In the 21st century, energy supply has been one of the challenging issues that the world is facing. This is due to growing populations which results in more homes, businesses, and industries and has resulted in a large number of new appliances that increased the energy demand to a new level. The electric system we are using today is a one-way energy flow. Smart grid has emerged as the solution of continuously increasing demand. It is the future of electric energy system and also the power grid for upcoming generations. SG system works on the dual technique, that is, it counts electricity flow and the information which could deliver and distribute the energy universally by automating the existing electrical network.

The articles analyze the problems of building electric power systems of the future on the basis of Smart Grid concepts and taking into account the introduction of electrical installations of distributed energy resources. The problems of introduction of certain technologies into the Unified Energy System of Ukraine are considered and the ways of their solution are offered.

Wind and solar energies present a time and space disparity that generally leads to a mismatch between the demand and the supply. To harvest their maximum potentials, one of the main challenges is the storage and transport of these energies. This challenge can be tackled by electrofuels, such as hydrogen, methane, and methanol. They offer three main advantages: compatibility with existing distribution networks or technologies of conversion, economical storage solution for high capacity, and ability to couple sectors (i.e., electricity to transport, to heat, or to industry). However, the level of contribution of electric-energy carriers is unknown. To assess their role in the future, we used whole-energy system modelling (EnergyScope Typical Days) to study the case of Belgium in 2050. This model is multi-energy and multi-sector. It optimises the design of the overall system to minimise its costs and emissions. Such a model relies on many parameters (e.g., price of natural gas, efficiency of heat pump) to represent as closely as possible the future energy system. However, these parameters can be highly uncertain, especially for long-term planning. Consequently, this work uses the polynomial chaos expansion method to integrate a global sensitivity analysis in order to highlight the influence of the parameters on the total cost of the system. The outcome of this analysis points out that, compared to the deterministic cost-optimum situation, the system cost, accounting for uncertainties, becomes higher (+17%) and twice more uncertain at carbon neutrality and that electrofuels are a major contribution to the uncertainty (up to 53% in the variation of the costs) due to their importance in the energy system and their high uncertainties, their higher price, and uncertainty.

The National Electric Energy Agency (ANEEL) of Brazil, in a bid to encourage energy-conscious energy consumption, has proposed a new sustainable energy tariff modality (the White Tariff) based on off-peak usage. This study aims to compare and contrast situations in which the White Tariff alone is used, and where it is combined with power generation from a generator set or a photovoltaic cell energy system to reduce energy costs. Furthermore, economic, environmental, and social advantages are outlined in the project summaries. Interviews and documentary analyses were conducted in a technology park that uses only the White Tariff and in condominiums that combine the White Tariff with a generator set or a photovoltaic cell system. The data generated was fed into the database of the Horosazonal software to obtain an overview of these companies. Results show that the company adopting the White Tariff alone achieved 19% and US$14,684 in annual savings. However, when the White Tariff is combined with a generator set, the smart grid project proved to be more efficient over time as it obtained an annual benefit of US$35,832 and 62.38% savings. In contrast, the smart grid project combining a photovoltaic cell energy system with the White Tariff achieved an annual benefit of US$52,712, with 68.31% savings and was 1.3 to 5.3 times more profitable than other projects, demonstrating that it was the best smart grip project studied. Furthermore, opting for the White Tariff produced advantages such as a reduction in energy consumption expenses, contributing to a reduction in power outages and blackouts, reduction in greenhouse gas emissions and boosting the company image within society. This study shows that energy-conscious consumption combined with the use of renewable energy sources is environmentally and economically advantageous and can provide future generations with a healthier environment in which people can make use of natural resources in a sustainable manner that is sustainable for planet earth.

The contemporary epoch is under a serious energy crisis. With increasing energy demands and exhausting energy resources, this catastrophe is difficult to get through. Sustainable and efficient utilization of energy resources can pave the way to a world with, energy for all and energy forever. Electrical energy, the most widely used form of energy, if used efficiently and sustainably can ease the overall energy crunch. This paper gives an insight into how the adaptation of SMART GRID TECHNOLOGY can consequently relieve the pressure on energy demand and secure the energy resources for the future

Public confidence and trust in higher education has declined (Johnson and Peifer 2017) and the future of the higher education sector has been questioned (AGB 2020). More specifically, the discipline of sociology is considered to be in “crisis” and applied sociological approaches are offered as a solution (Graizbord 2019; Weinstein 1997). The purpose of this introduction article as well as the broader special issue is to explore the nature and state of applied sociology in Canada. With a collection of seven articles authored by Canadian sociologists on topics including application research, reflections on process, and teaching practice, this special issue provides a platform to discuss and showcase the distinct nature and contributions of applied sociology in Canada as well as highlight the work of Canadian applied sociologists.
