Question

the image shows devices that convert solar energy into electrical energy. what is one advantage of using these devices in place of a nuclear power plant? a. they take up less space. b. they produce less hazardous waste. c. they have lower greenhouse gas emissions. d. they are more reliable.

Explanation:

• Option A: Solar farms (the devices shown) often require a large area of land, while nuclear power plants, although they have specific safety - related space requirements, in general, a single nuclear power plant can produce a large amount of electricity in a relatively compact area compared to the land - area - to - energy - output ratio of solar farms. So, solar devices do not take up less space.
• Option B: Nuclear power plants produce radioactive waste which is extremely hazardous and requires long - term, specialized storage. Solar devices, on the other hand, do not produce such highly hazardous waste. Solar panels may have some non - hazardous or less - hazardous waste at the end of their life (such as electronic components that can be recycled), but it is far less hazardous than nuclear waste.
• Option C: While nuclear power plants do not produce greenhouse gases during their normal operation (they produce radioactive waste instead), this option is incorrect because the question is about the advantage of solar over nuclear.
• Option D: Nuclear power plants can operate continuously (except for maintenance periods) and are very reliable in providing a steady supply of electricity. Solar devices are dependent on sunlight, so they are not as reliable in terms of continuous power generation as nuclear power plants.

Answer:

B. They produce less hazardous waste.
