What is BEY 002 Question Paper December 2025 Definition
The BEY-002 December 2025 question paper is the official IGNOU Term End Examination paper for Energy Resources, conducted in December 2025 for BSCAEY students. It carries 70 marks, runs for three hours, and asks you to attempt any seven questions of equal marks, each worth 10 marks.
The paper tests how well you understand both conventional and non conventional energy sources. Questions move from fossil fuel reserves and nuclear basics to renewable topics like solar, wind, biogas and tidal energy. You are expected to handle theory, comparisons, instrument construction, and a Betz law derivation with equal confidence in the exam.
About IGNOU BEY-002 Energy Resources
BEY 002 is a core paper in the IGNOU BSCAEY programme. It gives you a full view of energy sources used in India and the world. The course covers conventional fuels like coal, oil, natural gas and nuclear energy, along with renewable sources such as solar, wind, biomass, biogas and tidal energy. It also covers measurement instruments like the pyrheliometer and applications like photovoltaics and solar cookers. Students who link each topic to Indian projects and real plants tend to score better.
BEY 002 Question Paper December 2025 Exam Pattern and Marks Breakdown (BEY-002 December 2025 Question Paper)

BEY 002 Question Paper December 2025 Syllabus Topics Covered
The paper maps cleanly to the BEY 002 syllabus. You see the Indian energy scenario, including oil, coal and natural gas reserves. Coal specific topics like coalification, rank and grade are tested directly. LPG and CNG comparison covers the petroleum and gas side. Nuclear energy is checked through control rods, materials and design. Renewable sources are covered through pyrheliometer, photovoltaic applications, Betz law for wind, biogas properties, tidal energy, bio energy and solar cooker. This gives a full sweep of the course.

Take Question 7 on Betz's law. A weak answer just states the 59.3 percent figure. A scoring answer draws the wind turbine stream tube, applies continuity and momentum equations, defines the axial induction factor a, expresses power P as a function of a, and finds maximum P by differentiation at a equals one third. It concludes with the Betz limit of sixteen by twenty seven, about 59.3 percent. Our solved paper walks through each step with clear symbols and diagrams.
How to Write High-Scoring Answers in BEY 002 Question Paper December 2025
Start each 10 mark answer with a short definition or opening paragraph. For comparison questions, like LPG versus CNG, use a clear side by side structure covering composition, pressure, storage, calorific value, safety and uses. For derivations, show assumptions, figure, equations, step by step algebra and final result, because BSCAEY examiners reward method. Use neat sketches for pyrheliometer, solar cooker and wind turbine. Add one Indian example, like Mumbai High for oil or Jaisalmer for wind. End with a short conclusion.
Who Should Use This BEY-002 Solved Question Paper December 2025?
This solved paper is made for IGNOU BSCAEY students appearing in June 2026, December 2026 or later Term End cycles. It also helps reappear candidates, backlog students clearing BEY 002, and working professionals from oil and gas, coal, nuclear, solar, wind and biogas companies who have joined BSCAEY as a career skill. If you are balancing shift duty, family and studies, this paper gives you a focused, time saving way to revise without reopening every unit of the course book.
Why This is Better Than Free BEY-002 December 2025 Question Paper PDFs and Telegram Files
Free PDFs on Telegram and random blog sites often have wrong Betz law derivation, missing units, or theory that does not match IGNOU BSCAEY style. Some files skip the control rods question entirely. Others give two lines for a 10 mark comparison between LPG and CNG, which will clearly not score. Our solved paper is written by a subject expert, checked against the official December 2025 paper, and formatted in proper engineering answer style. You save preparation time, protect your marks, and revise with real confidence.
Student Reviews BEY-002 Solved Question Paper by Unnati Education
Akash from Ahmedabad, working in a CNG distribution firm, said the LPG versus CNG answer matched exactly what he sees in field operations every week. Swati from Bhopal told us the Betz law derivation finally made wind energy calculations feel doable in a timed exam. Tariq, a first time BSCAEY learner from Guwahati, wrote that the biogas properties answer was the clearest explanation he had read online during his full preparation cycle for this particular paper.

Will this paper help me for my 2026 exam?
It will help you strongly. IGNOU often repeats question themes in BEY 002, especially on Indian fossil fuel reserves, LPG versus CNG, nuclear control rods, pyrheliometer, photovoltaic applications and Betz law. By practicing the December 2025 paper with solved answers, you understand the examiner style, the expected length for a 10 mark question, and how to structure both theory answers and derivations for full marks in your Term End exam.
Is the Betz law derivation fully shown?
Yes. Question 7 on Betz law is derived step by step in the solved PDF. We start from the stream tube assumption, apply continuity and momentum equations, define the axial induction factor, express power in terms of this factor, and then differentiate to find the maximum value. The solution ends with the Betz limit of about 59.3 percent. Every step is explained in clear language, so even if wind energy looks tough, the method becomes easy.
Can I use this for my BEY 002 assignment too?
You can use it as a strong reference while writing your BEY 002 assignment, especially on topics like Indian energy reserves, coalification, LPG and CNG, pyrheliometer and biogas properties.
