If you are going to give GATE 2026 this year, there is a new paper that has been introduced, and that is Energy Science (XE-I) under the Engineering Sciences (XE) section.
Since Energy Science has been included by GATE 2026 as a subject, you might be interested in knowing about its pattern of examination, syllabus and preparation.
The GATE 2026 Energy Science (XE-I) exam pattern will be the same as the other GATE papers and will have two sections:
- General Aptitude (GA) - common to all papers, carrying 15 marks.
- Energy Science Core Section - subject-specific questions carrying the remaining 85 marks.
The GATE Energy Science syllabus covers topics such as renewable energy systems, energy conversion and thermodynamics, electrical machines & power electronics, energy storage technologies, policy & economics and instrumentation/control systems.

Key Summary
- Energy Science (XE-I) has been introduced under the Engineering Sciences (XE) paper, alongside existing options like Fluid Mechanics, Thermodynamics and Materials Science.
- The paper includes General Aptitude (15 marks), Engineering Mathematics (15 marks) and two optional subjects (70 marks), with Energy Science now available as one of the optional sections.
- Since XE-I is new, the expected qualifying cutoff is projected at 25-30 marks for the General category, and it is especially relevant for admissions to IITs/NITs offering Energy & Sustainability programs.

GATE Energy Science Question Paper FAQs
Ques. This is the first time Energy Science (XE-I) has been introduced. Is it a good idea to take a brand-new subject for GATE 2026?
Ans. Yes, it can be a smart choice if you have an interest in renewable energy, energy systems, or policy. Since it’s new, competition might be slightly lower, but at the same time, cut-offs and demand are unpredictable. If you’re aiming for M.Tech/Ph.D. in Energy Studies or Sustainability, this could be a very relevant option.
Ques. What is the exam pattern for the XE papers and how does XE-I (Energy Science) fit into it?
Ans. In GATE XE papers, you have three parts:
- General Aptitude (15 marks)
- Engineering Mathematics (15 marks)
- Two subject sections of your choice (2 × 35 = 70 marks)
Energy Science is listed as XE-I, so you can choose it as one of your two optional sections.
Ques. Since Energy Science is new, what could be the qualifying cutoff for GATE 2026?
Ans. There’s no past data, but looking at trends from new subjects (like Humanities in 2021), the General category cutoff may hover around 25-30 marks out of 100. However, the final cutoff for IIT admissions could be higher depending on how many students opt for XE-I.
Ques. Are there IITs or NITs that already offer Energy Science or related programs where this paper will be useful?
Ans. Yes. For example:
- IIT Bombay - Department of Energy Science & Engineering
- IIT Delhi - Centre for Energy Studies
- IIT Madras - Energy Systems
- NIT Trichy, NIT Calicut and NIT Bhopal - Renewable & Sustainable Energy programs
So, XE-I will likely open doors in these interdisciplinary departments.
Ques. I’m confused between giving my core paper (like Mechanical) vs. this new Energy Science section. What’s your advice?
Ans. If your goal is PSU jobs, stick to your core paper (ME, EE, EC, etc.) since PSUs usually recruit through those. But if your long-term goal is research, academia, or green energy industries, XE-I could be a niche advantage. It depends on whether you want breadth (core) or specialisation (energy focus).
Ques. Apart from XE-I, what are the other new changes in GATE 2026?
Ans. Apart from Energy Science being added, IIT Guwahati (the organising institute) has also updated a few syllabus sections across Mechanical, Civil and Computer Science. Also, the exam will now have more virtual calculator practice and mock tests available on the official portal.
Ques. I’m from a Civil Engineering background. Can I choose XE-I as one of my optional sections?
Ans. Yes, absolutely. Any engineering graduate can opt for XE papers. In fact, for Civil engineers, topics like hydropower, environmental impacts and energy policy are directly relevant. Many interdisciplinary M.Tech programs don’t restrict based on your UG branch, as long as your GATE paper aligns with the course.
Ques. How should I prepare for XE-I since no previous years’ papers are available?
Ans. One can follow the steps:
- Start with the official sample paper provided on the GATE 2026 portal.
- Use NPTEL courses on “Energy Science and Technology” and “Renewable Energy Engineering.”
- Refer to books like Energy Science: Principles, Technologies and Impacts by John Andrews & Nick Jelley.
- Solve practice problems from related Mechanical/Electrical subjects (Thermodynamics, Power Systems, Heat Transfer).
