With many questioning the sustainability of importing so much food from far away, we are beginning to ask if switching to a vegetarian diet to cut emissions caused by meat production is as sustainable as one might think.
Scientists and policymakers rely on complex computer simulations called Integrated Assessment Models to figure out how to address climate change. But these models need tinkering to make them more accurate.
In a new project, researchers currently developing two facade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque facade sections and a solar thermal blind for transparent sections.
Can thermal solar energy be stored until wintertime? Within a European research consortium Empa scientists and their colleagues have spent four years studying this question by pitting three different techniques against each other.
