2. 1. Improved energy efficiency in industrial small and medium-sized enterprises : Regional energy efficiency network policy programs

   Author : Ida Johansson; Patrik Thollander; Nawzad Mardan; Inger-Lise Svensson; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional energy efficiency policy; Energy efficiency networks; Industrial SMEs; Barriers; Drivers; Energy management; Regional energipolicy; energieffektiviseringsnätverk; industriella SMF; hinder; drivkrafter; energiledning; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

   Abstract : Despite large potential for improved energy efficiency in industrial small and medium-sized enterprises (SMEs), the full potential is not realized due to barriers to energy efficiency. Two primary ways to realize the potential are to deploy energy management practices and conduct energy audits. READ MORE

4. 2. Biohybrid Polymer Electrodes for Renewable Energy Storage
