This question paper evaluates a student’s understanding of fundamental and applied concepts of Energy Science & Engineering, covering topics from heat energy, nuclear processes, solar energy, geothermal systems, energy storage, climate science, and renewable energy technologies. The paper is designed to measure conceptual clarity, analytical ability, and problem-solving skills related to modern energy systems.
The paper is divided into three structured sections, ensuring a balanced assessment of definitions, short theoretical explanations, and long, analytical answers requiring in-depth understanding.
SECTION A – Conceptual Understanding (14 Marks)
In this section, students must answer seven short questions, each testing fundamental definitions and basic concepts.
Topics include:
Heat energy and its significance
Nuclear fission vs nuclear fusion
Advantages of nuclear energy
Solar radiation and solar cell types
Applications of geothermal energy
Meaning and importance of energy storage
These questions check the student’s grasp of essential terms that form the foundation of the subject.
SECTION B – Analytical & Descriptive Questions (21 Marks)
Students must attempt any three out of five detailed questions.
This section requires deeper explanation, diagrams where needed, and proper reasoning.
Topics covered include:
Quantum theory and energy quantization
Nuclear binding energy and its reactions
Semiconductor materials and PN-junction V-I characteristics
Different geothermal systems (dry steam, wet steam, hot water) with diagrams
Climate change and energy conservation explained in detail
This section tests the ability to apply concepts, explain processes, and connect theory to practical applications in energy systems.
SECTION C – Application-Based Long Questions (21 Marks)
Students must attempt one question from each of the three parts (3 questions total).
This section demands greater depth and structured answers.
Key areas include:
Steam and gas power cycle principles
Entropy, phase change energy, and electromagnetic energy concepts
Nuclear fission reactor design and energy scales
Solar PV system limitations, building-integrated photovoltaics, and P–V characteristics
Different generations of solar cell technology
Closed-cycle OTEC (Ocean Thermal Energy Conversion) principles and limitations
Wind energy conversion methods and strategies to control power fluctuation
Energy audit, energy optimization, LEED ratings, and green building concepts
This part of the exam assesses a student’s real-world understanding, engineering reasoning, and ability to present technical content logically.
Overall Purpose of the Paper
The question paper is structured to ensure that by the end of the course, students can:
Understand and explain major energy conversion systems
Compare renewable and non-renewable energy technologies
Analyze performance characteristics of nuclear, solar, geothermal, wind, and OTEC systems
Apply scientific principles to energy storage, optimization, and sustainability
Explain modern energy engineering practices such as green buildings, energy audits, and climate impact
