chemical: A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom. Its chemical formula is H2O. Chemical also can be an adjective to describe properties of materials that are the result of various reactions between different compounds. family: A taxonomic group consisting of at least one genus of organisms. forage: To search for something, especially food.

A hexagon-shaped atmospheric phenomenon first spotted on Saturn by Voyager 1 and Voyager 2 has intrigued scientists since the 1980s. More recently, NASA's Cassini mission has periodically observed the hexagon and its embedded strong eastward jet that rotates at 120 meters per second. Scientists believe that the persistence of the hexagon could put to rest the oft-debated question of the length of Saturn's rotational period.

ancestor: A predecessor. It could be a family forebear, such as a parent, grandparent or great-great-great grandparent. Or it could be a species, genus, family or other order of organisms from which some later one evolved. For instance, ancient dinosaurs are the ancestors of today's birds. (antonym: descendant)ape: A group of rather large primates, all of which lack a tail. They include gorillas, chimpanzees, bonobos, orangutans, gibbons and humans.

An electric vehicle manufacturer, two schools and two Alaskan villages: these are just some of the organizations using wind turbines to help meet their energy needs. For the last eight months, researchers from the Department of Energy's Pacific Northwest National Laboratory have been scouring the nation for information about who installed distributed wind energy projects.

If all the high-voltage transmission currently under construction and in advanced stages of permitting is built by 2030 in the Western United States—enabling the construction of new renewable energy projects—carbon dioxide emissions in the Western United States would drop by 73% compared to 2005. Energy generation costs would also decrease 32% by 2030, compared to a reference case where most of these projects are not built.

ENERGY SECURITYHydropower Generation Projected to Rise, but Climate Change Brings Uncertain FuturePublished 3 September 2024A new analysis combines hydrology data with climate change models to help water managers prepare for hydropower’s future. In a new study assessing how climate change might alter hydropower generation across the continental United States, researchers show that except for some parts of the Southwest, hydropower generation is expected to rise in the future.

In a new study assessing how climate change might alter hydropower generation across the continental United States, researchers show that except for some parts of the Southwest, hydropower generation is expected to rise in the future. The analysis also shows that in the Pacific Northwest in the future, less water will be stored in the mountains as snowpack in the winter as warmer temperatures bring more rain.
