An anonymous reader quotes a report from Electrek: Tesla's advanced battery research group in Canada in partnership with Dalhousie University has released a new paper on a new nickel-based battery that could last 100 years while still favorably comparing to LFP cells on charging and energy density. [...] The paper describes a nickel-based battery chemistry meant to compete with LFP battery cells on longevity while retaining the properties that people like in nickel-based batteries, like higher energy density, which enables longer range with fewer batteries for electric vehicles.

The group wrote in the paper's abstract: "Single crystal Li[Ni0.5Mn0.3Co0.2]O2//graphite (NMC532) pouch cells with only sufficient graphite for operation to 3.80 V (rather than [greater than or equal to] 4.2 V) were cycled with charging to either 3.65 V or 3.80 V to facilitate comparison with LiFePO4//graphite (LFP) pouch cells on the grounds of similar maximum charging potential and similar negative electrode utilization. The NMC532 cells, when constructed with only sufficient graphite to be charged to 3.80 V, have an energy density that exceeds that of the LFP cells and a cycle-life that greatly exceeds that of the LFP cells at 40C, 55C and 70C. Excellent lifetime at high temperature is demonstrated with electrolytes that contain lithium bis(fluorosulfonyl)imide (LiFSI) salt, well beyond those provided by conventional LiPF6 electrolytes." The cells showed an impressive capacity retention over a high number of cycles.

The research group even noted that the new cell described in the paper could last a 100 years if the temperature is controlled at 25C: "Ultra-high precision coulometry and electrochemical impedance spectroscopy are used to complement cycling results and investigate the reasons for the improved performance of the NMC cells. NMC cells, particularly those balanced and charged to 3.8 V, show better coulombic efficiency, less capacity fade and higher energy density compared to LFP cells and are projected to yield lifetimes approaching a century at 25C." One of the keys appears to be using an electrolyte with LiFSI lithium salts, and the paper notes that the benefits could also apply to other nickel-based chemistries, including those with no or low cobalt. The paper has been published in the Journal of the Electrochemical Society.

Starting this fall with its locations in California, the Swedish furniture giant Ikea will sell the means to power your Starkvind (that's an air purifier) and Stjarnstatus (that's a fridge) by adding solar panels to the company's offerings. Thankfully, assembly will be handled by the professionals. Curbed reports: To bring photovoltaics -- the technical name for solar panels -- to the people, Ikea is partnering with SunPower, one of the largest solar-energy providers in the country, which will install the rooftop systems and a DC-battery storage unit. As with all solar installations, the cost and energy generated will vary depending on a range of factors, such as the size of the roof and how much sunlight it sees during the day. Incentives like tax credits can also help sweeten the deal, depending on where you live. [...]

The stated goal of Ikea's solar efforts is to zero out the emissions generated to power its plugged-in products, which the company estimates are about 20 percent of its total. Now let's see if Ikea can make solar panels as ubiquitous and affordable for U.S. homes as its Billy bookshelf -- one of which is made every three seconds.

The state of New York will distribute robot companions to the homes of more than 800 older adults. From a report: The robots are not able to help with physical tasks, but function as more proactive versions of digital assistants like Siri or Alexa -- engaging users in small talk, helping contact love ones, and keeping track of health goals like exercise and medication. The scheme is being organized by the New York State Office for the Aging (NYSOFA), and is intended to help address the growing problem of social isolation among the elderly. An estimated 14 million Americans over the age of 65 currently live alone, and this figure is projected to increase over the next decade as the boomer generation ages. Studies have suggested that long-term loneliness is as damaging to an individual's health as smoking.

tomhath shares a report from The New York Times: The United States said on Monday that it would supply Romania with a training simulator in preparation for building a new type of nuclear power generating plant in the country. If an agreement on moving ahead with a power station is reached, Romania could become the first country in Europe, and perhaps in the world, to have such a plant, known as a small modular reactor.

The one in Romania would be built by NuScale Power, a start-up company based in Portland, Ore. The government announced that the plant would be built in Doicesti, at the site of a shuttered coal-fired power plant about 55 miles northwest of Bucharest. [...] NuScale's approach to nuclear energy involves constructing relatively small reactors in factories and then assembling groups of them at the actual site for generating power. The aim is to reduce costs as well as the time required for construction. Conventional modern nuclear plants can cost $10 billion or more.

The plan involves building a power station composed of six of the modular units. The plant would generate 462 megawatts of electricity, making it the size of a medium-size conventional power station. Such a plant might cost around $1.6 billion, according to figures published by the U.S. Embassy in Bucharest. The hope is to have it operating by the end of the decade.

The Spanish government on Tuesday announced plans to invest $13.2 billion to build microchips in the country and "help reduce the dependence of Span and the European Union on other suppliers," reports the Associated Press. From the report: Speaking in Madrid, Deputy Prime Minister and Economy Minister Nadia Calvino said the five-year plan is aimed at enabling Spain to cover every area in the design and production of microchips, which are now considered key to all areas of modern industry. She said the plan was among the most ambitious of the Spanish government's projects to reboot the economy after the COVID-19 pandemic and that it would have an effect on other sectors.

The project was directed at boosting the EU's weak position in microchip production, which Calvino said represented some 10% of the world total. She said this led to a great dependence on a small number of major producers such as Taiwan, the United States, South Korea, Japan and China. Calvino added that "the war in Ukraine makes it a priority to reinforce strategic autonomy in energy, technology, food production as well as cyber security."

Samsung is rumored to be assembling a special task force dubbed "Dream Platform One team" tasked with designing a custom in-house Samsung mobile Application Processor (AP) that can take on Apple Silicon. Neowin reports: It's probably fair to say that Samsung hasn't had the best time with its Exynos offerings when compared against rivals like Qualcomm or Apple. To shake its fortunes up, the company also paired up with AMD for its Exynos 2200 GPU, and results were a mixed bag. Both the AMD RDNA 2 Xclipse 920 graphics and the Exynos 2200 CPU were found to be pretty disappointing in terms of power efficiency as they were not much better than the previous Exynos 2100 offering. In a nutshell, the new CPU was around 5% faster while the AMD graphics was around 17% better, both of which were clearly not enough (via TechAltar on Twitter). However, the company is looking to get real serious and down to business come 2025. The new report coincides with a separate report suggesting that Samsung was working on a custom chipset for its Galaxy S series. The downside is that it's not slated for 2025 and will obviously have to compete against whatever Apple offers at that time.

"AMD's Computex 2022 keynote marks the first appearance of company's new Zen 4-based Ryzen 7000 desktop chip in the flesh," writes Slashdot reader MojoKid. "And in its first quick benchmark tease, it's looking pretty buff." Here's an excerpt from a report via HotHardware: AMD Ryzen 7000-series processors that will be the first to ship with Zen 4 cores will include one or two 5nm Zen 4 CCDs -- topping out at 16 cores, just like Zen 3 -- as well as a new cIOD fabricated on 6nm chip process technology. The new cIOD will include PCIe 5.0 and DDR5 support, as well as an RDNA 2-based GPU for basic display support. [...] Initial performance claims regarding solid state storage weren't the only ones made during AMD's Computex keynote, however. As the keynote was wrapping up, Dr. Su showed two demos powered by a Ryzen 7000 series processor.

AMD Ryzen 7000-series processors that will be the first to ship with Zen 4 cores will include one or two 5nm Zen 4 CCDs -- topping out at 16 cores, just like Zen 3 -- as well as a new cIOD fabricated on 6nm chip process technology. The new cIOD will include PCIe 5.0 and DDR5 support, as well as an RDNA 2-based GPU for basic display support. In the second demo, a custom Ryzen 7000 3D image was being rendered in Blender, with an Intel Core i9-12900K 16-core / 24-thread processor running alongside an AMD Ryzen 7000 series 16-core / 32-thread processor. In the time-lapsed demo, the Ryzen 7000-based system finished the render 31% faster than the Intel system.

While AMD wasn't willing to commit to any specific date, the company did confirm that Zen 4 will be here this year, and well before the holiday shopping season. Dr. Su set a timeframe of "Fall" for availability of the new Ryzen 7000 CPUs, as well as the motherboards that will help enable the entire platform. Slashdot reader UnknowingFool also shared the news (via AnandTech).

CNBC visited a company that burns trash from a California landfill, and then "harnesses steam to make enough electricity to power 18,000 homes in the area" — which turns out to be part of a surprisingly large industry: A portion of the waste comes from companies including American Airlines, Quest Diagnostics, Sunny Delight and Subaru.... Major retailers like Amazon also use this combustion method to dispose of returns they deem unfit to recycle, resell, or donate....

The U.S. is one of the most wasteful developed countries in the world. Of the record 292 million tons of waste generated by Americans each year, more than half is landfilled, about a third is recycled, and 12% is incinerated at waste-to-energy facilities, according to the World Bank. Online commerce poses a particular problem. Not only are internet purchases breaking records in terms of volume, but roughly 20% of items get returned, which is a higher number than for in-store purchases. Returns solutions provider Optoro says U.S. returns generate an estimated 5.8 billion pounds of landfill waste each year.
But the article also points out that more than half of U.S. states define waste-to-energy as a renewable energy source." Unlike landfills, many governments and non-governmental organizations consider it a source of greenhouse gas mitigation. That includes the U.S. Environmental Protection Agency, where Susan Thorneloe leads research on materials management.

U.S. climate experts say these are the three reasons the burning process produces a net reduction of greenhouse gasses. First, it keeps waste out of landfills, which emit methane that the EPA estimates is 86 times greater than carbon dioxide over a 20-year period. Second, waste-to-energy facilities reduce the need for mining because they recover 700,000 tons of metal each year. And finally, they produce energy, reducing the need to burn fossil fuels.... The steam can also be captured and piped up to a mile away to heat or cool entire buildings, like Target Field in Minneapolis....

The EPA estimates that for every megawatt-hour of electricity generated, waste-to-energy emits an average of just over half a metric ton of carbon dioxide equivalent gasses. Landfills emit six times that, and coal plants emit nearly double.
At least some scientists CNBC spoke to said that air pollution technology has advanced so much in the last two decades that most common toxins have largely been eliminated.

"Made In Space, Redwire, and Bigelow, move over," writes long-time Slashdot reader Dr. Crash. "There's yet another 3D printing in space group — and it's not a startup." Mitsubishi Electric just went public with a UV-sensitive resin specially made to print in zero-G and in a hard vacuum — as in outside the airlock.

The polymer is tuned to harden with solar ultraviolet light, so no UV lasers needed (saving power and launch weight).

Their first goal? Printing cubesat parabolic dishes in orbit, so a 300mm cubesat could have what looks like a one-meter dish antenna — or anything else that can be freeform-printed.
This "photopolymerization" technology "specifically addresses the challenge of equipping small, inexpensive spacecraft buses with large structures, such as high-gain antenna reflectors," according to Mitsubishi's announcement — arguing that it also ultimately "enables on-orbit fabrication of structures that greatly exceed the dimensions of launch vehicle fairings."

System76's CEO Carl Richell announced that HP has chosen the Ubuntu-based Pop!_OS operating system to run on its 14-inch developer-focused notebook called "Dev One." Brian Fagioli from BetaNews speculates that a HP acquisition of System76 "could be a possibility in the future -- if this new relationship pans out at least." He continues: HP could be testing the waters with the upcoming Dev One. Keep in mind, System76 does not even build its own laptops, so we could see the company leave the notebook business and focus on desktops only -- let HP handle the Pop!_OS laptops. "We've got you covered. Experience exceptional multi-core performance from the AMD Ryzen 7 PRO processor and multitask with ease. Compile code, run a build, and keep all your apps running with more speed from the 16GB memory. Plus, load and save files in a flash, thanks to 1TB fast PCIe NVMe M.2 storage. We've even added a Linux Super key so shortcuts are a click away. Simply put, HP Dev One is built to help you code better," explains HP.

The company adds, "Pop!_OS is at your service. Create your ideal work experience with multiple tools to help you perform with peak efficiency. Use Stacking to organize and access multiple applications, browsers, and terminal windows. Move, resize, and arrange windows with ease or, let Pop!_OS keep you organized and efficient with Auto-tiling. And use Workspaces to reduce clutter by organizing windows across multiple desktops." Apparently, there will only be one configuration priced at $1,099. So far, no details about a release date have been announced other than "coming soon."

iFixit CEO Kyle Wiens sat down with Ars Technica to discuss the fight for the right to repair. Here's an excerpt from their report: Tech repairs got complicated in 1998 when Congress passed the Digital Millennium Copyright Act [PDF]. Section 1201 of the copyright law essentially made it illegal to distribute tools for, or to break encryption on, manufactured products. Created with DVD piracy in mind, it made fixing things like computers and tractors significantly harder, if not illegal, without manufacturer permission. It also represented "a total sea change from what historic property rights have been," Wiens said. This makes Washington, DC, the primary battleground for the fight for the right to repair. "Because this law was passed at the federal level, the states can't preempt. Congress at the federal level reset copyright policy. This fix has to happen at the US federal level," Wiens told Ars Technica during the Road to Frontiers talk.

The good news is that every three years, the US Copyright Office holds hearings to discuss potential exemptions. Right to repair advocates are hoping Congress will schedule this year's hearing soon. Wiens also highlighted the passing of the Freedom to Repair Act [PDF] introduced earlier this year as critical for addressing Section 1201 and creating a permanent exemption for repairing tech products.

Apple's self-service repair program launched last month marked a huge step forward for the right to repair initiated by a company that has shown long-standing resistance. Wiens applauded the program, which provides repair manuals for the iPhone 12, 13, and newest SE and will eventually extend to computers. He emphasized how hard it is for iFixit to reverse-engineer such products to determine important repair details, like whether a specific screw is 1 or 1.1 mm. [...]

Wiens envisioned a world where gadgets not only last longer but where you may also build relationships with local businesses to keep your products functioning. He lamented the loss of businesses like local camera and TV repair shops extinguished by vendors no longer supplying parts and tools. [...] He also discussed the idea of giving gadgets second and even third lives: An aged smartphone could become a baby monitor or a smart thermostat. "I think we should be talking about lifespans of smartphones in terms of 20, 25 years," Wiens said. The livestream of the discussion can be viewed here.

Citing a report from The Information's Wayne Ma (paywalled), MacRumors reports Apple's long-rumored AR/VR headset is said to feature 14 cameras that enable lifelike avatars with accurate facial expressions. The company is also working with former design chief Jony Ive on the project. From the report: For starters, one of the headset's marquee features is said to be lifelike avatars with accurate facial expressions captured by 14 cameras: "Other challenges, such as incorporating 14 cameras on the headset, have caused headaches for hardware and algorithm engineers. The cameras include those that will track the user's face to ensure virtual avatars accurately represent their expressions and mouth movements, a marquee feature."

The report adds that Apple's former design chief Jony Ive has remained involved with the headset project as an external consultant to the company: "One person familiar with the matter said Ive's consulting work for Apple since he left includes the headset, adding that he is often brought in to help his former team push through their preferences in areas such as battery, camera placement and ergonomics over those of engineers. Two people said even after Ive left Apple, some employees on the headset project were still required to make the trek from Cupertino to San Francisco, where Ive has a home, to get his approval on changes. Ive has continued to tweak the headset's design. While earlier prototypes had the battery in the headband, he prefers a design that would tether the headset to a battery the user wears, similar to Magic Leap's headset design. It couldn't be learned if this approach will make it into the final design."

The initial version of Apple's headset is said to lack a focus on gaming: "Four people who have worked on the project also criticized its lack of focus on gaming, a category of software that appeals to early adopters, which was important to the success of the iPhone and has been a big priority for Meta's VR group. Those people said Rockwell's group almost never mentioned games in internal presentations about possible uses for the headset. Apple isn't developing game controllers for the device and is aiming to use hand tracking or in combination with a clothespin-like finger clip as inputs for the device, multiple people familiar with the project say." On Thursday, Bloomberg reported that Apple executives previewed the upcoming headset to the company's board last week, "indicating that development of the device has reached an advanced stage."

An anonymous reader quotes a report from Ars Technica: One of the best things about electric cars, other than their power trains, immediate torque, and relaxing quiet, is the fact that as the electrical grid becomes cleaner, so too does every EV that uses that grid to charge. That process took a step forward this week with the news that by next year, the Electrify America (EA) charging network will be entirely offset by solar energy.

On Wednesday, EA signed a 15-year agreement with Terra-Gen to purchase electricity from a 75 MW solar farm being built by the latter in San Bernardino County, California. The Electrify America Solar Glow 1 project will break ground later this year, and when it's fully operational in 2023, it should have an annual energy production of 225,000 MWh. That's more than enough to account for the annual energy use of the EA charging network. In fact, EA says that as of April, its electricity is already 100 percent renewable thanks to purchases from various suppliers, but with the commissioning of Solar Glow 1, the charging company should have complete confidence that it's putting more solar energy into the grid than it uses to charge our cars.

An anonymous reader quotes a report from Ars Technica: An upgradeable laptop is only worthwhile if you can actually upgrade it [...], and Framework is making that possible starting today: The company is introducing a new iteration of the Framework Laptop's motherboard that uses 12th-gen Intel CPUs. A brand-new 12th-gen Framework Laptop starts at $1,049 for a Core i5-equipped base model, or $819 for a build-it-yourself kit with no memory or storage. These products will be available for preorder starting today, and shipping will start in July.

The 12th-generation Core processors use Intel's latest Alder Lake CPU architecture, which combines high-performance P-cores and high-efficiency E-cores to maximize performance under heavy load and reduce power usage when your computer is mostly idle. The base Core i5-1240P CPU includes four P-cores and eight E-cores, a big boost in core count compared to the quad-core 11th-gen CPUs. The Core i7-1260P upgrade has the same CPU core count with boosted clock speeds and a small increase in integrated GPU performance, while the top-end Core i7-1280P option will get you six P-cores and eight E-cores.

The rest of the Framework Laptop's hardware is staying mostly the same, though there are a few additional upgrades to be aware of. One is a 2.5Gbps Ethernet expansion card, the first wired LAN module to be available for the laptop. The card is based on Realtek's RTL8156 chipset and will be available "later this year." The company is also releasing a redesigned version of its top cover made with a new CNC manufacturing process that "substantially improv[es] rigidity." The new top cover will be the default option for all Framework Laptops going forward, though you can buy a new cover for your existing Framework Laptop for $89.

An anonymous reader quotes a report from NewsNation: Blackouts could plague a number of states in the U.S. this summer, regulators warn, as a combination of drought, heat, potential cyber attacks, geopolitical conflicts and supply chain problems could disrupt the power supply, according to a grim new report (PDF) from the North American Electric Reliability Corporation (NERC). The regulatory body found that large swathes of the U.S. and parts of Canada are at an elevated or high risk of energy shortfalls during the summer's hottest months.

The Midwest is at especially high risk due to the retirement of older plants, which has caused a 2.3% decrease in capacity from last summer, as well as increased demand, according to NERC. In the Southwest, plummeting river levels may cripple hydropower production, the group warned, and in Texas drought-related heat events could cause extreme energy demand. A NERC map shows all states in the western half of the continental U.S., including North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas are at least under elevated risk of energy shortfalls, with parts of the northeastern-most states under high risk. Many states under the Midcontinent Independent System Operator (MISO), such as Arkansas, Louisiana, Michigan, Wisconsin, Iowa, Minnesota, Iowa, Illinois and Indiana are either entirely or partly at high risk. "Industry prepares its equipment and operators for challenging summer conditions. Persistent, extreme drought and its accompanying weather patterns, however, are out-of-the-ordinary and tend to create extra stresses on electricity supply and demand," said Mark Olson, NERC's manager of Reliability Assessments. "Grid operators in affected areas will need all available tools to keep the system in balance this summer."

The winner of this year's MIT $100K Entrepreneurship Competition is commercializing a new water desalination technology. MIT News reports: Nona Desalination says it has developed a device capable of producing enough drinking water for 10 people at half the cost and with 1/10th the power of other water desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar panel. The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT's Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current.

"Because we can do all this at super low pressure, we don't need the high-pressure pump [used in reverse osmosis], so we don't need a lot of electricity," says Crawford, who co-founded the company with MIT Research Scientist Junghyo Yoon. "Our device runs on less power than a cell phone charger." The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers. The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil and gas separation, and more.

Top Chinese chipmaker Semiconductor Manufacturing International Co. says demand for mobile phones, personal computers and home appliances has dropped "like a rock" and shows no signs of recovering. From a report: Speaking to investors on Friday, CEO Zhao Haijun said the Russia-Ukraine war and China's COVID lockdowns have massively dented demand for consumer electronics and home appliances, which in turn has led to a "serious" adjustment in chip orders for those segments. "Many smartphone, PC and home appliance companies had exposure in Russia and Ukraine, and their revenues [from those markets] are now gone. Sales in their home market [of China] have also fallen due to the COVID situation domestically," Zhao said.

"We cannot yet see an end to the downtrends in these segments," Zhao added. "There are at least 200 million units of smartphones that will disappear suddenly this year and the majority of them are from our domestic Chinese phone makers." Demand for consumer electronics "dropped like a rock, very seriously," the executive said. "Some of our customers are holding more than five months of that type of inventory." However, Zhao said SMIC's factories are still running at 100% capacity, as the company has been allocating resources to products that are still in great shortage, such as power management chips and microcontrollers used in green energy, electric vehicles and industrial applications.

Uber on Monday said it launched pilot food delivery services with autonomous vehicles in two California cities, and said it was adding electric vehicle charging stations into its global driver app. From a report: The announcements are part of Uber's annual product event where the ride-hail and food delivery company showcases the latest updates to its app. Uber announced one food delivery service using autonomous cars, and a separate pilot using sidewalk robots. Both services are available to Uber Eats users in Santa Monica and West Hollywood in California, and consumers will have the ability to opt out of the programs. The autonomous car pilot is in collaboration with Motional, the self-driving joint venture of Hyundai and Aptiv, and was initially announced in December. read more It launched on Monday, Uber and Motional said. Uber said the sidewalk robots are provided by Serve Robotics, a spin-off of delivery company Postmates, which Uber acquired in 2020.

Slashdot reader Hmmmmmm shared this report from Hot Hardware: When Nvidia launched its Ampere Lite Hash Rate (LHR) graphics card with the feared Ethereum anti-mining limiter, the world knew it was only a matter of time before someone or a team cracked it. NiceHash, the company that designed the QuickMiner software and Excavator miner, has finally broken Nvidia's algorithm, restoring LHR graphics cards to their 100% Ethereum mining performance....

Graphics card pricing has been plummeting, and we're starting to see better availability at retailers, with some GPUs selling at or below Manufacturer Suggested Retail Price. So QuickMiner's arrival shouldn't influence the current state of the graphics market unless big corporations want to buy out everything in sight for the last push before Ethereum's transition to Proof-of-Stake (PoS), often referred to as "The Merge," is complete. We see that as unlikely, considering current profitability even on a 3080 Ti sits at around $3.50 per day and would still need nearly a year to break even at current rates. Initially scheduled for June, The Merge won't finalize until "the few months after," as Ethereum developer Tim Beiko has expressed on Twitter.

It will be interesting to see if Nvidia responds to this with updated drivers or implements LHRv3 in the remaining GPUs. However, it's perhaps not worth the effort at this point, and all existing LHRv2 and earlier cards can just stay on current drivers for optimized mining performance.

Friday a heat wave hit Texas — prompting the non-profit that manages power for Texas's 26 million customers to...ask them to use less of it.

"The Electric Reliability Council of Texas (ERCOT) made the appeal in a statement Friday, saying that soaring temperatures increased demand and caused six power generation facilities to trip offline," reports CNN. "That resulted in the loss of about 2,900 megawatts of electricity."

The statement asks Texans "to conserve power when they can by setting their thermostats to 78-degrees or above and avoiding the usage of large appliances (such as dishwashers, washers and dryers) during peak hours between 3 p.m. and 8 p.m. through the weekend." CNN reports: The appeal comes as record temperatures across most of the southern U.S. this weekend are expected to worsen a deepening drought. From Phoenix to Amarillo, Texas, record temperatures are expected to reach triple digits, with a chance for some parts of Texas to break daily records over the next seven days.

ERCOT came under scrutiny last year after record cold temperatures in February caused the state's highest electricity demand and more than 200 people died during the power crisis, with the most common cause of death being hypothermia. In March 2021, ERCOT's president and CEO, Bill Magness, was fired following widespread power outages during a series of winter storms that left many residents in the dark for days. Now the heat is testing Texas' power grid....

Temperatures from the mid-90s to the low 100s are expected on Sunday, with much of central and western Texas reaching 100 to 105 degrees — approximately 10 to 15 degrees above average.
