Geothermal Engineer

Geothermal engineers use heat from deep inside the earth to produce power and heating. In India this is a small, emerging field with no dedicated degree.

Class 11–12 subjectsPhysics, Chemistry, Maths

Your route, step by step

1Class 11–12: take PCMThermodynamics in Physics and an interest in geology are the base for this niche field.
2Write the entrance examsJEE Main for NITs and many colleges, JEE Advanced for IITs. In Tamil Nadu, TNEA counselling uses your Class 12 marks.
3B.E. / B.Tech Mechanical, Petroleum or Chemical · 4 yearsOr study geology — the skills overlap with oil-and-gas drilling.
4SpecialiseM.Tech in energy or geothermal-related programmes, often abroad.
