Explore the energy transformations that take place in various methods of generating electricity and then assess their impacts.
Energy is conserved and its transformation can affect living things and the environment.
Students will be able to:
Which factors are the most important in determining the potential energy of a dam?
Electricity is generated from water by using the potential energy stored in reservoirs behind dams. The water flows down and through a large tube, called a penstock. The potential energy becomes kinetic energy because the water is, effectively, falling. That kinetic energy from the fast-moving water pushes blades inside turbines, which cause generators to turn.
The amount of electricity a hydropower plant could produce initially depends on two factors:
