I agree with most of the comments. The equipments for the solar power is expensive, and there are many issues about how to efficiently collect the solar power. However, I think that the solar power is still valuable to the human's life. Everyone would agree with me that the solar power is renewable and pollution-free. We must find a way to use it efficiently. The project, "Apple's solar strategies", is a great example of how to use the solar power efficiently. We should always try to discover and create new solutions. I believed that, in the future, humans will fully manipulate the solar power.
