The U.S. should capitalize on China’s formidable experience to put its own domestic solar power sector on a more “economically sensible” path, researchers from Stanford University said in a new report. The March 21–released report, “The New Solar System,” which was funded by a research grant from the U.S. Department of Energy (DOE), offers a […]

The boom in renewable energy, spurred by dramatically falling costs, has led some experts and political figures to begin talking seriously about what was once science fiction: A world powered entirely by renewable generation. But is it truly feasible or economic? One series of studies suggests it is—with some important caveats. In the first half […]

Pairing energy storage with rooftop solar photovoltaic (PV) systems has been widely touted as the path for greater deployment of renewable energy, but a new study from researchers at the University of Texas suggests doing so may actually increase overall energy consumption and emissions. The study, “The Impacts of Storing Solar Energy in the Home […]
