Jaydin Mcdonald · Answer 1

There are multiple transformations of energy. When lake water flows downward through tunnels, its potential energy is converted into kinetic energy. Then the flowing water turns turbines and its kinetic energy is transformed into mechanical energy. Turbines generate electricity by transforming mechanical energy into electrical energy.

Kenley Hayden · Answer 2

Lake water flows downward through tunnels

- water's gravity PE to water's KE

Flowing water turns turbines

- water's KE to turbines' KE

Turbines generate electricity

turbines' KE to electrical energy.
