Energy Savings in Public Lighting, Reduction of Light and Atmospheric Pollution in the City of Cuenca-Ecuador

Abstract

AbstractThis article presents a methodology to estimate the volume of carbon dioxide CO2, which has not been emitted into the atmosphere by the use of luminaires with a switchable energy system that have been installed in the public lighting system in 2019 in the city of Cuenca - Ecuador. It shows the important results of energy saving in public lighting, the reduction of CO2 emissions and light pollution, because there is no evaluation to see the effectiveness of the use of these systems in Cuenca. To achieve this purpose, the number of luminaires with switchable systems installed in 2019 was established and their level of power reduction was verified in the laboratory, the amount of energy saved, the reduction of light pollution and the volume of CO2 that it has stopped emitting into the atmosphere. Finally, as a consequence of the study, it is established that the use of luminaires with a power variation system is considered a valid technology that contributes to energy savings that reduces CO2 emissions and reduces light pollution without significantly affecting the provision of lighting.KeywordsLightingEnergy savingLighting pollutionEmissionLuminaires
