Good morning. Today we're discussing renewable energy sources. Specifically, we'll focus on solar power. While solar panels are widely used, their efficiency depends on several factors, including geographical location and weather patterns. For instance, in northern Europe, solar panels generate less electricity in winter due to shorter daylight hours. However, recent advancements in battery storage have made solar energy more reliable even in cloudy regions. A study from the University of Oslo shows that combining solar with wind power can stabilize energy supply. Therefore, many experts recommend a hybrid approach rather than relying solely on one source.
❓ What does the lecturer say about solar power in northern Europe?
A. A. It is more efficient in winter due to cold temperatures.
B. B. It produces less electricity in winter because of shorter daylight hours.
C. C. It is unreliable and cannot be used at all in cloudy regions.
D. D. It has been replaced by wind power in most areas.
✅ 正确答案
B. It produces less electricity in winter because of shorter daylight hours.
