Since his studies, a five-year masters’ course in Economics and Management at the University of South Bohemia, Tomáš Voříšek (born 1977) has mainly specialised in assessing technical and economic conditions and the options for using renewable energy sources, especially biomass and biogas. Since joining the company (2001), his professional focus has gradually expanded to secondary energy sources, in particular waste, and he has become the organisation’s main specialist for the entire area of AES (alternative energy sources). In accordance with the firm’s focus, his engagement with AES has taken the perspective of evaluating economic and energy efficiency and their environmental benefits in order to continue to explore the options for possible improvement. Since 2010, he has held the position of technical director and is responsible for the professional quality of all technically-oriented corporate outputs, including projects focusing on energy savings (energy audits, feasibility studies, EPC). He has also spent many years endeavouring to promote similar themes in the transport sector (i.e., introducing more efficient power sources and fuels, etc.).
