Since 2005, the European Union has co-financed 22 projects in 58 cities in the scope of the EU CONCERTO initiative. The objective of these projects is to build and renovate buildings in an energy efficient manner and to utilise renewable energy sources in an intelligent mix. This is a commitment that pays off, as was demonstrated in Brussels at the EU Sustainable Energy Week.
Until now, scientists have assumed that keeping livestock on large steppe grassland contributes to the constantly growing nitrous oxide concentration in the atmosphere and thus to global warming. But now the opposite has been proved: Klaus Butterbach-Bahl's team of five from the Karlsruher Institute of Technology (KIT) have shown that animals grazing on steppe and prairie areas can actually reduce greenhouse gas emissions.
What do the cities of the future look like? What role do they play for global climate change? What influence does the German energy transformation have worldwide? These questions are in the centre of the 2nd Global Sustainability Summer School on 'COMPLEX(C)ITY - Urbanization and energy transition in a changing climate' taking place from 1 to 12 July.
The search for thermoelectrics, exotic materials that convert heat directly into electricity, has received a boost from researchers at the California Institute of Technology and the University of Tokyo, who have found the best way to identify them.
For the first time ever, scientists and stakeholders from all over the world come together this week to have a look at the big impacts picture. They assemble at the 'Impacts World 2013' conference in Potsdam, Germany, aiming at developing a new scientific agenda to systematically address knowledge gaps and to start bridging them.
A new method for the desalination of sea water has been reported. In contrast to conventional methods, this technique consumes little energy and is very simple. This electrochemically mediated seawater desalination is based on a system of microchannels and a bipolar electrode.
