Question

which of the following best describes a disadvantage of geothermal energy production?
a geothermal energy production is a significant source of noise pollution.
b geothermal energy implementation in homes and businesses has a high upfront cost, and electricity is needed to operate pumps.
c geothermal energy generation costs remain stable when gas and oil prices increase.
d geothermal energy is weather dependent and can be generated only at certain times of the year.

Explanation:

• Option A: Geothermal energy production is not a significant source of noise pollution.
• Option B: Geothermal energy implementation in homes and businesses has a high upfront cost (for installing the system), and electricity is needed to operate pumps (to circulate the fluid in the geothermal loop). This is a valid disadvantage.
• Option C: Geothermal energy generation costs remaining stable when gas and oil prices increase is an advantage, not a disadvantage.
• Option D: Geothermal energy is not weather - dependent. It can be generated throughout the year as it relies on the Earth's internal heat.

Answer:

B. Geothermal energy implementation in homes and businesses has a high upfront cost, and electricity is needed to operate pumps.
