Greenhouse Gas Emissions Reduction through Integration of Renewable and Non-renewable Energy Sources: A Model for Sangan Iron Ore Mine Complex of Iran

The iron ore mining industry is a crucial component of the global economy, yet it is one of the most energy-intensive sectors, heavily reliant on non-renewable energy sources. This industry contributes approximately ۷% of global CO۲ emissions, leading to significant environmental pollution and economic instability. Switching to renewable energy is crucial for reducing climate change and its impacts on health. This research focuses on optimizing its use alongside non-renewable energy sources to minimize the carbon footprint and promote socio-economic development in the region. The study reveals that the Sangan complex has exceptional weather conditions for harnessing solar and wind energy. Feasibility analyses indicate that a ۱۰۰ MW solar power plant and a ۱۰ MW wind power plant could supply ۴۰% and ۱۶% of the complex's electricity needs, respectively. Transitioning from complete reliance on non-renewable energy sources—resulting in annual GHG emissions of ۳۴۹,۲۲۹ tons—to a model where ۵۶% of electricity comes from renewable sources could reduce emissions to ۸۸,۷۵۷ tons per year. The initial investment for establishing solar and wind power plants is estimated at USD ۹۹ million and USD ۵۰ million, respectively, with annual maintenance costs of USD ۸۲۵,۰۰۰ and USD ۱.۵ million. Importantly, this model not only demonstrates economic viability but also offers substantial financial justification through lower operational costs. Developing renewable energy sources at Sangan creates job opportunities, fosters entrepreneurship, and enhances economic resilience. This approach optimizes energy production, contributes to environmental goals, and supports a sustainable future in Iran's mining sector.
