this book helps me learned about why should we use solar energy more often and how is using more solar energy helpful for our planet and I also know that using solar energy save more money because solar energy is a free source, no one owns the sun. But there is also bad things because solar energy is base on the sun so if it's a rainy day or there is no sunlight then we can't or we don't have the energy to cool or heat things. it is interesting because it also tell us how they get the solar energy and where do they get them.
