| Author | Year | Purpose | Method | Conclusion |
|---|---|---|---|---|
| (Gebreslassie 2020) | 2020 | Achieving the sustainable development goals in Africa to take full advantage of the opportunities created by the COVID-19 crisis | Develop and implement the proposed guidelines for renewable energy | The policies in this article help the African continent facilitate access to power and achieve sustainable development |
| (Klemeš et al. 2020) | 2020 | Investigation of waste disposal problems in medical and health centers under the COVID-19 virus | Providing six proposals for the disposal of plastic waste in the future after the COVID-19 crisis | Changes in waste management practices |
| (Vanapalli et al. 2021) | 2021 | We are using the disposal of waste in medical centers in the conditions of the virus with an artificial intelligence style | Integration of new sustainable technologies in the current waste management system | Developing dynamic waste management without the intervention of human labor by artificial intelligence |
| (Jefferson 2020) | 2020 | Improving oil prices and energy indicators in the years after COVID-19 | 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 |
| (Norouzi et al. 2020) | 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 |
| (Wang and 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 government and incentive plans for people in the community |
| (Eroğlu 2020) | 2020 | Investigating future studies by environmental and renewable energy researchers considering conditions such as COVID-19 | Statistical reviews and analysis of the energy and environmental data | Lack of awareness and government training, technical and investment support in the renewable energy sector, and investors’ entry in this sector have faced a severe challenge. By learning from this crisis, prior mistakes should be corrected |
