Read the following passage then choose the best answer to each question below.
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! It is easy to install solar cells on house roofs so each user can quietly generate their own energy from home. Compared to other renewable sources, they also have many advantages. Wind and water power rely on turbines but they are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. Because they have no moving parts, they only require a little money to maintain and have a long lifetime.
However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require a large area to work effectively. Moreover, solar energy costs about twice as much as traditional sources such as coal, oil, and gas. Scientists hope that the costs of solar cells will reduce in the future for people to use this environmentally friendly source of energy more.
- Advantages and disadvantages of solar energy
- Solar energy's advantages over other sources of energy
- The cost of solar energy
