Read the following passage and answer the question below. Solar energy has emerged as one of the most promising alternatives to fossil fuels in the fight against climate change. Solar panels convert sunlight directly into electricity using photovoltaic cells, a technology that has become significantly cheaper and more efficient over the past two decades. Countries around the world are increasingly investing in large-scale solar farms as well as rooftop panels for homes and businesses. Unlike coal or natural gas, solar power produces no direct emissions during operation, making it an environmentally friendly option. However, challenges remain, including the intermittent nature of sunlight, the need for efficient energy storage systems, and the environmental impact of manufacturing panels. Despite these challenges, many experts believe that continued technological advancement and falling costs will make solar power one of the dominant sources of electricity within the coming decades. Question: Which of the following is mentioned in the passage as a challenge facing solar energy?
- A. The lack of public interest
- B. Legal restrictions in most countries
- C. The intermittent nature of sunlight ✓
- D. The high cost of sunlight
Correct answer
C. The intermittent nature of sunlight
Explanation
The passage lists the intermittent nature of sunlight as one of the remaining challenges for solar energy.
