Good morning, class. Today we'll continue our discussion on renewable energy. Specifically, I want to focus on solar power. While many people think solar panels are most effective in hot, sunny climates, research shows they actually work better in cooler temperatures. The efficiency of a solar panel decreases as the temperature rises above 25 degrees Celsius. So, countries like Germany, which have moderate summers, can generate more electricity per panel than, say, desert regions, despite less sunshine. However, the total energy output still depends on the amount of sunlight received. So, a balance between temperature and sunlight is crucial. Now, let's look at a case study from Spain.
