Hydroelectric dams are 90% or more efficient, meaning 90% or more of the original energy is converted into the final, usable form. But that still leaves up to 10% that isn't transformed. In the diagram above the locations of the two main sources of waste energy are marked with pink labels.Propose the forms of the waste energy from these locations. Write them into the diagram. Hint 1: One kind is created by friction in a machine.Hint 2: If you can't think of the second one, go to the next question – it might help.

State the form of energy that is transformed into kinetic energy in a hydro dam. Electrical Energy1Gravitational Potential Energy2Nuclear Energy3Heat Energy4

The hydro power plant transforms one form of energy into another. However, the total amount of energy of the water stays the same until it enters the turbine.Explain how this statement is supported by the three column charts above.

Drag each label to the correct location. Each label can be used more than once.In a hydropower station, water stored in dams is allowed to fall with force to make a turbine move. The turbine moves and produces electricity. In the diagram, identify the stages of transformation of energy in the hydropower station.gravitationalenergykineticenergyelectricenergy

Describe the form of energy that is transformed into electrical energy in a hydroelectric power station, and explain how the water gained its energy.

Select the correct energy flowchart that shows the production of hydroelectricity.
