Chemistry with sunlight: Combining electrochemistry and photovoltaics to clean up oxidation reactions
Researchers can make the oxidation reactions used in the synthesis of organic molecules cleaner by hitching photovoltaics to electrochemistry. The idea is simple and yet it has huge implications. To underscore the simplicity of the idea, researchers used a $6 solar cell sold on the Internet and intended to power toy cars to run a variety of chemical reactions. If their suggestion were widely adopted by the chemical industry, it would eliminate the toxic byproducts currently produced by a class of reactions commonly used in chemical synthesis -- and with them the environmental and economic damage they cause.

A new report from China touts the benefits of solar greenhouses as having the potential to solve the world's energy crisis and climate change. The research study of China's single-slope solar greenhouses provides important recommendations for agricultural operations in China and countries such as Japan, Korea, and Russia, where the designs have been successfully adopted. The researchers discuss the challenges of solar dependence in winter and recommend strategies for sustaining the development of solar structures.

Scientists have claimed one of the milestones in the drive for sustainable energy -- development of the first practical artificial leaf. Researchers have developed an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.

When combined with on-Oahu wind farms and solar energy, the Interisland Wind project planned to bring 400 megawatts (MW) of wind power from Molokai and Lanai to Oahu could reliably supply more than 25 percent of Oahu's projected electricity demand, according to a new study.
