The US Department of Energy's National Renewable Energy Laboratory (NREL) has confirmed the technical and economic viability of integrating 175 gigawatts (GW) of renewable energy into India's grid by 2022.
With numerous installations of solar power systems for residential homes, there is a challenge to balance supply and demand to make these intermittent energy sources reliable. Demand response is one promising way to increase operational flexibility and energy efficiency, and researchers in Malaysia have incorporated scenarios in case studies based on 100 urban low-voltage network samples to learn more. They report their findings in this week's Journal of Renewable and Sustainable Energy.
Researchers have developed a new synthesis route for alternative catalysts of noble metals.
This article describes simulation of recycled neutral atoms on plasma turbulence in fusion experiments.
Washington State University researchers have developed a way to grow algae more efficiently -- in days instead of weeks -- and make the algae more viable for several industries, including biofuels.
Twenty years ago, microbiologist Barry Goodell, now a professor at UMass Amherst, and colleagues discovered a unique system that some microorganisms use to digest and recycle wood. Three orders of 'brown rot fungi' have now been identified that can break down biomass, but details of the mechanism were not known. Now, using several complementary research tools, Goodell and colleagues report new details of an unexpected mechanism at work, one that surprisingly does not involve enzymes, the usual accelerators of chemical reactions.
In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take in carbon dioxide and emit water through the pores in their leaves. The data boosted the accuracy of mathematical models of carbon and water fluxes through plant leaves by 30 to 60 percent.
Studies of naturally carbonated mineral water have given scientists insight on how to locate hot water springs -- potential sources of sustainable geothermal energy.
Scientists got a breakthrough in polycyclic aromatic compounds in the process of coal formation.
The international Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS) collaboration based at the University of California, Riverside has combined observations from several of the world's most powerful telescopes to carry out one of the largest studies yet of molecular gas -- the raw material which fuels star formation throughout the universe -- in three of the most distant clusters of galaxies ever found, detected as they appeared when the universe was only four billion years old.
