Saturation, energy consumption, CO_2 emission and energy efficiency from urban and rural households appliances in Mexico

摘要

Energy usage and energy efficiency are of increasing concern in Mexico, electricity generation principally depends upon fossil fuels. On one hand, the stocks of these fuels have been confirmed to be critically limited. On the other hand, in process of electricity generation by means of these fuels, a number of poisonous by-products adversely affect the conservation of natural eco-system. This paper focuses on estimation of energy consumption, energy savings, reduction of emissions of CO_2 for use of urban and rural household appliances in Mexico between 1996 and 2021. The analysis concentrates on six major energy end uses in the residential sector: refrigerators, air conditioners, washing machines, TV set, iron and heater. It is estimated that by 2021 there will be a cumulative saving of 22,605 GWh, as a result of the implementation of government programs on energy efficiency that represents a cumulative reduction of CO_2 emissions of 15,087 TgCO_2. It means that Mexico can reduce in 5650 MW the generation capacity of national electricity system, which is to avoid burning 40.35 MM barrels of oil. The findings can be useful to policy makers as well as household appliances users.
