Accounting for Greenhouse Gases: Methane in India

How do we know how much heat-trapping greenhouse gas there is in the atmosphere? What about where these greenhouse gases are coming from? Scientists work hard to answer these questions on global, national, and regional levels. Recently, a group of scientists from India, the United Kingdom, Germany, and the United States collaborated to evaluate India’s emissions of the greenhouse gas methane. This blog post explains how greenhouse gas accounting is similar to tracking your bank account. The post then discusses in more detail how the India study was conducted, and why its findings are important.

Generating electricity while microbes clean wastewater – how wastewater treatment plants could go from brown to green

Microbial fuel cells are structures that behave like batteries, but are powered by ever-present environmental microbes. Researchers in South Korea measured the ability of Microbial Fuel Cell prototypes to generate electricity while cleaning up wastewater. Results indicate that this technology could radically reduce the energy requirements of wastewater treatment facilities.
