Abstract
The analysis and selection of the most favorable energy generating product for the combustion and transformation into thermal energy for technological needs, heating and preparation of consumable hot water (CHW) of a production plant in the continental climate area were carried out. The analyzed energy generating products are: natural gas, biogas, wood chips, pellets and extra light heating oil. Even with 1.5 – 2.0 times higher investments in thermal energy plant, renewable wood chips are, from the ecological and economical perspective, still the most favorable drive fuel for the production of thermal energy. In this case the price of 1kWh of thermal energy is several times lower (3 – 7 times) than the price of 1kWh of thermal energy obtained by the combustion of other analyzed drive fuels. The increase in the unit price of wood chips does not strongly affect the sustainability and cost–efficiency of the price of 1 kWh of thermal energy. The emission of harmful gases into the environment is the lowest.
