Comparative analysis of the energy efficiency of container terminals in Colombia
Colombian ports and container terminals, as well as their regulators, have been approaching sustainability in terms of greenhouse gas emissions and energy efficiency. This study is part of this effort, as it analyzes the relationship between energy consumption, throughput, and overall costs in container terminals. This is the first research that considers results for all container terminals in the same country for four years. The data analyzed in this study comes from a joint effort between Colombia's Ministry of Transport and the Universidad de Los Andes. These institutions designed and applied a survey to all of the terminals in Colombia, offering an overview of the activities of the port sector from 2010 to 2020. The present study focuses on a specific subset of the collected data: container terminals from 2017 to 2020. Moreover, it uses this data to compare the state of said terminals in Colombia to those in Chile. The results of the analysis showed that energy consumption reduced gradually during the 2017-2020 period. This study also found some promising changes in energy sources and a reduction in energy consumption in different terminals. Compared to previous research, the amount of energy that was either undefined or unaccounted for has also been reduced.
