May 17th 2011
As China's economy continues to soar, its energy use and greenhouse gas emissions will keep on soaring as well—or so goes the conventional wisdom. A new analysis by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) now is challenging that notion, one widely held in both the United States and China.

Buildings are responsible for a large fraction of total U.S. energy demand and buildings are replaced slowly. About one third of the U.S. population lives in multifamily buildings. The residents of multifamily buildings often have below-average incomes and they are sometimes exposed to high levels of potentially harmful indoor contaminants. The U.S. is embarking on a program of aggressive energy retrofits in homes, with a substantial focus on... Read More

The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit—greenhouse gases, such as carbon dioxide—from other particles in the air that may be causing the melting. Menon and her collaborators found that airborne... Read More
