The Dutch Research Council (NWO) recently granted around ten million euros to a large research project that will investigate new concepts for energy-efficient information technology. UT researcher Prof Dr Hans Hilgenkamp is the main applicant of the project, known as NL-ECO. Along with the NWO funding, an additional 2.5 million euros will be made available as co-financing by several participants in the consortium. The digital revolution has benefited mankind enormously. The widespread use of digital devices and technologies, such as computers, internet and data centres, generally make our life more efficient and provide opportunities in areas of application such as medicine. These technologies are energy guzzlers, however. The volume of digital information we process and store and the associated energy costs are growing exponentially.
