E-CoRe reversible computing project targets EU energy-efficient computing
The EU-funded E-CoRe initiative aims to cut digital energy use by rethinking computing from the ground up. Digital infrastructure already consumes a significant share of the world’s electricity, and that demand is climbing as artificial intelligence, cloud platforms and distributed systems expand. Against that backdrop, a new European research initiative is focusing on reversible computing as a potential path toward large-scale energy savings in information technology. The project, known as E-CoRe (Energy-efficient Computing via Reversibility), is coordinated by the University of Bologna and supported through the Marie Skłodowska-Curie Doctoral Networks programme. It brings together seven core European partners, spanning universities and research centres, along with eight additional associated partners from academia and industry. Why energy-efficient computing needs a new approach Computers consume energy not only when performing calculations but also when discarding information. According to fundamental physical principles, erasing a bit of information carries an unavoidable energy cost – a constraint often described through the Landauer limit. In conventional computing systems, information is routinely overwritten or deleted, resulting in cumulative energy losses. Reversible computing takes …
