“…Eventually, however, the purchase price will decline, and the new technologies will be more competitive [66,67], and consequently have a shorter PB time compared with light sources with lower luminous efficacy. Indeed, more recent studies demonstrate that LED is a more economical beneficial alternative compared to more traditional light sources e.g., [69][70][71].…”

The aim of this review was to map synergies and trade-offs between sustainable development and energy efficiency and savings regarding exterior lighting. Exterior lighting, such as public road and street lighting, requires significant amounts of energy and hinders sustainable development through its increasing of light pollution, ecological impact, and global climate change. Interlinkages between indicators in sustainability and energy that have positive interactions will lead to a mutual reinforcement in the decision-making process, and vice versa, interlinkages between trade-offs may lead to unwanted and conflicting effects. Very few studies have presented a clear vision of how exterior lighting should be contributing to, and not counteracting, the sustainable development of our planet. This study was conducted through a theoretical and systematic analysis that examined the interactions between sustainable development and energy performance based on a framework using indicators and variables, and by reviewing the current literature. Additionally, 17 indicators of energy efficiency and energy savings were identified and used in the analysis. Most interactions between variables for sustainable development and energy performance (52%) were found to be synergistic. The synergistic interactions were mostly found (71%) in the ecological and environmental dimension showing that environmental and ecological sustainability goes hand in hand with energy efficiency and savings. Trade-offs were found only in the economic and social dimensions accounting for 18% of the interactions identified. This review shows that the interactions between sustainable development and energy performance can be used to establish more efficient policies for decision-making processes regarding exterior lighting.

“…In the analyzed study case an improvement of energy efficiency of 41% could be identified. Regarding the energy saving for lighting, the LED systems are 5% to 20% more efficient compared with compact fluorescent light systems [48]. A saving potential of 10% has been assumed for calculating the effect of LED on the electricity consumption of the whole system.…”

A Vision for Energy Decarbonization: Planning Sustainable Tertiary Sites as Net-Zero Energy Systems

et al. 2021

The power system is changing towards a decarbonized one. The Kyoto protocol and the Paris climate agreement have prompted many nations to approve energy policies based on volatile renewable energy sources (RESs). However, the integration into the grid of the power generated by RESs as well as the electrification of the heating, gas and transportation sectors is becoming a huge challenge. Planning industrial and tertiary sites as net-zero energy systems (NZESs) might contribute to advance the solutions of fully integrating volatile RESs into the power system. This study aims to point out the importance of planning large energy consumer sites such as NZESs, and to depict a holistic modeling approach for this. The methodology is based on a multi-layer approach, which focuses on on-site power generation by RESs, on the improvement of energy efficiency, and on the increase of system flexibility. A qualitative case study has been conducted. It considers the planning of a Net-Zero Energy Data Center located in Germany. Results point out that new interdisciplinary and in particular social analysis methods are necessary. They might be used for accelerating the decision making process during the planning of RES-based on-site power generation systems. Besides, for computation and cooling systems, new technologies that are continuously emerging in the market should be taken into account. If well designed, they contribute to significantly decrease the whole energy demand of data center. Finally, optimal sizing of energy storage systems (electric and thermal) as well as an expedient choice of performance indicators to evaluate technology options are identified as the key factor for decreasing the external energy demand of tertiary sites, such as data center.

“…The lighting systems consumption represents around 20% of the worldwide electrical energy consumption, as well as in the United States of America [1], [2]. The concerns around energy savings encouraged the replacing of the incandescent bulbs for others modern lighting technologies, such as Compact Fluorescent Lamps (CFL) and Light Emitting Diode devices (LED) [3]. Furthermore, incandescent bulbs were banned in some countries, for instance in Brazil, Canada, China, United States and member states of the European Union [4], [5].…”

This paper presents an investigation of the harmonic interaction among lighting devices and its effects on the electrical quantities, billing and power quality. In this study, two types of bulbs, a programmable AC power source, a power quality analyzer, and an oscilloscope were used. Aiming to analyze the impact of the massive introduction of the LED bulbs in the electrical energy system, simulations were realized and several scenarios were considered. The results show that the electrical quantities, such as power factor (PF), displacement power factor (DPF) and total harmonic current distortion (THDi) are function of the harmonic interaction between each harmonic order of each load. Therefore, the characteristics of each load will influence directly in the results. Another contribution of this paper is to show the necessity of reviewing the electrical energy billing rules.
