While researching a topic, a student has taken the following notes:
- The Nga Awa Purua geothermal power plant in New Zealand 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 Beowawe geothermal power plant in Nevada 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 Nga Awa Purua and Beowawe plants. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Compared with the system used at the Nga Awa Purua plant, the system used at the Beowawe plant has a notable disadvantage: its cost.
A
The system at the Nga Awa Purua plant requires temperatures above , while the system at the Beowawe plant can operate at lower temperatures.
B
Unlike the Beowawe plant, the Nga Awa Purua plant uses a flash steam system, which requires a less common resource: geothermal reservoirs with temperatures above .
C
The system used at the Beowawe plant overcomes the temperature limitations of the Nga Awa Purua plant's system but is more costly to maintain.
D
