V. Choose A, B, C, or D to indicate the option that is the best answer to each of the questions. Solar energy is a long-lasting source of energy, and it can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so we do not need any new space. Compared to other renewable sources, they also possess many advantages: wind and water power rely on turbines which are noisy, expensive and which take up large space. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime. 26. What is the passage mainly about?
