New research by two leading scientists says some dire warnings of environmental damage from technology are overstated. From a report: The giant tech companies with their power-hungry, football-field-size data centers are not the environmental villains they are sometimes portrayed to be on social media and elsewhere. Shutting off your Zoom camera or throttling your Netflix service to lower-definition viewing does not yield a big saving in energy use, contrary to what some people have claimed. Even the predicted environmental impact of Bitcoin, which does require lots of computing firepower, has been considerably exaggerated by some researchers.

Those are the conclusions of a new analysis by Jonathan Koomey and Eric Masanet, two leading scientists in the field of technology, energy use and the environment. Both are former researchers at the Lawrence Berkeley National Laboratory. Mr. Koomey is now an independent analyst, and Mr. Masanet is a professor at the University of California, Santa Barbara. (Mr. Masanet receives research funding from Amazon.) They said their analysis, published earlier this month as a commentary article in Joule, a scientific journal, was not necessarily intended to be reassuring. Instead, they said, it is meant to inject a dose of reality into the public discussion of technology's impact on the environment. The surge in digital activity spurred by the Covid-19 pandemic, the scientists said, has fueled the debate and prompted dire warnings of environmental damage. They are concerned that wayward claims, often amplified by social media, could shape behavior and policy.

Westland Real Estate Group patrols its 1,000-unit apartment complex in Las Vegas with "a conical, bulky, artificial intelligence-powered robot" standing just over 5 feet tall, according to NBC News. Manufactured by Knightscope, the robot is equipped with four internal cameras capturing a constant 360-degree view, and can also scan and record license plates (as well as the MAC addresses of cellphones). But is it doing any good? As more government agencies and private sector companies resort to robots to help fight crime, the verdict is out about how effective they are in actually reducing it. Knightscope, which experts say is the dominant player in this market, has cited little public evidence that its robots have reduced crime as the company deploys them everywhere from a Georgia shopping mall to an Arizona development to a Nevada casino. Knightscope's clients also don't know how much these security robots help. "Are we seeing dramatic changes since we deployed the robot in January?" Dena Lerner, the Westland spokesperson said. "No. But I do believe it is a great tool to keep a community as large as this, to keep it safer, to keep it controlled."

For its part, Knightscope maintains on its website that the robots "predict and prevent crime," without much evidence that they do so. Experts say this is a bold claim. "It would be difficult to introduce a single thing and it causes crime to go down," said Ryan Calo, a law professor at the University of Washington, comparing the Knightscope robots to a "roving scarecrow." Additionally, the company does not provide specific, detailed examples of crimes that have been thwarted due to the robots.
The robots are expensive — they're rented out at about $70,000-$80,000 a year — but growth has stalled for the two years since 2018, and over four years Knightscope's total clients actually dropped from 30 to just 23. (Expenses have now risen — partly because the company is now doubling its marketing budget.)

There's also a thermal scanning feature, but Andrew Ferguson, a law professor at American University, still called these robots an "expensive version of security theater." And NBC News adds that KnightScope's been involved "in both tragic and comical episodes." In 2016, a K5 roaming around Stanford Shopping Center in Palo Alto, California, hit a 16-month-old toddler, bruising his leg and running over his foot. The company apologized, calling it a "freakish accident," and invited the family to visit the company's nearby headquarters in Mountain View, which the family declined. The following year, another K5 robot slipped on steps adjacent to a fountain at the Washington Harbour development in Washington, D.C., falling into the water. In October 2019, a Huntington Park woman, Cogo Guebara, told NBC News that she tried reporting a fistfight by pressing an emergency alert button on the HP RoboCop itself, but to no avail. She learned later the emergency button was not yet connected to the police department itself... [The northern California city] Hayward dispatched its robot in a city parking garage in 2018. The following year, a man attacked and knocked over the robot. Despite having clear video and photographic evidence of the alleged crime, no one was arrested, according to Adam Kostrzak, the city's chief information officer.
The city didn't renew its contract "due to the financial impact of Covid-19 in early 2020," the city's CIO tells NBC News. But the city had already spent over $137,000 on the robot over two years.

Some users who bought an external hard drive that's delightfully shaped like a book ended up with "terabytes' worth of data, years of memories and months of hard work vanished in an instant," reports Engadget. (Though according to a new statement from Western Digital, "Some customers have reported that data recovery tools may be able to recover data from affected devices, and we are currently investigating the effectiveness of these tools.")

But why were these deletions from "My Books" happening in the first place? A Slashdot reader shares the first clue from Engadget's report: Several owners looked into the cause of the issue and determined that their devices were wiped after receiving a remote command for a factory reset. The commands starting going out at 3PM on Wednesday and lasted throughout the night. One user posted a copy of their log showing how a script was run to shut down their storage device for a factory restore.
Friday Western Digital's statement offered much more detail: Western Digital has determined that some My Book Live and My Book Live Duo devices are being compromised through exploitation of a remote command execution vulnerability... The log files we have reviewed show that the attackers directly connected to the affected My Book Live devices from a variety of IP addresses in different countries. This indicates that the affected devices were directly accessible from the Internet, either through direct connection or through port forwarding that was enabled either manually or automatically via UPnP.

Additionally, the log files show that on some devices, the attackers installed a trojan with a file named ".nttpd,1-ppc-be-t1-z", which is a Linux ELF binary compiled for the PowerPC architecture used by the My Book Live and Live Duo. A sample of this trojan has been captured for further analysis and it has been uploaded to VirusTotal.

Our investigation of this incident has not uncovered any evidence that Western Digital cloud services, firmware update servers, or customer credentials were compromised. As the My Book Live devices can be directly exposed to the internet through port forwarding, the attackers may be able to discover vulnerable devices through port scanning...

At this time, we recommend you disconnect your My Book Live and My Book Live Duo from the Internet to protect your data on the device by following these instructions on our Knowledge Base. We have heard customer concerns that the current My Cloud OS 5 and My Cloud Home series of devices may be affected. These devices use a newer security architecture and are not affected by the vulnerabilities used in this attack. We recommend that eligible My Cloud OS 3 users upgrade to OS 5 to continue to receive security updates for your device

The Washington Post reports that this week the U.S. government "banned the import of solar panels and other goods made with materials produced by a Chinese company that it accused of using forced laborers from China's Xinjiang region, a move likely to complicate the U.S. push toward clean energy." U.S. Customs and Border Protection issued a withhold release order Thursday barring silicon-based products from the company, Hoshine Silicon, which operates from plants in Xinjiang that have been connected to coercive state labor programs targeting Uyghurs and other minorities, as The Post reported on Thursday.

The order could have widespread impact on the solar industry, which is dominated by Chinese suppliers that source materials from Hoshine, the world's largest producer of metallurgical-grade silicon, a key raw material in solar panels. "Almost the complete solar industry is affected by Hoshine," said Johannes Bernreuter, a research analyst in Germany who studies the solar supply chain... By banning only Hoshine imports, CBP stopped short of targeting Xinjiang producers of another key solar ingredient, polysilicon. Those producers have also been connected to coercive labor programs targeting Uyghurs. In a note to investors, Height Securities described the ban "as a substantive but measured first shot across the bow" by the Biden administration, "which needs solar industry support" as it tries to balance rooting out forced labor in U.S. supply chains and an environmental agenda...

[I]ndustry experts said enforcement could be a challenge given the complexity of the solar supply chain and Hoshine's dominance in the industry. Hoshine has produced metallurgical-grade silicon for at least eight of the world's largest polysilicon makers, according to the company's public statements and annual reports. Analysts say that together these firms account for nearly all of the world's supply of solar-grade polysilicon. The move could also undermine U.S. hopes of cooperating with China on climate change, one of few areas of potential collaboration between the two countries increasingly at loggerheads over human rights and investigating the origin of the covid-19 pandemic... Industry experts say it would be safer for U.S. agents to assume all silicon products entering the United States from China contain at least some material sourced from Hoshine, whose metallurgical-grade silicon is used in a wide range of consumer products, including electronics, cars, chemicals and sealants...

The import ban was the most prominent of several measures the Biden administration took Thursday against China's solar-product suppliers. The Commerce Department also added several Chinese polysilicon producers to an export black list, which bars U.S. entities from exporting technology or other goods to the firms without first obtaining a government license.

Slashdot reader thegarbz writes: While a lot of focus has been on the TPM requirements for Windows 11, Microsoft has since updated its documentation to provide a complete list of supported processors. At present the list includes only Intel 8th Generation Core processors or newer, and AMD Ryzen Zen+ processors or newer, effectively limiting Windows 11 to PC less than 4-5 years old.

Notably absent from the list is the Intel Core i7-7820HQ, the processor used in Microsoft's current flagship $3500+ Surface Studio 2. This has prompted many threads on Reddit from users angry that their (in some cases very new) Surface PC is failing the Windows 11 upgrade check.
The Verge confirms: Windows 11 will only support 8th Gen and newer Intel Core processors, alongside [Intel's 2016-era] Apollo Lake and newer Pentium and Celeron processors. That immediately rules out millions of existing Windows 10 devices from upgrading to Windows 11... Windows 11 will also only support AMD Ryzen 2000 and newer processors, and 2nd Gen or newer [AMD] EPYC chips. You can find the full list of supported processors on Microsoft's site...

Originally, Microsoft noted that CPU generation requirements are a "soft floor" limit for the Windows 11 installer, which should have allowed some older CPUs to be able to install Windows 11 with a warning, but hours after we published this story, the company updated that page to explicitly require the list of chips above.

Many Windows 10 users have been downloading Microsoft's PC Health App (available here) to see whether Windows 11 works on their systems, only to find it fails the check... This is the first significant shift in Windows hardware requirements since the release of Windows 8 back in 2012, and the CPU changes are understandably catching people by surprise.

Microsoft is also requiring a front-facing camera for all Windows 11 devices except desktop PCs from January 2023 onwards.
"In order to run Windows 11, devices must meet the hardware specifications," explains Microsoft's official compatibility page for Windows 11.

"Devices that do not meet the hardware requirements cannot be upgraded to Windows 11."

An anonymous reader quotes a report from PCGamesN: Microsoft has finally debuted Windows 11, and it's not just packing auto HDR and native Android apps. The long-teased DirectStorage API that's meant to cut down loading times on gaming PCs much in the same way the Xbox Velocity Architecture speeds things up on Microsoft's consoles is on its way, and it won't be coming to Windows 10 like we originally thought. The Windows 11 exclusive feature improves communication between your storage device and graphics card, allowing assets to load quicker without having to pass through the CPU first. Naturally, this means more time spent gaming and less time reading the same hints as you move from area to area.

It'll work best with systems that are dubbed 'DirectStorage Optimized', containing the right hardware and drivers for the job. If you're more of the DIY type that prefers to build the best gaming PC yourself, requirements demand an NVMe SSD with 1TB of storage or more. PCIe 4.0 NVMe SSDs and the latest GPUs from Nvidia and AMD will offer a better experience, but DirectStorage will still work with older standards like the third generation PCIe 3.0 -- you won't have much luck with 2.5-inch SATA drives, though. DirectStorage will only work with games built using DirectX 12, so there's no telling how many titles will support the feature when you upgrade to Windows 11 for free later this year.

PuceBaboon writes: Ars Technica is reporting that some owners of Western Digital's My Book network-connected disk drives are experiencing data loss on their devices. The as yet unverified problem appears to be an externally initiated factory-reset, resulting in a loss of all existing data. At this early stage, Western Digital is warning users that they should disconnect their devices from the internet to protect their data. A thread on Western Digital's support forum alerted Ars Technica of the problem. Western Digital representatives write in an email: The incident is under active investigation from Western Digital. We do not have any indications of a breach or compromise of Western Digital cloud services or systems. We have determined that some My Book Live devices have been compromised by a threat actor. In some cases, this compromise has led to a factory reset that appears to erase all data on the device. The My Book Live device received its final firmware update in 2015. At this time, we are recommending that customers disconnect their My Book Live devices from the Internet to protect their data on the device. We have issued the following statement to our customers and will provide updates to this thread when they are available: https://community.wd.com/t/action-required-on-my-book-live-and-my-book-live-duo/268147
UPDATE (6/26): Western Digital wrote Friday that "Some customers have reported that data recovery tools may be able to recover data from affected devices, and we are currently investigating the effectiveness of these tools." After reviewing logs from their affected customers, the company now believes the affected devices were directly accessible from the Internet, allowing attackers to remotely install a malicious Trojan file.

As the My Book Live devices can be directly exposed to the internet through port forwarding, the attackers may be able to discover vulnerable devices through port scanning."

MojoKid writes: AMD's FidelityFX Super Resolution (FSR) PC graphics up-scaling technology is ready for prime-time and the company has allowed members of the press to showcase performance and visuals of the tech in action with a number of game engines. AMD FidelityFX Super Resolution is vendor-agnostic and doesn't require specialized hardware to function like NVIDIA DLSS, which relies on Tensor cores on-board NVIDIA Turing or Ampere GPUs to accelerate neural network models that have been specifically trained on game engines. In contrast, AMD FSR utilizes more traditional spatial upscaling to create a super resolution image from a single input frame, not multiple frames. AMD FSR then employs a library of open-source algorithms that work on sharpening both image edge and texture detail. In game testing at HotHardware, frame rates can jump dramatically with little to no perceptible reduction in image quality, and the technology even works on many NVIDIA GPUs as well. There are currently 19 titles that are available or planned with support for AMD FSR, but with the open nature of the technology and cross-GPU compatibility, game developers theoretically should have significant incentive for adoption to breath new performance into their game titles.

An anonymous reader shares a report: Today's announcement from SiFive comes in two parts; this part is significant as it recognizes that Intel will be enabling SiFive's IP portfolio on its 7nm manufacturing process for upcoming foundry customers. We are expecting Intel to offer a wide variety of its own IP, such as some of the x86 cores, memory controllers, PCIe controllers, and accelerators, however the depth of its third party IP support has not been fully established at this point. SiFive's IP is the first (we believe) official confirmation of specific IP that will be supported. Announced earlier this year by Pat Gelsinger, Intel Foundry Services (or IFS) is one prong of Intel's strategy to realign itself with the current and future semiconductor market. Despite having attempted to become a foundry player in the past, whereby they build chips under contract for their customers, it hasn't really worked out that well -- however IFS is a new reinvigoration of that idea, this time with more emphasis on getting it right and expanding the scope.

Last Thursday, a Canadian company backed by Jeff Bezos, called General Fusion, announced it's building a nuclear fusion facility in the UK. Insider reports: General Fusion and the UK Atomic Energy Authority (UKAEA) announced the project together, which will see General Fusion build a fusion demonstration plant in the village of Culham, near Oxford. The facility will be a proof-of-concept, allowing General Fusion to demonstrate its Magnetized Target Fusion (MTF) technology before going on to build its first commercial facility. According to General Fusion, construction will begin in 2022, and it is expected to be about three years before the plant is able to open.

"This new plant by General Fusion is a huge boost for our plans to develop a fusion industry in the UK, and I'm thrilled that Culham will be home to such a cutting-edge and potentially transformative project," the UK science minister, Amanda Solloway, said in a statement. The BBC reports Bezos has been an investor in General Fusion for over a decade, and the company raised $100 million in its latest funding round.

Bloomberg's Mark Gurman, Apple analyst Ming-Chi Kuo, and leaker Jon Prosser say Apple is working on a completely new, high-end version of the MacBook Air. MacRumors reports: The high-end MacBook Air will feature two USB-C ports and a more powerful Apple silicon chip, according to Gurman. The chip will apparently be a direct successor to Apple's M1 chip, featuring the same number of computing cores, but it will run faster. It is also expected to see an increase in graphics cores from seven or eight to nine or 10. This high-end MacBook Air would sit above the current MacBook Air models with the M1 chip, but below the MacBook Pro. Prosser recently unveiled renders that purport to depict the next-generation MacBook Air based on leaked images.

Prosser says that the MacBook Air will be available in a range of color options, much like the 24-inch iMac, and will feature larger function keys, a smaller trackpad, and redesigned feet on the underside of the machine. The biggest change in terms of design from the current MacBook Air seems to be the loss of its iconic tapered design. Instead, the MacBook Air will become considerably thinner as a whole, Prosser explained. Other features rumored to be coming to next-generation MacBook Air models include a mini-LED display and a MagSafe charging port. Gurman believes that the high-end MacBook Air could launch in the second half of this year at the earliest or in 2022, a timeframe that has been echoed by Prosser.

Boston Dynamics has been purchased by Hyundai in a deal valued at $1.1 billion. According to Motherboard, the deal "sees Hyundai assume an 80 percent controlling stake in the robot company. Softbank will retain a 20 percent stake." From the report: It is hard to tell what Hyundai wants out of Boston Dynamics from the press release, which is laden with technobabble. Robots in car manufacturing are nothing new, but Hyundai says the acquisition is "another major step toward its strategic transformation into a Smart Mobility Solution Provider" such as "autonomous driving, artificial intelligence (AI), Urban Air Mobility (UAM), smart factories and robots," which seems to speak to the company's ambitions beyond car manufacturing. Hyundai says it hopes to "develop advanced technologies that enhance people's lives and promote safety, thereby realizing the progress for humanity."

Apparently, the "progress of humanity" means a lot less of it. To celebrate the purchase, Hyundai released a bizarre hype video featuring a seeing-eye robot dog, a nurse robot dog with a tablet mounted on its head that allows the patient to nod at a doctor who is somewhere else, and a teen dancing with a robot in the street. In other words, Hyundai envisions a lonely future in which social cohesion between humans has broken down and robots are our only friends. That's all bad enough, but why anyone would want a seeing eye robot dog instead of a real dog is beyond comprehension.

According to ComputerBase, graphics card prices have begun to drop as much as 50% in Europe. From a report: Availability has also improved significantly, with sales of most GPU models from both AMD and Nvidia doubling month-over-month. This report comes on the heels of ASRock, a GPU maker, noting that GPU pricing is easing as demand from Chinese cryptocurrency miners wanes. More budget-oriented cards like the Nvidia GeForce RTX 3060 and AMD Radeon RX 6700 XT are seeing the most positive results, with a near 50% drop in price compared to last month. For flagship cards like the RTX 3080 and RX 6800 XT, however, prices haven't moved as much. They have dipped a respectable 10-15% which is still a very positive change considering the shortage issues plaguing the technology industry. In the United States, GPU pricing is slowly catching up to Europe, but it's still going down nonetheless.

Long-time Slashdot reader cusco shares an interesting report from IEEE Spectrum: In 2017, we first wrote about the Chinese startup Unitree Robotics, which had the goal of "making legged robots as popular and affordable as smartphones and drones." Relative to the cost of other quadrupedal robots (like Boston Dynamics' $74,000 Spot), Unitree's quadrupeds are very affordable, with their A1 costing under $10,000 when it became available in 2020. This hasn't quite reached the point of consumer electronics that Unitree is aiming for, but they've just gotten a lot closer: now available is the Unitree Go1, a totally decent looking small size quadruped that can be yours for an astonishingly low $2700.

Speedy, good looking gait, robust, and a nifty combination of autonomous human-following and obstacle avoidance... There are three versions of the Go1: the $2700 base model Go1 Air, the $3500 Go1, and the $8500 Go1 Edu... The top of the line Edu model offers higher end computing, 2kg more payload (up to 5kg), as well as foot-force sensors, lidar, and a hardware extension interface and API access... Battery life is a big question — the video seems to suggest that the Go1 is capable of a three-kilometer, 20-minute jog, and then some grocery shopping and a picnic, all while doing obstacle avoidance and person following and with an occasional payload.
Unitree later provided the reporter more detailed specs:

• The battery life of the robot while jogging is about 1 hour
• It weighs 12kg
• The Super Sensory System includes five wide-angle stereo depth cameras, hypersonic distance sensors, and an integrated processing system
• It's running at 16 core CPU and a 1.5 tflop GPU

Slashdot reader quonset writes: With the heat wave gripping Texas, and in an effort to prevent another collapse of the power grid as happened in February during cold weather, Texas is, for the third day in a row, asking residents to conserve electricity. Some people in the Houston area have come home to find the temperatures in their homes are still warm (in the high 70s to low 80s) despite their air conditioning running all day!
A local Texas reporter tells the tale: The family's smart thermostat was installed a few years ago as part of a new home security package. Many smart thermostats can be enrolled in a program called "Smart Savers Texas." It's operated by a company called EnergyHub. The agreement states that in exchange for an entry into sweepstakes, electric customers allow them to control their thermostats during periods of high energy demand. EnergyHub's list of its clients include TXU Energy, CenterPoint and ERCOT.
They spoke to one Texas resident who obviously wasn't even aware of what he'd agreed to when the smart thermostat was installed. As soon as he found out, he immediately unenrolled from the program, complaining "If somebody else can manipulate this, I'm not for it."

Check out this video footage of the sleek Mayflower 400 slicing through the water, hoping to retrace the historic 1620 journey of the famous ship which carried pilgrims to America. Unfortunately, unlike the real Mayflower, this robotic 21st-century doppelganger "had to turn back Friday to fix a mechanical problem," reports the Associated Press: Nonprofit marine research organization ProMare, which worked with IBM to build the autonomous ship, said it made the decision to return to base "to investigate and fix a minor mechanical issue" but hopes to be back on the trans-Atlantic journey as soon as possible.

With no humans on board the ship, there's no one to make repairs while it's at sea.

Piloted by artificial intelligence technology, the 50-foot (15-meter) Mayflower Autonomous Ship began its trip early Tuesday, departing from Plymouth, England, and spending some time off the Isles of Scilly before it headed for deeper waters.

It was supposed to take up to three weeks to reach Provincetown on Cape Cod before making its way to Plymouth, Massachusetts. If successful, it would be the largest autonomous vessel to cross the Atlantic.

A month ago, Amazon-first gadget brands Aukey and Mpow suddenly and mysteriously disappeared from the giant online retailer's storefront, with almost all their electronics vanishing from Amazon's shelves. Today, popular battery and charger brand RavPower has completely disappeared as well. From a report: All of the company's product listings have disappeared, leaving blank white spaces in RavPower's Amazon storefront. Searches for "RavPower" don't bring up any listings for products made by the company. Existing links to RavPower products either point to Amazon's "Sorry, we couldn't find that page" cute 404 dogs, or listings that read "Currently unavailable." By and large, this is exactly what happened to Aukey, Mpow, and other lesser-known electronics retailers last month -- except here, whoever did this has been a bit more thorough.

CNET News : We'll let Razer have its 5 minutes of E3 glory for the "world's fastest 14-inch gaming laptop," the Razer Blade 14. Razer's simply the first to announce one this size with an AMD Ryzen 9 5900HX -- also Razer's first AMD CPU in the Blade line -- and an Nvidia GeForce RTX 3080 crammed inside. But a svelte, small, no-compromise (well, minimal compromise) gaming laptop from Razer is always welcome. Along with the laptop, the company launched a new wall charger, based on Gallium Nitride rather than silicon, its USB-C 130W GaN Charger. No weird names for that one. The last 14-inch Razer Blade debuted in 2017, and it makes sense that Razer would revive it for the 14-inch laptop renaissance that began around 2020. The 2021 Blade 14, as you'd expect, looks like a somewhat shrunken version of the 15-inch, though it's roughly the same thickness as the 15-inch at 16.8mm.

There will be three models of the Blade 14 at launch. All use the Ryzen 9 5900HX, with the same 1TB SSD, 16GB RAM and 720p webcam, as well as Razer's THX Spatial Audio, HDMI 2.1 and other ports and so on. The entry-level $1,800 model incorporates a 144Hz 1080p screen and an RTX 3060 GPU; for $2,200 you upgrade to an RTX 3070 with a 165Hz 1440p display, and $2,800 bumps that to an RTX 3080. The SSD is upgradable but the RAM is soldered to the motherboard, which is kind of a bummer. The screens support FreeSync Premium adaptive refresh through G-Sync compability mode. Razer rates the battery life at up to 12 hours, though it's likely in the ballpark of 10 hours based on what we've seen elsewhere. As you'd expect, the RTX 3080 isn't being pushed to the max in this system; the GPU power draw can range anywhere from 80 to 150 watts, and Razer takes the middle road at 100 watts. In comparison, the hefty 15-inch Asus ROG Strix Scar we're testing pulls down 130 watts.

Slashdot reader Charlotte Web writes: The "Group of Seven" (or G7) nations are some of the world's largest economies — the U.S. and Canada, the U.K., France, Germany, and Italy, and Japan. On Sunday they pledged $2 billion to help developing countries pivot away from fossil fuels and pledged an "overwhelmingly decarbonized" electricity sector by 2030. The New York Times calls these "major steps in what leaders hope will be a global transition to wind, solar and other energy that does not produce planet-warming carbon dioxide emissions."

Politico's Ryan Heath argues "The language on a 'green revolution' is quite strong — there's plenty of detail missing, but it gives climate campaigners a lot to hit leaders with if they fail to deliver. And it's a big deal for the G-7 to agree to 'to conserve or protect at least 30 percent of our land and oceans by 2030.'"
Other reports from Politico's writers:

• "Boris Johnson admitted that the world's richest economies had not managed to secure a widely advertised 1 billion vaccine doses to send to developing countries. The final communique says the group will deliver 870 million doses over the next year."

• "The G-7 nations called for a 'timely, transparent, expert-led, and science-based WHO-convened' investigation into the origins of Covid-19, including in China. WHO's first crack at an investigation — released in March — called a lab leak 'extremely unlikely,' but China didn't grant access to key documents and Secretary of State Antony Blinken called that investigation 'highly deficient' this morning. The U.S. government remains split between two origin theories."

Bloomberg Businessweek reports on "renewed interest in cables that can power consumers in one country with electricity generated hundreds, even thousands, of miles away in another" and possibly even transcontinental, submarine electricity superhighways: Coal, gas and even nuclear plants can be built close to the markets they serve, but the utility-scale solar and wind farms many believe essential to meet climate targets often can't. They need to be put wherever the wind and sun are strongest, which can be hundreds or thousands of miles from urban centers. Long cables can also connect peak afternoon solar power in one time zone to peak evening demand in another, reducing the price volatility caused by mismatches in supply and demand as well as the need for fossil-fueled back up capacity when the sun or wind fade. As countries phase out carbon to meet climate goals, they'll have to spend at least $14 trillion to strengthen grids by 2050, according to Bloomberg New Energy Finance. That's only a little shy of projected spending on new renewable generation capacity and it's increasingly clear that high- and ultra-high-voltage direct current lines will play a part in the transition.

The question is how international will they be...?
The article points out that in theory, Mongolia's Gobi desert "has potential to deliver 2.6 terawatts of wind and solar power — more than double the U.S.'s entire installed power generation capacity — to a group of Asian powerhouse economies that together produce well over a third of global carbon emissions..." The same goes for the U.S., where with the right infrastructure, New York could tap into sun- and wind-rich resources from the South and Midwest. An even more ambitious vision would access power from as far afield as Canada or Chile's Atacama Desert, which has the world's highest known levels of solar power potential per square meter. Jeremy Rifkin, a U.S. economist who has become the go-to figure for countries looking to remake their infrastructure for the digital and renewable future, sees potential for a single, 1.1 billion-person electricity market in the Americas that would be almost as big as China's. Rifkin has advised Germany and the EU, as well as China...

Persuading countries to rely on each other to keep the lights on is tough, but the universal, yet intermittent nature of solar and wind energy also makes it inevitable, according to Rifkin. "This isn't the geopolitics of fossil fuels," owned by some and bought by others, he says. "It is biosphere politics, based on geography. Wind and sun force sharing...."

If these supergrids don't get built, it will be because their time has both come and gone. Not only are they expensive, politically difficult, and unpopular — they have to cross a lot of backyards — their focus on mega-power installations seems outdated to some. Distributed microgeneration as close to home as your rooftop, battery storage, and transportable hydrogen all offer competing solutions to the delivery problems supergrids aim to solve.
