Geomikrobiologen der Universität Tübingen klären Mechanismus der Nitratspeicherung bei der Kompostierung auf

Der übermäßige Einsatz von mineralischen Stickstoffdüngern oder Gülle in der Landwirtschaft hat schwerwiegende Auswirkungen auf unsere Umwelt. Dabei entstehen Treibhausgase wie zum Beispiel Lachgas, und das Grundwasser wird durch Nitrat belastet. Als umweltfreundliche Alternative wird diskutiert, Pflanzenkohle als Nährstoffträger in den Boden einzubringen. Allerdings lässt sie sich bisher nicht in großem Maßstab ökonomisch sinnvoll einsetzen, weil wenig darüber bekannt ist, wie Pflanzenkohle den wichtigen Nährstoff Nitrat speichert. (more…)

From Diablo Canyon on the central California coast to Turkey Point on the southeast tip of Florida, the United States is home to 99 nuclear power reactors at 62 nuclear plants generating roughly 20 percent of the nation’s electrical energy. But in an industry beset by disruptive technologies and intense competitive pressures, the future of nuclear energy in the U.S. is anything but certain. (more…)

Washington, DC— Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.

– By David Spence, Professor of Business, Government and Society; Professor of Law

In energy policy, political polarization often gets in the way of commonsense solutions to problems.

General Electric recently announced a technological advance that would allow pipeline companies to use drone-mounted cameras to inspect their lines for corrosion and leaks. This is the kind of development that could, with the right regulatory support, make huge strides toward preventing costly and harmful spills and solving other important problems afflicting America’s aging pipeline infrastructure.
