Question

select the correct answer.
whats the disadvantage of using solar energy instead of energy from fossil fuels?
a. the amount of sunlight varies throughout the day.
b. solar energy panels are ineffective in tropical regions.
c. excessive use of solar energy leads to pollution of the atmosphere.
d. use of solar energy leads to climate change.

Explanation:

• Option A: Solar energy depends on sunlight. Since the amount of sunlight varies throughout the day (e.g., no sunlight at night), solar - energy - based power generation is intermittent. This is a valid disadvantage compared to fossil - fuel - based energy which can be used more consistently (as long as there is fuel).
• Option B: Tropical regions generally receive a large amount of sunlight. Solar energy panels are actually quite effective in tropical regions due to the high solar irradiance. So, this option is incorrect.
• Option C: Solar energy is a clean energy source. It does not lead to atmospheric pollution during its operation (unlike fossil fuels which release pollutants like \(CO_2\), \(SO_x\), \(NO_x\)). So, this option is incorrect.
• Option D: Solar energy does not contribute to climate change. In fact, it is a renewable energy source that can help mitigate climate change by reducing the use of fossil fuels (which are major contributors to climate - change - causing greenhouse gas emissions). So, this option is incorrect.

Answer:

A. The amount of sunlight varies throughout the day.
