It seems like you might be looking for a comparison of the kinetic energy generated by water falling in different types of dams or possibly specific figures related to energy generation. However, the numbers you've provided (115, 300, 200, 75) are not clear in context—whether they refer to kilowatts, megawatts, or some other unit of measure, and how they relate to specific dam types or configurations.
If you can provide more context or clarify your question, I’d be happy to assist you further!
