Covid-19 has changed tourism significantly. Numerous research shows how various factors will affect travel after COVID-19. No doubt that tourism has become a major global industry with an annual average growth rate of 4-5%. It also creates 8% of the global GDP and 10% of employment. Yet it is also very vulnerable to crises of different origin such as natural disasters, epidemics, economic crises, political crises, terror, etc. Because tourism product (e.g. hotel beds, airline seats, restaurant tables, guide services) is perishable, unlike physical goods, they cannot be stored for future use. Past crises with few exceptions (e.g. 2008 Financial Crisis, 2014 Financial Crisis, the terroristic attack of airplane in Cairo 31st of October, 2015) had regional impacts and their global impact on tourism volume was limited. Yet, taking into account the speed and impact, Covid-19 is the most serious crises tourism industry has ever faced. This crisis is estimated to have a seven time larger impact on tourism than the 2008 Financial Crises. The effects of Covid-19 are expected to extend for two years and result in a decrease of 39-50% in global tourism volume. Tourism industry is expected to recover to 2019 pre-crises levels not before 2023.

Moving towards RER has become imperative to achieve sustainable development goals (SDG). Renewable energy resources (RER) are characterized by uncertainty whereas, most of them are unpredictable and variable according to climatic conditions. This paper focuses on RER-based electrical power plants as a base to achieve two different goals, SDG7 (obtaining reasonably priced clean energy) and SDG13 (reducing climate change). These goals in turn would support other environmental, social, and economic SDG. This study is constructed based on two pillars which are technological developments and life cycle assessment (LCA) for wind, solar, biomass, and geothermal power plants. To support the study and achieve the main point, many essential topics are presented in brief such as fossil fuels’ environmental impact, economic sustainability linkage to RER, the current contribution of RER in energy consumption worldwide and barriers and environmental effects of RER under consideration. As a result, solar and wind energy lead the RER electricity market with major contributions of 27.7% and 26.92%, respectively, biomass and geothermal are still of negligible contributions at 4.68% and 0.5%, respectively, offshore HAWT dominated other WT techniques, silicon-based PV cells dominated other solar PV technologies with 27% efficiency, combustion thermochemical energy conversion process dominated other biomass energy systems techniques, due to many concerns geothermal energy system is not preferable. Many emerging technologies need to receive more public attention, intensive research, financial support, and governmental facilities including effective policies and data availability.

The intermittent nature of photovoltaic energy necessitates the incorporation of storage devices to ensure the continuality of loads feeding. In addition, it is important to model, control, and verify the operating of the designed system before implementation. Furthermore, the integration of power electronic interfaces plays a significant role in protecting the system and benefiting from solar energy. To this end, a buck converter is chosen to charge the battery and supply the supercapacitor. The control strategy is based on the maximum power point tracking techniques when the management algorithm recommends MPPT function mode. Otherwise, a feedback constant voltage PI controller is designed. Indeed, perturb and observe and incremental conductance are implemented and compared to analyze the system efficiency within the management strategy to charge the battery, switch between the controllers, and feed a supercapacitor in case of full battery charge. The obtained results using MATLAB/SIMULINK platform confirm the behaviour of the proposed strategy.
