    Save the Planet & Money with Heat Pumps

    Super high-efficiency electric heat pumps have become very common in all parts of the world for water heating, space heating, and air conditioning. They can operate in even the coldest climates and deliver the same heating and cooling benefits, often at lower operating costs. In addition, heat pumps powered by renewable energy produce zero emissions! Heat pumps are super-efficient because they use very little energy to move heat. Heat pumps have been used for decades to transfer heat out of your refrigerator to keep it cold on the inside and for air conditioning systems to cool your house. The same technology can now heat and cool your home or heat…

    Alternatives Exist for Rare Minerals in Batteries

    Greener, Friendlier Alternatives Exist for Rare Minerals in Batteries The Myth For years, commentators have been handwringing about the extraction practices, environmental and social harms, and corporate ownership of mining operations that contribute to clean energy technology, with a focus on cobalt, rare earths, and other rare ingredients of the clean energy transition. Much like governmental, intergovernmental, and private assessments of “critical materials,” these critiques pay far too little attention to how scarcity, usually signaled by price, elicits not only mineral exploration and mine development but also a powerful set of other and faster adaptations and alternatives like efficient use, substitution, and recycling. A major contribution to this genre comes from…

    Bat Fatalities at Wind Turbines

    Investigating the Causes & Consequences Wind energy is one of the fastest-growing industries in the world It represents an important step toward reducing dependence on nonrenewable sources of power. However, widespread deployment of industrial wind turbines has unprecedented adverse effects on certain species of bats that roost in trees and migrate. Bats are beneficial consumers of agricultural insect pests, and migratory species of bats provide free pest-suppression services across ecosystems and international borders. Although the underlying causes of bat fatalities at wind turbines remain unknown, potential clues can be found in the patterns of fatalities. TSH scientists, in collaboration with other U.S. Geological Survey (USGS) science centers as well as…

    Beneath Solar Panels, Seeds of Opportunity

    By 2030, utility-scale solar installations could cover almost 2 million acres of land in the United States. Traditional solar development would monopolize this land for just one use: energy production. Low-impact solar development, on the other hand, might also improve soil health, retain water, nurture native species, produce food, and provide even lower-cost energy to local communities. On a humid, overcast day in central Minnesota, a dozen researchers crouch in the grass between rows of photovoltaic (PV) solar panels. Only their bright yellow hard hats are clearly visible above the tall, nearly overgrown prairie grasses—which are growing exactly as expected. Bent over white, square frames, some of the researchers catalog…
