Hydroelectricity and Types of Energy

APES-UJYYMG

Which of the following correctly describes the type of energy produced by a hydroelectric power plant like Three Gorges Dam in China?

A

Like other hydroelectric dams, this one produces electricity (a form of potential energy) by taking advantage of kinetic gravitational energy.

B

Like other hydroelectric dams, this one produces electricity (a form of kinetic energy) by taking advantage of potential gravitational energy.

C

This dam produces more electricity than any other because it takes advantage of both potential electrical energy as well as potential chemical energy.

D

Like all power plants, this one uses potential chemical energy to produce kinetic electrical energy.

E

This dam produces electricity by harnessing both the power of water and of wind.
