California moves to ban sales of gas-powered cars by 2035
California — the state that created the U.S. car culture — will ban all internal combustion-engine cars and passenger trucks starting in 2035. In a Wall Street Journal report, Gov. Gavin Newsom signed an executive order on Sept. 23, which allows the California Air Resources Board to develop regulations for vehicle sales to meet emission targets over […]

Study: Benign volcanoes may be more explosive than previously thought
A recent study published in the journal Nature Communications found that benign volcanoes that produce basaltic lava flows hide highly explosive magma components. Many volcanoes do not cause life-threatening eruptions even though they release a steady stream of lava. For example, volcanoes in Iceland, Hawaii and the Galapagos Islands consistently emit lava comprised of molten basaltic rock. […]

Carbon dioxide may be the key to unlocking vast natural gas resources, research says
Carbon dioxide may be used to help produce natural gas from deposits buried deep beneath the Earth. A recent study is proposing that air and carbon dioxide injected into methane ice deposits that are buried beneath the Gulf of Mexico could unlock vast natural energy resources. Researchers from the University of Texas at Austin (UT Austin) […]

A dead supercontinent is partly responsible for the ocean sinking into the Earth’s mantle, explain researchers
Every day, hundreds of millions of gallons of water drain from the oceans into the Earth’s mantle, and geologists think that a dead supercontinent may be to blame. Dubbed the “deep water cycle” or the “geologic water cycle,” this phenomenon occurs when water gets soaked up by minerals within the earth’s mantle through a process called subduction. As the […]

Aging power plants under threat from droughts
Thermoelectric power plants provide a third of America’s electrical generation, and the combination of aging technologies, droughts, and strict environmental regulations is likely to sharply reduce the energy output. To prevent this, researchers recommend replacing the once-through cooling systems of the aging power plants with drought-resistant recirculating models. Their study countered the calls by some groups […]

Single-use no more: Plastic bottles can be upcycled to more durable materials
Single-use plastics cause plastic pollution, a problem that affects rivers, lakes, and oceans. To address this concern, researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a recycling process that turns various materials made of polyethylene terephthalate (PET) into other useful products that will last longer. NREL’s research was published in the journal Joule. What is […]

Grow your own cup: Biodegradable cups made from gourds may end single-use coffee cups
A New York-based design company called Creme is doing its part to reduce the amount of plastic trash churned out each year. Instead of manufacturing disposable coffee cups with plastic liners, the start-up grows biodegradable, organic containers from fruits. For their project, Creme picked gourds from the Cucurbitaceae family. Related to squash and pumpkins, these […]

Scientists synthesize eco-friendly lubricant oils from sustainable, organic waste
Lubricants are a key ingredient in making sure modern technology runs smoothly. It’s used in cars, home appliances, and industrial machinery – pretty much everything that has an engine. But while they’re helpful, mineral oil can heavily pollute the environment. The most common alternative, synthetic base oil, is unlikely to completely replace mineral oil due […]

Floating a new idea to conserve space: Solar panels are now being installed on floating water rafts
In 2008, a winery in Napa Valley, California set up the first floating solar array in the world. The idea of floating solar panels became popular in Asia, but it only gained traction in the U. S. in recent years. Experts believe that floating solar arrays on artificial bodies of water might produce more than 400 gigawatts of […]

What will it take for green energy to overtake fossil fuels as our main source of power?
Japanese researchers from three prestigious academic institutions took a hard look at the kind of technology needed by the hydrogen-based green energy industry to successfully compete with the fossil fuel energy industry. They estimated that Japan needs a new generation of cheap rechargeable batteries to produce clean, renewable fuel at cost-effective rates. Aside from the technology levels, the joint study also considered the economic […]
