Final answer:
Water stored in dams falls freely, gaining kinetic energy and producing electrical energy.
Step-by-step explanation:
The types of energy in the given system can be sorted as follows:
- The water stored in dams has potential energy
- As the water falls and moves the turbine, it gains kinetic energy
- The turbine produces electrical energy
- Finally, the electrical energy is used at homes for heating, cooling, and lighting (which are forms of light energy).
