The SARS-CoV-2 virus caused crises in social, economic, and energy areas and medical life worldwide throughout 2020. This crisis had many direct and indirect effects on all areas of society. In the meantime, the digital and artificial intelligence industry can be used as a professional assistant to manage and control the outbreak of the virus. The present article’s objective is to investigate the effects of COVID-19 on each of the various fields of medicine, industry, and energy. What sets this article apart is studying the impact of artificial intelligence and digital style on reducing the damage of this fatal virus. Energy and related industries are of the areas affected by the SARS-CoV-2 virus. The most exciting approach in this article is to encourage countries with economies based on non-renewable energy to develop solar and wind energies. Renewable energies can operate well in the event of another phenomenon such as COVID-19 and reduce the virus’s destructive effects and lead to economic prosperity.

The new coronavirus SARS-CoV-2, known as COVID-19, was introduced by the World Health Organization (WHO) in late 2019. Since late December, it has spread rapidly from Wuhan, China, to other countries and led to a worldwide pandemic. The disease has caused unprecedented shortages in healthcare, care equipment, and many other industries. COVID-19 placed restrictions on the supply of raw materials in traditional style industries. However, a small number of these shortcomings were detected in digital industries under Industry 4.0. Some industries, such as intelligent sensors, nanotechnologies, Internet of Things and blockchain technologies, and artificial intelligence, operated with high success (Bragazzi 2020; Kulachinskaya et al. 2020; Wang et al. 2020 ). In the last 20 years, scientists and physicians have shown more interest in artificial intelligence (AI) technologies. First of all, many have attempted to provide a precise definition of artificial intelligence.

According to some authors, artificial intelligence is a machine's capacity to decode and understand the input in an intelligent system. Some believe that artificial intelligence is a novel method of managing information in a business model (Lüdeke-Freund 2010) . According to Schilirò (2020) , artificial intelligence can be divided into five broad categories: (1) computer vision, (2) natural language, (3) virtual assistant, (4) robotic process automation, and (5) Advanced Machine Learning. Digitalization significantly affects global trade and investment. Moreover, digital data and information are new concepts that can be considered similar to new oil resources today. More work completed on this issue leads to the improvement of solutions to global problems. Furthermore, data, ideas, technologies, and best practices in this field affect investors' decisions worldwide, which turn into opportunities to monetize data. At the global level, this information has significantly contributed to the increase in world GDP over the past decades, and technologies based on artificial intelligence and digital show a more significant share of the impact on growth than the global trade in goods (Schilirò 2020 ). In the present study, the authors attempt to examine the technologies, effects of artificial intelligence, and the process of digitalization on communities after the outbreak of the COVID-19 virus. For this purpose, the authors first discuss the applications of this model of technology in education and treatment. Afterward, the programs and works performed in this area are introduced. Then the authors investigate the entry of this field into industries and companies. Finally, the impact of this industry on energy is reviewed (see Fig. 1 ).

The COVID-19 pandemic has had an impact on energy consumption, markets, and technology and will continue to do so. Despite the fact that the epidemic has wrecked devastation on human civilization, it will enable a quick growth in renewable energy, which will contribute to long-term growth. The building of renewable infrastructures will help speed up the post-pandemic economic restoration. Building on a broadbased and distributed energy storage system will be an important way to ensuring energy supply security depending on the renewable-dominated system. AI technology, which were essential in combating the epidemic, will also aid in the future growth of energy by making it more clean, efficient, and intelligent. The influence and use of artificial intelligence instruments and digital style on industry and energy following the outbreak of COVID-19 is explored in this paper using recent study material.

Technology in education, disease prevention, and treatment

The digital technologies and technologies under the title of the Fourth Industrial Revolution have assisted in providing distance education, remote monitoring system, and sending information from distant places to health bases (Javaid et al. 2020) . The video surveillance based on artificial intelligence and machine vision effectively reduced the work of doctors and hospital managers in these critical situations. Digital technologies offer methods for the proper isolation of infected patients to reduce the high risk of mortality, accelerate drug production, treatment, and care, which may also contribute to epidemics similar to COVID-19 in the future (Javaid et al. 2020) . With the outbreak of COVID-19 and the increase in mortality, scientists worldwide are looking for new technologies to screen infected patients at different stages, find the best clinical trials, control the spread of the virus, etc. Recent studies have revealed that machine learning and artificial intelligence are more promising, faster, and more reliable technologies than humans in healthcare. In this regard, it should be noted that not all technologies are intended to remove humans from the cycle of interactions in the medical industry but to provide accurate decisions to physicians (Lalmuanawma et al. 2020) . Although it is uncertain how carbon emissions would affect the planet after the COVID-19 outbreak, the energy intensity effect and the economic structure effect have opposing effects on carbon intensity drop, respectively, accelerating and delaying it. The energy mix effect, on the other hand, has a minimal impact on carbon intensity reduction. The outcomes of the deconstruction of industrial carbon intensity demonstrate that technological and structural factors varied greatly between industries.

A short brief explanation of rehabilitation and the effect of medicine over the COVID-19

Our healthcare system relies heavily on rehabilitation. Even so, during a pandemic response, when the healthcare system's attention switches to the wise management of a surge of severely ill people, it is highly vulnerable. During the rapid growth of the COVID-19 pandemic, the problems of altering the roles of treatment providers and systems reveal insights that may help systems manage their reactions as they deal with these concerns. The impacts of the pandemic will last well beyond the immediate emergency response. Preparing for future pandemics is a critical long-term strategy for maximizing our ability to react to future problems in our healthcare system's rehabilitation services. Infection prevention and control methods and supportive care, such as supplemental oxygen and mechanical ventilatory support, are being used in the treatment of COVID-19. The US Food and Drug The advantages of Industry 4.0 technologies over the COVID-19 crisis Javaid et al. (2020) describe the effects of the Fourth Industrial Revolution on coronavirus prevention. Artificial intelligence and new technologies have also been effective in preventing coronavirus disease. This critical movement is including the use of virtual reality by physicians and medical staff to reduce the risk of coronavirus disease, which is applied to create a completely stress-free environment for training medical staff (Haleem and Javaid 2019; Ren et al. 2020) .

Artificial intelligence for COVID-19 crisis management initially helped people with thermal imaging equipment scan public spaces, which could be used for social distancing. The infrared cameras were used to monitor crowds at airports, public places, and train stations across China. These cameras are also applied to detect the faces of people with a high fever. They can scan 200 people per minute and see people with body temperatures higher than 37.3°under the pretext that they may suffer from the disease (Naudé 2020). Imagine a time when there was a crisis similar to COVID-19, and there was no possibility of using these technologies. In such cases, due to a lack of sufficient information about this disease, people would maintain social relations with each other and use traditional findings for their treatment.

On the other hand, doctors would treat patients with simple laboratory facilities and devices. Also, in the corridors of medical centers and hospitals, people would be move with high density. Hence, the result would be nothing but the spread of the virus and the increase in infections and deaths due to COVID-19. However, nowadays, with digital technologies and modern technologies, advanced image processing cameras can be used in medical centers' corridors to distinguish people suspected of being infected. Industry 4.0 technologies can be described as professional assistants for all community sections (see Table 1 One of the categories of Industry 4.0 is mobile technology, which is the article's title due to its high importance. Regardless of the type of operating system and features, mobile technologies are of great importance in people's daily lives (Javaid et al. 2020 ). In the post-COVID-19 era, this technology is efficient and valuable. Since addressing mobile health service needs is the only acceptable way to connect to the rest of the world, facilities, sensors, and chips can also control the issue. Smartphones, without a doubt, are based on these operating systems. In today's medical industry, various countries make use of innovative technologies. For example, Germany has implemented a tracking program based on smartwatches, which uses pulse and temperature. It transmits the resulting data to areas of health bases for further analysis (Heidel et. al. 2020) . This feature has been applied in a limited and experimental way to evaluate people with coronavirus disease. People are split into information assets by location in this method. The smartwatch user may develop coronavirus disease due to changes in the reference program, such as pulse and temperature.

In the same way, that area is under the control of the health staff. With this system, individuals' incidence and the speed of disease transmission can be significantly assessed (Whitelaw et al. 2020) . Every country takes the importance of mobile technologies seriously based on the number of casualties in this crisis by reviewing the release dates and launches of applications contributing to the COVID-19 problem (Lalmuanawma et al. 2020) . It can be seen that most of the countries that produce these applications started operating in "April and May." In the meantime, only three countries, Austria, Singapore, and Israel, contributed to the COVID-19 crisis in their region with this technology in March and about a month and a half earlier than other countries.

As shown in Table 2 , different countries have taken a step forward in software technologies to control diseases such as COVID-19. Each of them tries to manage and evaluate the condition with a part of artificial intelligence divisions. As mentioned in the previous part related to Germany, the application that was run in that country was also implemented on a smartwatch and used in other technologies such as Bluetooth and other sensors in a smartphone. For example, a program in Ghana is applied to study the population in each region. City-wide video surveillance cameras monitor each area of the city's population and display it online on the mobile platform. It allows people to check the area's population before leaving home or work for essentials (Whitelaw et al. 2020 , Wang et al. 2021a , 2021b . Artificial intelligence and big data can be highly effective in education, especially in preventing COVID-19 disease. Big data come with three attributes: speed, volume, and variety; each of which can be interpreted as follows:

& Speed in terms of information processing & Volume in terms of the high amount of data in each process & Diversity in terms of the number of different sources and channels that can produce big data

There are different types of big data that are divided into three categories based on their source type:

& Imaging-based data (e.g., data mining, extracting highdimensional information from images) & Data based on wearable sensors & Digital and computational data by smartphones and the Internet Any style of this data can be effective in treating COVID-19 (see Fig. 2 ). These issues can be necessarily provided by various valuable software in the previous section on corona outbreaks, or the data type can be changed . ICT is a "helper" that helps disseminate information about the outbreak to large segments of the worldwide population in ways that would be impossible without it. Educators and administrators must be best ready to use ICTs in education throughout the COVID-19 crisis and beyond. This crisis is the perfect opportunity for government-led projects in schools to try out new ways to reach out to kids, learn from other nations, and incorporate practical techniques into regular education. Also, to generate practical student learning experiences, digital technologies must be integrated into sound instructional programs. Governments must undertake the required preparations to better map teaching and learning demands in future educational crises. This necessitates collecting comprehensive survey data on ICT use in schools as a necessary first step in adequately guiding policymaking. The media, particularly social media, can also inform pupils about the virus and basic hygiene. An animated music video advocating handwashing and other preventive steps to guard against the virus has gone popular in Vietnam.

As the business relies more on technology, new production techniques such as 3D printers and industrial automation have increased in factories since the advent of the COVID-19. Moreover, import incentives have been declined. During this period, smartphones became increasingly widespread and accelerated digital globalization (Schilirò 2020) . The global economy has been affected strongly by the outbreak of the corona. For instance, industries such as tourism, aviation, industry, and manufacturing have suffered in the 3 months of the disease since the supply chain management of sectors such as automobiles and electronics faced problems with the closure of international flights. The lack of supply of spare parts worldwide is among them. The coronavirus had the most significant impact on the manufacturing industry in China, the USA, and Germany (Cai and Luo 2020) . COVID-19 pandemic and the effect on industrial parts around the world is an example in India. The lockdown has caused labor shortages around the country, which has increased transportation options' resource limitations. Businesses that rely on a "just in time" or "restricted inventory" approach are likely to be disrupted by delayed supplies. Other enterprises and other services have also been shut down, exacerbating the situation. Due to the complete suspension of public transportation, personnel responsible for handling and delivering essential commodities and supplies must now walk to work. The same is particularly exhausting for people living on the fringes of the informal economy, resulting in more low productivity. As indicated in Table 3 , if the virus is present in communities for a long time, the expert's knowledge becomes more about this virus. This virus is accompanied by alterations every moment and changes its symptoms. It can be said that the importance of artificial intelligence and digital style on the life of the industry is the only industry the effects of which are visible in the short term, and there is no need for a long time to discover the truths. 

In the last 20 years, scientists and physicians have shown more interest in artificial intelligence technologies. First of all, many have attempted to provide a precise definition of artificial intelligence. According to some authors, artificial intelligence is a machine's ability to decode and understand input in an intelligent system. Some believe that artificial intelligence is a new way to manage information in a business model (Lüdeke-Freund 2010). Among the industries, the food industry is also of great importance. In situations similar to this, the need for proper nutrition for a growing population increases. This need interacts directly with systems in the field of agricultural and food sustainability. That is why numerous companies create activities to use artificial intelligence technologies to solve multiple problems and save valuable energy resources. The condition for accepting these technologies in process management is to possess sustainable business models (SBM), which can positively affect the whole system without harming the environment and society (Lüdeke-Freund 2010; Stevens and Shearmur 2020). According to Fig. 3 , deep learning, computer vision, physical and software robots, and processing are the major technologies among artificial intelligence technologies that improve industries' quality and performance. Machine vision and deep learning is a method to analyze data, which builds analytical models for a system and is based on the fact that the system can understand the information from the data, identify the models alone, and make the final decision with minimal human intervention. For instance, in the agricultural sector, programs have been developed with artificial intelligence technology, which can detect plant pests with photography (Di Vaio et al. 2020) .

Physical and software robots are advanced machines that can solve small and large problems. For example, most people know robotic agriculture, in which they speed up tasks such as weeding or packing fruits. Robots are valuable assets allowing farmers to use their processing information about their profession to obtain various data such as temperature, humidity, fertilizer, soil condition, and water consumption and receive and control them through the robot by optimizing them in the next step (Di Vaio et al. 2020) .

Artificial intelligence has other applications in the food industry as follows:

& Sorting food products & Improving product quality & Ensuring compliance with health standards & Preparing and producing drinks A successful example is the Kankan company; they continuously work to create intelligent solutions to improve health. The system, which can also be used in restaurants, uses face recognition and object recognition cameras to monitor workers to see if workers wear cooking hats and masks following food hygiene laws. Moreover, this software extracts and sends all the images to the management for review (Di Vaio et al. 2020) . Digitalization is hugely influential in the industry, especially in the agricultural sector, accounting for half of the world's water consumption (see Table 4 ). Nowadays, drones are used in farms and agricultural sectors for the reasons as following: 

Pandemics triggered by COVID-19 spread to almost every country on the planet. Because energy is one of the most important aspects of modern life, it has been heavily influenced. During the pandemics, a slew of research and analyses developed, each focusing on a different component. However, post-pandemic development will be an essential factor. COVID-19 reached almost every country on the planet. Because energy is one of the most important aspects of modern life, it has been heavily influenced. The authors have attempted to investigate the effect of digitalization on education, treatment, and industry by examining various sources. Undoubtedly, renewable and non-renewable energies and resources have benefited from artificial intelligence and digital style advantages.

COVID-19 revolutionized the energy sector and posed challenges, increasing countries' interest in renewable energy technology. Meanwhile, due to the lack of financial and development resources in African countries, many countries began to import solar and wind energy technologies (Gebreslassie 2020 ). There are two challenges for customers of renewable sectors: (1) consumer ignorance and (2) lack of initial capital. Most customers are in this situation, and the vacancy of government advertising and promotion policies becomes tangible. The plastics industry is one of the oilrelated industries. After the outbreak of COVID-19, there was a sudden increase in demand and use of plastic products to protect the general public, patients, healthcare workers, and services. Extensive use of such products causes various problems both in terms of supply and disposal of waste, and the vital point is that most of these products are contaminated with the disease or suspected of having the disease, which must be staved off very carefully (Klemeš et al. 2020) . Nowadays, artificial intelligence is used for this separation of waste. These systems are installed in waste disposal plants and can effectively waste separation and recycling and recycling speed (Vanapalli et al. 2021 ).

In the USA, more than 300 drilling rigs were shut down, the country in which the significant oil power is provided through shale oil from 2014 to 2019 with a value of $100 oil in 2011 that became an attractive and profitable price for the country. In the context of the COVID-19 crisis, the USA is now being challenged by the low income of this oil in the oil industry's low market demand after the coronavirus epidemic (Jefferson 2020) . Venezuela faces US sanctions in addition to low demand for this oil and soft exports because the crude oil produced in this country is heavy and must be diluted to pass through pipelines by factors such as naphtha. The USA has imposed sanctions on the export of diluents to the country, and the government is not in a favorable position in terms of energy in the post-COVID-19 era (Jefferson 2020) . In Nigeria, with relatively heavy oil similar to Venezuela, it is clear that the country cannot cope with the COVID-19 energy crisis. The government has discounted $4 a barrel since the end of April 2020 and has not sold more than half of its oil capacity so far. In Canada, despite possessing several light oil fields, since the end of March 2020, it was announced that the country's economy is on the verge of recession. The Alberta Saskatchewan region, known as the heart of Canada's oil industry, is anticipated to lose more than 200,000 jobs and reduce its oil production capacity by 25 percent. In Saudi Arabia, if there was no war or other conflict in the region, the country could control the situation after the crisis by owning foreign exchange reserves from oil; however, this country also faces serious problems to pay employees' salaries (Jefferson 2020) . As the challenges of COVID-19 on different countries were briefly reviewed above, the authors in this article intend to examine the impact of the crisis of this virus in the field of energy in Iran. As shown in Figure 4 , the main effects of COVID-19 on the energy sector in Iran include those that can be seen in the chart.

COVID-19 in the field of oil and gas energy in Iran has caused the following effects: (a) reduction of oil and petroleum product production due to delays in project Year Purpose Methods Conclusion (Chen et al. 2020) 2020 Investigation of blockchain-based e--agriculture environment

The blockchain network automatically collects and loads data through various smart devices, connects orchards and farms to an integrated network, and reviews unripe fruits intelligently Smartphones make farms smarter with blockchain technology and help agricultural projects achieve a digital farming style (Sarker et al. 2019) 2019 Addressing how big data technology contributes to digital agriculture in terms of sustainable farm management Reviewing the previous research and studies in the field of big data and the most optimal use of them This technology is used to produce livestock products, crops, fisheries, and management in the distribution of these products (Renda 2019) 2019 Providing an overview of the Internet of Things (IoT) applications in agriculture

We consider IoT-based software programs for agriculture on the market, IoT-based devices used in agriculture, and the benefits offered by these types of technologies First, an essential classification of system review studies is performed, and then the robotic process is created using artificial intelligence analysis This process can be used to ensure product quality before damage occurs (Gonzalez Viejo et al. 2019) 2019 Quality assessment of beverages in the food industry

Machine learning processes and artificial intelligence and biometric effects are some of the methods of this research

To monitor, guarantee, and control quality and standard production of beverage products implementation because of reduced required financial resources and decreased level of active human resources and consumption of commercial and industrial sectors, (b) impossibility of storing more gasoline due to reduced consumption and demand for exports, (c) decreased revenues from the sale of petroleum products due to a sharp drop in gasoline and diesel consumption in the transportation sector and reduced domestic consumption due to the semi-closure of industrial and commercial units, and (d) challenges in circumventing sanctions: as global oil demand declines and prices drop, circumventing sanctions will become more difficult because of the cost of their benefits. COVID-19 has also caused the following outcomes in the field of electricity in Iran: (a) disruption in the supply chain of equipment in the electricity industry due to a 30 to 50 percent reduction in production units' volume and forecast decrease in imports of production units (reduction of 5 to 10 percent); (b) disruption in implementing construction, maintenance, and repair projects for 3 to 6 months to perform the assigned tasks; and (c) instability of electricity generation, transmission and distribution network and occurrence of blackouts due to the lack of timely repairs and maintenance of power plants, and also the possibility of a jump in electricity demand with the resolution of the crisis, return of service, and industrial units to the electricity supply chain (see Table 5 ). Such challenges could have happened to countries similar to Iran. In the meantime, there are two vacancies: (1) cutting the dependence of government budgets and foreign exchange reserve funds on oil and gas and (2) paying attention to renewable energies, new technologies, and digital style.

As explained in the section "COVID-19 energy challenges," the oil industry has also contributed to this crisis. This issue has been accompanied by a reduction in transportation with the cessation of global air traffic and a decrease in the number of passengers and goods (www.weforum.org, 2020). The largest share of oil demand is in the transportation sector. In OECD countries, approximately 50% of this demand is considered for road transport; 8% for the aviation industry; 14% for the petrochemical industry; 9% for the residential, commercial, and agricultural sectors; and 15% for various industrial activities (Jefferson 2020) . In recent years, China has accounted for about 50 percent of world oil demand. Even the demand has declined with the outbreak of COVID-19 in this country, an energy-influential country, so that quarantine measures in the country from Wuhan and other cities reduced oil demand by 25 to 30 percent and oil prices were significantly affected. With this situation, a crisis happened in the gold market, which led to further decline due to a lack of planning to control oil energy prices.

Furthermore, in the producers of this valuable capital, namely oil, if the Middle East countries are in crisis with the outbreak of COVID-19, it can seriously affect the oil supply ). Consumption of fossil fuels directly influences phenomena such as air pollution in metropolitan areas. Meanwhile, the energy industry is complex and, at the same time, a fundamental part of economic growth in any part of the country. Providing an appropriate model to analyze energy demand and assess various factors' impact can be Fig. 4 The effects of COVID-19 on energy (oil, gas, and electricity) in Iran Environ Sci Pollut Res Statistical studies on the supply and demand in each country and the change of these parameters after the COVID-19 crisis

The study points out that due to the lack of energy demand in crisis times, a significant increase in oil prices is occurred and requires several years to overcome this challenge (Chen et al. 2020) 2020 They were investigating energy systems and their relationship with individual in-house quarantine and psychological effects among households

This study investigates the dynamics of energy use patterns, climate change issues, and social and psychological factors in a house environment through statistics analysis

This study can determine access to technologies and energy efficiency devices by considering cultural differences and comparing healthy environments in the house and family and social and psychological factors to investigate such effects with the same people's energy status (Kulachinskaya et al. 2020) 2020 They used a case study of the energy sector in the Republic of Tatarstan (Russian Federation)

The research method of this study is detailed interviews with senior managers of the energy sector

The study shows the dynamics of people's energy consumption. It considers the increase of investment in the green energy sector as a precondition for long-term development programs in the Republic of Tatarstan 2020 The analysis of the effects of COVID-19 on electricity and oil demands in China

In this study, the authors perform a regression and neural network comparison model to analyze the effects of COVID-19 on electricity and oil demand in China

This study shows that the oil and electricity demand situation concerning the population of infected people is 0.1% and 0.65%, respectively, which indicates a decrease in energy demand in both sectors. The approach of this study is to pay attention to renewable energy. Extensive surveys of China's major electrical and electronics industries in the COVID-19 outbreak have effectively reduced energy demand by decreasing or shutting down their production line capacity Su 2020a, 2020b) 2020 Investigating the effect of COVID-19 on environmental impacts in a case study in China

Statistical analysis with the support of the meteorological organization in a case study

The results show that with the advent of COVID-19 and quarantine measures and declining coal energy demand, carbon dioxide levels in Chinese air have was dropped. If this situation continues, it could significantly impact global air quality, considering that China is a significant part of its energy consumers (Vaka et al. 2020) 2020

The evaluation of the current state of renewable energy in Malaysia and the steps were taken by the country in the field of technology and photovoltaic technologies before the widespread outbreak of COVID-19

Investment information in the photovoltaic sector contained in Malaysia's in-house data and analysis of this information before and after COVID-19

From the current situation in Malaysia, it can be seen that the focus on renewable energy is directed at reducing carbon dioxide, which is not possible without the attention of the effective (www.weforum.org, 2020). Statistical methods and regression models are traditionally applied to model such cases. Recently, methods based on artificial intelligence, such as artificial neural networks (ANN) or nonlinear regression and other hybrid models, are utilized. The advantage of employing artificial neural networks is the strength of these analyses without the need for physical and technical knowledge to communicate between input and output variables. Several studies have reported better efficiency and minor error of artificial neural networks than conventional methods (Fani and Norouzi 2020; Gardner and Dorling 1998; Hagan et al. 1997; Park et al. 1991) . Another application of artificial intelligence in energy is load prediction in a future period. Based on time intervals, load forecasting can be divided into three categories: (1) long-term load forecast (next one to ten years),

(2) mid-term load forecast (1 month to 1 year), and (3) load forecast in the short term (1 h to 1 day or a week). These predictions can be used for long-term planning of power systems, efficiency, and power systems maintenance, respectively. During the epidemic, network transmission and distribution companies in China utilize big data to estimate network resumption to regulate electricity prices and reduce the cost to businesses (www.cec.org, 2020b). Artificial intelligence plays a crucial role in reducing oil production costs. It is also effective in improving oil fields and the managerial efficiency of companies. Many oil companies have commenced innovative oil field projects to improve decision-making and management . For instance, the multidimensional exploration and development platform launched by Schlumberger can achieve automated drilling design using the Internet of Things and other technologies (Nadhan et al. 2018) . In another example, AI-based intelligent management assistants, such as oil field robots, virtual oil field assistants, and intelligent oil applications, can replace humans for high-risk tasks and have higher accuracy (Tan and Potts 1995) . Based on the application of artificial intelligence in the development of oil fields. It can be concluded that this system will eventually become an intelligent ecosystem and reduce production costs and increase economic profits in cases such as exploration, production, refining, productivity, and quality management ).

Artificial intelligence is gradually entering all industries, including the energy industry. For instance, a network of big data was set up to investigate faults in power grids for faults quickly. It was used for emergency repairs based on artificial intelligence between January 25 and February 18 in China's Hubei Province at the climax of the COVID-19 outbreak. This process saves an average of 30 min on power grid repairs (www.cec.org, 2020a). Due to significant reductions in urban transportation and industrial activity, China's energy consumption was significantly reduced during the quarantine period. China is a major consumer of coal, and coal resources dominate the energy consumption structure of individuals. According to researches, coal consumption in China decreased during the COVID-19 crisis. The outbreak of COVID-19 in China has improved air quality in China and significantly impacted reducing carbon dioxide emissions Su 2020a, 2020b) . Burning fossil fuels such as coal and oil to generate electricity is one of the main causes of global warming and climate change. Many countries are profoundly dependent on fossil fuels, energy demand continues to rise, and it is expected that fossil fuel consumption will increase, resulting in further CO2 emissions. For this reason, governments around the world are encouraging people to use renewable energies (RE). RE energies are produced from abundant natural sources such as the sun, and wind; hence, they are eco-friendly resources (Vaka et al. 2020) .

As explained in the technology section in education and healthcare, applications have transformed the world into a digital world. Table 6 shows some applications in electricity and energy consumption management, and each of them provides services to users depending on their applications.

China is the world's second-largest economy and the first country to be infected with COVID-19. On the other hand, China consumes more energy worldwide. An Meanwhile, urban and rural household electricity consumption increased by 5.3 percent due to quarantine restrictions. It is noteworthy that China has had the highest growth rate among other countries for installing and equipping solar and wind power plants (Nourozi et al. 2020) . It also shows that China has taken renewable energy considerably seriously since renewable electricity is more reliable than fossil fuels. Because in case of a crisis or another disease, especially in oil-and gasproducing countries, it can lead to significant shortages in the energy sector for other countries, and China is no exception to this rule . The effects of COVID-19 have devastated a variety of industries, and solar energy is no exception. Malaysia has allocated approximately $2.9 billion in its economic aid package to install power grids and solar panels on rooftops. However, is it possible to install solar panels in any area without planning? In Heo et al.'s (2020) study, the convolution neural network model based on digital modeling is proposed to search for areas with sunlight. The annual amount of the sun in the area is examined to determine suitable locations to install solar panels. For this purpose, this method is used with the CNN approach, using datasets, including topographic information in an area to investigate the state of sunlight and model it with a nonlinear relationship between solar radiation power. Artificial intelligence is also utilized to predict power generation. AI technology is used to indicate the production 

Three styles from the perspective of the current state of the coronavirus crisis with an insight into the future can be observed in Figure 5 . Macro plans will be the final vision, and in these circumstances, the plans can be effective. Studies at COVID-19 centers such as Wuhan, Spain, and the USA reveal that air pollution is reduced by 30% during outbreaks. Cities like Delhi, India, have reported a 40 to 50 percent reduction in air pollution (Gebreslassie 2020) . Table 7 shows the significant opportunities after the COVID-19 outbreak in the renewable energy sector, explored in further articles. Satellite imagery by NASA and the European Space Agency reveals that NOX and other pollutants have dropped significantly in China, Europe, and the USA since the outbreak of COVID-19. The Chinese government issued calls in April 2020 with a subsidy policy to encourage and commercialize more electric vehicles (B. Wang et al. 2020) . Norouzi et al. (2020) provide suggestions for the future of energy in the post-corona circumstances, in which the digitization of this process is also considered. These suggestions include:

1) Development of electricity infrastructure for countries that are exposed to economic and social damage 2) The importance of paying attention to renewable electricity generation However, in COVID-19, there are reasons to pay special attention to this type of energy. Renewable sources can be used because of their reliability under challenging conditions such as COVID-19. The electricity generation sources are not flexible enough by conventional methods to control this crisis without reducing overall efficiency and putting pressure on the generation and distribution system.

Blockchain technologies are among the technologies that have created a digital lifestyle for people. It is a relatively new technology that has been introduced as a transparent, impenetrable, and secure system. COVID-19 was particularly effective in the crisis and has also affected people's health. Utility companies and energy decision-makers are very interested in blockchain technologies. Andoni et al. (2019) fully describe and examine the use and importance of blockchain. Blockchain is formally divided into eight groups according to purpose and field of activity: All of these categories can be effective, and each of them, in turn, can play a role in one part of the energy process, for example, in the first category, which is metering/billing and security. This part of the blockchain has created an opportunity for automatic billing of services and consumers' energy prices. It has also helped manufacturers reduce administrative costs and greatly facilitated communication between the customer and the energy producer, especially in the COVID-19 crisis. This technology is also effective in incentive sections related to energy and helps encourage people to reduce consumptions at peak load times (Andoni et al. 2019) .

During this period, the use of cryptocurrencies to pay for energy has attracted many people's interest. For instance, BAS Nederland, a company active in the energy industry, is the first known energy company that approved Bitcoin as a new form of energy bill payment, which was immediately followed by other companies such as Enercity of electricity bill payment. Another example is a startup company in South Africa named Bankymoon that develops technology solutions that integrate Bitcoin payments into intelligent electricity meters (Andoni et al. 2019) . Table 8 shows the significant studies on blockchain technology helpful in the COVID-19 crisis. The following are the main findings: The serious research on blockchain technology in the energy sector is rapidly expanding, indicating that blockchain energy is a developing topic of study. Also discussed are the future possibilities of blockchain technology in the energy sector, including energy storage, smart grids, energy Internet, intelligent contracts, peer-to-peer energy, renewable energy, and electric vehicles. Regarding the total number of journals, universities, highly referenced articles, and collaborative ties, a developing nation leads fundamental blockchain research in the energy sector (Wang and Yang 2021) . Most of the covered topics are based on data from researchers' data and blockchain technology and are reviewed in articles mentioned in the following.

Artificial intelligence (AI) systems have spotted an epidemic of an unknown kind of pneumonia in the People's Republic of China before the world was even aware of the danger presented by the coronavirus (COVID-19) . As a result of the outbreak's spread, it has now created a global pandemic. Policymakers, the medical community, and society at general may use AI techniques and technology to help them regulate every step of the problem and its aftermath (detection, prohibition, reply, improvement, and to speed up research). By swiftly evaluating huge amounts of research information, AI technologies and methodologies can assist policymakers and the medical society in better understanding the COVID-19 virus and accelerating research on therapies. AI text and data mining technologies can help researchers learn more about the virus's history, propagation, and diagnosis, as well as management strategies and lessons learned from prior outbreaks. To guarantee scalability and accuracy, data that is indicative of the whole population should be collected. & AI is being employed to forecast the quantity of power produced from renewable sources. As previously said, wind and solar power are very unpredictable, and AI technology can aid in predicting their generating capacity or variations in future periods in order to enhance the overall stability and security of the power system. A three-stage AI algorithm was utilized in several experiments to accurately estimate wind power output 1 h in the future. This study implements and evaluates a blockchain-based system using Ethereum smart contracts to track reported data on new morbidity, mortality, and improved cases from reputable sources

The proposed solution is economically feasible and ensures data integrity, security, and transparency in data tracking among contract holders

Since the epidemic of the novel SARS-CoV-2 virus, scientists and medical industries worldwide have been urging people to fight the pandemic by looking for alternative methods of rapid screening and prediction, contact tracing, and forecasting, and vaccine or drug development is more accurate and reliable. Artificial intelligence (AI) is a promising method that several healthcare professionals are using. The findings demonstrated that artificial intelligence enables poverty reduction by improving the collection of poverty-related data via poverty maps, modernizing agriculture education, and expanding financial inclusion in the finance sector. The survey also discovered that AI is assisting significantly in education and the banking sector, allowing previously excluded people to join the global economy. The powerful effects of the benefits of digital systems and artificial intelligence on all industries, businesses, energy, etc. were mentioned in the review of the cited articles. However, the point to be noted is the infrastructure issues of these technology models. Such technologies also come with challenges that can lead to inadequate technology transfer and utilization if not well managed. During various studies, most of these technologies face the following challenges, which can be interpreted as "basic challenges." By studying each of these factors and reviewing and developing measurement and standardization protocols and privacy laws, the challenges facing new and digital technologies can be reduced (Mbunge, 2020). As a suggestion, in the field of security risks and privacy issues, the entry of technology programs and tools into society can be made subject to a series of restrictions. In this case, legal licenses and entry of products of this group of companies into the community are possible only if it is accompanied by full compliance with regulations and actions such as the following: On economic and social inequalities, access to energy has always been an essential issue in all continents, including Africa, since only 43% of sub-Saharan Africa has access to clean and modern electricity. In these areas, there is a lack of Internet access as the driving force behind the artificial intelligence and digital industries or some areas cannot use the Internet due to communication interruptions, high costs of operators, lack of mobile phones, or the lack of electricity towers (Gebreslassie 2020; Ogunleye, Fashoto, Elliot, Arekete, & Ojewumi, 2018; Watts, 2020) . COVID-19 has largely closed people's social connections, and as explained in detail in this article, it has posed numerous challenges to energy, industries, businesses, etc. Finally, it is attempted to review the challenges of each area after COVID-19 and suggest appropriate opportunities in the same place after the crisis. Unquestionably, practical study and effort in these solutions can significantly improve the future world with new technologies.

There is no one AI approach that can reproduce or better the human mind, despite the fact that several distinct applications have surpassed similar human ability. To put it another way, we only have weak AI right now, not strong AI. These restrictions fragment the aid that technology may provide by concentrating on a pandemic. The more specialized the applications are, the less capable they are of completing a complicated and difficult task. Future studies on more sophisticated NNs, such as deep quantum NNs, may be able to overcome such issues. In addition, the ongoing COVID-19 pandemic has had various degrees of impact on stakeholders throughout the energy business value chain. COVID has had a number of consequences on the energy business, including decreased financial flows, reduced worker availability, and changes in customer behavior. As a result, using AI to anticipate energy use has become challenging.

The crisis of 2020, the COVID-19 pandemic, was similar to an uninvited guest for all communities, which caused some opportunities regardless of the problems it created. These opportunities were used in the least possible way to overcome this crisis. AI technologies are playing an essential role in fighting and controlling this epidemic. Some of the other Industry 4.0 effective in the treatment of COVID-19 were introduced in Table 1 at the beginning of the article. Undoubtedly, if this uninvited guest had traveled to different countries without these technologies, the number of cases and deaths would have been much different from the current values. The impact of these technologies and health, treatment, and disease prevention on other industries and many other fields such as energy was also associated with threats and opportunities. It is a threat because non-renewable energy, such as oil, showed a sharp decline in demand, and their index decreased with the advent of the corona, as described in the COVID-19 Challenges on Energy. Different countries, including Iran as an OPEC member and an influential member of the energy sector, were involved in dealing with this crisis. COVID-19 caused some opportunities since many new businesses were set up in the same environment, and many more were accompanied by increased growth and profitability, including clean and renewable energy technologies. With the outbreak of COVID-19 and the quarantine period, many people were motivated to think about using renewable energies.

On the other hand, other technologies related to renewable energy and artificial intelligence were also accompanied by growth as an example of health-oriented applications, disease tracking, and energy consumption management applications. These are also valuable and practical depending on the needs of people in the community. They also increase the motivation to enter this field in various disciplines, such as programming this technology style and teaching this technology to younger generations. In addition to affecting the people, the COVID-19 crisis has been accompanied by threats and opportunities for governments and countries that already recognized the importance of paying attention to new technologies and renewable energy faced with fewer economic and subsistence problems and crises in energy production and distribution. However, countries that desired to pay direct attention to non-renewable energy and the profits from that energy to run their economies faced extensive difficulties that may cause significant damage to the same countries in the event of another crisis similar to COVID-19.

The COVID-19 crisis has affected businesses, technologies, energy, etc., and this impact will be continued. It also influences the oil sector by the OPEC member countries on the oil value index. The challenges of COVID-19 are solved in all areas only by paying attention to new technologies, renewable energy, and artificial intelligence. Then this can be noted that the only condition for having a safe, healthy, dynamic, and economically positive society is to have a digital lifestyle since we may face several other crises in the future. Houses will be the only safe and healthy places at that time. We must think regarding which before the problem occurs. Future research should take numerous paths: new prospects in AI have continually emerged as a result of unique needs, energy efficiency, and savings, as well as reducing and eliminating the environmental load produced by electricity production, transmission, and distribution. It is possible to discuss sustainable energy options and their implications for energy in the event of a future pandemic.
