“…The word nexus was used in the United Nations in 1980s for the first time. This principle has been developed in 2011 for promoting the inseparable nexus between using the resources for ensuring the fundamental and universal rights of water, food, and energy security and supporting the transition to a green economy and in 2015 this principle has been considered as the most appropriate approach for evaluating the challenges and opportunities of sustainable development in 2015 16 . Today, nexus attitude is one of the sciences of grand and comprehensive resource management which processes and provides strategic solutions for the challenges of sustainable development in the human society.…”

The challenge of providing water, energy, and managing the environment is widely recognized as a significant barrier to global advancement in light of the increasing population. Based on projections, it is anticipated that the global community will encounter crises pertaining to water, energy and the environment in the foreseeable future. In this research, the application of the hybrid renewable system in a thermal power plant has been assessed based on the approach of analyzing the link between energy, water, and environment. The design of the solar system and the assessment of carbon balance during the power plant lifetime have been conducted in PVsyst application in 2022. Moreover, ReCipe environmental model has been used for assessing the effect of decrease in carbon emission on the ecosystem. The findings of the research indicate that the replacement of at least 2% of the nominal capacity of the fossil fuel power plant with the renewable one, prevents the emission of 1340.37 tons of carbon dioxide yearly. This amount equals to 371.25 m3 of reserve in fossil fuel consumption and 382.64 tons of crude oil. The results also showed that in addition to preserving natural resources, the hybrid cycle design leads to significant water demand reduction which equals to 3751 m3 with the capacity to supply underground water sources. Due to the interests of preserving water and energy resources and decreasing carbon emission in power plant industry, within the framework of nexus approach, management of energy supply by replacing resources and using water and heat recovery technologies and application of energy demand management policies based on energy efficiency and environmental implications is recommended.

Along with the main objective of politicians, other economic variables are variously affected by the environmental taxes, policies, and limitations like a price on pollution, clean electricity, the cap on emissions, methane emissions, and nature‐based solutions. The objective of the environmental solutions is to decrease pollutant emissions and energy consumption while reducing labor costs and taxes as the incentives for creating new occupations. An overall equilibrium model was considered in the present study as a nonlinear equations system, which was calibrated for the reference year of 2018 utilizing Canada's economy's data table. The effects of utilizing these environmental policies considered by Canada in COP26 are examined. In all scenarios, minimum, maximum, and optimum values for reducing pollutant emissions are calculated under these policies. According to the simulation results, welfare is reduced by the price of pollution policy. Moreover, the actual consumed budget of the household is reduced by 8%. However, such indices will be incremented by 2% in the nature‐based policy. In all scenarios, the gross domestic product is decreased. However, in the methane emission policy, this reduction is 1.05% in the lowest state. In all scenarios, the consumer price index will be incremented by 3.8%–9.8%. It is concluded that the clean electricity policy is an appropriate policy for reducing greenhouse gas emissions and at the same time adhering to international commitments.
