A faculty member from the Chemistry Department publishes a scientific article on the role of renewable energy in building a sustainable future.
Dr. Adel Abbas Karim, a lecturer in the Chemistry Department, published a scientific article titled “The Role of Renewable Energy in Building a Sustainable Future: From Theory to Application.”
The article addresses the shift from renewable energy and its evolving applications to a strategic, economic, social, and environmental necessity. It has moved from the realm of theoretical academic research to tangible, practical scientific application, experiencing rapid growth worldwide. Building a sustainable future requires redoubling efforts to overcome technical and financial challenges, strengthening international cooperation, and developing supportive and ambitious policies.
Investing in renewable energy today is an investment in the health of our planet, the prosperity of our economies, and achieving social justice for current and future generations. It is the inevitable transition from the fossil fuel era to the era of clean energy, and the last chance to ensure a secure and sustainable future for all of humanity.
From this perspective, sustainable development emerged as a philosophy and methodology aimed at meeting the needs of the present without compromising the ability of future generations to meet their own needs. At the heart of this vision stands renewable energy, not merely as an energy alternative, but as a cornerstone in building a sustainable future that blends environmental protection with economic prosperity and social justice.
This article moves from the theoretical foundations of renewable energy to its practical applications, highlighting its achievements and challenges. The foundations of renewable energy are based on:
1. Renewable Energy: Scientifically speaking, renewable energy is energy derived from natural resources that are replenished at a rate faster than they are consumed. Renewable energy sources are inexhaustible. Among the most important types are:
• Solar Energy: Converting sunlight and its heat directly into electricity using photovoltaic cells or for heating water and air.
• Wind Energy: Using wind turbines to convert the kinetic energy of the wind into mechanical energy, and then into electricity.
• Biomass energy: Utilizing the energy stored in organic materials (agricultural waste, wood, biogas) through direct combustion or thermal and chemical conversion.
• Hydroelectric power: Generating electricity from the kinetic energy of water, whether in large dams or from natural river flows (small turbines).
• Geothermal energy: Using heat stored underground to generate electricity or for direct heating.
2. Theoretical Framework for Sustainability: Renewable energy is directly linked to the three dimensions of sustainability:
• Environmental dimension: Renewable energy is the ideal solution for reducing the carbon footprint. It does not produce direct greenhouse gas emissions during operation, thus contributing significantly to mitigating the effects of climate change.
• Economic dimension: In the long term, renewable energy is a catalyst for economic growth. It reduces countries’ dependence on fossil fuel imports, improving their energy security and trade balance. • Social dimension: Renewable energy, especially in its decentralized and small-scale systems, enables remote and rural communities to access clean electricity, improving their quality of life and supporting education (through lighting and powering electrical appliances), healthcare, and livelihood opportunities. This promotes energy equity and reduces the gap between communities.
