Adam generating electricity from water flowing downhill is an example of how systems take advantage of energy flowing from low to high take advantage of energy flowing from high to low violate the second law of thermodynamics

The answer is the dam generates electricity taking advantage of energy flowing from high to low.

Explanation:

Basically, what the dam does is to store gravitational potential energy and converts it to kinetic energy. This conversion can be made since the water at one side is higher that the other side of the dam, therefore the higher side stores the potential energy and when it goes to the other side, the energy stored is converted to kinetic energy, which turn turbines generating electricity.
