TL;DR: In this paper, the authors analyzed the effect of physical distancing measures regarding mobility on the energy consumption trends for the Brazilian energy system and its subsystems (Northeast, North, South, and Southeast-Midwest) trends were evaluated by the Joinpoint software, and the analysis comprehended the period between January 1 and May 27, 2020 Daily load data was grouped into weeks, with the calculation of weekly percentage changes considering a 95% confidence interval andp < 0 05 The weekly electricity loads were compared in the periods before and after the isolation decrees were enforced in Brazil (March
Abstract: The implementation of mobility restrictions and home office schemes due to the COVID-19 pandemic have influenced electricity consumption patterns and levels This study analyzes the effect of physical distancing measures regarding mobility on the energy consumption trends for the Brazilian energy system and its subsystems (Northeast, North, South, and Southeast-Midwest) Trends were evaluated by the Joinpoint software, and the analysis comprehended the period between January 1 and May 27, 2020 Daily load data was grouped into weeks, with the calculation of weekly percentage changes considering a 95% confidence interval andp < 0 05 The weekly electricity loads were compared in the periods before and after the isolation decrees were enforced in Brazil (March 15, 2020) Statistically significant decreases were observed in the levels of electricity consumption, with trends represented by two joinpoints Due to the different profiles of consumption across the geographic regions, the resulting electricity dynamics were also different This is the first study to employ joinpoint analysis for the calculation of energy consumption trends focusing on the COVID-29 pandemic Data presented herein is unique, in its focus on Brazil, which enables more accurate implications to be drawn for Brazilian policy makers

TL;DR: This perspective paper has been suggesting and discussing some of the energy transition opportunities facilitated by COVID-19 pandemics, where each is having some pros and cons related to energy consumptions.
Abstract: This perspective paper has been suggesting and discussing some of the energy transition opportunities facilitated by COVID-19 pandemics. A strong base in a cluster of innovative technologies is expected. They have been spread out of distance meeting and learning, massive home office use, the growing popularity of e-shopping, raise in e-socialising, related to this intensifying the data transmissions as 5G and considering 6G, urban and sanitary reforms, remote and robotic health monitoring and even treatment, related preference to shortening the commuting, intelligent traffic control, strengthening to favour self-driving autonomous vehicles, advanced digital manufacturing challenging remote and distance production operating, remote construction and building as remote drilling, automated waste management collection and treatment, and also applications of novel ways for deliveries as, for example, drone. Each of them is having some pros and cons related to energy consumptions. Are the beneficial features able to offset its own energy consumption and the rebound effects of increasing demand?
TL;DR: The survey identifies often challenges and various significant issues that still essential to be addressed to develop a cost effective, efficient, long‐lasting, and almost maintenance‐free energy harvesting systems for WSNs along with trail to their possible solutions for future perspectives.
TL;DR: This paper proposes and demonstrates a new smart energy meter following an IoT approach and its associated costs and benefits, and the provided solution is validated and demonstrated in real‐life environments.
TL;DR: In this paper, the authors analyze the impacts of the Coronavirus (COVID-19) outbreak on the oil and gas industry and give a perspective of the post-COVID19 oil and Gas market.
Abstract: The Coronavirus (COVID-19) outbreak hit the global economy like a tsunami. Every aspect of human society, including the energy industry and market, is affected by this pandemic. The pandemic has affected prices, demand, supply, investment, and several other aspects of the energy sector, including the oil and gas industry. This article is aimed to analyze the impacts of COVID-19 on the oil and gas industry and give a perspective of the post-COVID-19 oil and gas market. Results of this article show that COVID-19 impacts the oil and gas industry. The short-term impact is nearly 25% decrease in petroleum consumption, slowly recovering to its former amount and even growing more. The long-term impacts are the 30% to 40% decrease in the CAPEX and R&D investments over the oil and gas market, which is a regional scale in the United States, caused oil exploitation projects to decrease from more than 800 in 2019 to 265 in 2021. And it is predicted to reduce the competitiveness of oil and gas vs other energy carriers such as ever price-decreasing renewable energies. Thus, the oil and gas industry has to change rapidly before losing a substantial energy market share. Finally, this article discusses acknowledging oil and gas trade as a part of World trade organization (WTO/ECT) regulations. And considering it a general energy commodity. An act that reduces the freedom of action of oil-exporting governments and great oil cartels and protects their interests in a globalizing competitive energy market.
