In terms of their contribution to India’s installed power-generation capacity around the July 2018 UGC NET examination, identify the correct descending sequence of these energy sources: Thermal Power Plants (TPP), Large Hydropower Projects (LHP), Nuclear Energy (NE), and Renewable Energy (RE), where RE includes solar energy, wind energy, biomass, and small hydropower projects.

LHP > TPP > RE > NE
- D.
LHP > TPP > NE > RE
Show answer & explanation
Correct answer: A
Concept
Installed power-generation capacity is the maximum rated output that generating assets can supply, usually measured in megawatts (MW). To rank source groups, compare their installed capacities on the same reference date.
Installed capacity is different from the electrical energy actually generated during a year; a capacity-ranking question must use MW capacity values rather than annual generation in million units.
Application
Use the official capacity snapshot near the July 2018 examination and keep large hydropower separate from the stated renewable-energy group.
The reported capacities were approximately 221,803 MW for thermal power, 70,648 MW for renewable energy, 45,487 MW for large hydropower, and 6,780 MW for nuclear power.
Sorting these values from greatest to least gives TPP > RE > LHP > NE.
Cross-check and contrast
The adjacent comparisons are 221,803 > 70,648 > 45,487 > 6,780, so every inequality in TPP > RE > LHP > NE follows from the same capacity snapshot.
TPP > LHP > RE > NE reverses renewable energy and large hydropower; 70,648 MW is greater than 45,487 MW.
LHP > TPP > RE > NE places large hydropower ahead of thermal power, although thermal capacity was nearly five times as large.
LHP > TPP > NE > RE also places large hydropower ahead of thermal power and reverses renewable and nuclear capacity.
Therefore, the correct descending sequence is TPP > RE > LHP > NE. This is also the sequence selected by CBSE’s final answer key for the July 2018 UGC NET Paper I item.
