Sent 7: Moving Water Falling water can have a lot of energy.
Sent 8: Its energy can be converted into kinetic energy.
Sent 9: This energy can turn a turbine and generate electricity.
Sent 10: The water may fall naturally over a waterfall or flow through a dam.
Sent 11: A drawback of dams is that they flood land upstream.
Sent 12: They can also reduce water flow downstream.
Sent 13: Either effect may harm ecosystems.
Sent 14: Wind Wind is moving air.
Sent 15: It has kinetic energy that can do work.
Sent 16: Wind turbines change the kinetic energy of the wind to electrical energy.
Sent 17: Only certain areas of the world get enough steady wind.
Sent 18: Many people also think that wind turbines are noisy and not very nice to look at.
