Over the past thirty years, the European food industry has failed to make significant improvements in energy efficiency, says Dutch-sponsored researcher Andrea Ramírez. Her conclusion is based on an analysis of energy consumption, energy efficiency and developments in the food supply chain in 13 European countries.
Andrea Ramírez investigated the energy management of the European food sector. She found out that while production growth has increased the energy requirements of the sector by an average of 1.8 percent per year, savings in the amount of energy needed to produce a unit of product have only lead to an energy saving of 0.2 percent per year. The net balance is therefore negative.
There are a number of important reasons for the growing energy requirements in the food industry: the increased demand for feed production, a growing consumption per capita and an increase in the amount of transport – larger quantities of food have to be transported over greater distances.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
