Decarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4 issue of the journal Science suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
Power plants generate electricity and send it into power lines that distribute energy to nodes where it can be used. But if the electricity load is more than the system’s capacity, transmission can fail, leading to a cascade of failures throughout the electric grid. In the journal Chaos, researchers show demand side control may be an effective solution to stabilizing the reliability of power grids that use a mix of energy generation sources.
Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible energy storage. Research reported in Applied Physics Reviews aims to offer a solution by showing how the inclusion of conductive fillers improves battery performance.
A new interdisciplinary Cornell University research project is designed to unlock the power of wind energy by optimizing the spacing between wind turbines and wind turbine arrays to maximize power production.
Engineers have invented a way to spray extremely thin wires made of a plant-based material that could be used in N95 mask filters, devices that harvest energy for electricity, and potentially the creation of human organs. The method involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging from electronics to plants, according to a Rutgers-led study in the journal Materials Horizons.
Ning Zhou from Binghamton University, State University of New York received a National Science Foundation (NSF) CAREER Award to provide a 21st-century vision for power systems.
Irvine, Calif., Aug. 18, 2020 – Cyber-physical systems security researchers at the University of California, Irvine can disrupt the functioning of a power grid using about $50 worth of equipment tucked inside a disposable coffee cup. In a presentation delivered at the recent Usenix Security 2020 conference, Mohammad Al Faruque, UCI associate professor of electrical engineering & computer science, and his team revealed that the spoofing mechanism can generate a 32 percent change in output voltage, a 200 percent increase in low-frequency harmonics power and a 250 percent boost in real power from a solar inverter.
As the climate of the planet is changing, many researchers are looking to more renewable energy sources. In the Journal of Sustainable and Renewable Energy, researchers investigate whether the power generated by solar and wind farms would differ between current and future climates. The researchers focused on sites in Australia where variable renewable generators are located or are likely to be located in the future based on the Australian Energy Market Operator’s system plan.
Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.
Oak Ridge National Laboratory researchers have developed an intelligent power electronic inverter platform that can connect locally sited energy resources such as solar panels, energy storage and electric vehicles and smoothly interact with the utility power grid.
Utility-scale photovoltaics are the largest sector of the overall solar market within the U.S. and the fastest-growing form of renewable power generation, and this fleet of utility-scale photovoltaic projects is relatively young and hasn’t been operating long enough to establish a lengthy history of operational field service. In the Journal of Renewable and Sustainable Energy, researchers assess the performance of 411 utility-scale photovoltaic projects built within the U.S. from 2007 through 2016.
Using electronic devices for too long can cause them to overheat. Now, researchers reporting in ACS’ Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into electricity.
What do energy usage in buildings and traffic congestion have in common? Crowdsourcing.
New Brunswick, N.J. (April 13, 2020) – Rutgers University–New Brunswick experts are available for interviews on the impacts of the COVID-19 pandemic on greenhouse gas emissions, climate change and efforts to promote a greener economy and lifestyles. “During the 2007…
As we look back at a decade of discovery, we highlight 10 achievements by scientists at Berkeley Lab and the Joint Center for Artificial Photosynthesis that bring us closer to a solar fuels future.
A small amount of electricity delivered at a specific frequency to a particular point in the brain will snap a monkey out of even deep anesthesia, pointing to a circuit of brain activity key to consciousness and suggesting potential treatments for debilitating brain disorders.
The U.S. Department of Energy (DOE) has awarded nearly $1 million to a research team led by Missouri University of Science and Technology to study ways to better harness the power of water as an energy source. About 10% of electricity in the U.S. is created by moving water, or hydropower, according to the DOE’s Hydropower Vision report, which also found great potential in improving hydropower systems to meet more U.
While LED lighting can enhance plant growth in greenhouses, standards are needed to determine the optimal intensity and colors of light, according to Rutgers research that could help improve the energy efficiency of horticultural lighting products.
Scientists studied how the bacteria transport electrons across their cell wall. The bacteria use a method that’s different from other, known electricity-producing bacteria. They also found that hundreds of other bacterial species use this same process.

By increasing conductivity 10-fold, the engineers can reduce energy use, extend the life of devices and increase their performance.
Cornell and Northwestern University engineers, along with a federal economist, have created an energy model that helps to remove carbon-generated power from the U.S. electric grid – replacing it with a greener, financially feasible wind, solar and hydro energy system.
When two mesh screens are overlaid, beautiful patterns appear when one screen is offset. These “moiré patterns” have long intrigued artists, scientists and mathematicians and have found applications in printing, fashion and banknotes. Now, a Rutgers-led team has paved the way to solving one of the most enduring mysteries in materials physics by discovering a moiré pattern in graphene, where electrons organize themselves into stripes, like soldiers in formation.
