LED lamps: less energy, more light

LEDs are durable and save energy. Now researchers have found a way to make LED lamps even more compact while supplying more light than commercially available models. The key to success: transistors made of the semiconductor material gallium nitride.

Manufacturing a solution to planet-clogging plastics

Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects - from cell phones to food containers and toys - using a fully degradable bioplastic isolated from shrimp shells. The objects exhibit many of the same properties as those created with synthetic plastics, but without the environmental threat.

NREL examines solar policy pathways for states

The Energy Department's National Renewable Energy Laboratory (NREL) has published a report that aligns solar policy and market success with state demographics. By organizing the 48 contiguous states into four peer groups based on shared non-policy characteristics, the NREL research team was able to contextualize the impact of various solar policies on photovoltaic installations.

Advancing algae's viability as a biofuel

Lab success doesn't always translate to real-world success. A team of Michigan State University scientists, however, has invented a new technology that increases the odds of helping algae-based biofuels cross that gap and come closer to reality.

Climate engineering: Minor potential, major side effects

Researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel have studied with computer simulations the long-term global consequences of several 'climate engineering' methods. They show that all the proposed methods would either be unable to significantly reduce global warming if CO2 emissions remain high, or they could not be stopped without causing dangerous climate disruption.

Now it will become cheaper to make second-generation biofuel for our cars

Producing second-generation biofuel from dead plant tissue is environmentally friendly -- but it is also expensive because the process, as used today, needs expensive enzymes, and large companies dominate this market. Now a Danish/Iraqi collaboration presents a new technique that avoids the expensive enzymes. The production of second generation biofuels thus becomes cheaper, probably attracting many more producers and competition, and this may finally bring the price down.

Pond-dwelling powerhouse's genome points to its biofuel potential

Duckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant's potential as a biofuel source a big boost.
