plant?

Answer 1

Answer:

coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine.

Explanation:

A dam opens gates at the top to allow water from the reservoir to flow down large tubes called penstocks. The force of the flowing water spins the blades of a giant turbine. ... When water spins the turbine, it gains kinetic energy. The turbine is connected to a generator that makes electricity as it spins.
