Massive Data Processing

The increase in massive data processing and computing in datacenters in recent years has resulted in the problem of severe energy consumption, which also leads to a significant carbon footprint and a negative impact on the environment. A growing number of IT companies with operating datacenters are adopting renewable energy as part of their energy supply to offset the consumption of brown energy. In this paper, we focused on a green datacenter using hybrid energy supply, leveraged the time flexibility of workloads in the datacenter, and proposed a thermal-aware workload management method to maximize the utilization of renewable energy sources, considering the power consumption of both computing devices and cooling devices at the same time. The critical knob of our approach was workload shifting, which scheduled more delay-tolerant workloads and allocated resources in the datacenter according to the availability of renewable energy supply and the variation of cooling temperature. In order to evaluate the performance of the proposed method, we conducted simulation experiments using the Cloudsim-plus tool. The results demonstrated that the proposed method could effectively reduce the consumption of brown energy while maximizing the utilization of green energy.

Presently, energy is considered a significant resource that grows scarce with high demand and population in the global market. Therefore, a survey suggested that renewable energy sources are required to avoid scarcity. Hence, in this paper, a smart, sustainable probability distribution hybridized genetic approach (SSPD-HG) has been proposed to decrease energy consumption and minimize the total completion time for a single machine in smart city machine interface platforms. Further, the estimated set of non-dominated alternative using a multi-objective genetic algorithm has been hybridized to address the problem, which is mathematically computed in this research. This paper discusses the need to promote the integration of green energy to reduce energy use costs by balancing regional loads. Further, the timely production of delay-tolerant working loads and the management of thermal storage at data centers has been analyzed in this research. In addition, differences in bandwidth rates between users and data centers are taken into account and analyzed at a lab scale using SSPD-HG for energy-saving costs and managing a balanced workload.

Pumped Storage

A elevada intermitência das fontes de energia renováveis condiciona a produção de energia elétrica, que continua a depender muito dos combustíveis fósseis. Uma vez que existe complementaridade por parte das fontes de energia renováveis, a sua integração conjunta é, sem dúvida, a melhor solução para reduzir esta dependência. Aliado a este facto, poderá coexistir um sistema de armazenamento por bombagem, capaz de gerar reservas hídricas, que serão aproveitadas quando a procura exceder a oferta energética. Procedeu-se ao desenvolvimento de dois modelos: um sobre custos de turbomáquinas e outro que visa o estudo do potencial de recuperação de energia de uma solução energética híbrida com armazenamento por bombagem combinado com fonte de energia eólica. Foram estudadas diferentes combinações para estas duas fontes de energia renovável, analisando o consumo satisfeito e a energia eólica não consumida, tendo-se concluído que o excedente de energia eólica pode ser aproveitado para bombagem. The high intermittence of renewable energy sources determines the production of electricity, which remains highly dependent on fossil fuels. Since there is complementarity between renewable energy sources, their joint integration is a potential solution to reduce this dependency. Consequentially, a pumping storage system capable of generating water reserves can coexist, which will be used when demand exceeds the energy supply. Two models were developed: one based on turbomachinery costs and the other based on the potential of energy recovery of a hybrid energy solution with pump storage combined with wind energy. Different combinations were studied for these two sources, analysing the satisfied consumption and the wind energy that is not consumed, in which it was concluded that the surplus of wind energy can be used by pumped storage.

The object of research is the implementation of the principles of Industry 4.0, in particular game theory and blockchain, for the development of energy. One of the obstacles to development is the problem of energy supply in modern economic conditions in terms of achieving sustainable development goals. In the course of the research, a systematic approach to the critical analysis of scientific sources of information related to the development of the energy sector, in particular renewable energy, was used. The scientific result of the systemic interaction of distributed generating devices with «smart» consumers using the principles of Industry 4.0 has been obtained. These principles make it possible to increase the level of efficiency of the power system, to reduce the total cost of operating the power system. And also to reduce power losses, improve network performance while reducing CO2 emissions and negative impact on the environment. The possibility of implementing the provisions of Industry 4.0 as a prerequisite for an economical supply of energy is given. The research methodology is proposed based on a critical analysis of the sphere of economics and management in the energy sector in the period 2011–2021. The possibility of using the Vehicle-to-Grid concept based on Industry 4.0 as a component of the energy system is considered. Due to this, a method for managing the sale of electricity is proposed, based on game theory, and taking into account the autonomous response to demand and the interaction of distributed generation in smart power distribution systems using non-cooperative games. The authors have identified the possibilities of energy blockchain technology in terms of efficient energy supply and transformation of commercial relations in the energy market. Focuses on blockchain for energy as part of ensuring energy sustainability, providing opportunities for the development of renewable energy sources. A list of breakthrough energy technologies for the last 5 years has been highlighted with the aim of their implementation to improve the levels of quality and safety of human life. In particular, according to the Massachusetts Institute of Technology, there are 7 technologies out of 50 investigated, directly related to energy, moreover, the overwhelming majority of these technologies are related to renewable energy.

Energy Sources

India is a developing country, with a population of about 1,387,297,452. India requires a lot of energy both for development and running all its systems smoothly. Most of the energy consumed in India is in electrical form. The electrical energy consumption of India is around 1,137.00 billion kWh of electric energy per year. When counted per person, this energy comes to an average of around 841 kWh. When looking at the tactical data given out by the Indian government, 80% of the total electrical energy is produced using fossil fuels, even though there is a lot of abundant availability of renewable energy here in India. This paper studies the various renewable energy sources currently utilized in various sectors in India. This paper looks at the effect of technical efficiency gains on energy use in industrial, agricultural, and other sectors in India, at varying levels of aggregation. This paper gives the present status of energy sources and utilization areas. Although around 80% of the average temperature zone is available in the Indian subcontinent, the electrical energy produced in India via solar energy is less than around 1.3% of total consumption. India currently produces 63.730 GW, which is very less when compared to the total energy required. Similarly, India produces 32 GW of electrical energy from the wind sector, which is very little compared to the total energy consumption.
