Volkswagen presented at its ‘Power Day’ a planned future battery supply in Gigawatt Hours (GWh), as Tesla did the same half a year ago at its Battery Day in September in California. A day I had the honor to participate in. Gigawatt Hours of battery supply translates into Battery Electric Vehicles (BEV) and residential energy …

From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves. An international team of researchers, led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, has developed a …

In order to assess the risk of bats dying at wind turbines, it is common practice to record the acoustic activity of bats within the operating range of the rotor blades. For this purpose, ultrasonic detectors are attached to the nacelles of the mast top. In a recent analysis, a team of scientists led by …

Since the early industrial revolution in the mid-1700s, fossil fuels have acquired an ever-growing footprint in energy production. However, the environmental concerns of fossil fuels use and their inevitable depletion have led to a global shift toward renewable energy sources. These transitions, however, raise questions about the best choice of renewables and the impact of …

Given the finite nature of fossil fuel reserves and the devastating environmental impacts of relying on fossil fuels, the development of clean energy sources is among the most pressing challenges facing modern industrial civilization. Solar energy is an attractive clean energy option, but the widescale implementation of solar energy technologies will depend on the development …

One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers at Linköping University, Sweden, have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for hydrogen gas production. The study has been published in the journal ACS Nano. …

A recent study, affiliated with UNIST has unveiled a novel system, capable of producing hydrogen and electricity quickly and effectively while cutting carbon dioxide (CO2) emissions significantly. Published in the January 2021 issue of Nano Energy, this breakthrough has been carried out by Professor GunTae Kim and his research team in the School of Energy …

A recent study shows that lettuce can be grown in greenhouses that filter out wavelengths of light used to generate solar power, demonstrating the feasibility of using see-through solar panels in greenhouses to generate electricity. “We were a little surprised — there was no real reduction in plant growth or health,” says Heike Sederoff, co-corresponding …

A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade. “Our work paves the way for low-cost, high-throughput commercial-scale production of large-scale solar modules in the near future,” …

Hydrogen is a pollution-free energy source when it’s extracted from water using sunlight instead of fossil fuels. But current strategies for “splitting” or breaking apart water molecules with catalysts and light require the introduction of chemical additives to expedite the process. Now, researchers reporting in ACS ES&T Engineering have developed a catalyst that destroys medications …

Hydrogen is an incredibly powerful fuel, and the ingredients are everywhere — in plain old water. Researchers would love to be able to use it widely as a clean and sustainable energy source. One catch, however, is that a considerable amount of energy is required to split water and make hydrogen. Thus scientists have been …

As gatherings to observe whooping cranes join the ranks of online-only events this year, a new study offers insight into how the endangered bird is faring on a landscape increasingly dotted with wind turbines. The paper, published this week in Ecological Applications, reports that whooping cranes migrating through the U.S. Great Plains avoid “rest stop” …

Researchers studying the Swiss energy market have found that making green energy the default option for consumers leads to an enduring shift to renewables and thus has the potential to cut CO2 emissions by millions of tonnes. The study, published today in Nature Human Behaviour, investigated the effect of changes in the Swiss energy market …

The efficiency of solar cells can be increased by exploiting a phenomenon known as singlet fission. However, unexplained energy losses during the reaction have until now been a major problem. A research group led by scientists at Linköping University, Sweden, has discovered what happens during singlet fission and where the lost energy goes. The results …

Can Switzerland, as planned, cut its CO2 emissions to zero by 2050? In a study, researchers at the Paul Scherrer Institute PSI have investigated what measures would be necessary to achieve this reduction and how much it might cost per person. In August 2019, the Swiss Federal Council decided on an ambitious target to limit …

Hydrogen has been hailed as the ‘fuel of the future’ owing to several reasons. First, compared to the conventionally used hydrocarbons, hydrogen exhibits higher energy yield. Second, the commercial use of hydrogen fuel, which yields only water as a byproduct product, would help mitigate the imminent global warming crisis by reducing the use of exhaustible …

Putting a price on producing carbon is the cheapest, most efficient policy change legislators can make to reduce emissions that cause climate change, new research suggests. The case study, published recently in the journal Current Sustainable/Renewable Energy Reports, analyzed the costs and effects that a variety of policy changes would have on reducing carbon dioxide …

Wind turbine blades spinning through cold, wet conditions can collect ice nearly a foot thick on the yard-wide tips of their blades. That disrupts blade aerodynamics. That disrupts the balance of the entire turbine. And that can disrupt energy production by up to 80 percent, according to a recently published field study led by Hui …

Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution. Thus, many scientists worldwide have their hopes placed on what they regard as the fuel of tomorrow: …

Gill Nowell and Warren Phillips (EVA England) at Gridserve’s electric forecourt in Braintree, Essex I don’t get out much these days, but when I do, I like to leave home safe in the knowledge that my longer-than-usual car journey will be stress-free and smooth. The smooth part of the equation always works out for me …

The first observations of a space hurricane have been revealed in Earth’s upper atmosphere, confirming their existence and shedding new light on the relationship between planets and space. Hurricanes in the Earth’s low atmosphere are known, but they had never before been detected in the upper atmosphere. An international team of scientists led by Shandong …

The hidden social, environmental and health costs of the world’s energy and transport sectors is equal to more than a quarter of the globe’s entire economic output, new research from the University of Sussex Business School and Hanyang University reveals. According to analysis carried out by Professor Benjamin K. Sovacool and Professor Jinsoo Kim, the …
