Geothermal Energy MCQs : This section focuses on the "Geothermal Energy" in Renewable Energy. These Multiple Choice Questions (MCQs) should be practiced to improve the Renewable Energy skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
___________ energy refers to heat energy stored under the ground for millions of years through the earth formation.
Explanation: Geothermal energy refers to heat energy stored under the ground for millions of years through the earth formation. It utilizes a rich storage of unutilized thermal energy that exists under the earth’s crust.
There exists a huge temperature difference between the earths crust and the surface, the temperature difference is known as?
A. temperature gradient
B. geothermal difference
C. geothermal gradient
D. None of the above
Explanation: There exists a huge temperature difference between the earths crust and the surface. The temperature difference is known as geothermal gradient.
Which of the following advantages of Geothermal Energy?
A. Geothermal energy is relatively less expensive
B. It has no emissions and produces 10% carbon dioxide
C. No fuel is burnt since heat is derived from an abundant underground reservoir
D. All of the above
Explanation: All of the above are Advantages of Geothermal Energy.
EGS stands for?
A. Enhanced Geothermal Sink
B. Expend Geothermal Sources
C. Enhanced Geothermal Sources
D. Emission Geothermal Sources
Explanation: EGS stands for Enhanced Geothermal Sources.
Geothermal energy utilizes high temperatures below the earths crust.
C. Can be true or false
D. Can not say
Explanation: True, Geothermal energy utilizes high temperatures below the earth’s crust.

Which of the following organisations deals with geothermal energy locations in India?
A. Geological Society of India
B. Forestry Department
C. Ministry of external affairs
D. Geological Survey of India
Explanation: Geological Survey of India (GSI) is the government organisations that deals with various geothermal energy locations in India. It was founded in 1851 and works under the Ministry of Mines Organisation. It is the second oldest survey in India after Survey of India.
What is the estimated potential for geothermal energy in India?
Explanation: The exploration and study of geothermal fields in India started in 1970. The estimated potential for geothermal energy in India is 10000MW. Amongst all the other locations, Puga valley is the most promising one.
What are the forms of geothermal energy?
A. Liquid and solid
B. Liquid and vapour
C. Solid and Bose-Einstein condensate
D. Plasma and liquid
Explanation: Geothermal energy either comes in liquid form or in vapour form. They are not solids. Bose-Einstein condensate and plasma are not forms of geothermal energy. They are states of matter.
