UChicago-Argonne National Lab Team Improves Solar Cell Efficiency

Great research on solar cell efficiency improvements continues to be reported, this time from scientists in the University of Chicago’s chemistry department, the Institute for Molecular Engineering, and Argonne National Laboratory. We offer our highest praise to support the evolution of the renewable energy industry, which in turn, will boost better products for green building. New light has been shed on solar power generation using devices made with polymers, thanks to a collaboration between scientists in the University of Chicago’s chemistry…

Worldwide Water in 2050: Reducing Scarcity is Possible

With the possibility of a worldwide water shortage facing future generations, this paper concerning strategies which might mitigate some of the problems has been published in Nature Geoscience. Take a look. Increased water-recycling and improved irrigation techniques among six strategies identified as key to successfully reducing global water scarcity Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last…

Coal’s Dominance & Carbon Emissions Must Be Made More Apparent in Climate Change Accounting

The world’s accounting system for carbon emissions, run by the United Nations, disregards capital investments in future coal-fired and natural-gas power plants that will commit the world to several decades and billions of tons of greenhouse gas emissions, according to a new study from Princeton University and the University of California-Irvine published Aug. 26 in the journalEnvironmental Research Letters. In the paper, Robert Socolow, a Princeton professor, emeritus, of mechanical and aerospace engineering, and co-author Steven Davis, a professor of…

Water and Sunlight the Formula for Sustainable Fuel

This news on water and sunlight  from Australian National University is worth reading. An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel. “Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and do it cheaply and safely,” said Dr Kastoori Hingorani, from the ARC Centre of Excellence for…

Guest Post: New Tools for Improving Energy Efficiency at Universities

Any time we hear about improving energy efficiency we get excited. Read this guest post from Danielle Kershner, with contributing help from Keri Masterson.  Intelligent buildings can now match the demands of multi-faceted institutions By Danielle Kershner of Eco Brandit Reducing energy consumption to save money is a concept becoming increasingly important. But how are we identifying these savings, and is there a way to maximize the potential for savings opportunities? Intelligent efficiency defines the next generation of efficiency methods…

Plastics Advances: CO2 Sponge Could Reduce Fossil Fuel Emissions

This presentation pertaining to a CO2 sponge is one of some 12,000 at the 248th National Meeting & Exposition of the American Chemical Society (ACS). If any part of this comes to a greater reality in mitigating climate change, this one particularly piques our interest. Read this press announcement from AAAS EurekAlert. A sponge-like plastic that sops up the greenhouse gas carbon dioxide (CO2) might ease our transition away from polluting fossil fuels and toward new energy sources, such as…
