Solar Cell Advances: Omitting Lead from Promising Cell

Environmentally friendly solar cell advances push forward the ‘next big thing in photovoltaics’ Solar cell electronics appear to be getting friendlier on the environmental side of the spectrum. Northwestern University researchers have developed a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. This research advance provides a low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry — no fancy equipment or hazardous materials. “This is a breakthrough…

Guest Post: The Trend of Sustainability & Businesses Creating an Impact

I would like to thank Kenny Myers for this guest contribution about the trend toward sustainability. – GM According to some so-called experts, green building and sustainable technologies are nothing more than a fad and fossil fuels will undoubtedly make a return. However, it’s hard to believe that rhetoric when so many businesses and homeowners are taking part in creating an energy conscious connection. In April of 2014, Marriott International, Inc. announced that it has created its first LEED certified hotel…

Bacardi Enhances The Efficiency Of Its Rum Facility

Bacardi, a wine company based in Puerto Rico, has been building its reputation for sustainability since 2006. Last year, it announced that it significantly reduced its water and energy usage. It is now taking the next step towards sustainability with the installation of solar skylights, which are intelligently designed ‘windows’ that allow plenty of sunlight into the rum warehouse, helping to keep it warm and nicely lit during winter, reducing heating demand, and the need for electric lighting. In addition to…

Biofuels from Corn Residue Show Negative Climate Impacts

The environmental price for producing biofuels like ethanol from corn residue is significant. Sad to report research from a University of Lincoln team reports that this kind of biofuel could generate more greenhouse gas than does gasoline. I have never been an ethanol enthusiast anyway. Read the following release. Study casts doubt on climate benefit of biofuels from corn residue Lincoln, Neb., April 20, 2014 — Using corn crop residue to make ethanol and other biofuels reduces soil carbon and…
