The correct answer is: b) Minimal storage.
Run-of-the-river hydropower projects are a type of hydroelectric power plant that uses the natural flow of a river to generate electricity. They do not have large reservoirs, and instead use the water that is already flowing in the river. This makes them a more environmentally friendly option than other types of hydropower projects, which can have a significant impact on the environment.
Run-of-the-river hydropower projects have a number of advantages over other types of hydropower projects. They are relatively inexpensive to build and operate, and they have a low environmental impact. However, they also have some disadvantages. They have a lower power generation capacity than other types of hydropower projects, and their power output can vary depending on the flow of the river.
Overall, run-of-the-river hydropower projects are a viable option for generating electricity in a sustainable way. They are relatively inexpensive to build and operate, and they have a low environmental impact. However, they also have some disadvantages, such as a lower power generation capacity and variable power output.
Here is a brief explanation of each option:
- Option a) Large reservoirs: Run-of-the-river hydropower projects do not have large reservoirs. Instead, they use the natural flow of a river to generate electricity.
- Option b) Minimal storage: Run-of-the-river hydropower projects have minimal storage. This means that they do not store water in a reservoir. Instead, they use the water that is already flowing in the river.
- Option c) High power generation capacity: Run-of-the-river hydropower projects have a lower power generation capacity than other types of hydropower projects. This is because they do not have large reservoirs to store water.
- Option d) Constant power output throughout the year: Run-of-the-river hydropower projects have variable power output. This is because their power output depends on the flow of the river.
