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.
