A hydroelectric power plant uses water power to produce a useful form of energy. The diagram below shows the production of electricity using hydropower. During this process, energy causes several types of motion and change inside the power plant. Which of the following is NOT an example of a type of motion or change caused by energy

• water spinning the turbine

• water flowing from the reservoir to the plant

• electricity flowing from the generator through the power lines

• the concrete of the power plant supporting the turbine and generator
