To fight off predators of the humpback chub, a threatened fish native to the river, Glen Canyon Dam in northern Arizona would need to do what is known as a "cool mix flow," where cold water is released from deep in its reservoir to cool the river below. But there are no hydropower turbines in the cool, deep section, so significant power generation would be lost.
After six days of trying to avoid an overheating chemical tank erupting into a giant fireball or spilling thousands of gallons of toxic substances at an aerospace facility in Garden Grove, Orange County leaders announced Tuesday that the risk of catastrophic explosion had largely been eliminated. Local authorities lifted a large section of the evacuation zone surrounding GKN Aerospace and allowed tens of thousands of residents to return.
ContourGlobal, the independent power producer backed by KKR, has inaugurated a nearly $500 million solar-and-storage facility in Chile's Atacama desert that stores daytime solar energy and delivers it after sundown. The Victor Jara hybrid plant combines 231 megawatt-peak of photovoltaic capacity with 1.3 gigawatt-hours of battery storage, capable of delivering 200 megawatts of power for up to 6.5 hours at night. ContourGlobal calls it Latin America's longest-duration utility-scale battery system.
Hidden plumbing errors are sending untreated household sewage into rivers, polluting waterways without residents' knowledge. One south-west London river has been badly affected by these misconnections. A misconnection happens when wastewater is incorrectly diverted into surface drains, leading to pollution in nearby waterways. Pollutants may include raw sewage, chemicals and physical debris which are harmful to wildlife and lead to further degradation of river ecosystems, according to Dr Isobel Ollard from the South East Rivers Trust (SERT).
Even small solar panels are expensive, so they need to last a long time in order to make their money back. Take my EcoFlow 400W flexible panel . This retails for $550. If you take the average price for a kWh of electricity in the US (let's say $0.19), combine that with the average amount of peak sunshine (let's say 5 hours), and allow for losses through inefficiencies, this panel can make about 1.5 kWh a day, or just under 30 cents a day of power.
The local authority refused planning permission in July last year, stating that "the applicant has not demonstrated that sufficient archaeological investigations have been undertaken to guide the proposed development towards preserving in-situ potential archaeological features and thereby safeguarding archaeological heritage." The general area features a number of standing stones, fulacht fiadh (Bronze Age cooking pits) and other objects of archaeological interest.
Less than 2% of Americans can put plastic film in their curbside recycling bin, according to The Recycling Partnership. Meanwhile, the country generates millions of pounds of bags, pallet wrap, bubble mailers, and dry cleaner sleeves every year that machinery at materials recovery facilities is designed to reject. The plastic film problem has been the recycling industry's white whale for three decades - too contaminated for most processors, too light for most economics.
Wicklow's coastline has been left out of a key funding stream for invasive species control and dune protection, despite being one of the most erosion vulnerable stretches in the country. The latest allocations under the Local Biodiversity Action Fund (LBAF) show that Wicklow will receive almost €97,000 for four biodiversity projects, but none of them relate to the county's beaches, dune systems or coastal habitats.
Cunlaghfadda Green Energy Limited is seeking a 10-year planning permission for the proposed project, which will be built across the townlands of Knockroe, Cunlaghfadda, Harefield, Cloonbaul and Knockaunakill.
Crude production had plummeted to 567,000 barrels per day, barely more than a quarter of the roughly 2 million barrels pumped daily at the field's peak two decades earlier. The decline stoked concerns that the Trans Alaska Pipeline System, built to carry the state's oil bounty to the continental US, might stop operating. Engineers even worried that slow-moving crude would congeal inside the pipeline, creating waxy buildup that could turn TAPS into the world's biggest tube of ChapStick.
Drivers are facing rising fuel costs as conflict in Iran sends oil prices soaring. Photograph: Mike Kemp/In Pictures/Getty $30m an hour: that's the pure, unearned profits banked by the world's top 100 oil and gas companies in the first month of the conflict in Iran, purely due to the spike in the oil price. I revealed this exclusive analysis, commissioned by the Guardian, in April while it was based on the best data in the industry, it was an estimate. Now the first numbers are in, and that $30m may have been a major underestimate.
When 53-year-old Agbar Mohammad pulled into a petrol station in Fiji in May, he was expecting a queue. Instead, it was almost empty. I could only see one or two cars at the service station, which was very unusual, Mohammad says. The reason became clear very quickly: as Mohammad filled his car, the numbers on the fuel pump climbed so much faster than the needle on his dashboard. Normally he would put in about $40 of fuel, but this time $100 barely got his 60-litre tank halfway full.
Plug-in solar systems, also known as balcony solar, are easy, plug-and-play solar panels that include an inverter and small battery. The system connects to a home's standard 120-volt outlet and automatically flows the electricity from the battery to the nearest running appliance. These systems are small and portable, and aren't meant to replace grid electricity or dependency on utility companies. Instead, they generate anywhere between 200W and 1,800W, but are an easy solution to reduce energy costs with an affordable investment.
Heavy, prolonged rainfall in southern and central China has resulted in weather warnings for flash flooding, landslides and waterlogging. The band of rainfall spanned 1,000km (620 miles) and steadily moved eastwards across the regions on Tuesday. It was a slow-moving band of rain, formed from the convergence of multiple bands originating from the Bay of Bengal, South China Sea and the Pacific Ocean. Coupled with low wind speeds, high daily and hourly rainfall totals have been recorded, with as much as 75mm locally in Hunan, 85mm in Anhui in a 24-hour period and 95mm on the island of Hainan.
The National Diaper Bank Network (NDBN) Diaper Check 2024 found that 46 percent of U.S. families with children under four reported diaper insecurity, meaning they could not always afford enough diapers to keep a child clean and dry. That share has climbed from roughly one-third a decade earlier. The Urban Institute estimates nearly 8 million American children live in households that struggle to afford diapers. Diapers are not covered by SNAP or WIC, and in 23 states, they are still taxed at rates as high as 7 percent, though Missouri, Nevada, and Alabama all eliminated or paused their diaper taxes in 2025.
The Trump administration on Thursday loosened federal rules that require grocery stores and air-conditioning companies to reduce greenhouse gases used in cooling equipment, a step President Donald Trump said would help lower grocery costs. Trump, at a White House ceremony, said the action by the Environmental Protection Agency would "substantially lower costs for consumers" by delaying costly restrictions that limit the type of refrigerants U.S. businesses and families can use.
