Passive solar could furnish a third of home heating needs

Passive solar heating systems collect natural light via skylights or windows and use it to directly heat spaces, without converting it to electricity. Based on a detailed analysis of heating needs and solar energy availability around the United States, such installations could supply a third of residential space heating needs nationwide, researchers found. The findings, which appear in the November issue of Renewable and Sustainable Energy Reviews, are the first detailed survey of direct solar heating resources in the U.S.

Wind and solar could power the world’s major countries most of the time

With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources. A recent study led by researchers at the University of California, Irvine tackles the reliability question head-on.

Synthetic Tree Enhances Solar Steam Generation for Harvesting Drinking Water

Solar steam generation has emerged as a promising renewable energy technology for water harvesting, desalination, and purification that could benefit people who need it most in remote communities, disaster-relief areas, and developing nations. In Applied Physics Letters, researchers inspired by mangrove trees thriving along coastlines developed a synthetic tree to enhance SSG, replacing capillary action with transpiration, the process of water movement through a plant and its evaporation from leaves, stems, and flowers.

Researchers unveil roadmap to expand NY solar energy, meet green goals

Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York’s green energy goals, according to forthcoming Cornell University research.

MTU Experts in Snow, Solar, and Power Outages

Michigan Technological University resides in the Keweenaw, a part of Michigan’s Upper Peninsula that gets more than 200 inches of snow every winter. Michigan Tech researchers—engineers, sociologists, computer scientists—study renewable energy grids, their strengths and weaknesses, community resilience and impact…

Dr. Thomas Rimmele, Director of NSF’s Inouye Solar Telescope, Named One of Fast Company’s Most Creative People in Business

Dr. Thomas Rimmele from the National Science Foundation’s (NSF) National Solar Observatory joins the 11th annual list of awardees from such companies as Netflix, Google, and Patagonia, as well as institutions such as Johns Hopkins University and the ACLU of Massachusetts.

Geoengineering is Just a Partial Solution to Fight Climate Change

Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.

Geoengineering’s Benefits Limited for Apple Crops in India

Geoengineering – spraying sulfur dioxide into the atmosphere to combat global warming – would only temporarily and partially benefit apple production in northern India, according to a Rutgers co-authored study. But abruptly ending geoengineering might lead to total crop failure faster than if geoengineering were not done, according to the study – believed to be the first of its kind – in the journal Climatic Change.

NSF’s Newest Solar Telescope Produces First Images

Just released first images from the National Science Foundation’s Daniel K. Inouye Solar Telescope reveal unprecedented detail of the Sun’s surface and preview the world-class products to come from this preeminent 4-meter solar telescope. NSF’s Inouye Solar Telescope, on the summit of Haleakala, Maui, in Hawai‘i, will enable a new era of solar science and a leap forward in understanding the Sun and its impacts on our planet.

Which Climates Are Best for Passive Cooling Technologies?

If you guessed locations with drier atmospheres and frequent clear skies, you’re right. WASHINGTON, D.C., June 25, 2019 — A group of University of California­, San Diego researchers set out to gain a better understanding of the thermal balance of…
