Estimation of greenhouse gases emission From household energy consumption Of a rural community in thailand
According to current environmental degradation, it was stemmed from several significant causes such as energy production and consumption for different activities as well as climate change. These reasons seemed to be more severe until they become global environment issues. However, Thailand participated in Kyoto Protocol to proceed Clean Development Mechanism (CDM) to reduce greenhouse gas emission. Therefore, the researcher aimed to investigate amount of each kind of energy consumption and activities stemmed from average energy consumption per household. The study was conducted in Lam Nam Nan Self Supporting Settlement, Uttaradit Province, Thailand. Then the data were calculated to figure out the amount of greenhouse gas emission from the average energy consumption per household including carbon dioxide, methane and nitrous oxide. The amount of greenhouse gas emission was processed from emission factor obtained from combustion of each kind of energy, except electricity. It was because the value was calculated and adjusted regarding the ratio of fuel consumption of power generation of Thailand. Moreover, expenses caused by environmental effects were also estimated to adjust the proportion of greenhouse gas emission into tCO2eq. After that, it was computed with carbon tax to reflect the social cost of climate change due to the greenhouse gas emission in the atmosphere. The results found that the most energy consumption included diesel oil, followed by electricity and charcoal at 247, 171, 131 kgoe/year, respectively, and the total energy consumption per household was at 805 kgoe/year. When calculating the amount of greenhouse gas emission per household as tCO2eq, it found that the quantity of greenhouse gas in tCO2eq was mostly came from the consumption of electricity and diesel oil at 1,203 and 786 kg/year, respectively. Moreover, the amount of greenhouse gas emission per household as tCO2eq was 3,455 kg/year and the environmental cost per household was 1,669 Baht/year. When considering each activity consuming the energy, the result showed that the amount of energy consumption, the greenhouse gas emission and the expenses caused by environmental effect was mostly stemmed from cooking, transportation. Consequently, there should be a campaign to decrease the consumption of electricity and oil that would be helpful to alleviate the effects of greenhouse gas emission and environmental cost which might be collected as the carbon tax in the future.
