Mercedes-Benz maker Daimler plans to invest more than 40 billion euros, or $47 billion, between 2022 and 2030 to develop battery-electric vehicles, and be ready for an all-electric car market by 2030. NBC News reports: Outlining its strategy for an electric future, the German luxury carmaker said on Thursday it would, with partners, build eight battery plants as it ramps up EV production, and that from 2025 all new vehicle platforms would only make electric cars. "We really want to go for it ... and be dominantly, if not all electric, by the end of the decade," Chief Executive Ola Kallenius told Reuters, adding that spending on traditional combustion-engine technology would be "close to zero" by 2025. However, Daimler stopped short of giving a hard deadline for ending sales of fossil-fuel cars.

Daimler said that as of 2025, it expects electric and hybrid electric cars to make up 50 percent of sales, earlier than its previous forecast that this would happen by 2030. The carmaker will unveil three electric platforms -- one to cover its range of passenger cars and SUVs, one for vans and one for high-performance vehicles -- that will be launched in 2025. Four of its new battery plants will be in Europe and one in the United States. Daimler said it would announce new European partners for its battery production plans soon.

UnknowingFool writes: An engineering sample of Intel's next flagship processor, the i9-12900K, was shown to beat AMD's current flagship 5950X in Cinebench R20 by 18% in multi-core and 28% in single-core tests. The next generation of Intel processors is believed to use a hybrid big.LITTLE design where 8 of its 16 cores are for low power usage and 8 are for full power. The low power cores only run in single thread where the high power cores can run 2 threads. No official word on pricing or release date from Intel though but engineering samples and B600 motherboards are being sold in China for $1,250 and $1,150, respectively. According to leaker OneRaichu, the results for the 12900K were gathered using water-cooling and without overclocking, so it's possible the final score could be even higher. The rumors suggest the processor will come with 16 cores and 24 threads with a boost clock speed of up to 5.3GHz.

An anonymous reader quotes a report from Threatpost: Researchers have released technical details on a high-severity privilege-escalation flaw in HP printer drivers (also used by Samsung and Xerox), which impacts hundreds of millions of Windows machines. If exploited, cyberattackers could bypass security products; install programs; view, change, encrypt or delete data; or create new accounts with more extensive user rights. The bug (CVE-2021-3438) has lurked in systems for 16 years, researchers at SentinelOne said, but was only uncovered this year. It carries an 8.8 out of 10 rating on the CVSS scale, making it high-severity.

According to researchers, the vulnerability exists in a function inside the driver that accepts data sent from User Mode via Input/Output Control (IOCTL); it does so without validating the size parameter. As the name suggests, IOCTL is a system call for device-specific input/output operations. "This function copies a string from the user input using 'strncpy' with a size parameter that is controlled by the user," according to SentinelOne's analysis, released on Tuesday. "Essentially, this allows attackers to overrun the buffer used by the driver." Thus, unprivileged users can elevate themselves into a SYSTEM account, allowing them to run code in kernel mode, since the vulnerable driver is locally available to anyone, according to the firm.

The printer-based attack vector is perfect for cybercriminals, according to SentinelOne, since printer drivers are essentially ubiquitous on Windows machines and are automatically loaded on every startup. "Thus, in effect, this driver gets installed and loaded without even asking or notifying the user," explained the researchers. "Whether you are configuring the printer to work wirelessly or via a USB cable, this driver gets loaded. In addition, it will be loaded by Windows on every boot. This makes the driver a perfect candidate to target since it will always be loaded on the machine even if there is no printer connected." Affected models and associated patches can be found here and here.

"While HP is releasing a patch (a fixed driver), it should be noted that the certificate has not yet been revoked at the time of writing," according to SentinelOne. "This is not considered best practice since the vulnerable driver can still be used in bring-your-own-vulnerable-driver (BYOVD) attacks." Some Windows machines may already have the vulnerable driver without even running a dedicated installation file, since it comes with Microsoft Windows via Windows Update.

Today, Amaon said it will be upgrading almost every plug-in Echo smart speaker to support Matter, a cross-platform open-source standard coming later this year. This includes most Echo and Echo Dot speakers and every Echo Studio, Echo Show, Echo Plus, and Echo Flex. "In fact, the only Echo smart speakers that won't get upgraded to Matter are the first-gen Echo, first-gen Echo Dot and Echo Tap," reports The Verge. From the report: While the company doesn't provide a timeline for those upgrades, the general idea is that Matter will launch by late 2021, so it shouldn't be long until Amazon's newest and / or more popular devices receive the capability. A bigger question is whether any of them will work as Matter hubs. Google announced in May that in addition to upgrading its Nest devices to Matter, it would allow its devices that support the Thread protocol (like the Nest Wi-Fi, Nest Hub Max, and second-gen Nest Hub) to double as connection hubs for Matter, too, not simply as a voice assistant to control Matter gadgets. But while Amazon's Eero routers were early to adopt Thread, Amazon's Echo smart speakers were not.

An anonymous reader quotes a report from Motherboard: The Federal Trade Commission unanimously voted Wednesday to pursue policies that will make it easier for people to repair their own things. In a vote of 5-0 during a Commission Meeting, the FTC agreed to adopt a policy paper outlining how it planned to enforce rules that keep manufacturers from restricting aftermarket repair. It plans to enforce existing warranty law, coordinate with state and local lawmakers to ensure open markets, and investigate the current repair monopolies for violations of antitrust law. The move comes just weeks after President Joe Biden signed an executive order directing the commission to create right-to-repair rules.

The FTC policy paper outlined a five-pronged approach to the problem. First, it's asking for comments and complaints from the public about bad experiences it's had with repair issues and violated warranty. It's long been illegal under federal law for companies to void warranties based on aftermarket repairs. The problem is that those laws often aren't enforced, though the FTC did take some action on manufacturers who put warranty-void-if-removed stickers on their devices after Motherboard reported on the problem several years ago. "While current law does not provide for civil penalties or redress, the Commission will consider filing suit against violators of the Magnuson-Moss Warranty Act to seek appropriate injunctive relief," the policy paper said.

Next, the FTC said it will look over current repair restrictions for violations of existing antitrust and anti-competition laws. "Finally, the Commission will bring an interdisciplinary approach to this issue, using resources and expertise from throughout the agency to combat unlawful repair restrictions," the policy paper said. "The FTC will also closely coordinate with state law enforcement and policymakers to ensure compliance and to update existing law and regulation to advance the goal of open repair markets." "Manufacturers, be warned: It's time to clean up your act and let people fix their stuff," Nathan Proctor, U.S. PIRG Right to Repair Senior Campaign Director, told Motherboard in an email. "With unanimous support from commissioners, there's a new sheriff in town. The FTC is ready to act to stop many of the schemes used to undermine repair, while support is increasing for new legislation to further crack down."

Tesla plans to open its network of superchargers to other electric vehicles later this year, Chief Executive Officer Elon Musk said on Twitter. From a report: The electric-car maker's fast charging network, with over 25,000 superchargers globally, has given it a competitive edge. Meanwhile, other carmakers have formed alliances or invested in startups for networks as they rush new electric vehicle entrants to market. "We're making our Supercharger network open to other EVs later this year," Musk said on Tuesday, adding that over time Tesla's charging network will be opened to other electric vehicles in all countries.

A new report (PDF) from the Institute for Local Self-Reliance (ILSR) finds that installing rooftop solar panels and community solar systems to serve the equivalent of 30 million American homes would create 1.77 millions jobs and $69 billion electricity bill savings over the next five years. CleanTechnica reports: In addition to creating 1.77 million new solar jobs and reducing energy bills by $69 billion, the report found that enacting the 30 Million Solar Homes policies would over five years: Eliminate global warming air pollution equivalent to closing 48 coal-burning power plants or taking 42 million cars off the road for a year; Increase new solar capacity nationally by 151 GW; and Power the equivalent of 20 million households in marginalized communities with local solar.

In the report, these economic and environmental benefits are broken down by state and congressional district. An interactive map further illustrates the local impacts of the 30 Million Solar Homes proposal and gives viewers an opportunity to share the report with their elected officials.

An anonymous reader quotes a report from ZDNet: iFixit co-founder and CEO Kyle Wiens has exposed how companies including Apple, Samsung, and Microsoft manipulate the design of their products and the supply chain to prevent consumers and third-party repairers from accessing necessary tools and parts to repair products such as smartphones and laptops. Speaking during the Productivity Commission's virtual right to repair public hearing on Monday, Weins took the opportunity to draw on specific examples of how some of the largest tech companies are obstructing consumers from a right to repair.

"We've seen manufacturers restrict our ability to buy parts. There's a German battery manufacturer named Varta that sells batteries to a wide variety of companies. Samsung happens to use these batteries in their Galaxy earbuds ... but when we go to Varta and say can we buy that part as a repair part, they'll say 'No, our contract with Samsung will not allow us to sell that.' We're seeing that increasingly," he said. "Apple is notorious for doing this with the chips in their computers. There's a particular charging chip on the MacBook Pro ... there is a standard version of the part and then there's the Apple version of the part that sits very slightly tweaked, but it's tweaked enough that it's only required to work in this computer, and that company again is under contractual requirement with Apple."

He continued, highlighting that a California-based recycler was contracted by Apple to recycle spare parts that were still in new condition. "California Apple stops providing service after seven years, so this was at seven years and Apple have warehouses full of spare parts, and rather than selling that out in the marketplace -- so someone like me who eagerly would've bought them -- they were paying the recycler to destroy them," Wiens said. Weins also pointed to an example involving a Microsoft Surface laptop. "[iFixit] rated it on our repairability score, we normally rate products from one to 10; the Surface laptop got a zero. It had a glued-in battery ... we had to actually cut our way into the product and destroyed it in the process of trying to get inside," he said.

Since 2006 Baldrson (Slashdot reader #78,598) has been part of the team verifying "The Hutter Prize for Lossless Compression of Human Knowledge," an ongoing challenge to compress a 100-MB excerpt of Wikipedia (approximately the amount a human can read in a lifetime).

"The intention of this prize is to encourage development of intelligent compressors/programs as a path to Artificial General Intelligence," explains the project's web site. 15 years ago, Baldrson wrote a Slashdot post explaining the logic (titled "Compress Wikipedia and Win AI Prize"): The basic theory, for which Hutter provides a proof, is that after any set of observations the optimal move by an AI is find the smallest program that predicts those observations and then assume its environment is controlled by that program. Think of it as Ockham's Razor on steroids.
The amount of the prize also increases based on how much compression is achieved. (So if you compress the 1GB file x% better than the current record, you'll receive x% of the prize...) The first prize was awarded in 2006. And now Baldrson writes with the official news that this Spring another prize was claimed after reaching a brand new milestone: Artemiy Margaritov's STARLIT algorithm's 1.13% cleared the 1% improvement hurdle to beat the last benchmark, set by Alexander Rhatushnyak. He receives a bonus in proportion to the time since the last benchmark was set, raising his award by 60% to €9000. [$10,632 USD]

Congratulations to Artemiy Margaritov for his winning submission!

"Well before China decided to kick out all of its bitcoin miners, they were already leaving in droves, and new data from Cambridge University shows they were likely headed to the United States," reports CNBC: The U.S. has fast become the new darling of the bitcoin mining world. It is the second-biggest mining destination on the planet, accounting for nearly 17% of all the world's bitcoin miners as of April 2021. That's a 151% increase from September 2020. "For the last 18 months, we've had a serious growth of mining infrastructure in the U.S.," said Darin Feinstein, founder of Blockcap and Core Scientific. "We've noticed a massive uptick in mining operations looking to relocate to North America, mostly in the U.S."

This dataset doesn't include the mass mining exodus out of China, which led to half the world's miners dropping offline, and experts tell CNBC that the U.S. share of the mining market is likely even bigger than the numbers indicate... "500,000 formerly Chinese miner rigs are looking for homes in the U.S," said Marathon Digital's Fred Thiel. "If they are deployed, it would mean North America would have closer to 40% of global hashrate by the end of 2022."

America's rising dominance is a simple case of luck meeting preparation. The U.S. has quietly been building up its hosting capacity for years... It also helps that the U.S. is also home to some of the cheapest sources of energy on the planet, many of which tend to be renewable. Because miners at scale compete in a low-margin industry, where their only variable cost is typically energy, they are incentivized to migrate to the world's cheapest sources of power.

Thiel expects most new miners relocating to North America to be powered by renewables, or gas that is offset by renewable energy credits. While Castle Island Ventures founding partner, Nic Carter, points out that U.S. mining isn't wholly renewable, he does say that miners here are much better about selecting renewables and buying offsets. "The migration is definitely a net positive overall," he said. "Hashrate moving to the U.S., Canada, and Russia will mean much lower carbon intensity."

Seven years ago two Google engineers concluded, after four years of study that "Renewable energy technologies simply won't work; we need a fundamentally different approach." (The authors proposed a R&D portfolio pursuing "disruptive" solutions in hydro, wind, solar photovoltaics, and nuclear power, with one Slashdot reader asking "is nuclear going to be acknowledged as the future of energy production?")

But the two engineers — still at Google — recently announced "we're happy to say that we got a few things wrong. In particular, renewable energy systems have come down in price faster than we expected, and adoption has surged beyond the predictions we cited in 2014."

One of them told IEEE Spectrum "It's stunning how rapidly things have been moving since the first article was published," Experts now have a better understanding of how a variety of technologies could be combined to prevent catastrophic climate change, the coauthors say. Many renewable-energy systems, for example, are already mature and just need to be scaled up. Some innovations need significant development, including new processes to produce steel and concrete, and geoengineering techniques to sequester carbon and temporarily reduce solar radiation. The one commonality among all these promising technologies, they conclude, is that engineers can make a difference on a planetary scale...

Concerned about the pessimistic tone of most climate coverage, the authors argue that wise policies, market pressure, and human creativity can get the job done. "When you put the right incentives in place, you capture the ingenuity of the masses," says Fork. "All of us are smarter than any of us."
The Google engineers acknowledge we've already seen a plunge in battery prices to lows not predicted until 2050. (Along with cheap natural gas prices, this cut America's coal consumption in half, lowering emissions.) And fossil fuel consumption has been reduced thanks to cheaper electric heat pumps and electric cars. Other suggestions from their article include:

• Cleaner air travel (including clean hydrogen-powered planes)
• New forms of nuclear power
• Climate policy (including carbon pricing strategies like carbon taxes)

"So, engineers, let's get to work."

America detonated the world's first nuclear device in Alamogordo, New Mexico on July 16, 1945.

On its 76th anniversary, U.S. president Biden issued a proclamation: Many brave men and women have risked their lives in service to our Nation, but few know the story of our "Atomic Veterans" — American military service members who participated in nuclear tests between 1945 and 1962, served with United States military forces in or around Hiroshima and Nagasaki through mid-1946, or were held as prisoners of war in or near Hiroshima or Nagasaki. These veterans served at testing sites like the Bikini Atoll and witnessed the destructive power of nuclear weapons firsthand.

On National Atomic Veterans Day, we recognize and honor the contributions of America's Atomic Veterans for their sacrifice and dedication to our Nation's security, and recommit to supporting our Atomic Veterans and educating ourselves on the role these patriots played in our national story.

Atomic Veterans served our Nation with distinction, but their service came at a great cost. Many developed health conditions due to radiation exposure, yet because they were not able to discuss the nature of their service, they were unable to seek medical care or disability compensation from the Department of Veterans Affairs for their illnesses. Decades later in 1996, the United States Congress repealed the Nuclear Radiation and Secrecy Agreements Act, allowing Atomic Veterans to tell their stories and file for benefits. By then, thousands of Atomic Veterans had died without their families knowing the true extent of their service.

Our Nation has one truly sacred obligation: to properly prepare and equip our troops when we send them into harm's way, and to care for them and their families when they return from service. As Commander in Chief, I am committed to fulfilling our obligation to the Atomic Veterans and their families, and ensuring that all of our Nation's veterans have timely access to needed services, medical care, and benefits. On this National Atomic Veterans Day, our country remembers the service and sacrifices of Atomic Veterans. Their heroism and patriotism will never be forgotten and we always honor their bravery and devotion to duty.
July 16, 2021 was named "National Atomic Veterans Day."

The proclamation ended with a call on all Americans "to observe this day with appropriate ceremonies and activities that honor our Nation's Atomic Veterans whose brave service and sacrifice played an important role in the defense of our Nation."

Matt Stoller: Louis Rossmann is an important YouTube personality who talks about, among other things, the fact that big firms block their customers from repairing equipment so they can extract after-market profits with replacement parts. And he's very much noticed the Biden executive order, which calls for agencies to curtail this practice (as well as the FTC report on it). Rossmann did a series of videos on this order, one of which focused on the order calling for the Pentagon to stop contracting with firms that block soldiers from being able to repair equipment. He cited Elle Ekman's New York Times piece from 2019 on the problem. What's even more interesting than the video are the comments on it, from soldiers angry that they keep encountering this problem in the field. I pulled some of them and published them here.

Pepper, SoftBank's robot, malfunctioned during scripture readings, took breaks in exercise class and couldn't recognize the faces of family members. From a report: Having a robot read scripture to mourners seemed like a cost-effective idea to the people at Nissei Eco, a plastics manufacturer with a sideline in the funeral business. The company hired child-sized robot Pepper, clothed it in the vestments of Buddhist clergy and programmed it to chant several sutras, or Buddhist scriptures, depending on the sect of the deceased. Alas, the robot, made by SoftBank Group, kept breaking down during practice runs. "What if it refused to operate in the middle of a ceremony?" said funeral-business manager Osamu Funaki. "It would be such a disaster." Pepper was fired. The company ended its lease of the robot and sent it back to the manufacturer. After a rash of similar mishaps across Japan, in which Pepper botched its job at a nursing home and gave baseball fans a creepy feeling, some people are saying the humanoid itself will need a funeral soon.

"Because it has the shape of a person, people expect the intelligence of a human," said Takayuki Furuta, head of the Future Robotics Technology Center at Chiba Institute of Technology, which wasn't involved in Pepper's development. "The level of the technology completely falls short of that. It's like the difference between a toy car and an actual car." The robotics unit of SoftBank, a Tokyo-based technology investor, said in late June that it halted production of Pepper last year and was planning to restructure its global robotics teams, including a French unit involved in Pepper's development. Still, the company says the machine shouldn't be sent to the product graveyard. Spokeswoman Ai Kitamura said Pepper is SoftBank's icon and still doing good work as a teacher and a temperature taker at hospitals. She declined to comment on any of its individual mishaps.

SoftBank introduced the humanoid to the world in 2014 and started selling it the next year. "Today might become a day that people 100, 200 or 300 years later would remember as a historic day," SoftBank Chief Executive Masayoshi Son said at the introduction. SoftBank sold the robots to individuals for about $2,000, plus monthly fees for subscription services, and rented them to businesses starting at $550 a month. Japan has had a love affair with humanlike robots going back to Astro Boy, a robot featured in a 1960s animated television series, but there have also been breakups. Honda Motor's Asimo once kicked a soccer ball to then-President Barack Obama. Toshiba's Aiko Chihira, an android with a woman's name and appearance, briefly worked as a department store receptionist. After a while, both disappeared. More recently, a Japanese hotel chain created a robot-operated hotel, with dinosaur-shaped robots handling front-desk duties, only to reverse course after the plan failed to save money and created more work for humans.

The PC market is showing early signs of its growth slowing down, after an impressive run of shipments throughout 2020. From a report: Both IDC and Gartner conclude that growth in the second quarter of PC shipments has slowed this year. Demand for new PCs is still above what we saw before the pandemic hit, but a mixture of softer demand and the effects of the global chip shortage mean it's not growing as quickly. "The market faces mixed signals as far as demand is concerned," says Neha Mahajan, a senior research analyst at IDC. "With businesses opening back up, demand potential in the commercial segment appears promising. However, there are also early indicators of consumer demand slowing down as people shift spending priorities after nearly a year of aggressive PC buying." IDC says more than 83 million PCs were shipped in the second quarter of 2021, while Gartner's own figure is more than 71 million. Gartner does not include Chromebook shipments in its results, but the research firm says "Chromebook shipments were once again strong in the second quarter of 2021." Either way, both firms agree that year-over-year growth in this latest quarter wasn't as strong as 2020's sudden growth.

The official autopsy of the great Texas winter blackout of February 2021 quickly established a clear timeline of events: Electric utilities cut off power to customers and distributors as well as natural gas producers, which in turn triggered a negative feedback loop that sunk the state deeper and deeper into frigid darkness. It's now becoming clear that while millions of Texans endured days of power cuts, the state's gas producers contributed to fuel shortages, allowing pipelines and traders to profit handsomely off them. From a report: Interviews with energy executives and an analysis of public records by Bloomberg News show that natural gas producers in the Permian shale basin began to drastically reduce output days before power companies cut them off. As the flow of gas cratered, everyone scrambled to secure enough supply, sparking one of the wildest price surges in history. Power producers were forced to pay top dollar in the spot market for whatever gas they could find. Soon customers will be saddled with the bill.

And it's a big one: The total comes to about $11.1 billion for a storm that lasted for just five days, according to estimates by BloombergNEF analysts Jade Patterson and Nakul Nair. The cost of gas for power generation alone was about $8.1 billion, or 75 times normal levels. A further $3 billion was spent by utilities providing gas for cooking, heating and fireplaces. The BNEF estimate is based on spot prices at major hubs assessed by S&P Global Platts rather than private contracts, so is likely an upper limit of the total cost. Millions of Texans are now faced with the prospect of paying higher gas prices for years as utilities seek to spread the cost over a decade or more. Texas lawmakers have set aside $10 billion to help natural gas utilities cover their natural gas costs from the storm through low-interest, state-backed bonds.

A special legislative session convened Thursday but the agenda did not include any measures to fix the power grid. This week, Governor Greg Abbott appeared to double down on his early assessment that wind and solar were prime culprits of the freeze. Even though gas failed in its role as a reliable backup fuel during the freeze, Abbott pushed regulators in a letter to strengthen incentives for fossil fuel and nuclear generators while increasing "reliability costs" for intermittent renewable power sources. What Abbott didn't mention was the massive windfall key industry players made during the freeze. Energy Transfer posted its highest quarterly net income on record, more than three times its previous best quarter.

Backblaze CEO Gleb Budman, writing on the company blog: Over the last 14 years, we have worked diligently to keep our costs low and pass our savings on to customers. We've invested in deduplication, compression, and other technologies to continually optimize our storage platform and drive our costs down -- savings which we pass on to our customers in the form of storing more data for the same price.

However, the average backup size stored by Computer Backup customers has spiked 15% over just the last two years. Additionally, not only have component prices not fallen at traditional rates, but recently electronic components that we rely on to provide our services have actually increased in price.

The combination of these two trends, along with our desire to continue investing in providing a great service, is driving the need to modestly increase our prices. The new monthly plan now costs $7, while the yearly plan will set you back by $70.

Drought is putting pressure on California's already stressed-out grid. From a report: As water reservoirs run dry, there's been a significant drop in hydroelectric generation. Without enough water pressure to quickly turn turbine blades, there could be electricity shortages right when residents need it the most. Rolling blackouts have already become a new norm for the state as utilities shut down power lines in an attempt to avoid sparking fires during hot, dry weather. But summertime outages also occur when residents crank up their air conditioners to beat the heat and demand outpaces the available power supply.

"California relies on hydro for so much of its demand, so any drought can put the state in a tight position," said Lindsay Aramayo, an industry economist with the US Energy Information Administration. Hydropower is a significant source of energy for the state. In 2019, it made up about 17 percent of California's electricity mix. And while California is no stranger to drought, this is particularly bad. More than a third of the state is experiencing "exceptional drought," and more than 40 percent of its residents are living under a drought state of emergency.

Robots have a hard time improvising, and encountering an unusual surface or obstacle usually means an abrupt stop or hard fall. But researchers have created a new model for robotic locomotion that adapts in real time to any terrain it encounters, changing its gait on the fly to keep trucking when it hits sand, rocks, stairs and other sudden changes. From a report: Although robotic movement can be versatile and exact, and robots can "learn" to climb steps, cross broken terrain and so on, these behaviors are more like individual trained skills that the robot switches between. Although robots like Spot famously can spring back from being pushed or kicked, the system is really just working to correct a physical anomaly while pursuing an unchanged policy of walking. There are some adaptive movement models, but some are very specific (for instance this one based on real insect movements) and others take long enough to work that the robot will certainly have fallen by the time they take effect.

The team, from Facebook AI, UC Berkeley and Carnegie Mellon University, call it Rapid Motor Adaptation. It came from the fact that humans and other animals are able to quickly, effectively and unconsciously change the way they walk to fit different circumstances. "Say you learn to walk and for the first time you go to the beach. Your foot sinks in, and to pull it out you have to apply more force. It feels weird, but in a few steps you'll be walking naturally just as you do on hard ground. What's the secret there?" asked senior researcher Jitendra Malik, who is affiliated with Facebook AI and UC Berkeley. Certainly if you've never encountered a beach before, but even later in life when you have, you aren't entering some special "sand mode" that lets you walk on soft surfaces. The way you change your movement happens automatically and without any real understanding of the external environment.

The New York Times reports on "an intense policy struggle" in America's national and state governments:

-On one side, large electric utilities and President Biden want to build thousands of miles of power lines to move electricity created by distant wind turbines and solar farms to cities and suburbs.

- On the other, some environmental organizations and community groups are pushing for greater investment in rooftop solar panels, batteries and local wind turbines.

And the result "could lock in an energy system that lasts for decades." At issue is how quickly the country can move to cleaner energy and how much electricity rates will increase... The option supported by Mr. Biden and some large energy companies would replace coal and natural gas power plants with large wind and solar farms hundreds of miles from cities, requiring lots of new power lines. Such integration would strengthen the control that the utility industry and Wall Street have over the grid. "You've got to have a big national plan to make sure the power gets from where it is generated to where the need is," Energy Secretary Jennifer Granholm said in an interview.

But many of Mr. Biden's liberal allies argue that solar panels, batteries and other local energy sources should be emphasized because they would be more resilient and could be built more quickly... In all probability, there will be a mix of solutions that include more transmission lines and rooftop solar panels. What combination emerges will depend on deals made in Congress but also skirmishes playing out across the country...

As millions of California homes went dark during a heat wave last summer, help came from an unusual source: batteries installed at homes, businesses and municipal buildings. Those batteries kicked in up to 6 percent of the state grid's power supply during the crisis, helping to make up for idled natural gas and nuclear power plants. Rooftop solar panels generated an additional 4 percent of the state's electricity... California showed that homes and businesses don't have to be passive consumers. They can become mini power plants, potentially earning as much from supplying energy as they pay for electricity they draw from the grid. Home and business batteries, which can be as small as a large television and as big as a computer server room, are charged from the grid or rooftop solar panels...

Regulators generally allow utilities to charge customers the cost of investments plus a profit margin, typically about 10.5 percent, giving companies an incentive to build power plants and lines... A 2019 report by the National Renewable Energy Laboratory, a research arm of the Energy Department, found that greater use of rooftop solar can reduce the need for new transmission lines, displace expensive power plants and save the energy that is lost when electricity is moved long distances. The study also found that rooftop systems can put pressure on utilities to improve or expand neighborhood wires and equipment.
The director of a Chicago-based environmental nonprofit tells the Times that "Solar energy plus storage is as transformative to the electric sector as wireless services were to the telecommunications sector."

In a weird twist, fossil fuel companies are now joining forces with local groups (including environmental groups) to fight the construction of new power lines.
