Unused stockpiles of nuclear waste could be more useful than we might think
10 Jan 2020 at 7:10am
Chemists have found a new use for the waste product of nuclear power -- transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources.
Tests measure solar panel performance beyond established standards
2 Jan 2020 at 3:48pm
In testing solar panels, the sun's intensity, the spectral composition and the angle of light are important factors in understanding why certain panels are successful and others degrade more quickly. To address the knowledge gap in degradation mechanisms for various photovoltaic types, researchers performed tests over five years in which they collected weather data and panel performance information.
Could every country have a Green New Deal? Report charts paths for 143 countries
20 Dec 2019 at 12:05pm
Researchers offer an updated vision of the steps that 143 countries around the world can take to attain 100% clean, renewable energy by the year 2050. The new roadmaps project that transitioning to clean, renewable energy could reduce worldwide energy needs by 57%, create 28.6 million more jobs than are lost, and reduce energy, health, and climate costs by 91% compared with a business-as-usual analysis.
Consider marine life when implementing offshore renewable power
17 Dec 2019 at 8:42am
With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life.
Big step in producing carbon-neutral fuel: Silver diphosphide
16 Dec 2019 at 9:24am
A new chemical process does in the lab what trees do in nature -- it converts carbon dioxide into usable chemicals or fuels.
Artificial intelligence may help scientists make spray-on solar cells
16 Dec 2019 at 9:24am
Artificial Intelligence may be just the thing to accelerate spray-on solar cell technology, which could revolutionize how consumers use energy. A research team has used Machine Learning, aka Artificial Intelligence to optimize the materials used to make perovskite solar cells (PSC). The Organic-Inorganic halide perovskites material used in PSC converts photovoltaic power into consumable energy.
Researchers perfect nanoscience tool for studies of nuclear waste storage
12 Dec 2019 at 11:19am
Studying radiation chemistry and electronic structure of materials at scales smaller than nanometers, scientists prepared samples of clay in ultra-thin layers. Working at the TRIUMF particle accelerator, they bombarded the samples with antimatter subatomic particles. They found their system is a proven tool for radiation studies of material to be used to store nuclear waste -- important for Canadian nuclear industry looking to build its first geological repository.
Supporting structures of wind turbines contribute to wind farm blockage effect
12 Dec 2019 at 7:46am
Much about the aerodynamic effects of larger wind farms remains poorly understood. New work looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.
Punching holes in opaque solar cells turns them transparent
11 Dec 2019 at 8:55am
Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching tiny holes on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to 'see' the pattern.
Scientists convert plastics into useful chemicals using sunlight
11 Dec 2019 at 7:03am
Chemists have discovered a method that could turn plastic waste into valuable chemicals by using sunlight.
New method to remove dust on solar panels
9 Dec 2019 at 5:05am
Particle removal increased from 41% on hydrophilic smooth Si wafers to 98% on superhydrophobic Si-based nanotextured surfaces. The researchers confirmed these results by measuring the adhesion of a micron-sized particle to the flat and nanotextured substrate using an atomic force microscope. They found that the adhesion in water is reduced by a factor of 30.
As China rapidly adopts clean energy, use of traditional stoves persists
5 Dec 2019 at 12:53pm
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.
Global carbon emissions growth slows, but hits record high
4 Dec 2019 at 6:08am
Coal use is down dramatically in the United States and the European Union, and renewable energy is gaining traction. But rising natural gas and oil use in 2019 increased the world's carbon dioxide emissions modestly for a third straight year.
Daylight damage to photovoltaics
2 Dec 2019 at 7:21am
A research team has investigated the ways sunlight can degrade the efficiency of newly developed organic photovoltaics over time. This work may assist in the wide commercialization of next-generation solar sheets.
Carbon intensity of power sector down in 2019
27 Nov 2019 at 1:13pm
Engineers have compiled carbon emissions for the US electric power sector for the second quarter (Q2) of 2019 as part of the CMU Power Sector Carbon Index.
