My name is Denys Zhukov. I was a participant of exchange program for students between the Institute of Energy Saving and Energy Management of the National Technical University of Ukraine "KPI" and Telemark University College in the period from August 2013 to June 2015. I am very grateful for the opportunity to study Energy and Environmental technology in Porsgrunn. I improved my knowledge from KPI and got new in TUC. This program allowed obtaining new skills, finding new friends, improving my level of English and discovering new countries. Special thanks I want to say to Galyna Strelkova and professional staff of the TUC for the care, understanding and new experience. Thanks so much for this program, it gave me a huge boost in my life.
