database, and one of those SQL implementations will do the job for free. I think relational databases and the SQL language will be with us for a long time."

The Royal Institution of Australia is a national non-profit hub for science communication, publishing the science magazine Cosmos four times a year.

This month they argued that small modular nuclear reactors "don't add up as a viable energy source." Proponents assert that SMRs would cost less to build and thus be more affordable. However, when evaluated on the basis of cost per unit of power capacity, SMRs will actually be more expensive than large reactors. This 'diseconomy of scale' was demonstrated by the now-terminated proposal to build six NuScale Power SMRs (77 megawatts each) in Idaho in the United States. The final cost estimate of the project per megawatt was around 250 percent more than the initial per megawatt cost for the 2,200 megawatts Vogtle nuclear power plant being built in Georgia, US. Previous small reactors built in various parts of America also shut down because they were uneconomical.
The cost was four to six times the cost of the same electricity from wind and solar photovoltaic plants, according to estimates from the Australian Commonwealth Scientific and Industrial Research Organisation and the Australian Energy Market Operator. "The money invested in nuclear energy would save far more carbon dioxide if it were instead invested in renewables," the article agues: Small reactors also raise all of the usual concerns associated with nuclear power, including the risk of severe accidents, the linkage to nuclear weapons proliferation, and the production of radioactive waste that has no demonstrated solution because of technical and social challenges. One 2022 study calculated that various radioactive waste streams from SMRs would be larger than the corresponding waste streams from existing light water reactors...

Nuclear energy itself has been declining in importance as a source of power: the fraction of the world's electricity supplied by nuclear reactors has declined from a maximum of 17.5 percent in 1996 down to 9.2 percent in 2022. All indications suggest that the trend will continue if not accelerate. The decline in the global share of nuclear power is driven by poor economics: generating power with nuclear reactors is costly compared to other low-carbon, renewable sources of energy and the difference between these costs is widening.

Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology.
From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten.

"I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks.

And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis."

This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading.
The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

A tokamak in France achieved a new record in fusion plasma by using tungsten to encase its reaction, which enabled the sustainment of hotter and denser plasma for longer periods than previous carbon-based designs. Quartz reports: A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA). WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak's interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible.

"These are beautiful results," said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. "We have reached a stationary regime despite being in a challenging environment due to this tungsten wall."

A "one-of-a-kind" Google Cloud "misconfiguration" resulted in the deletion of UniSuper's account last week, disrupting the financial services provider's more than half a million members. "Services began being restored for UniSuper customers on Thursday, more than a week after the system went offline," reports The Guardian. "Investment account balances would reflect last week's figures and UniSuper said those would be updated as quickly as possible." From the report: The UniSuper CEO, Peter Chun, wrote to the fund's 620,000 members on Wednesday night, explaining the outage was not the result of a cyber-attack, and no personal data had been exposed as a result of the outage. Chun pinpointed Google's cloud service as the issue. In an extraordinary joint statement from Chun and the global CEO for Google Cloud, Thomas Kurian, the pair apologized to members for the outage, and said it had been "extremely frustrating and disappointing." They said the outage was caused by a misconfiguration that resulted in UniSuper's cloud account being deleted, something that had never happened to Google Cloud before.

While UniSuper normally has duplication in place in two geographies, to ensure that if one service goes down or is lost then it can be easily restored, because the fund's cloud subscription was deleted, it caused the deletion across both geographies. UniSuper was able to eventually restore services because the fund had backups in place with another provider. "Google Cloud CEO, Thomas Kurian has confirmed that the disruption arose from an unprecedented sequence of events whereby an inadvertent misconfiguration during provisioning of UniSuper's Private Cloud services ultimately resulted in the deletion of UniSuper's Private Cloud subscription," the pair said. "This is an isolated, 'one-of-a-kind occurrence' that has never before occurred with any of Google Cloud's clients globally. This should not have happened. Google Cloud has identified the events that led to this disruption and taken measures to ensure this does not happen again."

ArchieBunker quotes a report from Bloomberg: Texas electricity prices soared almost 100-fold as a high number of power-plant outages raised concerns of a potential evening shortfall. Spot prices at the North Hub, which includes Dallas, jumped to more than $3,000 a megawatt-hour just before 7 p.m. local time, versus about $32 at the same time Tuesday, according to data from the Electric Reliability Council of Texas. This morning, Ercot, as the state's main grid operator is known, issued a "watch" for a potential capacity reserve shortage from about 7-9 p.m., meaning the buffer of spare supplies could fall to low enough levels to call on back-up generation, cancel or delay outages or curb usage.

The conditions are the tightest of the year so far and raises the risk of prices rising to the $5,000 cap -- which they last did on April 16, when Ercot also warned of a potential shortfall. Unusually hot weather in the region has boosted demand for cooling and lowered the efficiency of many power plants. Wind output has also fallen from a day earlier and there are more outages. "Ercot has not called for conservation this evening," it said by email. "The grid is operating under normal conditions at this time."

Citing a memo distributed to Apple Store employees, 9to5Mac reports that the new iPad Pro and iPad Air lineups will not include Apple stickers in the box -- "a key piece of memorabilia" that dates back as far as 1977's Apple II, notes Ars Technica. While the company says that this is part of its environmental goals to completely remove plastic from its packaging, it begs the question: is the era of stickers in Apple boxes coming to an end? 9to5Mac reports: The M3 MacBook Air that launched in March includes stickers in the box, but Apple Vision Pro (which launched in February) does not. Will the iPhone 16 include stickers in the box? Only time will tell. Ars' Andrew Cunningham writes about the origins of the Apple stickers: Apple has included stickers with its products at least as far back as the Apple II in 1977 when the stickers still said "Apple Computer" on them in the company's then-favored Motter Tektura typeface (I couldn't track down a vintage Apple II unboxing, but I did find some fun photos of Apple enthusiast Dan Budiac opening a sealed-in-box mid-'80s-era Apple IIc, complete with rainbow pack-in stickers). I myself became familiar with them during the height of the iPod in the early to mid-2000s when Apple was still firmly a tech underdog, and people would stick white Apple logo stickers to their cars to show off their non-conformist cred and/or Apple brand loyalty.

As Apple's products became more colorful in the 2010s, the Apple logo stickers would sometimes be color-matched to the device you had just bought, a cute bit of attention to detail that has carried over into present-day MagSafe cables and color-matched iMac keyboards and trackpads. The report notes that you can still request an Apple sticker at Apple Stores at the time of your purchase; however, Amazon, Best Buy, and other retailers don't appear to have them available.

Renewable energy accounted for more than 30% of the world's electricity for the first time last year, according to climate thinktank Ember. The Guardian reports: Clean electricity has already helped to slow the growth in fossil fuels by almost two-thirds in the past 10 years, according to the report by climate thinktank Ember. It found that renewables have grown from 19% of electricity in 2000 to more than 30% of global electricity last year. Solar was the main supplier of electricity growth, according to Ember, adding more than twice as much new electricity generation as coal in 2023. It was the fastest-growing source of electricity for the 19th consecutive year, and also became the largest source of new electricity for the second year running, after surpassing wind power.

The first comprehensive review of global electricity data covers 80 countries, which represent 92% of the world's electricity demand, as well as historic data for 215 countries. The surge in clean electricity is expected to power a 2% decrease in global fossil fuel generation in the year ahead, according to Ember. [...] World leaders are aiming to grow renewables to 60% of global electricity by 2030 under an agreement struck at the UN's Cop28 climate change conference in December. This would require countries to triple their current renewable electricity capacity in the next six years, which would almost halve power sector emissions.

An anonymous reader quotes a report from Ars Technica: In a major shake-up of its chip roadmap, Apple has announced a new M4 processor for today's iPad Pro refresh, barely six months after releasing the first MacBook Pros with the M3 and not even two months after updating the MacBook Air with the M3. Apple says the M4 includes "up to" four high-performance CPU cores, six high-efficiency cores, and a 10-core GPU. Apple's high-level performance estimates say that the M4 has 50 percent faster CPU performance and four times as much graphics performance. Like the GPU in the M3, the M4 also supports hardware-accelerated ray-tracing to enable more advanced lighting effects in games and other apps. Due partly to its "second-generation" 3 nm manufacturing process, Apple says the M4 can match the performance of the M2 while using just half the power.

As with so much else in the tech industry right now, the M4 also has an AI focus; Apple says it's beefing up the 16-core Neural Engine (Apple's equivalent of the Neural Processing Unit that companies like Qualcomm, Intel, AMD, and Microsoft have been pushing lately). Apple says the M4 runs up to 38 trillion operations per second (TOPS), considerably ahead of Intel's Meteor Lake platform, though a bit short of the 45 TOPS that Qualcomm is promising with the Snapdragon X Elite and Plus series. The M3's Neural Engine is only capable of 18 TOPS, so that's a major step up for Apple's hardware. Apple's chips since 2017 have included some version of the Neural Engine, though to date, those have mostly been used to enhance and categorize photos, perform optical character recognition, enable offline dictation, and do other oddities. But it may be that Apple needs something faster for the kinds of on-device large language model-backed generative AI that it's expected to introduce in iOS and iPadOS 18 at WWDC next month. A separate report from the Wall Street Journal says Apple is developing a custom chip to run AI software in datacenters. "Apple's server chip will likely be focused on running AI models, also known as inference, rather than in training AI models, where Nvidia is dominant," reports Reuters.

The Register provides a retrospective look at how Microsoft "absorbed the handset division of Nokia" ten years ago, only to kill the unit two years later and write it off as a tax loss. What went wrong? "It was a fatal combination of bad management, a market evolving in ways hidebound people didn't predict, and some really (with a few superb exceptions) terrible products," reports The Register. From the report: Like Nokia, Windows Mobile's popularity peaked in 2007, then started to drop away. The iPhone was the tech item of choice for fashionistas, Blackberry was seen as essential for serious business, and Android -- with Google as its new owner -- was gaining traction. Microsoft by that time had a new CEO in Steve Ballmer, who completely and famously failed to see the shifting sands in the mobile market. He dismissed the iPhone as a threat to what he thought was Windows Mobile's unassailable market position, and was roundly mocked for it. So the scene was set for a mobile standards war, and Steve Ballmer staked his professional pride on winning it. Microsoft recruited Nokia to help out. [...]

Under [Executive VP of Microsoft Stephen Elop's] leadership, a closer working relationship with Microsoft was a given -- but in 2013 Redmond announced it was going the whole hog and buying Nokia's handset business outright for $7.2 billion. The deal was done in April 2014, a decade ago from today. Microsoft also got a ten-year license on Nokia's patents and the option to renew in perpetuity. It also got Elop back, as executive vice president of the Microsoft Devices Group. That meant stepping down as CEO of Nokia, for which he trousered an 18.8 million bonus package -- a payoff the Finnish prime minister at the time called "outrageous." Nokia retained its networking business in Finland. It purchased Siemens' half of the Nokia Siemens Networks joint venture and renamed in Nokia Networks. The Nokia board rolled the dice again on hiring another non-Suomi manager, Rajeev Suri, and this time hit a double D20 in D&D terms.

When Ballmer stepped down from the helm at Microsoft in 2014 -- shortly before the Nokia deal completion -- he left a hot mess to deal with. His plan had been to develop the mobile operating system in conjunction with Windows 10, and Windows Mobile 10 was supposed to be a part of a unified code environment. While Windows 10 on the desktop wasn't a bad operating system, Windows Mobile 10 really was. The promised synergy just didn't happen -- it was power-hungry, clunky, and about as popular as a rattlesnake in a pinata. It was this mess that Satya Nadella faced when he took over the reins. Nadella was never very keen on the phone platform and spent more time in press conferences talking about cricket or the cloud than Microsoft's mobile ambitions. It was clear to all that this really wasn't working. Elop was laid off by Redmond a year later.

It was clear that Windows Mobile wasn't going to work. Android and iOS were drinking Microsoft's milkshake, and Redmond realized the game was up. Microsoft started shedding mobile jobs -- both in Finland and Redmond. While mobile was still publicly touted as the way forward for Microsoft with Ballmer gone, the impetus wasn't there and support for the mobile OS shriveled. In 2015 Microsoft declared it was writing off $7.6 billion on the Phone Hardware division as "goodwill and asset impairment charges" -- $400 million more than it had originally paid for the Finnish firm. Nokia bought European networking giant Alcatel-Lucent in a $16.7 billion deal in 2015. Around the same time, Suri announced a move into tablets, since it had a non-compete agreement with Microsoft on mobiles. Meanwhile a bunch of former Nokia execs who'd fled Elop and Microsoft had started a mobile biz of their own: HMD. It was Finnish, but outsourced production to Foxconn in China, and was planning to make cheapish Android devices. In 2016 Microsoft sold its mobile hardware arm to HMD for an undisclosed -- but probably not large -- sum. Nadella clearly wanted out of the whole business and the Finnish startup concentrated on selling good-enough Android smartphones to Nokia's traditional cheap markets.

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.

The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator.

Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.
