Wind power is an increasingly popular form of renewable energy. However, when it’s time to replace the huge turbine blades that convert wind into electricity, disposal is a problem. Now, scientists report a new composite resin suitable for making these behemoths that could later be recycled into new turbine blades or a variety of other …

Wind energy continues to see strong growth, solid performance, and attractive prices in the U.S., according to a report released by the U.S. Department of Energy (DOE) and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). With levelized costs of just over $30 per megawatt-hour (MWh) for newly built projects, the cost of wind is …

Researchers have developed floating ‘artificial leaves’ that generate clean fuels from sunlight and water, and could eventually operate on a large scale at sea. The researchers, from the University of Cambridge, designed ultra-thin, flexible devices, which take their inspiration from photosynthesis — the process by which plants convert sunlight into food. Since the low-cost, autonomous …

Decarbonisation scenarios produced by BP, Royal Dutch Shell and Equinor are incompatible with Paris Agreement goals for a safe and habitable planet. This is the finding of new research underscoring how global decarbonisation scenarios outlined by these energy companies show delayed reductions in fossil fuel consumption and run the risk of overshooting vital climate goals. …

Virtually all wind turbines, which produce more than 5 percent of the world’s electricity, are controlled as if they were individual, free-standing units. In fact, the vast majority are part of larger wind farm installations involving dozens or even hundreds of turbines, whose wakes can affect each other. Now, engineers at MIT and elsewhere have …

Solar panels aren’t just for rooftops anymore — some buildings even have these power-generating structures all over their facades. But as more buildings and public spaces incorporate photovoltaic technologies, their monotonous black color could leave onlookers underwhelmed. Now, researchers reporting in ACS Nano have created solar panels that take on colorful hues while producing energy …

The DGIST (President Kuk Yang) Thin Film Solar Cell Research Center (Chairman Gang Jin-gyu) worked with Professor Kim Se-yoon of the Department of New Material Engineering at Kyungnam University (President Park Jae-gyu) to investigate the cause of pore formation, a problem in CZTS thin-film solar cells, which are eco-friendly general-purpose thin-film solar cells.  “Solar cells,” …

A new control algorithm for wind farms that alters how individual turbines are oriented into the wind promises to boost farms’ overall efficiency and energy output by optimizing how they deal with their turbulent wake. The algorithm, which was tested at a commercial wind farm in India but could be employed anywhere, offers the potential …

Researchers from the University of Technology Sydney (UTS) and Queensland University of Technology (QUT) have developed a new method to improve solid-state hydrogen fuel cell charging times. Hydrogen is gaining significant attention as an efficient way to store ‘green energy’ from renewables such as wind and solar. Compressed gas is the most common form of …

Engineers have designed and successfully tested a more efficient wind sensor for use on drones, balloons and other autonomous aircraft. These wind sensors — called anemometers — are used to monitor wind speed and direction. As demand for autonomous aircraft increases, better wind sensors are needed to make it easier for these vehicles to both …

Scientists evaluate how to make ammonia production more sustainable. Ever wondered about the carbon impact of growing your dinner? Scientists have just come up with a new way to calculate part of it. A major ingredient in the production of fertilizers for the world’s food production, ammonia also contributes significantly to the world’s greenhouse gas …

Scientists have created a novel technology that can help to tackle climate change. Northumbria University’s Dr Shafeer Kalathil is among a team of academics behind the project, which uses a chemical process that converts sunlight, water and carbon dioxide into acetate and oxygen to produce high-value fuels and chemicals powered by renewable energy. As part …

1.5 degrees, 2 degrees or more? The Paris Agreement and the climate ambition of a carbon-neutral EU in 2050 have been put back by the war in Ukraine. Or have they? New research from Aarhus University shows that the very high gas prices currently experienced by the Eurozone are a very efficient driver for the …

As policymakers around the world aim to cut carbon emissions and meet climate goals, new research points to a critical group whose opinions could help to shape energy planning for the better: the consumers. By taking into account the demographics and preferences of US racial groups, clarified through a nationally representative survey of 3,000 US …

Researchers have designed a fuel production system that uses water, carbon dioxide (CO2), and sunlight to produce aviation fuel. They have implemented the system in the field, and the design, publishing July 20 in the journal Joule, could help the aviation industry become carbon neutral. “We are the first to demonstrate the entire thermochemical process …

Air pollution remains a silent killer in Massachusetts, responsible for an estimated 2,780 deaths a year and for measurable cognitive loss in Bay State children exposed to fine particulate pollutants in the air they breathe, according to a new study by researchers at Boston College’s Global Observatory on Planetary Health. The study was supported by …

Passive day cooling is a promising technology for the sustainable reduction of energy consumption. It avoids the heating up of buildings by solar radiation and dissipates accumulated heat without external energy consumption. Researchers at the University of Bayreuth have now created a test system with which the materials used for passive cooling can be reliably …

The study was headed by Professor Claudia Kemfert from the German Institute for Economic Research (DIW) and Leuphana University Lüneburg in collaboration with Franziska Hoffart from Ruhr-Universität Bochum, Fabian Präger from Technische Universität Berlin and Isabell Braunger and Hanna Brauers from the University of Flensburg. Energy crisis is only one facet of the problem In …

With energy costs rising, and the rapidly emerging effects of burning fossil fuels on the global climate, the need has never been greater for researchers to find paths to products and fuels that are truly renewable. “We use 20 million barrels of oil a day in the U.S.; that’s about a fifth of the world’s …
