Question 41

A prominent housing developer plans construction of a small low-carbon-emitting city in an equatorial nation. The developer plans to maximize renewable energy use and estimates daily city summer solar energy generation capacity and load (total electricity demand), in megawatts (MW):

The developer estimates the following for capacity and load:

At 14:00 solar generation is highest at 720 MW

At 20:00 solar generation decreases to 0 MW

At 20:00 load is highest at 980 MW

At 4:00 load is lowest at 380 MW

How should the developer meet additional energy demand while achieving the lowest-carbon-emission goal option?

    Correct Answer: A

    To meet the additional energy demand while achieving the lowest-carbon-emission goal, increasing solar capacity by 800 MW and installing 200 MW of battery storage is the best option. This approach maximizes the use of renewable solar energy, and the batteries will store excess power generated during peak solar hours for use during non-solar hours. This method directly addresses the city's energy needs and leverages renewable resources effectively, reducing reliance on carbon-emitting energy sources.

Discussion
Gs2410Option: D

key point is equatorial nation. wind energy is the best alternate renewable solution

CecileCOption: A

Correct answer is A.

KarnitschnigOption: A

Wind is intermittent too, not a good fix for the problem. And the numbers don't make sense. Batteries do for this case. Poor question
