To determine the author's point of view on solar energy, we would need to analyze the context of the original text. However, based on common perspectives around solar energy, the following options are generally seen as favorable towards solar energy:
A. Solar energy has environmental benefits. E. Use of new materials may have long-term benefits for solar energy. F. Even a small-scale use of solar energy aids the effort to help the environment.
Options B, C, and D express skepticism or negative viewpoints about solar energy. Therefore, they would not align with a positive point of view.
If you have specific details or excerpts from the text, I could provide a more tailored analysis.
