Too much sun and too much heat can reduce the efficiency of photovoltaics. A solar farm with optimally spaced panels facing the correct direction could cool itself through convection using the surrounding wind. Researchers explored how to exploit the geometry of solar farms to enhance natural cooling mechanisms.
Renewable energy sources now represent 20% of the electricity generated in America. The proposed infrastructure bill seeks to expand renewables, but doesn’t outline how it will happen.
Computer simulations can help us understand interactions in materials for solar energy harvesting, but they can be extremely complex. Researchers at Argonne have simplified these modeling tasks using machine learning to speed up materials development.
The Engineering Division of the Council on Undergraduate Research announces the 2021 recipients of its Mentoring Awards and winners of its Student Video Competition.
Argonne scientists led four other laboratories in developing definitive guidance on how to value pumped storage hydropower projects. Their efforts resulted in DOE publication of the Pumped Storage Hydropower Valuation Guidebook: A Cost-Benefit and Decision Analysis Valuation Framework. The guide provides an objective, transparent valuation methodology and helps measure both monetary and non-monetary value streams.
Biodiversity Research Institute announces the formation of its new environmental consulting services division—BRI Environmental offering a full suite of services for evaluating and permitting renewable energy development projects, infrastructure projects, marine installations, as well as residential and commercial development.
Americans used approximately 7 percent less energy in 2020, due in part to the COVID-19 pandemic, according to energy flow charts released by Lawrence Livermore National Laboratory (LLNL).
Sandia National Laboratories has spent 10 years working alongside local company Guardian Sensors Inc. to understand and characterize hazardous arc-faults. Their work led to development of electrical in-line connectors that automatically predict and prevent photovoltaic arc-faults before they can ignite fires.
The National Science Foundation has awarded $39 million to a team of engineers and computer scientists at the University of California San Diego to build a first-of-its-kind testbed to better understand how to integrate distributed energy sources such as solar panels, wind turbines, smart buildings and electric vehicle batteries into the power grid. The goal is to make the testbed available to outside research teams and industry by 2025.
Scientists combined solar cell technology with a novel optimization approach to develop a smart window prototype that maximizes design across a wide range of criteria.
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.
Cloud cover is often characterized in simple terms, such as cloudy, partly cloudy or clear. This does not provide accurate information for estimating the amount of sunlight available for solar power plants. In this week’s Journal of Renewable and Sustainable Energy, a new method is reported for estimating cloud optical properties using data from recently launched satellites. This new technique is known as Spectral Cloud Optical Property Estimation, or SCOPE.
Low-carbon technologies that are smaller scale, more affordable, and can be mass deployed are more likely to enable a faster transition to net-zero emissions, according to a new study by an international team of researchers.
First-of-its-kind study systematically investigates the technical and economic feasibility of photovoltaics-powered energy self-sufficient households in a temperate climate
Distributed energy resources use electronics to communicate with each other or with a control center. Yet this presents opportunities for cyber attacks that could become real threats to the electric power system. Argonne experts are developing ways to protect power systems from these threats before they can occur.
Thanks to a generous gift from utility company Evergy, students in the College of Engineering at Wichita State University can learn about and conduct research on solar power technology, as well as how to protect an electric grid from short circuiting.
The Physical Chemistry Division of the American Chemical Society announces that Lin X. Chen has received the 2020 Award in Experimental Physical Chemistry. The award recognizes Chen for “fundamental contributions to the elucidation of excited state structures, dynamics and energetics of light harvesting systems.
