Impact of Two Energy Conservation Measures on Reducing CO2 Emissions

The study uses saved energy (the expected annual economy of electrical energy) to describe the impact of energy conservation measures (ECM) on reducing CO2 emissions. Measure 1 (M1) is Reconstruction of the electric drive and control of a basic hoisting machine. Measure 2 (M2) is Reconstruction of the electric drive and control of a fan. A technological analysis for determining losses in percent without implementation of M1 and M2 was made. An investment analysis to determine energy savings in percent and in kWh/y with implementation of M1 and M2 was performed. The value in kWh/y is adjusted with a coefficient of emission factor (CO2) for electrical energy. Further research will involve an analysis of other energy conservation measures and their impact on the reduction of harmful emissions. In the long term and on a larger scale the improvement of the energy balance of technological systems will be favorable for slowing down climatic changes.
