Impact of Human Activity on Local Climate Change in Veľké Turovce by Heating and Possibilities for Carbon Dioxide Decrease

Abstract

Abstract The paper is aimed at detecting CO2 emissions from heating process of households in Veľké Turovce. It offers solutions for 100 % and 20 % replacement of conventional fuels by solar collector systems. In the village, 242 households heat by natural gas during average length of 21 weeks a year. Average amount of energy consumed in heating process after conversion is 18,503.06 kWh per household. For 100 % replacement of natural gas, 63 units of vacuum tube solar collector type Watt CP C 9 are required. In average duration of 23 weeks a year, 12 households heat by brown coal with average consumption of 20,339.75 kWh. For complete replacement, 69 pieces of solar collectors are required. The remaining 18 households heat by firewood in average duration of 22 week a year. The consumption of one household represents in average 19,125.07 kWh. In this case, the replacement of 100 % of firewood energy requires 65 pieces of solar panels. The amounts of saved CO2 emissions by collector system replacing 100 % of natural gas represent 926,336.39 kg of CO2 for 242 households. For 12 households heated by brown coal, it represents 152,767.65 kg of saved CO2 emissions. Last but not least, 30,553.53 kg of CO2 represent the amount of saved CO2 emission for 18 households heating by firewood. Prices of collector systems in case of 100 % replacement of conventional fuels would be 37,111.45 € for natural gas, 40,356.79 € for brown coal, and 38,203.23 € in case of replacement of firewood
