Energy Efficiency in Motor Systems

Paolo Bertoldi is as Senior Expert working at the European Commission since 1985. Since May 2001, he is at the European Commission Joint Research Centre (Ispra, Italy), in charge of research activities on energy efficiency policy analysis, the efficient use of electricity (in particular ICT) and innovative policy instruments for energy efficiency (e.g. white certificates, financing mechanisms, ESCO, EPC, emission trading). He also manages the Covenant of Mayors research activities at the JRC. He has been a Contributing Author for IPCC Assessment Report 4, Lead Author for IPCC Assessment Report 5 and the Special Report on 1.5 C and recently he has been nominated Lead Author for IPCC Assessment Report 6.
