Economic-environmental impacts on reduction of energy consumption in technical high schools during the COVID-19 pandemic: case of Manzanillo, Mexico

A study is presented on the economic and environmental impacts, due to the reduction of electricity consumption in a Technical High School in Manzanillo, Mexico, during the COVID-19 pandemic, as well as the impacts generated by the reduction of student mobility. This research shows an analysis of the reduction of electrical energy consumption, the reduction of monthly economic costs and CO₂ emissions in the studied institution, these impacts on student mobility during confinement between November 2019 and October 2021 are also analyzed. Results show electrical energy savings of approximately 60MWh during this period, about 34 TnCO₂ and an economic saving of 8654 USD. It has also estimated an economic saving in student mobility of approximately 312,840 USD and a reduction in emissions of the order of 64 TnCO₂.
