Impacto de buenas prácticas en el uso de electrodomésticos eficientes en la reducción de las emisiones de CO2 en los hogares urbanos de Ibagué, Colombia

Abstract

The management of energy efficiency is necessary to demonstrate the accelerated consumption of energy in recent decades. The CO₂ emission avoided was estimated by projecting the impact of good practices in urban homes in Ibagué through the use of efficient appliances. A semi-structured survey was used to estimate current consumption and CO₂ emissions derived from the monthly use of existing equipment in the home. Then, the emission in four scenarios was projected to change current appliances for the next 20 years. Changing the refrigerator, washing machine and incandescent or fluorescent lamps reduces CO₂ emissions from 55.8 Gg to 52.8 Gg by 2039. A change of the 100% of the appliances by efficient ones would cause a reduction in emissions or additionality of around 40 Gg CO₂ during 20 years. However, effective programs that link the entire population are required, since only 56% of the households surveyed want to exchange their current equipment for equipment with greater energy efficiency, even if they are clear about the cost and CO₂ emissions savings. This study also motivates the execution of local strategies that encourages the modification of habits, consumption policies and use of efficient equipment is encouraged.
