Energy prices have become a considerable cost factor for many industry sectors. However, energetically inefficient processes exist in almost every company. Best solution for energy cost reduction is to identify energy efficiency potentials and take appropriate measures. The article analyses an energy consumption for peat extraction process of particular company located in Latvia. Main energy consumers in peat extraction industry are different types of machinery and tractors which use diesel as an energy source. The benchmark has been calculated for the peat extraction process and the results show that around 2.44 kWh diesel fuel is necessary to extract 1 m3 of peat. Comparing and analysing the differences of particular energy efficiency indicators allows to identify the inefficient use of energy, possible financial savings for company and reduction of CO2 emissions.
