Abstract
With the spread of environmental pollution, environmental recovery has turned into a critical goal of governments. Energy efficiency and the use of renewable energy are two essential solutions to control the emission of greenhouse gases. However, the research on these effective tools in reducing greenhouse gas emissions at macro and systemic levels in the power sector is insufficient. The present research uses the comprehensive approach of system dynamics to investigate these policies for reducing CO2 emissions in Iran’s electricity generation sector. The results show that both policies are effective in improving the country’s energy security, but the impact of the renewable development policy in reducing carbon emissions is more prominent. Furthermore, the results showed that by implementing the photovoltaic development policy, access to the 21% share of this sector of the entire Iranian electricity sector can be realized by the end of 2033. Also, improving the efficiency of thermal power plants by up to about 3.5% can be achieved by implementing the policy of increasing efficiency.
期刊介绍:
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
