This water has served its purpose, and leaves the power generation unit or water wheel area.. In hydroelectric dams, the tail race is at a much lower level than the height of the ...
A thermal power plant is a power station that converts heat energy into electric power. These power plants do this by primarily heating fossil fuels, which heats up water into steam. The steam moves through a turbine, which generates the electricity, and then it is condensed and recycled back to its pre-heated starting point.
