| 2011 | 50 | 20 | 10 | 40 | 60 | 15 | 08 | 50 |
| 2021 | 60 | 28 | 15 | 42 | 68 | 20 | 10 | 55 |
In which state and for what type of energy source of electricity, the percentage decadal growth (%) in installed capacity was maximum?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept used:
Percentage growth = ((New capacity - Old capacity) / Old capacity) × 100
Calculation:
For State X:
⇒ Solar: Percentage growth =
⇒ Wind: Percentage growth =
⇒ Coal: Percentage growth =
For State Y:
⇒ Solar: Percentage growth =
⇒ Wind: Percentage growth =
⇒ Coal: Percentage growth =
The maximum percentage decadal growth is 50% for Wind energy in State X.
∴ The maximum percentage decadal growth in installed capacity of electricity was for Wind energy in State X.
