While researching a topic, a student has taken the following notes:
- The Wayang Windu geothermal power plant in Indonesia uses a flash steam system to generate electricity.
- Flash steam technology requires geothermal reservoir temperatures above
.
- The use of flash steam systems worldwide is limited because many geothermal reservoirs aren't hot enough.
- The Raft River geothermal power plant in Idaho uses a binary cycle system.
- Binary cycle technology can generate energy from lower-temperature (less than
) geothermal reservoirs.
- Binary cycle systems involve higher maintenance costs than flash steam systems.
The student wants to compare the disadvantages of the geothermal systems used at the Wayang Windu and Raft River plants. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Compared with the system used at the Wayang Windu plant, the system used at the Raft River plant has a notable disadvantage: its cost.
A
Unlike the Raft River plant, the Wayang Windu plant uses a flash steam system, which requires a less common resource: geothermal reservoirs with temperatures above .
B
The system used at the Raft River plant overcomes the temperature limitations of the Wayang Windu plant's system but is more costly to maintain.
C
The system at the Wayang Windu plant requires temperatures above while the system at the Raft River plant can operate at lower temperatures.
D
