Question Details

A state electricity report serves as an important tool to assess energy production and track progress in the power sector. By providing quarterly data on generation measured in gigawatt hours (GWh), the report highlights the contribution of different energy sources such as coal, gas, hydro, solar, and wind. This not only helps in understanding the overall energy mix and dependence on conventional versus renewable sources but also enables policymakers, planners, and stakeholders to evaluate trends, address gaps, and promote sustainable energy development. A state electricity report provides quarterly generation (in GWh) by source – Coal, Gas, Hydro, Solar, and Wind.


In Q1 Generation from Coal is 2,200 GWh, Gas contributes 800 GWh, Hydro 900 GWh, Solar 700 GWh, and Wind 400 GWh, for a total of 5,000 GWh.


In Q2 Coal rises to 2,400 GWh, while Gas dips to 700 GWh; Hydro improves to 1,000 GWh, Solar to 800 GWh, and Wind to 600 GWh, bringing the quarterly total to 5,500 GWh.


In Q3 Coal moderates to 2,100 GWh, Gas increases to 900 GWh, Hydro softens to 800 GWh, but Solar advances to 1,000 GWh and Wind to 700 GWh, keeping the total at 5,500 GWh.


In Q4 Coal moves to 2,300 GWh, Gas to 850 GWh, Hydro to 1,100 GWh, Solar to 900 GWh, and Wind to 850 GWh, for a total of 6,000 GWh.


For analysis, Renewables are taken as Hydro + Solar + Wind. A carbon policy scenario proposes cutting Q4 Coal by 10%, shifting the entire reduction equally into Solar and Wind. (255 words)


The total annual generation (GWh) is :

Options

A

20,500

B

21,500

C

22,000

D

22,500

Show Answer

Correct Answer :

Option C

22,000

Solution :

The correct option is 22,000.


To find the total annual generation, we sum the total power generation across all four quarters (Q1, Q2, Q3, and Q4).


From the given data, the total generation for each quarter is as follows:

• Total generation in Q1 = 5,000 GWh

• Total generation in Q2 = 5,500 GWh

• Total generation in Q3 = 5,500 GWh

• Total generation in Q4 = 6,000 GWh


Now, calculate the total annual generation by adding these quarterly totals together:

Total Annual Generation=5,000+5,500+5,500+6,000


Total Annual Generation=22,000 GWh


Therefore, the total annual generation is 22,000 GWh.
