The Thai village using poop to power homes

Nestled in a deep pocket of forest that lies off Thailand's electrical grid, villagers in Pa Deng have become early adopters and evangelists for an unusual alternative energy source: poop.

Modeling sunlight harvesting in nanostructures

To create the next generation of solar panels and other light-driven devices, scientists must model how complex interactions occur. Modeling across different scales, from individual atoms to very large systems with thousands ...

Feeling smug about your solar rooftop? Not so fast

If you installed solar panels on your roof and feel aglow with environmental virtue, you may be in for a rude awakening. There's a good chance someone else has purchased your halo and is wearing it right now.

Enlisting distributed energy devices to balance the power grid

The electric grid has to balance power supply and demand nearly in real-time, requiring power plants to be adjusted on a second-by-second basis. This instantaneous balance is made significantly more complex by renewable energy ...

Diagnosing better efficiencies for solar cells

A new diagnostic imaging technique developed by a University of Maryland -led team of researchers promises to boost efficiencies of solar cells by making it possible to find and correct previously undetected ways that solar ...
