Long-time Slashdot reader schwit1 shares the announcement of a new report from the International Energy Forum: The seemingly universal presumption persists that the copper needed for the green transition will somehow be available... This paper addresses this issue by projecting copper supply and demand from 2018 to 2050 and placing both in the historical context of copper mine output... Just to meet business-as-usual trends, 115% more copper must be mined in the next 30 years than has been mined historically until now. To electrify the global vehicle fleet requires bringing into production 55% more new mines than would otherwise be needed... Our main purpose... is to communicate the magnitude of the copper mining challenge to the broader public that is less familiar with upstream resource issues. "On the other hand, hybrid electric vehicle manufacture would require negligible extra copper mining..." the report points out. Wikipedia describes the non-profit as a 73-country organization promoting dialogue about the world's energy needs. The group's announcement ends with a hope that the report "will promote discussion and formulation of alternative policies to be certain the developing world can catch up with the developed world while global initiatives advance with the green energy transition."

An anonymous reader quotes a report from Bloomberg: California expects to avoid rolling blackouts this summer as new solar plants and large batteries plug into the state's grid at a rapid clip. The state's electricity system has been strained by years of drought, wildfires that knock out transmission lines and record-setting heat waves. But officials forecast Wednesday new resources added to the grid in the last four years would give California ample supplies for typical summer weather. Since 2020, California has added 18.5 gigawatts of new resources. Of that, 6.6 gigawatts were batteries, 6.3 gigawatts were solar and 1.4 gigawatts were a combination of solar and storage. One gigawatt can power about 750,000 homes. In addition, the state's hydropower plants will be a reliable source of electricity after two wet winters in a row ended California's most recent drought. Those supplies would hold even if California experiences another heat wave as severe as the one that triggered rolling blackouts across the state in August 2020, officials said in a briefing Wednesday. In the most dire circumstances, the state now has backup resources that can supply an extra 5 gigawatts of electricity, including gas-fired power plants that only run during emergencies.

Data centers could use up to 9% of total electricity generated in the United States by the end of the decade, more than doubling their current consumption, as technology companies pour funds into expanding their computing hubs, the Electric Power Research Institute said on Wednesday. From a report: Depending on the adoption pace of technology such as generative artificial intelligence, which is fueling the expansion of data centers, and the energy efficiency of new centers, the estimated annual growth rate of electricity use by the industry ranges from 3.7% to 15% through 2030, the institute's analysis said. The institute is a U.S.-based research organization funded by energy and government organizations. Data centers, along with expanding domestic manufacturing and electrification of transportation, are lifting the U.S. electricity industry out of two decades of flat growth. The centers require massive amounts of power for high-intensity computing and cooling systems, with a new large data center requiring the same amount of electricity needed to power 750,000 homes, according to numerous energy company earnings calls this year.

This week the Washington Post noted that just last year nearly 1.2 million more electric vehicles were sold in America, "accounting for over 7 percent of total new car sales and a new national record." But "data show that EV sales are far outpacing growth in the U.S. charging network... In 2016, there were seven electric cars for each public charging point; today, there's more than 20 electric cars per charger." The article points out that 80% of America's EV's are just charging at home, according to the U.S. Energy Department. (Which seems to leave one public charger for every four EVs that don't charge at home.) And the article notes several other important caveats: Experts say that there is no "magic number" for the best ratio of EVs on the road to public chargers. "It absolutely depends on the local landscape," said Peter Slowik, U.S. passenger vehicles lead for the International Council on Clean Transportation. Globally, there is about 1 public charger for every 11 EVs, according to the International Energy Agency. But in countries where there are more single-family homes and garages, the ratio could be lower.... In a way, the United States' slow charging build-out could be a benefit in the long-term: Many automakers have now promised to switch to Tesla's charging connector in the next few years, which could help put most cars on the same system. Not everyone agrees there is a delay. Slowik says that his team's research shows that the United States is on-track for building out the charging needed over the next eight years. An increase in the number of EVs per public charger is a natural part of the adoption process, he argues, that will subside with more sales and as more chargers come online. Still, the article argues if Americans continue buying electric cars, public chargers will be essential "to support long road trips, help apartment-dwellers go electric and alleviate overnight pressure on electricity grids." Today U.S. Transportation Secretary Pete Buttigieg reiterated America's commitment to having a national network of 500,000 charges by 2030, saying the country is at "the absolute very, very beginning stages of the construction to come."

An anonymous reader quotes a report from Markets Insider: Sunny days in Germany mean gray clouds for solar profitability as the nation's dive into renewables has left it with too much energy. According to a note from SEB Research, in the past 10 days, solar producers have had to take an 87% price cut during production hours. In fact, when production peaks, prices have slid well below zero. On average, the price received was 9.1 euros per megawatt-hour, significantly under the 70.6 euros paid during non-solar-power hours. "This is what happens to power prices when the volume of unregulated power becomes equally big or bigger than demand: Prices collapse when unregulated power produces the most," the Swedish bank wrote on Tuesday. Last year's record wave of solar installations are what's driving Germany's price "destruction" as inventory outpaces consumption. While total solar capacity topped 81.7 gigawatts by 2023's end, demand load only reached 52.2 gigawatts, noted SEB chief commodities analyst Bjarne Schieldrop. The difference between the two actually widens even more in the summer, a season of peak production and lower demand. This also means that consumers are not necessarily benefiting from the low prices, as they typically consume more energy in non-solar hours. Unless new installations are spurred on by subsidies or power purchase agreements, oppressed profitability could eventually halt Germany's solar expansion, Schieldrop said. Instead, focus is likely to move onto improvements that will make more use of the energy produced, such as investments in batteries and grid infrastructure. "This will over time exhaust the availability of 'free power' and drive solar-hour-power-prices back up," Schieldrop wrote. "This again will then eventually open for renewed growth in solar power capacity growth."

An anonymous reader quotes a report from Electrek: In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California's main grid for 69 of the past 75 days. Stanford University professor of civil and environmental engineering Mark Z. Jacobson continues to track California's renewables performance – and it's still exciting. In an update today on Twitter (X), Jacobson reports that California has now exceeded 100% of energy demand with renewables over a record 45 days straight, and 69 out of 75. [...] Jacobson predicted on April 4 that California will entirely be on renewables and battery storage 24/7 by 2035. California passed a law that commits to achieving 100% net zero electricity by 2045. Will it beat that goal by a decade? We hope so. It's going to be exciting to watch.

According to the Solar Energy Industries Association (SEIA), the U.S. has officially surpassed 5 million solar installations. "The 5 million milestone comes just eight years after the U.S. achieved its first million in 2016 -- a stark contrast to the four decades it took to reach that initial milestone since the first grid-connected solar project in 1973," reports Electrek. From the report: Since the beginning of 2020, more than half of all U.S. solar installations have come online, and over 25% have been activated since the Inflation Reduction Act became law 20 months ago. Solar arrays have been installed on homes and businesses and as utility-scale solar farms. The U.S. solar market was valued at $51 billion in 2023. Even with changes in state policies, market trends indicate robust growth in solar installations across the U.S. According to SEIA forecasts, the number of solar installations is expected to double to 10 million by 2030 and triple to 15 million by 2034. The residential sector represents 97% of all U.S. solar installations. This sector has consistently set new records for annual installations over the past several years, achieving new highs for five straight years and in 10 out of the last 12 years. The significant growth in residential solar can be attributed to its proven value as an investment for homeowners who wish to manage their energy costs more effectively. California is the frontrunner with 2 million solar installations, though recent state policies have significantly damaged its rooftop solar market. Meanwhile, other states are experiencing rapid growth. For example, Illinois, which had only 2,500 solar installations in 2017, now boasts over 87,000. Similarly, Florida has seen its solar installations surge from 22,000 in 2017 to 235,000 today. By 2030, 22 states or territories are anticipated to surpass 100,000 solar installations. The U.S. has enough solar installed to cover every residential rooftop in the Four Corners states of Colorado, Utah, Arizona, and New Mexico.

Longtime Slashdot reader necro81 writes: The U.S. Federal Energy Regulatory Commission (FERC), which controls interstate energy infrastructure, approved a rule Monday that should boost new transmission infrastructure and make it easier to connect renewable energy projects. (More coverage here, here, and here.) Some 11,000 projects totaling 2,600 GW of capacity are in planning, waiting to break ground, or connect to the grid. But they're stymied by the need for costly upgrades, or simply waiting for review. The frustrations are many. Each proposed project undergoes a lengthy grid-impact study and assessed the cost of necessary upgrades. Each project is considered in isolation, regardless of whether similar projects are happening nearby that could share the upgrade costs or auger different improvements. The planning process tends to be reactive -- examining only the applications in front of them -- rather than considering trends over the coming years. It's a first-come, first-served queue: if one project is ready to break ground, it must wait behind another project that's still securing funding or permitting. Two years in development, the dryly-named Improvements to Generator Interconnection Procedures and Agreements directs utility operators to plan infrastructure improvements with a 20-yr forecast of new energy sources and increased demand. Rather than examining each project in isolation, similar projects will be clustered and examined together. Instead of a First-Come, First-Served serial process, operators will instead examine First-Ready, allowing shovel-ready projects to jump the queue. The expectation is that these new rules will speed up and streamline the process of developing and connecting new energy projects through more holistic planning, penalties for delays, sensible cost-sharing for upgrades, and justification for long-term investments.

Researchers believe they've discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging. The new find needs optimization but has the potential to help power electric vehicles. * An anonymous reader shared this report from Popular Mechanics: In a study published in Science, lead author Sang-Hoon Bae, an assistant professor of mechanical engineering and materials science, demonstrates a novel heterostructure that curbs energy loss, enabling capacitors to store more energy and charge rapidly without sacrificing durability... Within capacitors, ferroelectric materials offer high maximum polarization. That's useful for ultra-fast charging and discharging, but it can limit the effectiveness of energy storage or the "relaxation time" of a conductor. "This precise control over relaxation time holds promise for a wide array of applications and has the potential to accelerate the development of highly efficient energy storage systems," the study authors write. Bae makes the change — one he unearthed while working on something completely different — by sandwiching 2D and 3D materials in atomically thin layers, using chemical and nonchemical bonds between each layer. He says a thin 3D core inserts between two outer 2D layers to produce a stack that's only 30 nanometers thick, about 1/10th that of an average virus particle... The sandwich structure isn't quite fully conductive or nonconductive. This semiconducting material, then, allows the energy storage, with a density up to 19 times higher than commercially available ferroelectric capacitors, while still achieving 90 percent efficiency — also better than what's currently available.

The Royal Institution of Australia is a national non-profit hub for science communication, publishing the science magazine Cosmos four times a year. This month they argued that small modular nuclear reactors "don't add up as a viable energy source." Proponents assert that SMRs would cost less to build and thus be more affordable. However, when evaluated on the basis of cost per unit of power capacity, SMRs will actually be more expensive than large reactors. This 'diseconomy of scale' was demonstrated by the now-terminated proposal to build six NuScale Power SMRs (77 megawatts each) in Idaho in the United States. The final cost estimate of the project per megawatt was around 250 percent more than the initial per megawatt cost for the 2,200 megawatts Vogtle nuclear power plant being built in Georgia, US. Previous small reactors built in various parts of America also shut down because they were uneconomical. The cost was four to six times the cost of the same electricity from wind and solar photovoltaic plants, according to estimates from the Australian Commonwealth Scientific and Industrial Research Organisation and the Australian Energy Market Operator. "The money invested in nuclear energy would save far more carbon dioxide if it were instead invested in renewables," the article agues: Small reactors also raise all of the usual concerns associated with nuclear power, including the risk of severe accidents, the linkage to nuclear weapons proliferation, and the production of radioactive waste that has no demonstrated solution because of technical and social challenges. One 2022 study calculated that various radioactive waste streams from SMRs would be larger than the corresponding waste streams from existing light water reactors... Nuclear energy itself has been declining in importance as a source of power: the fraction of the world's electricity supplied by nuclear reactors has declined from a maximum of 17.5 percent in 1996 down to 9.2 percent in 2022. All indications suggest that the trend will continue if not accelerate. The decline in the global share of nuclear power is driven by poor economics: generating power with nuclear reactors is costly compared to other low-carbon, renewable sources of energy and the difference between these costs is widening.

A tokamak in France achieved a new record in fusion plasma by using tungsten to encase its reaction, which enabled the sustainment of hotter and denser plasma for longer periods than previous carbon-based designs. Quartz reports: A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA). WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak's interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible. "These are beautiful results," said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. "We have reached a stationary regime despite being in a challenging environment due to this tungsten wall."

ArchieBunker quotes a report from Bloomberg: Texas electricity prices soared almost 100-fold as a high number of power-plant outages raised concerns of a potential evening shortfall. Spot prices at the North Hub, which includes Dallas, jumped to more than $3,000 a megawatt-hour just before 7 p.m. local time, versus about $32 at the same time Tuesday, according to data from the Electric Reliability Council of Texas. This morning, Ercot, as the state's main grid operator is known, issued a "watch" for a potential capacity reserve shortage from about 7-9 p.m., meaning the buffer of spare supplies could fall to low enough levels to call on back-up generation, cancel or delay outages or curb usage. The conditions are the tightest of the year so far and raises the risk of prices rising to the $5,000 cap -- which they last did on April 16, when Ercot also warned of a potential shortfall. Unusually hot weather in the region has boosted demand for cooling and lowered the efficiency of many power plants. Wind output has also fallen from a day earlier and there are more outages. "Ercot has not called for conservation this evening," it said by email. "The grid is operating under normal conditions at this time."

Renewable energy accounted for more than 30% of the world's electricity for the first time last year, according to climate thinktank Ember. The Guardian reports: Clean electricity has already helped to slow the growth in fossil fuels by almost two-thirds in the past 10 years, according to the report by climate thinktank Ember. It found that renewables have grown from 19% of electricity in 2000 to more than 30% of global electricity last year. Solar was the main supplier of electricity growth, according to Ember, adding more than twice as much new electricity generation as coal in 2023. It was the fastest-growing source of electricity for the 19th consecutive year, and also became the largest source of new electricity for the second year running, after surpassing wind power. The first comprehensive review of global electricity data covers 80 countries, which represent 92% of the world's electricity demand, as well as historic data for 215 countries. The surge in clean electricity is expected to power a 2% decrease in global fossil fuel generation in the year ahead, according to Ember. [...] World leaders are aiming to grow renewables to 60% of global electricity by 2030 under an agreement struck at the UN's Cop28 climate change conference in December. This would require countries to triple their current renewable electricity capacity in the next six years, which would almost halve power sector emissions.

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm. The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator. Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

A new battery from Energizer comes with "color alert technology" to alert parents if their child has swallowed one. When the coin lithium battery comes into contact with saliva, it activates a blue dye "so parents and caregivers know that medical attention could be required," reports the New York Times. The battery also features more secure packaging and a nontoxic bitter coating. From the report: The new coin lithium battery features more secure packaging, a nontoxic bitter coating to discourage swallowing and "color alert technology" that activates a blue dye when the battery comes into contact with moisture, like saliva, so parents and caregivers know that medical attention could be required. The new battery was announced in a video last week by Energizer and Trista Hamsmith, whose 18-month-old daughter died after swallowing a button battery from a remote control. Ms. Hamsmith founded a nonprofit organization focused on children's safety, successfully advocated for legislation, known as Reese's Law, that requires a secure compartment of the batteries in products that use them as well as stronger warning labels on all packaging, and is now working to make the batteries themselves safer. Ingested coin or button batteries result in thousands of emergency hospital visits each year, according to the U.S. Consumer Product Safety Commission, which notes that "the consequences of a child swallowing a battery can be immediate, devastating and deadly." "A button cell battery can burn through a child's throat or esophagus in as little as two hours if swallowed," according to the agency. Secure packaging and bitter coatings for batteries have long existed, but "the massive breakthrough here is the color alert technology, which helps give caretakers that indicator that something has happened," Jeff Roth, the global category leader for batteries at Energizer, said in an interview on Wednesday. "The most significant part about this is getting help early in the process," he said. "That's really what the color alert technology allows the family to do."

AmiMoJo shares a report from Tech Times: China has reached a major landmark in green transportation with the launch of the world's largest fully electric container ship. Developed and manufactured by China Ocean Shipping Group (Cosco), the vessel is now operating a regular service route between Shanghai and Nanjing, aiming to reduce emissions significantly along its journey. The Greenwater 01, an all-electric container ship, is positioning itself to be a shipping industry pioneer. Equipped with a main battery exceeding 50,000 kilowatt-hours, the vessel can accommodate additional battery boxes for longer voyages. These battery boxes, each containing 1,600 kilowatt-hours of electricity and similar in size to standard 20-foot containers, provide flexibility in extending the ship's travel range. With 24 battery boxes onboard, the Greenwater 01 can complete a journey consuming 80,000 kilowatt-hours of electricity. This is equivalent to saving 15 tons of fuel compared to a standard container ship, highlighting the efficiency of electric propulsion systems. According to Cosco, the vessel can reduce CO2 emissions by 2,918 tons per year, which is equivalent to taking 2,035 family cars off the road or planting 160,000 trees.

An anonymous reader quotes a report from Bloomberg: U.S. wind power slipped last year for the first time in a quarter-century due to weaker-than-normal Midwest breezes, underscoring the challenge of integrating volatile renewable energy sources into the grid. Power produced by turbines slipped 2% in 2023, even after developers added 6.2 gigawatts of new capacity, according to a government report Tuesday. The capacity factor for the country's wind fleet -- how much energy it's actually generating versus its maximum possible output -- declined to an eight-year low of 33.5%. Most of that decline was driven by the central US, a region densely dotted with turbines. Wind is a key component of the effort to cut carbon emissions, but the data highlights the downside of relying on intermittent energy sources tied to the effects of global weather. Last year's low wind speeds came during El Nino, a warming of the equatorial Pacific that tends to weaken trade winds. La Nina, the Pacific cooling pattern that dominated in 2022 and is poised to return later this year, usually has the opposite effect. The U.S. Energy Information Administration shared the findings in a report published earlier today.

An anonymous reader shared this report from CNN: Five times the size of Paris. Visible from space. The world's biggest energy plant. Enough electricity to power Switzerland. The scale of the project transforming swathes of barren salt desert on the edge of western India into one of the most important sources of clean energy anywhere on the planet is so overwhelming that the man in charge can't keep up. "I don't even do the math any more," Sagar Adani told CNN in an interview last week. Adani is executive director of Adani Green Energy Limited (AGEL). He's also the nephew of Gautam Adani, Asia's second richest man, whose $100 billion fortune stems from the Adani Group, India's biggest coal importer and a leading miner of the dirty fuel. Founded in 1988, the conglomerate has businesses in fields ranging from ports and thermal power plants to media and cements. Its clean energy unit AGEL is building the sprawling solar and wind power plant in the western Indian state of Gujarat at a cost of about $20 billion. It will be the world's biggest renewable park when it is finished in about five years, and should generate enough clean electricity to power 16 million Indian homes... [T]he park will cover more than 200 square miles and be the planet's largest power plant regardless of the energy source, AGEL said. CNN adds that the company "plans to invest $100 billion into energy transition over the next decade, with 70% of the investments ear-marked for clean energy."
