Biodiversity is an extremely important component of the Earth System that is both difficult to quantify and vital to understand. In a recent special issue of Remote Sensing, several articles describe the progress we have made in quantifying various aspects of biodiversity using novel imaging...

Either organic substances or the salt content of water could be turned into energy, with the help of membranes. This review paper presents several state-of-the-art membrane technologies: pressure-retarded osmosis and reverse electrodialysis, as well as microbial fuel-cell technology, all of which...

While generally more costly to manufacture than silicon, compound semiconductors (usually composed of elements from columns three and five of the periodic table) offer superior performance when fabricated into solar cells. One of the methods of reducing the cost of these more expensive materials is...

Capturing CO2 and storing it underground has been proposed to be a major player in mitigating global climate change by reducing CO2 emission. Thermal power plants, being the largest point source of CO2 emission, naturally become the primary target of CO2 capture and storage (CCS). However, it is...

Earth’s climate system includes several patterns of climate variability at the hemispheric scale. One of the best known of these is the El-Nino/Southern Oscillation, which influences weather across much of the globe. Another important feature of the climate system is the Southern Annular Mode...

The vast majority of commercially available solar panels available today are heavy, stiff, and only 10-15% efficient at converting incident sunlight to electric power. A start-up company called Alta Devices based in Santa Clara, California aims to dramatically change this norm by replacing the...

The concept of utilizing wastes as new resources promises us a sustainable development. However, is this concept applicable in reducing CO2 emission by turning it into useful products? Maybe not. Authors from the Electric Power Research Institute present two challenges of CO2 capture: the massive...
