  • An (Even More) Inconvenient Truth: Why Carbon Credits For Forest Preservation May Be Worse Than Nothing

    This story examines the well-publicized climate-change strategy of carbon credits: the idea that a CO₂-emitting company could offset its emissions by funding anti-logging efforts, effectively "saving" the equivalent amount of carbon. However, as it turns out, despite its popularity, most carbon credit programs do not actually work or, worse, may do more harm than good. This article details the shortcomings of this attempted solution to the effects of global warming.

  • Termite and ventilation system

    Buildings with permeable surfaces increase energy efficiency, mimicking natural structures. In Harare, Zimbabwe, the Eastgate Centre employs methods borrowed from termite mound construction to efficiently regulate the building's temperature. By employing insights that scientists had gained by studying the airflow in termite mounds, the Centre’s architects used materials with a high thermal mass, increased surface area, and maximized ventilation.

  • Lessons Learned From California's Pioneering Microgrids

    Years after the California Energy Commission funded and launched demonstration microgrids, they’re seeing results. These microgrids, which are localized energy sources that can work independently from large electric grids, were fairly costly, but have shown demonstrable success in lowering utility bills and delivering low-carbon power. As the Commission moves forward with this effort, they hope to continue to learn by doing and improving their processes.

  • Militaries go green, rethink operations in face of climate change

    As climate change intensifies, militaries around the world have start adopting new equipment, practices, and processes. The United States has developed the International Military Council on Climate and Security, intended to better understand how the effects of climate change can and do fuel conflict. Globally, NATO members are testing new equipment, like diesel-solar powered systems, to increase their efficiency and reduce their fuel consumption.

  • Biogas saves money at wastewater treatment plant

    Turning sewage sludge into usable biogas helps make wastewater treatment more efficient. A water treatment plant in the city of Medina, Ohio, produces net energy from sludge. The plant uses anaerobic bacteria and a thermal hydrolysis process to convert wastewater and sludge into usable byproducts, like biogas.
